10th October 2005.
The timing is certainly not the best to
launch a new family of full-size
trucks, SUVs and pickups.
With fuel prices soaring on a global scale, General Motors
new GMT900 family of
trucks couldn't fall on
more delicate circumstances.
That's the half-empty side of the
Pending on future sales results, the
other half-full side of the same story can logically claim
that the need for full-size trucks doesn't depend only on
fuel prices, but on real pragmatic needs for powerful
pickups and SUVs.
Other arguments might add that renewing
a wide selection of models should refresh demand,
especially that the new family promises significantly
better fuel efficiency than the current GMT800 family.
Better fuel efficiency is mainly attributed to the
Displacement On Demand, at least in the beginning, since
Diesel is considered as an additional possibility during
the GMT900 life cycle.
fit & finish, tighter gaps between
panels, higher perceived quality.
If growth expectations can be ruled out
for this segment, at least until cost-realistic hybrid
solutions bring convincing fuel savings in the future
(with adequate full-size truck capabilities), GM's new
full-size trucks family can best hope for market share
growth... at the expense of Ford's
Expedition and the
Japanese brands full-size trucks: Toyota's
Sequoia and Nissan's Armada.
But that's a different story which time will tell in the
not-too-distant future anyway.
Chevy Tahoe - GM started by
announcing the first member of the GMT900 family, the 2007
Chevrolet Tahoe, which will be launched in the first
quarter of 2006, just a few months before the other
members of the GMT900 family, the Suburban,
Avalanche pickup, the GMC Yukon, XL and Denali, the
Cadillac Escalade family and Hummer's H2.
With the new Tahoe, GM is promising a
sharper, more precise driving feel, more power with
improved fuel economy, increased interior refinement and
proportions, better aerodynamics for less
noise and consumption.
The 2007 Tahoe is built in Arlington ,
Texas 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, with wider front / rear tracks and lower center
of gravity to enhance handling and stability.
GM claims that its new, stiffer frame
should reduce vibrations transmitted to the passenger
cabin. 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 cover to reduce
engine noise heard inside the vehicle.
attention to interior quality:
trucks are no more just...trucks.
Tahoe’s improved aerodynamics,
streamlined exterior mirrors and roof rack, and tighter
body gap tolerances should add to its quietness. A more
steeply raked windshield and smoother roofline improve the
aerodynamics 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 to reduce air leak paths.
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. It consists of a semi-active,
two-position damping control system that responds in real
time to road and driving conditions, base on body and
wheel motion sensors.

Engines - A new generation (gen.
IV) small-block V-8 family – the newest version of the
small-block’s 50-year history – offers fuel-saving
Displacement On Demand technology for better 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 (engines figures
The Gen IV small-block Vortec V-8 engine family is
standard in all Tahoe models, with the 5.3L version
standard at start of production. It is rated at
(preliminary figures) 320 horsepower (238 kw) and 340
lb.-ft. of torque (470 Nm), an 8 percent horsepower
increase compared to the previous 5.3L engine.
A Flex-Fuel E85 version, which is capable of running on
E85 ethanol fuel or a mixture of E85 and gasoline, is
standard on 4WD models and available on 2WD models. E85 is
comprised of 85 percent ethanol, which is a renewable
resource fuel produced in the United States .
and side curtains.
A 4.8L V-8 engine, rated at 290 horsepower (216 kw)
will be standard on Tahoe 2WD models later in the ’06
model year. All new Vortec engines represent the fourth
generation of the small-block V-8, which debuted in 1955.
Highlights include revised cylinder block design,
Displacement On Demand on 5.3L engine, electronic throttle
control, and a new, more powerful engine management E38
GM claims the 5.3L engines with Displacement On Demand
(DOD) technology (available at the Chrysler
group as well) provide up to seven percent increased fuel
efficiency when measured against a comparable non-DOD 5.3L
engine. DOD can temporarily shut down the combustion
process of half the engine’s cylinders under certain
driving conditions to save fuel.
An engine controller determines when to deactivate
cylinders, allowing the engine to maintain vehicle speed
in lighter-load conditions such as highway cruising. The
process is seamless and virtually imperceptible. When the
cylinders are deactivated the engine effectively operates
as a V-4. The engine returns to V-8 mode the instant the
controller determines the vehicle speed or load requires
additional power. The key to DOD’s efficiency and
virtually imperceptible operation is a set of special
two-stage hydraulic valve lifters, which allows the
lifters of deactivated cylinders to operate without
actuating the valves.
seating and loading possibilities.
The ’07 Tahoe will be available in
two-wheel drive and four-wheel drive models, with 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.
The 4WD models offer up to 7,700-pounds (3,492 kg) towing
capability, compared to up to 7,200 pounds (3,266 kg) for
the 2WD ones.
Transmission - Tahoe’s 5.3L and 4.8L
powertrains are teamed with the Hydra-Matic 4L60-E
electronically controlled four-speed automatic
transmission, with an enhanced rear axle system that
supports the increased power and capabilities of the Gen
IV powertrains. They are mounted to the chassis with
stiffer brackets and special bushings that help reduce
noise and vibration
A limited-slip axle is optionally available, as is a
locking differential. Axle ratios range from 3.23:1 to
4.10:1. A new, low rolling-resistance/low-friction pinion
bearing design is used to help reduce driveline friction
and enhance fuel efficiency. The rear axle carrier has
thicker, stronger tubes and the rear cover pan is
50-percent thicker than previous designs.
Interior - 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
The front-row seats have one-inch more
fore/aft travel than previous models. Second-row seats
provide 0.4 inch (10 mm) more legroom and knee room. Their
seatback angle is adjusted an additional two degrees
rearward for extra comfort. Second-row heated seats are
New configurations allow two or
three-passenger carrying capability in all three rows,
including 40/20/40 split-bench with six-way
power-adjustable driver seat (standard on LS models),
60/40-split three-passenger second-row seat (standard on
LS and LT-1).
The second-row seats offer a
power-release fold-and-tumble feature. Simply pushing an
overhead console button or a rear-door pillar button
automatically un-latches the seat(s) and sends it into its
folded and tumbled position. Optional third-row seats can
be removed using two levers on the back of the seat and
stored with wheels at the front of the seat.
Exterior - 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. Tahoe’s front end 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 eliminates the conventional
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
The optional Z71 package (available
later in 2006) 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.
Safety - The 2007 Tahoe safety
features include 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.

Ultrasonic Rear Parking Assist is standard on LT-2, LT-3
and LTZ models and optional on LS and LT-1. The rearview
camera system is available on LT-2, LT-3 and LTZ models
(requires navigation radio).
All Tahoe models are equipped with the
OnStar (US and Canada) Generation 6 system, including a
one-year subscription to the Safe & Sound plan. The
system features digital and analog coverage. 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 (not available in
Alaska and some other markets).
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
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).
