430 hp and 369 lb-ft of torque will be propelling BMW’s new 3,300 pound M cars

The in-line six is coming back to the M-badged 3-series lineup, though this time it will be attached to two turbos to produce performance above that of the outgoing 4.0L V8.

The new 3.0L TwinPower Turbo in-line six will be good for approximately 430 hp and 369 lb-ft of torque when it goes on sale next year. But, the new engine isn’t the only news coming out of Munich.

Extensive use of carbon composites will be featured on the new M3 and M4, including a carbon fiber roof for the sedan, traditionally only available on the coupe. This has brought weight of the new M cars down nearly 200 lbs.

BMW has released tons of graphics (in German) outlining the new M cars, which can be seen below.
