The Chevrolet Tahoe (and its rebadged version GMC Yukon) is a full-size luxury SUV from General Motors. Chevrolet and GMC sold two different-sized SUVs under their Blazer/Jimmy model names through the early 1990s. This situation changed when GMC rebadged the full-size Jimmy as the Yukon in 1991. Chevrolet waited until 1994 to rebadge the redesigned mid-size S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe. The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States. The name Yukon refers to the Yukon territory of northern Canada. For the 1995 model year, the Tahoe and Yukon gained a new 4-door model slotting in size between the 2-door models and the longer wheelbase and higher passenger capacity to up to 9 nine passengers like the Chevrolet Suburban and newly named Yukon XL.
The Insurance Institute for Highway Safety has praised the Tahoe as one of the best of its class. The Tahoe is sold in North America, The Middle East (Except Israel), Republic of China (Taiwan), The Philippines, Chile, Russia, and Europe (Except U.K./Ireland) as a Left-hand vehicle. The Yukon and Yukon Denali is sold in United States, Canada, Mexico, Republic of China (Taiwan), the Middle East (Except Israel), Russia, The Philippines, Chile, and Europe (Except U.K./Ireland) in LHD.
The Chevrolet Tahoe and GMC Yukon currently serve as a part of General Motors' full-size SUV family. Lengthened wheelbase models are available for both as the Suburban for Chevrolet and Yukon XL for GMC. A luxury Denali model joined the Yukon lineup in 1998. As of 2002, a Denali version of the Yukon XL has also been available as the Yukon XL Denali. The Cadillac Escalade is closely related to the Denali models of the Yukon. As of February 2014, the 2014 Tahoe was the top-ranked Affordable Large SUV in U.S. News & World Report's rankings.
Maps, Directions, and Place Reviews
First generation (1992-2000)
The new GMC Yukon was introduced in 1991 for the 1992 model year, while GM had continued to produce the Chevrolet K5 Blazer until 1994. All were 2-door models through 1994. The Chevrolet K5 Blazer was discontinued after the 1994 model year. The Chevrolet Tahoe was introduced in 1995 for the 1995 model year with the addition of an all-new 4-door version. The Tahoe was Motor Trend magazine's Truck of the Year for 1996. It is named from Lake Tahoe on the California-Nevada border in the United States.
The Tahoe/Yukon were shorter than the Suburban on which they were based, but shared that vehicle's GMT400 platform. This was a true truck chassis, and was based on that used in the Chevrolet Silverado full-size pickup truck. Both two-door and four-door models were produced in rear- and four-wheel drive. The two-door weighs roughly 4,500 lb (2,041 kg) while the four-door weighs approximately 5,500 lb (2,495 kg). "AutoTrac" full-time all-wheel drive and a programmable Homelink transmitter were added for 1998. The upscale Denali trim line to the Yukon was introduced in 1999 as these vehicles became popular with wealthy families.
The standard engine was Chevrolet's 5.7 L (350 cu in) LO5 small-block V8, while a turbocharged 6.5 L (395 cu in) Detroit Diesel V8 was available beginning in 1994.
In Mexico, the Tahoe 2-door was released in 1995, called the Chevrolet Silverado, and in 1998 the 4-door was released as the Silverado 4-door, and both were available in Base, LS and luxury LT trim lines. In Venezuela, the Tahoe 2-door was released in 1993 (4WD only), called the Chevrolet Grand Blazer, and in 1996 the 4-door was released as the Grand Blazer 4-door (2WD). In 1996 the 2-door was discontinued. In 1996 only Grand Blazer 4-door 4WD was available. In Bolivia, 1995 the 4-door was released as the Tahoe 4-door (4WD).
Beginning in 1994, GM began making numerous annual changes to the Blazer/Yukon, including:
- Revised front clip - Blazer (1994)
- Revised interior including a driver-side air bag, revised side mirrors, Blazer renamed Tahoe, 4-door option included (1995)
- Revised Vortec 5700 (350 cu in) engine with increased power and fuel efficiency, electronic 4WD shifting, daytime running lights, illuminated entry, and some new interior features (1996)
- Revised automatic transmission, improved steering system and added passenger-side air bag, Yukon 2-door option dropped (October 1996)
- Programmable Homelink transmitter, PassLock security system, heated front seating surfaces optional, air conditioning for rear seat passengers, AutoTrac automatic 4WD option added, second generation air bags, transmissions revised again (1998)
- Revised steering wheel and improved radiators and transmissions, Tahoe 2-door option dropped (1999), side curtain airbags for all three rows (when equipped with 3rd row) and front and rear side torso airbags (optional); combination head and torso side airbag (without 2nd and 3rd rows, optional)
Tahoe Limited and Tahoe Z71
When the GMT800 platform based Chevrolet Tahoe/GMC Yukon was released for the 2000 model year, a 2WD Tahoe Limited and 4WD Tahoe Z71 remained in production on the GMT400 platform as special edition vehicles. These special edition vehicles were produced in the Arlington, Texas assembly plant for the 2000 model year only.
The Chevrolet Tahoe Limited was based on the Chevrolet Tahoe SS concept vehicle introduced in 1996 that never made it to production. It is reported that GM disliked the idea of an SS badged vehicle at a time when insurance companies were already demanding higher premiums for SUVs. The Tahoe SS prototype vehicles made in 1996 were painted either an unspecified metallic green or metallic blue, but the Tahoe Limited was produced only in black onyx metallic. The Tahoe Limited had a distinctive exterior appearance that included a factory equipped ground effects, a monochromatic theme with bumpers and grille painted in the same high gloss black as the body, removal of the roof rack, and fog lamps integrated into the front bumper. Other notable features of the Tahoe Limited included the Z60 high-performance chassis package (commonly known as the police package) which places the body of the vehicle 2 in (51 mm) lower than the 4WD Tahoe, two tone gray and charcoal leather interior seating surfaces, a 120 mph (190 km/h) gauge cluster, 46 mm (1.8 in) Bilstein shock absorbers, a 3.42 or optional 3.73 rear gear ratio, a limited slip rear differential, an engine oil cooling system, and distinctive 16 in Ronal R36 five-spoke aluminum wheels.
The Chevrolet Tahoe Z71 also exhibited a monochromatic appearance similar to the Tahoe Limited, but instead of black onyx metallic the Tahoe Z71 was offered in either light pewter metallic, victory red, emerald green metallic, or indigo blue metallic. Features of the Tahoe Z71 were similar to those of the Tahoe Limited with a few key differences to distinguish the 2WD Tahoe Limited from the 4WD Tahoe Z71. Features that differ from those previously mentioned on the Tahoe Limited included the Z71 off road chassis package (46 mm (1.8 in) Bilstein shock absorbers, a standard 3.73 rear gear ratio G80 locking differential), body colored wheel flares, trim, grille and bumpers, inset driving lights built into the center of the front bumper, oversized two row radiator, two tone leather seating surfaces in either a gray or neutral theme, distinctive tail lamp lens covers, black tubular side assist step bars, black brush guard, and distinctive 16 inch Alcoa five spoke 6 bolt polished aluminum wheels.
The L31 5.7 L Vortec V8 powerplant and 4L60E four-speed automatic transmission shared with other GMT400 Chevrolet Tahoe vehicles were not modified in these special edition vehicles, and as such these special editions were mostly appearance packages.
Second generation (1999-2006)
Other than the Tahoe Limited Edition, the vehicle was redesigned for the 2000 model year on the new GMT800 platform, still shared with the full-sized pickups and SUV's. Two new engines replaced the old 5.7 L (350 cu in) small-block V8, and while both were smaller, both produced more horsepower but less torque. The manual transmission was dropped, leaving only the automatic transmission. In Mexico, the GMT800 Chevy Tahoe is called a Chevrolet Sonora. A 2-door GMT800 Tahoe prototype was made but never entered production.
Both vehicles received significant updates with only the grille and headlights distinguishing one from the other. Both vehicles now featured softer lines as part of a more aerodynamic design. The interior was also updated with new seats, dashboard, and door panels.
For 2003, all GM full-size trucks received an upgraded interior, including a new steering wheel and radio controls, along with better-quality materials and other enhancements. StabiliTrak stability control was also offered for the first time in 2003 (came standard on 2006), as were XM Satellite Radio, Bose audio, and a DVD entertainment system as the models continued to climb upmarket. Both engines received 10 hp (7 kW) more for 2003 and 2004. The Flex Fuel engine became available first in the 2002 model.
Engines
Third generation (2006-2014)
General Motors redesigned the Tahoe and Yukon on the new GMT900 platform in late 2005 as a 2007 model. A hybrid version of the Yukon, which uses the shared GM/Chrysler Advanced Hybrid System 2, followed with the 2008 models. The GMT900 based Tahoe and Yukon exceeded initial sales expectations and continued to sell well despite a weakening market for large SUVs. The short-wheelbase Tahoe and its police counterpart began production at Arlington Assembly on December 1, 2005. SWB Yukon production began in early 2006, with Janesville Assembly coming on line as well. Long-wheelbase versions began at Janesville and Silao Assembly in March. For the first time, GM used the Tahoe name in Mexico.
For 2007, the GMC Yukon and Chevrolet Tahoe received different front fascias, hood, and tail lights. The GMC Yukon boasted a monolithic grille and headlights, while the Chevrolet Tahoe grille was divided by a body colored bar similar to the chrome bar found on most GMT800 Tahoes. Both the redesigned Yukon and Tahoe featured a more angular design that gave the vehicles a more upscale appearance than their predecessors. The interior was significantly redesigned as well, features a real wooded trim dashboard with new chrome accented instrument controls. New door panels as well as new seats were also added to the interior it still retains its nine-passenger seating availability on LS and SLE models only like the Chevy Suburban and GMC Yukon XL.
In 2006, the newly redesigned Tahoe was featured on, and promoted through Donald Trump's The Apprentice, where the two teams put together a show for the top General Motors employees to learn about the new Tahoe. Also, The Apprentice sponsored a controversial online contest, which allowed the public to create their own 30-second ad in hopes of winning a new Tahoe.
Highway mileage was improved from 19 mpg-US (12 L/100 km; 23 mpg-imp) to 21 to 22 mpg-US (11 to 11 L/100 km; 25 to 26 mpg-imp) with the addition of Active Fuel Management cylinder deactivation. For 2009, the 6.2 L engine in the Yukon Denali got a power increase to 403 hp (301 kW), while a 395 hp (295 kW) 6.2 L was added as an option for the Tahoe LTZ. A 6-speed 6L80 automatic transmission replaced the 4-speed on all trucks except 2WD models with the 4.8 L engine. The 2011 model has a NHTSA rollover risk of 24.6%, and a lateral roadholding of 0.79g.
2009 LTZ Models had the option of the 6.2 L Vortec 6200 this was only an option in 2009 and only in the LTZ trim.
2010 models underwent a mild mid-cycle refresh including a slightly raised bumper, revised door trim, improved side structure, and side torso air bags. For 2012, the GMC Yukon, underwent minor changes: the SLE and SLT grades were discontinued, in favor of appearance packages.
The Apprentice make-your-own-ad contest
In 2006, the 2007 Tahoe was featured on and promoted through Donald Trump's TV series, The Apprentice, where the two teams put together a show for the top General Motors employees to learn about the new Tahoe. Also, The Apprentice sponsored a controversial online contest in which anyone could create a 30-second commercial for the new Tahoe by entering text captions into the provided video clips; the winner's ad would air on national television. An early example of User generated marketing, headed by ad agency Campbell Ewald, the campaign began to backfire when hundreds of environmentally conscious parodies flooded YouTube and Chevy's website critiquing the vehicle for its low gas mileage. Over 400 negative ads were created in total, however over 20,000 positive ads were created making the campaign, according to Chevrolet, a success, despite the negative media attention.

Fourth generation (2015-present)
The Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL, Cadillac Escalade, and Cadillac Escalade ESV had a shortened 2014 model year starting in June 2013, and was replaced with a new version in February 2014 as a 2015 model. The 2015 Tahoe/Yukon was supposed to be based on the next-generation Chevrolet Silverado, which was introduced in May 2013. Rumor was that the vehicles could go to monocoque crossovers; those were shelved, as General Motors plans to add to the traditional body-on-frame truck-based SUV, as the 2012 Chevrolet Colorado-based Trailblazer debuted in 2013 for international markets, the Colorado debuting in 2014 for North America (as a 2015 model), and truck owners wanting a smaller truck-based SUV, instead of the monocoque crossover. GM's citing of healthy sales for their full-size SUVs in 2012 was another reason to retain the BOF platform.
The Tahoe and Yukon are now built on the GMT K2XX platform and assigned as K2UC (for Chevrolet Tahoe) and K2UG (for GMC Yukon). Production on the Tahoe and Yukon began in December 2013 with the first completed SUVs being used for testing purposes, and started officially shipping the vehicles to dealerships on February 5, 2014. The 2015 Tahoe was later named the fastest-selling vehicle for the month of February 2014, averaging seven days of sales upon its release. like the 2007-14 version they do not share any sheetmetal and lighting elements with the brand's full-size pickup trucks (GMC Sierra and Chevy Silverado) each one is altered and changed to have its own distinct identity.
On September 12, 2013, GM released photos and press release of the fourth-generation Tahoe and Yukon. Like its larger siblings Suburban and Yukon XL, the front fascias of the Tahoe and Yukon are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, improving aerodynamics and fuel economy, and lessens interior noise. The hoods and liftgate panels now are made of aluminum in an effort to reduce vehicle weight. A more-efficient, direct-injected EcoTec3 powertrain coupled with improved aerodynamics help increase fuel economy for the SUVs. Both fourth-generation SUVs do not share a single piece of sheetmetal or lighting element with the brands' full-size pick-up trucks, and the front grilles of both vehicles are slightly altered to give them their own identity. The front headlights features projector-beam headlamps that flanks the Chevrolet-signature dual-port grille - chrome on all models, sweeping into the front fenders, while the LTZ trims feature high-intensity discharge headlamps and light-emitting diode daytime running lamps.
Also new are the addition of fold-flat second- and third-row seats, now a standard feature but can be equipped with an optional power-folding feature for the upgraded trims, and an additional two inches of leg room for second-row passengers. Multiple USB ports and power outlets are now spread throughout their interiors, including one 110-volt, three-prong outlet, with the Tahoe adding an available eight-inch color touch-screen radio with next-generation MyLink connectivity along with an available rear-seat entertainment system (but will not feature a Blu-ray option that is exclusive to the Suburban for 2015), while the Yukon added a standard eight-inch-diagonal color touch screen radio with enhanced IntelliLink and available navigation.
The Yukon interior has more features including seats stuffed with dual-firmness foam, a standard Bose sound system and SD card slots, and laminated glass for the windshield and front windows, decreasing interior noise. GM's third-generation magnetic ride control suspension is optional on the Tahoe LTZ models, whose upgraded features include third-generation magnetic ride control, a real-time damping system that delivers more precise body motion control by "reading" the road every millisecond, and changing damping in just five milliseconds.
The new platform is based on the 2014 Chevrolet Silverado 1500 and GMC Sierra 1500. Both SUVs feature sound deadening material to improve cabin quietness. A new Cadillac Escalade and Cadillac Escalade ESV arrived in dealerships in April 2014. Models continued for the Tahoe and Suburban as LS, LT, and LTZ, and the Yukon and Yukon XL as SLE, SLT, and Denali. The Tahoe and Yukon went on sale in February 2014 as an early 2015 model year vehicle. Prices for the all-new GM SUVs are expected to stay the same as the current-generation GMT900 SUVs. The Tahoe Hybrid, Yukon Hybrid, and Yukon Denali Hybrid models will be dropped along with their powertrains, as well as the Cadillac Escalade Hybrid and Cadillac Escalade Hybrid Platinum. The Yukon Denali AWD is also being dropped as well. And despite reports that it is under consideration at this point, GM is mulling plans to bring the SS and RS package back for the Tahoe.
On August 29, 2014, Chevrolet announced that the Z71 package would return with a launch by leaking a photo that displayed the Z71 badge on one of its large SUVs. On September 26, 2014, Chevrolet debuted the updated Z71 Tahoe at the State Fair of Texas, along with the debut of the Texas Edition Tahoe, the latter due to Texas having the largest units of Tahoes sold in the United States (as of August 2014, sales of the Chevrolet SUVs in Texas were up 37 percent) and to celebrate the 60th anniversary of GM's Arlington Assembly plant; production began in October 2014. As with the previous Z71 Tahoe, this version will continue to be offered in a 4WD LT trim only, featuring a front skid plate, off-road tires mounted on 18-inch wheels, a unique grille, running boards and "Z71" identification inside and out. Fog lamps, front tow hooks and front parking assist are also included. The Texas Edition will be available in both LT and LTZ trims, featuring a maximum trailering package, twenty-inch polished aluminum wheels (on LT models), twenty-two-inch premium painted aluminum wheels (on LTZ models), and an exclusive "Texas Edition" badge. The Texas Edition Tahoe package will be part of a lineup that will also use the Texas Edition package, alongside the Suburban and Silverado.
On March 23, 2014, a 2015 GMC Yukon caught fire and went up in flames in Anaheim, California, after a couple, who along with the sales representative who were giving them a test drive, noticed the vehicle stopping and that smoke was starting to make its way into the cabin, prompting the three individuals to park the car and escape before it was destroyed within 15 minutes. The cause of the fire was traced to an oil leak and an engine malfunction. Despite being an isolated incident, the 2015 Tahoe and Yukon are not believed to be tied to GM's announced recall of its vehicles that was made on March 17, 2014. But five days later on March 28, 2014, GM announced a recall on the 2015 Tahoe and Yukon in order to fix a "transmission oil cooler line that is not securely seated in its fitting", causing the vehicle to stop and rupture the oil cooling line, resulting in the engine to malfunction and catching fire immediately. On June 6, 2014, GM issued another recall on the 2015 Tahoe and Yukon because their radio control modules may not work, and thus prevent certain audible safety warnings.
The demand and interest in the redesigned Tahoe has also translated into a 108 percent sales spike since it went on sale in February 2014, with most dealers reporting the units being sold within 17 days after they arrive on the dealership lots with customers opting for the fully loaded LTZ model, making it one of Chevrolet's fastest selling brands in 2014 along with Suburban, who posted higher sales and quicker inventory turnovers.
2015 mid-year update
The Tahoe received 4G LTE, WiFi, and Siri capability, a new color palette, Brownstone Metallic, and added a hands-free power liftgate feature that is standard on LTZ, but included on LT with the optional Luxury Package. The MyLink with Navigation feature became standard on the LTZ trim, while E85 capability is removed from retail orders.
The Yukon, in addition to receiving the aforementioned features, sees the 6.2-liter EcoTec3 V8 engine being updated with the new 8L90E eight-speed automatic transmission for the interim model year, allowing it to improve fuel economy.
2016
For the 2016 model year, the Chevrolet Tahoe received more upgraded changes and new features, similar to the ones added to the Suburban. The changes included power-adjustable pedals, forward collision alert, IntelliBeam headlamps, lane keep assist and a safety alert seat as part of the newly introduced enhanced driver alert package as an available option on the LS trim. The inside floor console with storage area-SD card reader was removed and a new infotainment system was introduced, officially ending the CD player era for the Tahoe; the 8-inch MyLink feature was expanded to the LS trim and became standard (replacing the 4-inch display), although the navigation feature remains as an option on LT and standard on LTZ. A new liftgate shield was added to the Theft Protection Package, along with the new lane keep assist which replaced the lane departure warning. The capless fuel fill tanks became standard on all trims. Siren Red Tintcoat and Iridescent Pearl Tricoat became the new color trims, replacing Crystal Red Tintcoat and White Diamond Tricoat. The instrument cluster was re-configured with a new multi-color enhancement and a heads-up display was introduced as a standard only on the LTZ trim.
The 2016 GMC Yukon also sees similar changes, with liftgate, power, hands-free now packaged on SLT trims, a free-flow feature that replaced the Premium package, and two new premium colors (Crimson Red Tintcoat and White Frost Tricoat) replacing Crystal Red Tintcoat and White Diamond Tricoat respectively.
On May 27, 2015, Chevrolet announced that the 2016 Tahoe will come equipped with both Apple CarPlay and Android Auto Capability features. However, only one of their phone brands at any one time can be used. The 2014 and 2015 LTZ and Denali packages come equipped with a "wireless" charging accessory. while the Android Auto option will only be available on LT and LTZ trims featuring 8 inch screens.
On July 10, 2015, GM announced that the Russian-built Chevrolet Tahoe will receive the 6.2L V8 L86 EcoTec engine, which will be the only engine offered in the region as an exclusive to the Russian and CIS markets only, as GM has no plans to make it available to North America for the time being.
2017
For the 2017 model year, Chevrolet made upgraded changes to the Tahoe. New additions include the teen driver feature, the App Store feature, a rear seat reminder, and low speed forward automatic braking. Two new colors, blue velvet and pepperdust metallic, were added to replace four colors. The 22-inch wheels option was expanded to three, and the rear seat entertainment system was overhauled. Chevrolet also made changes in the level trims, with the standard LS badge now removed from all LS models and the LTZ trim is phased out and renamed Premier, which will continue to be the top of the line model.
The 2017 model year Yukon also received similar changes, but with a few exceptions. Two new colors, Dark Blue Sapphire Metallic and Mineral Metallic were introduced, the latter exclusive to the Denali, which is also adding a new 22-inch ultra bright aluminum wheels with midnight silver premium paint and a head-up display to its features. The interior backlights changed from red to blue. The heated and vented driver and front passenger seats are now standard on the SLT and Denali trims.
GMC Yukon Denali
The GMC Denali nameplate started as the luxury version of the Yukon for the 1998 model year. The Denali is available on both standard and XL versions, and is the top-of-the-line trim in the GMC Yukon lineup.
1999
In 1998, at the time of its introduction, the Yukon Denali was GM's answer to the Lincoln Navigator, but then GM introduced a clone to the Yukon Denali and rebadged it "Escalade" under the Cadillac nameplate. The Yukon Denali's exterior was shared with the Cadillac Escalade, with the entire front clip and lower side body panels differing from the standard Yukon. In the interior, in addition, the Denali features luxury options not available in the Yukon. These included an upgraded leather interior, power seats, heated seats front and rear, Bose stereo system, and some woodgrain on the dashboard.
2001-2006
Even though the Yukon was redesigned alongside the Chevrolet Suburban and Tahoe in 2000, the Denali and Escalade retained their 1990s base design. It was not until 2001 that the Denali and Escalade were redesigned. While the Escalade departed from its Yukon based exterior design scheme in attempt to hide its roots, the Yukon Denali's exterior is almost the same as that of a post-2000 model year GMT800 Yukon. Embossed side body panels and slightly reworked headlights with projector-beam lenses along with 17" polished wheels and different grille and front bumper differentiate the Yukon Denali from the regular Yukon. 2001 also saw the introduction of the billet grille which now has become the hallmark of the Denali nameplate.
2007-2014
The Yukon Denali was redesigned for the 2007 model year alongside the regular mainstream Yukon. The biggest change was in the styling, such as the flattened tailgate reminiscent of the new Tahoe, and particularly the grill and headlight shapes, which made the Yukon look less aggressive than previous models. The only exterior difference between the Yukon Denali and the standard Yukon are the chrome grille and extensive use of chrome accents; and of course the insignias, embeveled rockerpanels, chromed headlights and the Vortec 6200 engine which it shares with the Cadillac Escalade.
2015-present
The Yukon Denali was redesigned and updated along with other GM SUVs in September 2013 and went to dealerships on February 5, 2014 as a 2015 model. The Denali Yukon continues with the top-of-the-line features (using the similar features found in the Tahoe LTZ trim) and the front grille honeycomb design, equipped with a new active noise-cancellation technology and GM's third-generation magnetic ride control suspension as a standard feature. In November 2014 The Yukon Denali saw its MSRP bumped up by $1,300 in part due to the loaded features added to its 2015 mid-year updates.
Hybrid vehicle
The Tahoe made its hybrid electric debut in late 2007. In January 2008, starting price was US$50,540. The starting price of the 2009 model was increased to US$51,405.
The Chevrolet Tahoe Hybrid uses a combination of its dual displacement 3.0/6.0 L V8 engine and two 60 kW (80 hp) (continuous) electric motors that charge a 300-volt nickel-metal hydride battery. The vehicle can run on either gasoline, electricity or a mixture of the two using automatic Two-Mode Hybrid system that monitors the vehicle's torque, and state of the battery to choose the most efficient source of power. The battery is charged either directly by generating electricity through driving one or both electric motors using the gasoline engine (while the vehicle is coasting or being driven by the gasoline engine), or by the wheels driving one or both electric motors through what is called "Regenerative braking" when the vehicle is decelerating, thus regaining some of the energy invested in forward momentum. The Tahoe is considered a strong or full hybrid, in that it can run entirely on the battery (for a limited range) at low speeds. In city driving, the EPA rating of fuel consumption for the 2WD version of the hybrid is 21 mpg-US (11 L/100 km; 25 mpg-imp). In comparison, non-hybrid varieties of the Tahoe are rated no higher than 15 mpg-US (16 L/100 km; 18 mpg-imp) in city driving. In highway driving, the EPA rating is 22 mpg-US (11 L/100 km; 26 mpg-imp).
The Tahoe and Yukon Hybrid models were discontinued after the 2013 model year as GM moved to make their SUVs more fuel efficient with the introduction of the EcoTec engine that they would later install in the 2015 Tahoe and Yukon.
The Tahoe outside the United States
In Brazil the Tahoe GMT400 was sold under the name of "Grand Blazer", sourced from Argentina with rear-wheel drive only, regionally-sourced 6-cylinder engines (the late-type 4.1 M.P.F.I. Chevrolet straight-6 as the only gasoline-powered option and the 4.2L MWM Sprint 6.07T for those who preferred Diesel) and manual transmission. The GMT400 is used by Brazilian elite police units, such as the BOPE (Batalhão de Operações Policiais Especiais) in Rio de Janeiro and the ROTA (Rondas Ostensivas Tobias de Aguiar) and GATE (Grupo de Ações Taticas Especiais) in São Paulo. It is also used by the São Paulo State Police and the Rio Grande do Sul State Police. But as the cars grew old, the great majority of them were substituted, mainly by the smaller Chevrolet Blazer midsize SUV, the locally imported Ford Crown Victoria and Ford Police Interceptor Sedan. The Tahoe name was not used in Brazil because it would be unfamiliar to most Brazilians since it refers to the Lake Tahoe on the border of Nevada and California.
Another South American Country such as Chile have incorporated this vehicle as transport unit for special operations unit (GOPE) of the Chilean Police (Carabineros de Chile) to carry communication equipment.
The Tahoe was also assembled in Venezuela from CKD kits for 3 generations, being phased out in 2014 along most of the local Chevrolet range due to unfavorable economic conditions and political circumstances. The 4th generation of the Tahoe has not been available in Venezuela.
In Ecuador, due to fiscal benefits to hybrid vehicles, the 3rd generation of the Tahoe had been offered only in the Hybrid versions until 2011. A review of the benefit to exclude hybrid vehicles with a displacement greater than 1.8L rendered the Tahoe Hybrid less cost-effective than the non-hybrid in Ecuador.
Police package
In North America, the Tahoe is used by many law enforcement agencies, fire departments, and EMS agencies. Prior to the announcement of the Z56 police package model the civilian base & LS models based on the GMT400 were used in police service. During the 1997 model year, the Tahoe was offered with the Z56 police option using suspension components from the discontinued 454SS truck - the first Tahoe Z56s were available only in 2WD until the GMT400 was phased out. The original prototype had rear disc brakes based on the B-body 9C1s whereas the production Z56s came with rear drum brakes. Plans for outfitting the Tahoe with the Z56 police package originated around the 1994 model year when GM broke news about phasing out its B-platform sedans (Caprice, Impala SS, Roadmaster) at the end of the 1996 model year where a replacement was imminent since GM ended production of its body-on-frame passenger sedans due to SUV sales. Since the introduction of the GMT900, Chevrolet currently offers two versions of the police package Tahoe; a four-wheel-drive version and a two-wheel-drive version. Just like the GMT400 based models civilian GMT800 Tahoe base & LS models were also used for police use until the Z56 police package option was reintroduced in 2004 late in the GMT800's life cycle by some agencies.
Chevrolet refers to the four-wheel drive (4WD) version as "Special Service Vehicle" (SSV) which has the 5W4 code. This version of the Tahoe can be used for all purposes except pursuits and high speed responses due to its high center of gravity just below the front window (height, not location), thus having a higher probability of rolling-over at high speeds. This version is preferred by agencies where snow, ice, flooding, rough terrain, and ground clearance are common issues.[34]
Chevrolet refers to the two-wheel drive (2WD) version--also known as the rear-wheel drive (RWD) version--as "Police Pursuit Vehicle" (PPV). This version be used for all purposes including pursuits and high speed responses. The center of gravity in this vehicle is lower than that of the four-wheel-drive version and the ground clearance is about 1 in (25 mm) less, with a standard rear bumper replacing the tow hitch on civilian Tahoes. Highway patrol agencies prefer the two-wheel-drive version, where pursuits and long distance responses are more common. It should be noted that the two-wheel-drive Chevrolet Tahoe is the only pursuit-rated SUV on the market today, and as of the 2012 model year, the last body-on-frame, rear-wheel drive police vehicle manufactured for the United States market since Ford phased out its aging Panther platform while the Volvo XC90-based Ford Police Interceptor (known as the Ford Explorer in civilian trim) is a monocoque chassis sourced from a Geely sedan, a wagon form of the Ford Taurus. Other SUVs like the Ford Expedition are used by many law enforcement and EMS agencies, but are not pursuit rated.[35]
On November 11, 2013, Chevrolet announced that they will build a 2015 Chevrolet Tahoe Police Patrol Vehicle, that was previewed as a concept at the 2013 SEMA show in Las Vegas. The vehicle became available in 2WD and 4WD drivetrains with orders coming in the first quarter of 2014 for special service models, followed by the orders for the police pursuit models afterwards.
Military applications
When production of the CUCV II ended in 2000, GM redesigned it to coincide with civilian truck offerings. The CUCV nomenclature was changed to Light Service Support Vehicle in 2001. In 2005, LSSV production switched to AM General, a unit of MacAndrews and Forbes Holdings. The LSSV is a GM-built Chevrolet Silverado 1500, Chevrolet Silverado 2500 HD, Chevrolet Tahoe, or Chevrolet Suburban that is powered by a Duramax 6.6 liter turbo diesel engine. As GM has periodically redesigned its civilian trucks and SUVs from 2001 to the present, LSSVs have also been updated cosmetically.
The militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook, tow shackles and a 24/12 volt electrical system. The dashboard has additional controls and dataplates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories. In the Canadian Army these vehicles are nicknamed "Milverado".
The Enhanced Mobility Package (EMP) option adds an uprated suspension, 4-wheel anti-lock brakes, a locking rear differential, beadlock tires, a tire pressure monitoring system and other upgrades. About 2,000 LSSV units have been sold to U.S. and international military and law enforcement organizations.
