The Impala practically has nothing new to offer for 2010, except that the SS version has been discontinued. The sedan offers comfort and luxury, but remains affordable. Two V6 engines are available, the first offering a 3.5-litre displacement, while the second offers 3.9 litres, each linked to a four-speed automatic transmission. With its spacious and well-planned interior, the Chevrolet Impala is a safe choice in the mid-size sedan category. It is also much more popular in the United States.
