Car and Driver upgraded 335i engine
More Power From the Turbo Six, Not That it Needed Any
Tuners have proven it time and again: the twin-turbo BMW inline-six is capable of more than the factory-provided 300 hp and 300 lb-ft of torque. BMW is now ready to admit as much, apparently, and has given the engine better intake breathing and higher boost pressure for new output of 335 hp at 5900 rpm and 332 lb-ft from 1500 rpm, with overboost providing quick bursts of 369 lb-ft. A specifically tuned exhaust system is promised to provide a “deep rumble with a focus on the low-frequency sound range.”
Transmission options number one; the sDrive35is will be available only with BMW’s seven-speed double-clutch transmission. Here, it features a dual-mass flywheel to handle the increased power. The programming is also unique to the model. Gear changes can be effected either via the console selector or wheel-mounted paddles. Launch control is part of the package, as well.
