2008 Chevrolet Impala LTZ

A slightly sportier version of this front-wheel-drive full-size sedan, the 2008 Chevrolet Impala LTZ boasts a stiffer performance suspension. However, it carries the same 233-hp, 3.9-liter V6 and 4-speed automatic as the LT trims. This powertrain gets 240 ft-lbs of torque at 4,000 RPM and around 18/28 mpg, though active cylinder deactivation improves fuel economy somewhat. This engine is E85 compatible. Other sporty upgrades include a rear spoiler, larger 18-inch alloy wheels with all-season tires, leather upholstery, and heated seats and mirrors. Both front seats are now power-adjustable, with the driver's seat moving up to 8-way, and a front passenger getting a 6-way seat. The LTZ features a better 8-speaker Bose sound system as well.

Already standard on the 2008 Impala LTZ are a full power setup, which includes remote entry and remote start, a garage opener, and wheel-mounted cruise and audio controls. A CD player comes with an MP3 input jack and six months of satellite radio. On the dash sit a trip computer, tachometer, temperature display and compass, and wood trim. Leather covers the steering wheel and shifter. Intermittent wipers, two front power outlets, a standard cargo net, dual-zone climate control, and tilt steering are also standard. The sedan seats five in two rows, with a 60/40 split-folding rear seat opening onto a larger 18.6-cubic-foot trunk. Rear legroom is only 37 inches, however. A front split-folding bench is available.

The 2006 Impala LTZ earns four and five stars in crash tests (four in rollover ratings). It comes well-equipped with traction and stability control, 4-wheel disc and ABS brakes, and dual front-side airbags with passenger deactivation and side curtain airbags for both rows. Other safety features include OnStar, automatic halogen headlights, foglights, an auto-dimming rearview mirror, and a tire monitor. There are few options left for the 2008 Impala LTZ, but you can add a power sunroof and shade, a 6-CD changer, and smaller 17-inch alloy wheels.
