THE BMW M3 COUPE AND CONVERTIBLE.

Engine30 | 31THE HIGH ART OF M POWER.Speed. Power. Control. Three things on themind of every BMW M engineer. In designingthe M3’s engine, no corners were cut, and noboundaries were set. Their efforts resulted in apowerful 4.0-liter V-8 engine, with a dynamic414-hp output and 295 lb-ft of availabletorque, as well as a maximum engine speedof 8400 rpm. It’s the kind of muscle that willcatapult the M3 Convertible from 0-60 in just5.1 exhilarating seconds. 1 To accommo datethe naturally aspirated engine, the M3 hoodfeatures a contoured powerdome and dualair intakes.Thanks to the M3 engine block’s specialaluminum/silicon-alloy construction, thecylinder surface is created by the exposedhard silicon crystals in the alloy. This eliminatesthe need for conventional coatedcylinder bores. For increased structuralstability, the M3 V-8’s crankcase is milledas a complete forging.To achieve smooth power distributionthrough out the rpm range, the M3’s engineis tuned to truly track-worthy specifications.BMW’s Double-VANOS technology ensurespinpoint-accurate valve timing, which allowsfor optimal combustion at every rev range,while lowering emissions.In keeping with the M3’s racing-inspiredengineering, eight separate throttle but terfliesoperate precisely and independently,delivering amazingly quick throttle response.In addition, the engine’s oil supply is carefullyregulated by an advanced wet sump systemto ensure adequate lubrication under anyconditions. The result: breathtaking accelerationout of the turns and onto thestraightaways.An equally innovative engine managementsystem enhances performance. Ion flowtechnology monitors the V-8’s combustionprocess via the spark plugs, helping toprevent knocking. How far can revolutionaryBMW technology take you?

The M3 engine will automatically shut down when the driveractivates the clutch, switches to neutral and the vehicle is stationary. The engine restartsas soon as the clutch is activated again. This innovation significantly reduces fuel consumption,especially in city traffic. It is also used in conjunction with M DCT with Drivelogic.Eight individually adjustablesingle throttle butterflies allow forinstantaneous engine response.
