The M5 sits atop the 5 Series lineup. It's powered by a hand-built 500-hp 5.0-liter V10, with suspension and brakes enhanced to match all the power. Adaptive headlights allow the lenses to turn slightly with the steering, throwing light around a curve in the direction of travel. The M5 also features the MDrive button on the steering wheel, offering a one-touch function that changes the settings on the car to an enhanced sporting character. New for 2007 is a no-cost option six-speed manual transmission in the BMW M5.
