2012 BMW Z4 sDrive35i
James Bond once drove a BMW roadster with a four-cylinder engine, apparently content with the firepower provided by the Stinger missiles behind the car's headlights. Non-spy buyers were a different story, however, and BMW eventually did away with the Z3's four-banger in favor of a traditional straight-6. That was more than a decade ago, and now an inline-4 engine has returned to a two-passenger BMW convertible, this time as the base engine in the 2012 BMW Z4.
Some people might not like the idea of buying a sports car with a four-cylinder engine. Most won't like the sound of the 2012 BMW Z4 sDrive28i's four-cylinder at idle, as it produces an unbecoming rough clatter. But slot the manual transmission's slick shifter into 1st and lay into the throttle and we're pretty sure you won't have anything to complain about. This torque-rich engine pulls hard and has a sharp, warbling exhaust note reminiscent of BMW's past inline-6s. The 28i also handles a bit better than its six-cylinder siblings thanks to its lighter weight. The 35i and 35is are quicker, but truth be told, you'll be plenty happy with the 28i.
