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. |

Let's hope they don't make the 335i a double-clutch auto only!

I still have doubts as to whether or not we will see this engine in any 3er before F30 drops. My guess right now is no.

I grew up in Germany, drove stick shifts all my life, recently a few auto's, but I would take a DCT over a 6-Speed without a second of hesitation. To all DCT haters: Drive it, then judge it!
And btw: 6-speeds are getting less and less because they cannot keep up with the tourque and use more fuel in EPA cycles to my information. Another note: the 335is is confirmed and coming in March.

You are correct regarding the fuel consumption, because of the 7th gear, it drops the emission norm. The future is unclear though. BMW developed a fantastic 8 gear automatic which was said to be the successor of the DCT as well. Recent articles however showed that DCT will stay, but only in M-cars... the future will tell |

And, like someone else pointed out, clutchless (pedal) transmissons improve fuel economy in part because they have a taller 7th gear. Porsche is strongly rumored to be releasing an optional 7 speed manual on their MY2012 991/911. (This will likely be debuted at the IAA, Sept 2011.) |

I am sorry but the 7 speed DCT is no good, and i drove it, and my friend has an M3 with it and the manual is just better, the dct is good for older people or someone that cant drive stick... Who goes out and gets an M3 and in auto anyway? Its like going to get a Z06 auto The only time i would get an auto is on a 1200+ hp drag car with a 3 speed powerglide
