1. 2016 BMW M5
The BMW M5 is a powered up 5-series sedan packing a 560 horsepower twin-turbo V-8 under the hood. The standard transmission is a 6-speed manual. The optional 7-speed dual-clutch automatic is a little bit quicker, but is less fun to drive. The BMW M5 is the most powerful sport sedan you can get with a manual transmission. The suspension sacrifices some comfort for track worthy performance, with stiffer springs, dampers, and anti roll bars, the ride height lowered, and less compliant front suspension bushings. This gives the M5 superb handling, but the ride can be stiff at times, even with the electronic settings dialed back to their comfort settings. The steering is responsive and tight, thanks to the hydraulically assisted rack-and-pinion steering that is finely tuned by BMW.
