Unveiled: 2015 BMW M3 and M4 Show Off High-Performance Goods

With the redesigned BMW 3 Series and all-new 4 Series coupe already on the streets, you knew the M3 and M4 were on there way. Prior to their impending debut at the Detroit Auto Show in January, someone, somewhere managed to leak these two out on the web. But we're not complaining. The M3 sedan  (looking handsome in a sultry blue) and the M4 Coupe (in an Austin Yellow Metallic) look the part of the performance machines we've been waiting for. But what more does this duo bring to the table than the cars they replace? For one, under the hood we're met with a twin-turbocharged six-cylinder engine with 430 horsepower on tap. That's ten more horsepower out of a unit that's smaller and more efficient than the outgoing 4.0-liter V8.

Other features will include loads of M performance parts both inside and out (of course), a head-up display, and 19-inch wheels. And it wouldn't be a true BMW without features like heated and power seats, parking assist, and LED lighting. Because, luxury.
