REDESIGNED 2007 CHEVY TAHOE IS THE BEST YET

DETROIT – Chevrolet has announced the debut of the 2007 Chevy Tahoe, the next generation of the industry’s best-selling full-size SUV. The new Tahoe is comprehensively redesigned and delivers a sharper, more precise driving feel, more power with improved, segment-leading fuel economy, increased interior refinement and improved quietness.

The new Tahoe takes over at the top of the segment in sales, quality and comfort – Tahoe has been the best-selling full-size SUV since 2001. The outgoing model (along with its longer sibling, Suburban) has ranked first in the J.D. Power and Associates Initial Quality Survey for five years, topping all import and luxury models. Engineers built on Tahoe’s established credentials with a “no compromises” mantra that realized improvements in many areas of performance, quality and comfort.

Contributors to the 2007 Tahoe’s segment-leading capability include:

Superior ride, handling and quietness
Improved efficiency
Refined interior with thoughtful convenience built in
Distinctive, sporty exterior design
Enhanced safety and security
“Tahoe is known for delivering whatever its customers want, whenever they want to do it – a hard-earned reputation reflected in countless independent quality studies, buying guide recommendations and customers who have returned to buy another vehicle,” said Ed Peper, Chevrolet general manager. “The ’07 model enhances the attributes that have made Tahoe the industry’s best-selling full-size SUV and improves them with dramatically increased attention to detail in smoothness, quietness and refinement. We believe it is simply the best Tahoe yet.”

Superior ride, handling and quietness

The 2007 Tahoe is built on GM’s new full-size SUV platform, which incorporates features such as a new, fully boxed frame, coil-over-shock front suspension, rack-and-pinion steering and an all-new, premium interior system that bolster the vehicle’s comfort, quality and capability. Wider front and rear tracks enhance handling and lower the center of gravity for a more confident road feel.

Extensive attention to detail was paid by Tahoe’s engineers to ensure a quiet driving experience. It starts with a new, stiffer frame, which reduces vibrations transmitted to the passenger cabin. The strength and accuracy of the full-boxed frame also enables more precise mounting and tuning of chassis and suspension components, which also helps reduce vibration. Even the tires on the large, 17-inch standard and 20-inch available wheels, were designed to reduce noise.

Noise-reducing components and materials are used throughout the body structure, including the headliner material, door seals and front-of-dash area. The engine also features a quiet-tuned alternator and an acoustically tuned engine cover that dramatically reduces engine noise heard inside the vehicle. New door seals help reduce seal “pull away” at highway speeds, which can cause wind noise. Also, Tahoe’s more slippery shape, thanks to improved aerodynamics, streamlined exterior mirrors and roof rack, and tighter body gap tolerances, makes Tahoe quieter as it slices through the air.

Tahoe also features details such as spray-in expanding foam, which helps reduce noise by filling in space to eliminate sound paths. The foam, located mostly in the A-pillars, expands to fill the void of a space. Tahoe’s quietness and smoothness is complemented by the Autoride suspension system, which is standard on LTZ. This segment-exclusive bi-state, real-time damping system provides an extremely refined ride with greatly reduced body motion. The system consists of a semi-active, two-position damping control system that responds in real time to road and driving conditions, based on body and wheel motion sensors.

Tahoe’s quietness and smoothness are complemented by capabilities full-size SUV customers depend on. Tahoe offers up to 7,700-pounds (3,492 kg) towing capability (4WD models).

Improved efficiency

A new Gen IV small-block V-8 family – the newest chapter in the small-block’s 50-year history – offers more power than comparable powertrains in previous models. Fuel-saving Displacement On Demand technology also enables better fuel economy. When combined with other vehicle-wide features, including improved aerodynamics, the small-block V-8 helps give the Tahoe the segment’s best fuel economy. Preliminary testing with 5.3L-equipped models shows unadjusted combined fuel economy ratings of 20.5 mpg with 2WD models and 20.1 mpg with 4WD models. That’s better fuel economy than any other full-size SUV.

New engine choices allow consumers to choose the performance level that meets their needs. A Vortec 5.3L V-8 with 320 horsepower (238 kw)* and 335 lb.-ft. of torque (463 Nm)* offers fuel-saving Displacement On Demand technology is standard at start of production. A Vortec 4.8L V-8 becomes available later and will be standard on Tahoe 2WD models.

A more steeply raked windshield and smoother roofline improve the aerodynamics of Tahoe, resulting in a best-in-class 0.363 cd, which enhances fuel economy on the highway. Additional contributors to efficiency include a lower, wider front air dam, tighter tolerances and gaps between the fascias, lamps and grille openings, and improved front-end sealing that nearly eliminates air leak paths. These features all contribute to enhanced fuel economy and improved driving quietness, compared with previous models.

“The economy of the new Tahoe is tremendous,” said Gary White, General Motors North America Vice President and vehicle line executive for full-size trucks. “It not only delivers better fuel economy than some smaller vehicles, it does so with the full capability expected of a full-size SUV. That means you can tow a boat out to your favorite lake on the weekend and take the kids to school during the week without worry – it’s another trait of Tahoe’s do-anything personality.”

Refined interior and thoughtful convenience built in



The ’07 Tahoe is available in three trim levels: LS, LT and LTZ, with the high-volume LT trim level offered with LT-1, LT-2 and LT-3 equipment groups. Two-wheel drive and four-wheel drive models are available. All models come well equipped with enhanced safety, comfort and convenience features. New and substantially revised features include:



Power-release fold-and-tumble second-row seat

Remote vehicle starting system

First- and second-row heated seats

Ultrasonic Rear Parking Assist

Rearview camera system

Touch-screen navigation system

Power-articulating running boards (mid-year availability)

DVD rear-seat entertainment system with larger, 8-inch screen and enhanced features

Refinements throughout Tahoe’s spacious interior create an environment that exudes quality and precision, as well as comfort. A two-tone color scheme is executed with new, softer and low-gloss materials for the instrument panel and other trim pieces. Additional details include LED backlighting for the instruments and chrome accents on instruments and vents. Flush-mounted accessories and controls, such as the climate control/radio center stack create a seamless, “single unit” appearance. Also, there are almost no exposed metal hardware or latches, as all models feature enclosing “close outs” around the seat bottoms and door sill trim plates.



Distinctive, sporty exterior design



The amenities and performance features are wrapped in a stylish new package that conveys the sporty, ready-for-anything reputation of Tahoe. An all-new exterior design is leaner and more agile looking, with large wheels and the wider track enhancing Tahoe’s powerful, capable stance. The improved aerodynamics also contributes to the sleek look, with a more steeply raked windshield and smoother roofline accentuating the exterior length.



Tahoe is the first truck to feature the new face of Chevrolet with a large Chevy gold bow tie, centered on a twin-port horizontal grille. The body-colored grille surround is inset with an argent texture mesh. Fog lamps and headlamps feature jewel-like optics. The lower fascia, incorporating the front license plate holder and integrated tow hooks, is aggressively styled with a skid plate look that enhances Tahoe’s rugged, off-road appearance.



Tahoe’s front end reflects its sporty, outdoor character. It includes the fast-rake windshield; a bulging power dome hood; a prominent new fender design, with integrated wheel flares; a distinctive new grille and headlamps; and a full-wrap fascia. The wraparound fascia, which eliminates the conventional bumper-to-body gap, is one of the numerous attributes that gives the Tahoe a more refined look. It also enhances aerodynamics.



Also complementing Tahoe’s sporty appearance is a new family of 17-inch and 20-inch wheels. Seventeen-inch wheels and tires are standard, with 20-inch factory-installed wheels available. The larger wheels fill Tahoe’s wheel houses, giving the vehicle a confident stance.



The available Z71 package (available later in 2006) takes this aggressive look to the next level. It includes a specifically designed three-piece fascia with a protective, platinum chrome skid plate. It has larger tow hook openings; larger, more prominent fog lamps; and specific grille texture and platinum chrome grille trim. Eighteen-inch wheels and tires also are part of the package.



Tahoe is offered in nine exterior colors: Greystone Metallic, Dark Blue Metallic, Sport Red Metallic, Bermuda Blue Metallic, Black, Summit White, Gold Mist Metallic, Antique Bronze Metallic and Silver Birch Metallic.



Enhanced safety and security



The 2007 Tahoe has a comprehensive package of standard and available safety features. New features, including roof-mounted head curtain side air bags with rollover protection for all seating rows, complement the stronger chassis and body structures to provide excellent passenger protection.



For further protection, the StabiliTrak electronic stability control system with new roll-over mitigation technology is standard on all models. With the enhanced StabiliTrak system, sensors continuously monitor the vehicle’s side-to-side angle, triggering stability-maintaining action if the angle indicates a possible roll-over condition. If a roll-over is likely, the system can trigger the roof-rail air bags before the incident occurs to provide passengers with increased protection.



Crash avoidance also is bolstered through enhanced driver control dynamics, such as wider front and rear tracks, as well as more responsive suspensions – including a new coil-over-strut front suspension design and new rack-and-pinion steering.



Tahoe’s additional safety features include:



Standard dual-stage frontal air bags with GM’s passenger sensing system

Roof-mounted head curtain side air bags with rollover protection for all seating rows available on LS, LT-1 and LT-2 models; standard on LT-3 and LTZ

Standard front seat safety belt pretensioners (with rear-crash activation)

Remote vehicle starting system standard on LT-2, LT-3 and LTZ; prep package for dealer installation standard on LS and LT-1 models (includes keyless entry remote)

Power-adjustable pedals standard on LT-2, LT-3 and LTZ, available on LS and LT-1

Tire pressure monitoring system standard on all models

Daytime running lamps

RainSense automatic windshield wiper activation standard on LTZ and available on LT-3

Heated windshield wiper fluid standard on LTZ and available on LT-3

Standard four-wheel disc brakes with Bosch 8.0 four-channel ABS

Available 4WD with Autotrac automatic transfer case

OnStar with Advanced Automatic Crash Notification

Available technology, including Ultrasonic Rear Parking Assist and a rear-view camera system, enhance safety at all corners, helping – in addition to the numerous crash and roll-over sensors – to give the Tahoe 360 degrees of protection. Ultrasonic Rear Parking Assist is standard on LT-2, LT-3 and LTZ models and available on LS and LT-1. The rearview camera system is available on LT-2, LT-3 and LTZ models (requires navigation radio).



Along with GM’s other new full-size SUVs, Tahoe’s chassis and body structure are designed for improved crash energy management. The front frame section has improved crush dynamics that provide the equivalent of 17.7 inches (450 mm) of additional crush space, when compared with the previous-generation models – in a vehicle that is only approximately 3 inches (76.2 mm) longer. The frame also is designed for improved vehicle-to-vehicle compatibility in the event of a crash with a smaller vehicle.



All Tahoe models are equipped with the OnStar Generation 6 system, including a one-year subscription to the Safe & Sound plan. The system features digital and analog coverage. OnStar is the leading provider of in-vehicle safety, security and information services in the United States and Canada . Using the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Hands Free Calling (OHC) that allows drivers to make and receive hands-free, voice-activated phone calls using a powerful 3-watt digital/analog system and external antenna for greater reception. OHC requires an additional OnStar service contract and pre-paid calling minutes, and is not available in Alaska and some other markets. Calls can be made to U.S. and Canada only.



The OnStar service available on the Tahoe includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in an accident that activates an airbag, the OnStar system automatically notifies an OnStar Adviser who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen (ability to locate stolen vehicles varies with conditions).



The 2007 Tahoe will be built at Arlington Assembly, in Arlington , Texas , and will be available in the first quarter of 2006.



“Chevrolet introduced the SUV with the 1935 Suburban and the new Tahoe is the culmination of more than 70 years of experience building these vehicles,” said Peper. “The 2007 is not only the most refined SUV in the segment, we believe it to be the best SUV we’ve ever built.”



*Preliminary, pending certification. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.

When GM said 20 MPG, I assumed that they meant 20 MPG HIGHWAY. They have really delivered if this really gets a combined mileage in excess of 20 MPG.

They should have 6 spds from the launch. That could add .5 MPG or so. Then another 25 percent increase from the hybrid system, this should definitely take the full-size SUV crown (okay, it already has the crown, it should destroy everything else). Even loyal Ford and Dodge buyers will have to take a second look if Tahoes get 20-26 MPG combined city/highway, while Expeditions and Durangos are getting 15 or 16 MPG combined. Ford and Dodge simply made their SUV's too heavy, a fact that cannot be undone until the next full makeover.

The article says combined of 20.5 mpg. I guess we'll have to wait and see.

Actually, the key is that the article says the combined unadjusted fuel economy is 20.5 for 2WD and 20.1 for 4WD. Unfortunately, the EPA adjusted numbers (which are the window sticker #'s) are reduced by 10% City/ 22% Highway. Then the combined is some ratio (70/30?) between the Hwy/City cycles.

It's Combined Fuel mileage is 20.5MPG for the 2wd and 20.1 for 4wd I believe, but it's definitely COMBINED fuel mileage, pretty cool.

I heard today that it is 20.5 MPG overall with 15MPG city, 25 Highway. Pretty Impressive.

I like all they have done with the new trucks except one thing. Why is the six speed transmission only available with the biggest engine. It needs to be standard across the board. Think of the mileage they could create if the 4.8L V8 with DOD and backed by the six speed. And thats mileage with the trucks and with the Greenies out there that like to complain about mileage. I guess I just dont understand why the six speed is just not standard across the board.

Well, if the combined is as HEV says expect a real adjusted combined of 17-18. Lets hope he is wrong.

I'd give the interior a 9, the exterior an 8, and the powertrain options a 6.

At first I was fairly ticked James's numbers were so far off, but then I remembered that fuel econ will sell these things - not hp. The hp becomes important in the Slade and Denalis - and 400 sounds just fine. Thats up 60 from last year. The 5300 jump is less impressive, but still more than adequate - especially if we get a combined 20.5 - thats incredible (probably too incredible, I'm thinking HEV is right, and expect 15-16/22-23 - still pretty good. DoD is the only fuel saving feature over last year. So, I'm not expecting a huge change in city. Lack of the 6 speeds in anything that costs less than 50 grand is dissapointing.

Ultra Magnus I agree - All engines should have had DoD, VVT, and 6 speeds. That would have been true leadership. I also agree, the 4.8 with DoD and a 6 speed may have gotten another 2-3mpg. Exactly what GM needed.

Towing capacity - if they sacrificed some for a weight and hence fuel econ savings that makes great sense for the Tahoe. The Suburban better have its class leading pulling power.

So, overall I'd give the package an 8, not the 9 or 10 GM really needed. These will be best in class - but with gas prices the way they are - I'm not conviced delaying all those Zeta vehicles was the right call for what we got. Keep in mind my standards are very high, a true "10" would have been a standard hybrid system - something I still think makes sense if it is a $1500 option as claimed by GM and gives back 25-30%

James still has some explaining to do. He was wrong on so many accounts. Still pretty cool. I love the new pics and info.
In about April James came out of nowhere, and made all those claims. Will he now disappear just as quick? :(

"15 city 25 hwy."

I would think the city number will be higher and the highway number lower because of the DOD.
I am guessing 16-17 city and 23-24 highway.

My SRX V6 is rated at 23mpg hwy so the Tahoe has the potential to do even better.
I think your numbers are probably closer. The current 4.8L does 16/20. If they can make the 5.3L get similar mileage in the city with the heavier 2007 (yes, it looks like it's about 300 lbs heavier - boo), and let DoD add 3 onto the highway figure, that should be the increase they are talking about.

If I understand you right, the $13,000 Cobalt should also get the 6 speed atuo! Or did you mean to say that a vehicle that cost nearly 50G`s should have the 6 speed atuo?
