2011 BMW 3-Series Coupe and Convertible

Moving the 335is on its standard 18-inch alloy wheels is the newly updated N54 twin-turbo straight-six engine and a seven-speed DCT dual-clutch transmission. Early reports show the power at 322 horsepower, but the engine-sharing Z4 sDrive35is is rated at 335 hp. The folks at Motor Authority suggested the discrepancy may be explained by the fact that the numbers for the 335is are coming from leaked Canadian documents – which may require slightly different tuning for emissions.
