M4 DTM Champion Edition: 190 mphThe BMW M4 DTM Champion Edition was a celebratory limited edition made in tribute to Marco Wittman's Deutsche Tourenwagen Masters (DTM) driver's title in 2016. You'd expect a car with such noble and lofty intent in its design to have sporty and confident styling and be remarkably quick, and the M4 DTM Champion Edition does not disappoint. All 200 units feature a 3.0-liter twin-turbo straight-six producing 500 horsepower and 443 lb-ft of torque, thanks to which the M car can catapult to 60 mph in 3.8 seconds and achieve a top speed of 190 mph. BMW attributes that massive output to the water injection technology, which offers a 16 percent improvement in power compared to the standard M4. Performance aside, the M4 DTM Champion Edition is also unique and eye-catching in the usual limited-edition style. It was offered in a striking Alpine White only and has numerous cues that point to its DTM racing connection.M4 GTS (F82): 190 mphThe BMW M division really hit its stride with the M4 back in 2016, and the M4 GTS is another example of that success. As in the case of the M4 DTM Champion Edition above, one of the key ingredients here is a water-injected S55 twin-turbo inline six-cylinder engine. Unsurprisingly, this motor puts out similar numbers to the DTM car above; the M4 DTM Champion Edition actually uses a modified version of the M4 GTS's engine. On the M4, this translates into a 3.7-second 0-60 mph sprint and 190 mph top speed. It's also worth remembering that the BMW M4 GTS once completed the famous Nürburgring Nordschleife circuit in just 7.28 minutes, which makes it one of the fastest BMW M cars to do so. But for a car that rips up the road at such blistering pace, owners surely need a capable braking system to provide immediate stopping power when required. Hence, BMW equipped the GTS with carbon-ceramic brake rotors for hauling back all that power, with road-hugging Michelin Pilot Sport Cup 2 tires also fitted to keep the car glued to the road. M6 Competition Edition: 190 mphBMW M's opulent, attention-grabbing M6 was already a fine grand tourer with a 4.4-liter twin-turbo V8 engine that was astounding at 560 hp and 500 lb-ft of torque. However, adding the higher-performance Competition Edition package took things up a notch numbers wise, with output rising to 600 horsepower and 516 lb-ft to enable the sprint from zero to 60 mph to happen in a lightning-quick 3.8 seconds. Top speed is 190 mph with the optional M Driverʼs Package; otherwise it maxes out at 155 mph. The BMW M6 Competition Edition comes standard with 20-inch light-alloy wheels, power-adjustable, heated multi-contour front seats with lumbar support, memory settings for the front seats, Alcantara simulated suede roof lining, a heads-up display, and the option of either a Harman Kardon surround sound system or a 16-speaker Bang & Olufsen surround sound system with 1,200 watts of power.
