BMW HP4The BMW HP4 is an evolution of BMW's HP2 series with the S1000RR's inline-four engine. Like the S1000RR, the HP4 claims 190 hp at 13,000 rpm and 83 ft-lb. at 9750 rpm. Like its predecessor, the HP4 will have four ride modes, Rain, Sport, Race and Slick. The HP4 is the first production model to come with dynamic damping control (DDC) technology that adapts the suspension's damping characteristics to road conditions. DDC uses information from sensors to electrically control the suspension's regulation valves to optimize damping. BMW has also equipped the HP4 with new launch control system, which maximizes acceleration from a standing start.
