"... Equipped with BMW's new twinpower twin-scroll turbo 2.0-liter 4-cylinder N20 engine, BMW specifies its power rating in North America at 240 bhp (179 kW / 243 PS) and 260 lb-ft (350 Nm).
Using an EAS (European Auto Source) Dynojet 224xLC, the 328i produced 226 hp (169 kW) and 230 lb-ft (312 Nm) torque measured at the wheels with 91 octane gasoline. This equates to a crankshaft horsepower rating of approximately 265-272 hp (198-203 kW) / 270-277 lb-ft (366-376 Nm) torque - an increase of 25-32hp (19-24 kW) and 15-22lb-ft (20-30) over the official figures. This calculation assumes a 15-17% drivetrain loss."
