All Tahoe models are built on GM's full-size SUV platform, with a fully boxed frame, coil-over-shock front suspension, and rack-and-pinion steering. At its best, the Tahoe is as responsive as any 5,600-pound vehicle can be and feels much more maneuverable than it should. It's more maneuverable than it might suggest, and it holds the road fairly well, considering it is a tall, heavy vehicle with a solid rear axle.
In Hybrid models, a big 332-horsepower, 6.0-liter V-8 is augmented with electric motors and battery power, using a version of the Two-Mode Hybrid system developed by GM with BMW, Daimler and Chrysler. With this system, the Tahoe can accelerate (lightly) on battery power alone or with a mix of engine and motor power. The hybrid system's batteries and transmission will allow electric-only driving up to 27 mph; beyond that, both the gas engine and electric power are run in parallel, and the gas engine deactivates cylinders to save gas. It's a very fuel-efficient combination, allowing EPA ratings of 20 mpg city, 23 highway, and tow ratings of up to 5,000 pounds.
The Hybrid models have a similar driving feel, though the electric-assisted steering lacks feedback, and regenerative braking makes stops a little less coordinated.
Throughout the standard Tahoe lineup, it can be ordered with rear- or four-wheel drive, with a dual-range system available. The Tahoe Hybrid's system is a more sophisticated, electronically switched system.
