In a rather odd move, General Motors has gone ahead and revealed the police patrol version of the 2012 model year Chevrolet Impala before we get to know the full details on the retail model. The Detroit automaker stated that the 2012 Impala for the public will go on sale this month and will get the additional horsepower and fuel economy of the police derivative.
The highlight of the 2012 Impala redesign in both police and retail forms is the adoption of the GM’s new 3.6-liter V6 engine with direct-injection technology coupled to a six-speed automatic transmission. The six-cylinder unit delivers 302-horsepower and according to GM’s engineering tests, it offers the 2012 Impala a very respectable 0-60mph (96 km/h) sprint time of 6.6 seconds.
