The BMW M5 is one of the greatest sport sedans BMW has ever produced, but they’ve truly upped the ante with their new M5 Pure Metal Silver Edition. With a production run of only 50, this extremely limited edition is going to be hard to get your hands on and for good reason. The special silver, multi-layer paint job, along with the special M 20″ alloy wheels are the first things that jump out, but it’s what’s under the hood that really matters. Thanks to the 4.4L, twin-turbo V8, this four-door outputs 600 horsepower and 516 pound-feet of torque (both of which are more than even an M5 with the Competition Package) when mated to the M dual-clutch transmission. Put all those features together and you’ll be stylishly hitting 60mph in under 4 seconds.
