AVALANCHE: The stereo gets a USB port, and 4x4 models get a single-speed transfer case; last year's low-range transfer case is now an extra-cost option.

Chevrolet re-introduced its classic sports car for 2010, with a strong emphasis on bang-for-buck: The base-model Camaro offers a 300 horsepower direct-fuel-injected 3.6 liter V6 for around $23,000, while the Camaro SS comes with a Corvette-sourced 6.2 liter 426 horsepower V8 for $31,000.CORVETTE ZR1: A new Performance Traction Management (PTM) system provides launch control; when the driver floors the accelerator and dumps the clutch, it modulates the engine's torque output for fast, consistent starts. PTM also manages engine power when the driver floors the accelerator when exiting a corner. Like lesser Corvettes, the ZR1 gets standard side airbags and available Torch Red paint, as well as optional Competition Gray wheels.
