What to Expect with the 2012 M5: A Technological Tour de Force BMW has teased us numerous times with its upcoming 2012 M5 super sedan. With the Concept M5 premiering soon at the Shanghai auto show, we may not have all the details on the M5, but we're just about there. The heart of any BMW M5 is its powerful engine, and the soul is its rear-wheel drive. While BMW has yet to release any output figures, the engine should at least match the 4.4-liter twin-turbo V-8 in the X5M and X6M that produces 555 horsepower and 500 pound-feet of torque. BMW says the new blown eight-cylinder will have a higher output than the 500-hp, naturally aspirated, 5.0-liter V-10 that we enjoyed in the 2010 M5. To increase efficiency 25 percent over the V-10, which was rated at a mere 11/17 mpg, the 2012 model will use an automatic start-stop function in combination with a seven-speed dual-clutch transmission to help save fuel. Drivers less interested in fuel economy will be happy to know BMW still uses M Drivelogic to tailor the DCT's performance to an individual driver's taste. While the powerplant may attract a lot of attention, those in the know realize BMW's suspension is what makes taking an M to the track or a favorite back road so rewarding. Riding lower than a typical 5 Series, the M5's suspension tuning will take advantage of decades of racing knowledge and countless development hours spent lapping the Nuerburgring. For 2012, the M5 uses an Active M differential to split power between the rear wheels, which improves handling by allowing the outer wheel to spin faster in a turn. Putting the power to the pavement are lightweight 20-inch, five-spoke, forged alloy wheels wrapped in 265/35 ZR20 Michelin tires. BMW assures us the M5 has large enough brakes to lap the 'Ring right from the showroom. Get a free and easy new car price quote in minutes.
