Power gains are up to 60hp to the wheels (80hp crank) on a completely stock car on pump gas for a B58 and up to 40hp to the wheels (55hp crank) for a B48, gains with bolt on parts, higher octane, and larger turbos are even higher. The B48 will offer VANOS and Valvetronic just as the N20 currently does. The motor is already in use in 2014 Mini products and the BMW 2-Series Active Tourer will see the engine for the 2015 model year. All BMW 28 models are expected to be upgraded to the 30 designation so for example a 228 would change to 230 for 2015 denoting the new motor.
