Ring Racer, stylized as Ring°racer, is a Formula One-themed roller coaster which was due to open on August 15, 2009 at the Nürburgring race course as part of the Nürburgring 2009 project. It was originally planned to accelerate from 0 to 217 kilometres per hour (135 mph) in 2.5 seconds. parallel to the grand prix track. However, two defects in the launch system delayed its opening until 2013. On 3 September 2009, engineers attempted to raise the ride to its full and intended speed as it had been testing at a lower power, however this caused a series of explosions in the pneumatic system and caused injuries to seven people, and shattered multiple windows in the nearby buildings.
