BMW M3 E46 3.2 Litre 6-cylinder engine assembly factory – Video

 

The E46 M3, first introduced in October 2000, appeared worldwide with the new 3.2 L S54 M-tuned engine. It was only available in coupe and convertible bodies as the saloon version had been dropped.

The E46 M3 was offered with a standard 6-speed Getrag transmission, but optionally came with a SMG drivelogic transmission (also known as the SMG II). This is the standard 6-speed Getrag transmission with an electrohydraulically actuated clutch (no clutch pedal). Shifts are made via the SMG gear knob or the steering wheel mounted paddle shifters. The engine had a red-line of 8,000 rpm. As with most M engines, the S54 again had 6 independent throttle bodies and this time electronically operated throttles (drive-by-wire throttle with no cable).

In the U.S., the E46 M3 came with similar engine output as the European version, unlike in the E36, whose engine was derived from the M50/52 series engine. Power was now at 333 bhp (248 kW; 338 PS) due to close-coupled catalytic converters closer to the engine exhaust ports. In 2009, Road and Track magazine announced the 2006 M3 with the SMG transmission as its favorite sports car of all time.
