With the performance you can only get in a 3 Series, it's no wonder the all-new 320i is making quite an impression at the North American International Auto Show.
An eight-speed automatic transmission is standard, while a six-speed manual is optional. BMW estimates the 320i's gas mileage to be about equal to the 328i's, at 22 mpg city and 34 mpg highway with the six-speed manual or 23/33 for the eight-speed auto.
