Ferrari FF

Ultimate all-wheel drive
all-wheel drive is helpful on slick surfaces; but it can sap car's performance. the 4RM system on the new 208mph, 650-horsepower Ferrari FF is the first to employ two separate, electronically controlled front- and rear-wheel-drive units, which eliminates the heavy secondary driveshaft, thereby reducing weight and allowing the FF to drive like a true sports car. normally the rear wheels do the driving, but when the car's predictive algorithms sense that the rear wheels are about to slide, it sends a fraction of the 6.3-litres V12 engine's power to the front, keeping this rarity (only 800 were made this year 2011) out of the body shop.$295,000
