The official film for the BMW M3 and M4 has made it over to the states via social media shortly after the “leaked” photos surfaced. Just yesterday, the details of the all-new F82 M4 and F80 M3 were leaked out and the news spread like wild fire. The unofficial announcement sparked a similar reaction in the social media world just as when the F82 M4 concept was revealed at the Pebble Beach Automotive Week in Monterey, CA.

Surprisingly, the production version was not that different than the concept.

When the 2008 E92 and E90 M3 models came out, it was rather unpleasing to hear the BMW M models moving away from the small platform and engine efficiency business model which made the M line so iconic. When the first E30 M was launched, this was the idea, that it wasn’t all about the horsepower, but a balance between the engine output and engineering efficiency. In 2001, the S54 engine that came in the E46 M3 had one of the highest horsepower per liter for a production car. Now days, BMW is creating heavier and bigger cars to keep up with the current automotive industry, packing in large displacement V8 engines to get more power while sacrificing the attributes that come with a smaller, more balanced platform. However with the new F82 and F80 M models, it seems like BMW took one step back from this “American muscle” direction.

The all-new 3.0 liter BMW M3 and M4 engine is now a turbocharged inline-six engine opposed to it’s V8 predecessor. The engine creates 425 horsepower with 406 lb-ft of torque and is capable of going from 0 to 60 mph in 3.9 seconds with the M-DCT transmission. Not only is the motor lighter now, but the car is also said to be 200 pounds lighter than E9x predecessor. The all-new BMW M3 Sedan and BMW M4 Coupe will debut at the 2014 North American International Auto Show in Detroit. The 2015 M3 and M4 will begin showing up at US dealerships beginning Summer 2014.
