The German luxury automaker has officially revealed the 2015 BMW M3 Sedan and M4 Coupe ahead of its public debut at the Detroit Motor Show next month. BMW also released the full specification details of both cars, but they were still mum about the pricing details and release date. But we should be able to predict and guess the release date for the new M3 sedan & M4 coupe.
Both new models are basically using the same engine – a TwinPower Turbo 3.0-liter inline-six engine that can be paired to either a standard six-speed manual or an optional seven-speed M-DCT gearbox featuring Drivelogic and Launch Control. The new six-cylinder engine is capable of spewing up to 431 horsepower with peak torque reaches up to 406 lb-ft.
As a result, the 2015 BMW M3 Sedan and M4 Coupe with a seven-speed M-DCT gearbox can sprint from 0-62 mph in just 4.1 seconds, while models equipped with manual transmission takes at least 4.3 seconds. Unfortunately, the top speed will be electronically limited to 155 mph, but you can also order the optional M driver’s package which increases the car’s top speed up to 174 mph.
BMW claims that the 3.0L TwinPower Turbo engine is 25 percent more fuel efficient compared to the previous generation as well as 80 kg lighter. According to the German automaker, the EPA estimated fuel economy for both cars are rated at 26.7 mpg combined for manual transmission-equipped models and 28.3 mpg combined for the M-DCT version. The CRFP roofs provide benefits in reducing the car weight – sedan model is 5 kg lighter and coupe carries a weight savings of about 6 kg.
The new BMW M3 sedan and M4 coupe will arrive at U.S. dealerships with standard 18-inch alloy wheels wrapped in tires sized 255/40 for the front wheels and 275/40 for the rear. However, BMW still pamper their customers by offering optional 19-inch alloy wheels. Front and rear suspension has been revised by the BMW engineers, where they have tried to use a very lightweight component in the MacPherson strut front and multi-link rear suspension. It’s claimed to increase rigidity and reduce the unsprung mass.
Both cars are equipped with the new BMW M Compound brakes as standard and also available BMW M Carbon ceramic brakes with gold callipers which will be offered as optional. That last one is much lighter than the standard brakes, due to the use of carbon materials. According to BMW, the new M4 coupe will go into production line at BMW’s Munich plant, while the M3 sedan will be manufactured at the Regensburg plant in Germany.
We didn’t find any information about the release date and sale date in the BMW press release. However, we predict that the 2015 BMW M3 Sedan and M4 Coupe should be released in the U.S. market in mid-2014 or most likely by the end of next year. Official pricing details and release date is expected to be revealed at the 2014 Detroit Motor Show, which will be held in January.
