A seven-speed double clutch transmission (DCT) for enhanced performance and economy is now available as an option for the BMW 3 Series Coupé and Convertible in Europe. The new gearbox, which applies similar technology to that used in an M3 equipped with M DCT (earlier post), is now offered on the 335i Coupé and Convertible models.
The DCT improves performance and economy by splitting the gearbox into the two assemblies, each with its own clutch—as the revs build or decrease in the current gear another one is already selected. A near seamless transition in gears and power is thus achieved benefitting both acceleration and consumption.
News of the new gearbox comes as the new six-cylinder 2,993cc diesel engine announced for the new 3 Series Saloon and Touring models is offered in the Coupé range. Now the BMW 330d Coupé is powered by a 245 hp (183 kW) powerplant, 14 hp more than the previous engine, and 520 Nm (384 lb-ft) of torque, 20 Nm more than before. The upgrade in performance means the 330d Coupé achieves zero to 62 mph in 6.0 seconds compared to 6.6 seconds previously, while also being capable of 5.7 L/100km (41.3 mpg US) on the combined cycle (vs. 6.1 L/100km) and emissions of 152 g/km (vs. 160 g/km).
