BMW reduces fuel consumption by 5% on 3-series with dual clutch trans

BMW is launching a refreshed version of its mainstream 3-Series sedan this fall with tweaked front and rear styling. On the mechanical side, we already know about the coming 3.0L dual turbo diesel for the U.S. market. One other change that's coming is the addition of a 7-speed dual clutch transmission. The sports automatic transmissions, as BMW calls them, debuted on the M3 earlier this year and now join the 335i Coupe and Convertible models. The automated shifting of the DCT provides a slight 0.1 second improvement in 0-62 mph acceleration while also providing a five percent reduction in fuel consumption compared to the previous 6-speed automatic. The convertible now has a combined rating of 25.8 mpg (U.S.) while the coupe is up to 26.7 mpg (U.S.). Now, if they would just offer up the DCT with the new diesel, we'd have a killer combination.
