Pros
The 2008 Chevy Impala fends of its competition by offering a big, solid car that delivers smooth and safe performance at a low price.

Model Highlights
The Impala, Chevy's top-seller for the last few years, is usually classed as a mid-size sedan, but it is one of the bigger mid-sizes around. As such, it is no surprise that the Impala boasts roomy seating and almost 19 cubic feet of trunk space. The 2008 Impala comes in four trim levels: LS, LT, LTZ, and SS. The LS and LT have a 3.5L flex-fuel-capable V6, the LTZ comes with a larger 3.9L V6 (with Active Fuel Management), and the SS has a 303-horsepower 5.3L V8. The V6 engines have variable valve timing, while the V8 is mated to a heavy-duty Hydra-Matic four-speed automatic transmission plus performance-tuned four-wheel independent suspension. Beyond that, most of the differences between trims are in small tweaks, such as fog lights, aluminum wheels (both standard with the 3.9L and 5.3L engines) or heated mirrors (standard on the LTZ). As with most mid-size sedans, air bags, power windows, power locks, and air conditioning are standard across the line. In addition, Chevy includes one year of OnStar's Safe and Sound plan. ABS, StabiliTrak, and a tire pressure monitor system round out the standard safety features.

Model News
For 2008, StabiliTrak is now standard on the uplevel Chevy Impala models. The 2LT trim adds 17-inch alloy wheels, while the SS now has 18-inch chromed aluminum wheels and the LTZ has 18-inch machined aluminum flangless wheels as standard. In addition, performance suspension comes with the LTZ trim. E85 flex-fuel ability is now standard with the 3.9L engine. All Chevy Impalas include XM satellite radio. Three new exterior colors join the 2008 palette-Gold Mist Metallic, Mocha Bronze Metallic, and Slate Metallic.
