BMW's highly acclaimed 3 Series receives new engines across the board. The six-cylinder models drop the 325 designation for 328, thanks to a new 2.8-liter inline six. While the new six offers a negligible gain in horsepower (now 190), acceleration is significantly improved by a 14 percent increase in torque (now up to 207). To go along with the heartier engine, 328 models get vented rear disc brakes to minimize brake fade. The 318 models keep the 318 name despite an increase in engine displacement to 1.9 liters, which yields a slight increase in torque. Automatic climate control is standard across the line, except in the 318ti, and upgraded sound systems are optional on all models.
