At the rear is a five-link coil-spring suspension design, which enables optimal ride
and handling through more precise tuning. Lateral stiffness was increased at the
frame-side joint of the lateral link with the addition of a cross-axis ball joint, for a
greater feeling of steering precision.
Additional chassis and suspension features include:
•
A wider rear track that contributes to a more planted stance
•
Stronger body structure with more high-strength steel for a more solid feel
and a quieter cabin
•
Shear-style body mounts, which reduce body shake and enhance the feeling
of structural stiffness, improve damping performance when compared with
previous compression mounts
•
Third-generation magnetic ride control on LTZ models. Its new, dual-electric-
coil design enabled engineers to tune with more resolution to handle quickly
changing road conditions
•
Eighteen-inch standard wheels are a half-inch wider, reducing tire flex for
improved cornering performance. Twenty- and 22-inch wheels are available
•
New, electric variable-assist power steering system enhances fuel economy
and tailors steering assist to vehicle speed
•
New four-wheel-disc brake system with Duralife™ brake rotors that offer up
to double the service life
•
Revisions that improve pedal feel for more-confident braking performance
•
Available automatic locking rear differential that provides greater traction
when needed and greater driving comfort when it’s not
•
Maximum trailering rating of 8,600 pounds (2WD models).
More powerful and more efficient
Tahoe’s new new EcoTec3 5.3L V-8 engine is rated at 355 horsepower (265 kW)
and 383 lb-ft of torque (519 Nm), and features state-of-the-art technologies
including direct injection, cylinder deactivation, continuously variable valve timing
and an advanced combustion system – all designed to make the most of power,
torque and efficiency across a broad range of operating conditions.
The technologies contribute to EPA-estimated 16 mpg in the city and 23 mpg on the
highway (2WD) – a nearly 10-percent increase in highway mileage over the
previous models and 7-percent greater city mileage. Improved engine mounts,
electronic throttle control, adaptive exhaust systems, improved aerodynamics and
other technologies help the engines operate in four-cylinder mode longer with
Active Fuel Management, contributing further to efficiency.
A Hydra-Matic 6L80 six-speed automatic transmission is paired with the new 5.3L
engine and contributes to efficiency with reduced engine speed on the highway. It
also features TapShift control, tow/haul mode and auto grade braking.
