Chrysler and Dodge are offering the 2008 line of minivans – the Town & Country and the Grand Caravan – with three engine choices. They include a 3.3-liter, flex-fuel V6 that’s good for 170 horsepower and works with a four-speed automatic transmission; a 3.8-liter V6 that produces 198 horses and is mated to a six-speed automatic tranny; and a new 4.0-liter V6 that pumps out 240 horsepower and is mated to the six-speed transmission. The all-wheel drive option has been dropped, so all of the new vans put power to the front wheels only, which depending on the trim level, will measure 16 or 17 inches in diameter.
