The BMW 335i Coupe smartly blends luxury and sport; it's as content zooming along a winding country road as it is motoring along the bleakest of freeways during those endless road trips. Part of its flexibility can be attributed to BMW's much-lauded twin-turbo straight six under hood. It's an engine that's not long for this world, as a more fuel-efficient, single-turbo version is in the offing from Munich. We'll miss the twin-turbo's stout powerband and overall tractability. It's deceivingly smooth -- you'll find yourself climbing well above posted speed limits if you don't pay attention. It's docile at low rpm, but surges through the tach with immediacy at a squeeze of the throttle. The EPA rates the two-door 335i at 17/26 mpg.
