2012 Chevrolet Tahoe

Chevrolet Tahoe is a full-size SÚV that offers spaciousness and a strong towing capability of up to 8,500 pound (3,855 kg). It also delivers surprising fuel economy, with 2WD models estimated at 21 mpg on the highway.

A fuel-saving Hydra-Matic 6L80 six-speed is standard on all models, which contributes to the Tahoe's highway fuel economy via reduced engine speed. That lower engine speed also helps make the interior quieter.

For even greater fuel economy in a full-size SÚV, customers can select the Tahoe Hybrid. It uses GM's patented two-mode hybrid system to deliver a 33-percent improvement in fuel economy in city driving. Please see the separate Tahoe Hybrid release for complete details.

Chevrolet Tahoe is available in LS, LT, LTZ and Hybrid models, all offered in 2WD and 4WD. Each is built on GM's full-size SÚV platform that features a fully boxed frame, coil-over-shock front suspension and rack-and-pinion steering. Wide front and rear tracks enhance handling and lower the center of gravity for a more confident road feel.

Changes and new features for 2012 include a new hard-drive navigation radio with a ÚSB port, Time Shift Recording capability and more. Also new is a leather-wrapped heated steering wheel and StabiliTrak now incorporates trailer sway control and hill start assist. Three new exterior colors are offered.

Tahoe powertrain

All models are powered by a Vortec 5.3L V-8 that balances power and efficiency. Variable valve timing helps the 5.3L optimize performance, efficiency and emissions, while GM's Active Fuel Management cylinder deactivating technology helps improve fuel economy in certain light-load driving conditions. It is also E85-capable and matched with GM's Hydra-Matic 6L80 six-speed automatic transmission. (posted on conceptcarz.com)
•Vortec 5.3L with an iron cylinder block is used on 2WD and 4WD models (engine code LMG) and rated at 320 horsepower (239 kW) and 335 lb.-ft. of torque (454 Nm).
•The variable valve timing system allows linear delivery of torque, with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement). It also helps reduce exhaust emissions. Because it manages valve overlap at optimum levels, it eliminates the need for an Exhaust Gas Recirculation (EGR) system.
•GM's Active Fuel Management technology increases fuel economy approximately 6 percent under the federal government's required testing procedure and potentially more in certain real-world driving conditions. AFM temporarily deactivates four of the engine's cylinders under light load conditions and seamlessly reactivates them when full power is required. The transition takes less than 20 milliseconds and is virtually indiscernible.
•A heavy-duty timing chain delivers quiet operation and long life. It is validated for 200,000 miles (320,000 km) of operation.
•E85 is a clean-burning, domestically produced alternative fuel comprising 85 percent ethanol alcohol and 15 percent gasoline. Ethanol is renewable and produces fewer greenhouse gases during the combustion process.

Tahoe chassis and suspension

The Tahoe is built on GM's full-size SÚV platform, incorporating a fully boxed frame, coil-over-shock front suspension, leaf-spring rear suspension and rack-and-pinion steering.
•Wide front and rear tracks – 68.2 inches (1,732 mm) front/67 inches (1,702 mm) rear – enhance handling and vehicle stability for a more confident road feel.
•A stiff frame reduces vibrations transmitted to the passenger cabin, while the strength and accuracy of the fully boxed frame also enable precise mounting and tuning of chassis and suspension components.
•The Autoride suspension system is standard on LTZ and features a segment-exclusive bi-state, real-time damping system that provides a 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.
•A single-speed transfer case is standard on LS and LT 4WD models.
•A two-speed transfer case is standard on LTZ 4WD and available on LS and LT 4WD models.
•A trailering package with a 3.42 axle ratio, external transmission cooler and engine oil cooler is available on LS, LT and LTZ models.
•The standard axle ratio on all models is 3.08.
•A locking rear differential is standard on LT and LTZ models and available on LS.

Tahoe safety and crash-avoidance features
•Standard head curtain side air bags with rollover protection for both seating rows. The roof-mounted head curtain air bags include design features that provide increased rollover protection and occupant containment.
•Standard seat-mounted side-impact air bags for driver and right-front passenger provide thorax and pelvic protection.
•StabiliTrak electronic stability control system helps reduce the risk of rollover crashes by keeping the vehicle in the driver's intended path by applying throttle, braking or a combination of both.
•Available Últrasonic Rear Parking Assist that can detect certain stationary objects in the rearward path of the vehicle and send an audible warning sound and display via three LEDs near the rear window
•Available rearview camera system designed to provide the driver with
a view of people or objects in the rearward path of the vehicle.
•Side blind zone alert is standard on LTZ.
•Standard four-wheel-disc brake system with ABS featuring smooth, quiet operation, longer pad life and more resistance to brake pulsation.
•Pretensioners minimize forward movement during a collision, and are standard on the front safety belts. Load-limiting retractors cinch the belt more tightly.
•LATCH (Lower Anchors and Tethers for CHildren) child seat attachment system, which is included in two of the second-row seating positions.
•Tire pressure monitoring system, standard on all models.
•Standard remote keyless entry (RKE) system provides a second function for the red panic button. Drivers can use it to locate their cars without sounding the panic alarm.
•Strong body structure to absorb crash energy and provide a protective 'safety cage' around occupants.

OnStar details

OnStar is standard on all Tahoe models. It uses GPS and cellular phone technology to automatically call for help in the event of crash. OnStar subscribers also can use the service to be Good Samaritans by sending help to other motorists, and to call for help in other non-crash emergencies.
•OnStar is the leading provider of in-vehicle safety, security and information services in the Únited States and Canada.
•Six months of complimentary OnStar Directions and Connections service with Turn-by-Turn Navigation for easier route guidance on all Tahoe models. The feature is easy to use because all directions are sent to the car by an advisor, without the need to stop. Turn-by-Turn can be cost-effective, since map updates and aftermarket navigation systems are not needed.
•Stolen Vehicle Assistance helps police track the vehicle.
