Introduction The Chevrolet Impala is a big, roomy sedan. While classified as a midsize sedan, it's large for that class. Close in size to the Toyota Avalon, competes with mid-size and full-size cars. Among them: the Ford Taurus, Chrysler 300, Dodge Charger, as well as the Honda Accord, Toyota Camry, and Nissan Altima. We find the Impala's neat, clean lines pleasing to the eye. Its styling looks fresh, and it is, having been sharpened when the Impala was last redesigned for 2006. Other people think so: the Impala is among the top-10 best-selling cars in the U.S. This is a roomy car, in the front as well as the back seats, and getting in and out is easy. The Impala has a big trunk with a big trunk lid that makes loading cargo easy, and it has a healthy cargo capacity. Optional flip-and-fold rear seats are exclusive in its class, and provide not only holding wells for groceries but a flat cargo floor that expands the trunk for long items. On the road, the Impala is very stable, a nice cruiser. There's lots of low-end torque from the larger of the two available V6 engines, a 3.9-liter V6 with advanced technologies. Step on the gas and it goes. Given its size, the Impala handles well, and surprisingly so. Several models are available, ranging from strong, reliable, fuel-efficient family sedan to sleek and powerful performance car. The mid-level Impala LT probably best exemplifies the model line. We like the LT with the optional 3.9-liter V6, which features GM's Active Fuel Management to improve real-world fuel economy.
