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. We averaged 25.3 mpg hwy/hooligan combined.
Lag is a non-issue. In fact, the 335i accelerates as though it has a large displacement engine, not a turbocharged one. Peak torque, 300 lb-ft, is on tap from 1400-5000 rpm. And the claimed 300 hp leads us to believe BMW is being bashful: The last 335i manual we tested reached 60 mph in 5.1 seconds.
