Talk about a kick ass gadget. BMW’s new M5 let’s you simply push a button to add 100 to the already powerful 400 horses. As you drive, you can choose between total system horsepower of either 400 or 500. Pretty impressive for a sedan.
According to Business 2.0 you can drive your M5 under one of over 279 configurations:
The M5’s suspension, gearing, traction, and horsepower can be configured in 279 different ways, a confusing cornucopia that forces the driver to choose between paddle, center stick, or automatic shifting, 400 or 500 horses, comfort or sport ride, and so on.
