BMW has revealed the all-new 6th generation M3 sedan and 2nd generation M4 coupe, two models that make up the heart of the brand's sport-performance DNA.  Powered by the latest version of the 3.0-liter, inline-cylinder, BMW TwinPower Turbo S58 motors producing up to 503 hp, the new M3 Sedan and M4 Coupe also offer the choice of traditional 6-speed manual transmission, something that is rare in the cars’ segment. Four models will be offered at the global market launch next March: the RWD, manual-transmission M3 Sedan and M4 Coupe and the RWD, automatic transmission M3 Competition Sedan and M4 Competition Coupe. Summer 2021 will see the addition of M xDrive for the Competition models.  The new S58 powerplant delivers 473 hp at 6,250 rpm and 406 lb-ft of torque between 2,650 and 6,130 rpm. This allows the M3 Sedan and M4 Coupe to accelerate from 0 to 60 mph in 4.1 seconds on the way to a top speed of 155 mph or 180 mph when the M Driver’s Package is selected. The Competition models’ S58 engine is further tuned to produce 503 hp at 6,250 rpm and 479 lb-ft of torque between 2,750 and 5,500 rpm and reduce 0 to 60 mph acceleration time to 3.8 seconds. Both core and Competition models rev to a redline of 7,200 rpm.  M upgrades over the standard 3 and 4-series models include chassis bracing, brakes, suspension hardware, light alloy wheels with performance tires, and track-ready oil and water cooling systems. MSRP pricing is $69,900 for the M3 Sedan, $72,800 for the M3 Competition Sedan, $71,800 for the M4 Coupe and $74,700 for the M4 Competition Coupe, all with a $995 Destination charge added.
