15. M550d Xdrive

Years: 2012 and on
Market: Europe
Take a look at the specs: All-wheel drive, a six-cylinder diesel with three (really!) turbochargers, 546 lb-ft. of torque, 0-62 in 4.7 seconds, and 44.8 miles per gallon. It's like they took all of our automotive fantasies and shoved them into a single vehicle. The future of BMW M GmbH promises to be amazing, as long as they filter out that whole swimming-pool-in-a-pickup-truck-bed thing we see pictures of sometimes.
