2007 Chevrolet Tahoe Redesigned

Best-selling full-size SUV since 2001

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.
