The new SUV will only be sold as a high-performance M model, and this concept you see here is about 80 to 90 percent of what the production version will be when it arrives at the end of next year. Two BMW roundels on the rear window are reminiscent of the M1. The XM has the same 122.2-inch wheelbase as the X7 SUV, and it rides on a set of 23-inch wheels. Even the two-tone bronze and gray color scheme could be a production option. The XM’s plug-in-hybrid powertrain uses BMW’s twin-turbocharged 4.4-liter V-8 engine paired with an electric motor and produces 750 horsepower and 737 pound-feet of torque, making it the most powerful production M car ever. The XM also outmuscles the Lamborghini Urus (641 horsepower), Porsche Cayenne Turbo S E-Hybrid (670 horsepower), and the Dodge Durango SRT Hellcat (710 horsepower).
