The most significant change is of course the adoption of General Motor’s latest 3.6-liter V6 engine with direct-injection technology and E85 Flex-fuel capability, linked to a standard six-speed automatic transmission. The preliminary spec-sheet does not refer to performance numbers, but it has been reported that the V6 should be good for around 302-horsepower.
The mechanical updates are complemented by some minor styling changes up front, namely the new mesh grille and fog light surrounds, and at the rear, along with a new set of 16-inch alloy wheels and changes to the available equipment packages.
With the 2012 model year update, GM hopes to keep interest up on the Impala as a brand new replacement isn’t due for another two to three years.
