BMW is celebrating driver Marco Wittmann and his recent DTM championship win with a special edition 4 Series. The M4 DTM Champion Edition is basically the second coming of the M4 GTS, which wowed the automotive world last year with its awesome water injection technology. As you'd expect this car is rarer than the one it's based on, with just 200 units set for production; the M4 GTS had a production run of 700 cars. Another thing that sets the M4 DTM Champion Edition apart from the M4 GTS is its price: €148,550 ($163,376).

The M4 GTS was sold for $134,200, with the markup for the new car likely owing to its collectible status. That's the only conclusion we could come to as the two M4s are basically the same. Both feature a stripped interior complete with sport seats and a roll bar. There is also the liberal use of carbon fiber on the exterior, with the front splitter, side skirts, rear diffuser and large (and adjustable) rear wing all made out of the lightweight material. Under the hood sits the water-injected straight-six from the M4 GTS, which makes 500 horsepower and 442 lb-ft of torque. Both cars make the sprint from 0-62 mph in 3.8 seconds, with all the power sent to the rear wheels.

So what are the differences between the two cars? Well, the interiors are styled differently and the exterior of the M4 DTM Champion Edition is only available in Alpine White. No word on whether or not BMW is going to force those racing stripes on customers. We've been critical of less-than-impressive special edition BMWs in the past but we'll give the German automaker a pass this time out. The BMW M4 GTS is a truly impressive car and having more of them on the road is not something we're going to complain about. Besides, the M4 DTM Champion Edition is much more better than the limited edition M4 the company trotted out last time Wittmann captured a DTM crown.
