You set a very high standard with everything you do. That applies to the car you drive so you can't help but be impressed by the standard of quality comfort safety and performance represented by the Chevrolet Impala. Authentic V8 power: there's nothing like it. The 5.3L small-block V8 in Impala SS generates a whopping 303 hp. Active Fuel Management shuts down four of eight cylinders in low-demand situations for significantly enhanced fuel efficiency. This fuel-saving technology is also incorporated in the 233 hp 3.9L V6. Impala takes comfort to a higher level thanks to a standard power 8-way driver's seat on SS and LTZ models. A power 6-way driver's seat is standard on LS and LT. Cabin temperature can also be personalized with precision thanks to the dual-zone climate controls that are standard on all but LS models. Peace of mind comes in many different forms. Impala invites you to drive with unparalleled confidence. All Impalas backed by the best coverage in America with our 5 year/100 000 mile Powertrain Limited Warranty.
