BMW M2 Competition
The BMW M2 Competition was introduced at the 2018 Beijing Auto Show and replaced the standard M2 Coupé as a more powerful variant.[12] Production began first in July 2018, delivered early 2019.[13]
The M2 Competition uses the BMW M GmbH S55 engine, a high-performance variant of the N55 engine, that has been detuned from its application in the F80 M3 and F82 M4. The decision to use the S55 engine was a result of Europe adopting the Worldwide Harmonised Light Vehicles Test Procedure as the official procedure to measure vehicle pollutants, which meant that the standard M2's N55 engine was no longer conformed to European emission standards.[14] Differences from the N55 engine found in the standard M2, the S55 includes a closed-deck engine block, lightweight crankshaft, different crankshaft bearings, strengthened pistons and connecting rods, different springs/valve material, twin turbos, twin fuel pumps, active exhaust, revised cooling system and intercoolers. The engine also features a redesigned oil supply system, modified cooling system, and electronic locking differential parts that are adapted from the BMW M4 Competition Package. It also features a gasoline particulate filter in certain European Union countries to reduce emissions.[15] Compared to the standard M2, the S55 produces an additional 30 kW and 85 Nm, resulting in a larger and more sustained power output of 302 kW between 5,250 and 7,000 rpm, and 550 Nm at 2,350–5,200 rpm.[16][17][18] The 0–100 km/h acceleration time is 4.4 seconds for 6-speed manual transmission models, and 4.2 seconds for models with the 7-speed dual clutch transmission.[19] Top speed is electronically limited to 250 kph, but the M Driver's package can extend the limit to 280 kph which is 10 kph higher than in the M2 Performance Edition.[20]
The M2 Competition has the standard carbon-fibre reinforced plastic strut bar found in all S55 engine equipped models, to lighten and stiffen the car, enlarged kidney grilles, and optional larger brake discs of 400 mm in the front axle with 6-piston calipers and 380 mm in the rear axle with 4-piston calipers.[9] Because of the engine and cooling system borrowed from the F82 M4, the M2 Competition is 75 kg heavier than the standard M2 which had 1550 kg for manual transmission models and 1575 kg for dual-clutch transmission models.[21]
