The Aston Martin Rapide is a 4-door, 4-seater, high-performance sports saloon, which the British luxury marque Aston Martin introduced in early 2010. It was first presented as a concept car at the North American International Auto Show in 2006 and the production version was shown at the 2009 Frankfurt Motor Show. The Rapide name is a reference to the Lagonda Rapide, a four-door, four-seater saloon produced by Lagonda, now a part of Aston Martin. The new Rapide is the company's first 4-door fastback saloon since the Lagonda which was discontinued in 1990. The Rapide is based on the DB9 and is underpinned by the VH Generation III platform. The first cars rolled off the production line in May 2010, initially built at a dedicated plant at the Magna Steyr facility in Graz, Austria. The factory initially planned to build 2,000 cars per year, but production was relocated to England in 2012 after sales did not meet production targets. As part of the 2014 facelift and revisions to the Rapide, the V12 engine is upgraded and now has a power output of 410 kW (550 hp) and torque of 620 Nm (457 lb ft). Performance improvements include a top speed of 306 km/h (190 mph) and acceleration from 0 to 100 km/h (62 mph) reduced to 4.9 seconds. CO 2 emissions are reduced by 23g/km to 332g/km. The Rapide S received further revisions in 2015, with a new 8-speed Touchtronic III automatic transmission and power increase to 412 kW (552 hp) and 630 Nm (465 lb ft) of torque, resulting in an acceleration of 0 to 100 km/h (62 mph) in 4.4 seconds and an increased top speed of 327 km/h (203 mph). Aston Martin opted to ending its production by sub-contractor Magna Steyr in the middle of 2012, six years earlier than expected. Production of the car was also halted temporarily in May 2011. In the face of a diminishing market for luxury saloons, and to match output to shrinking sales, Aston Martin had to cut annual production from 2,000 to 1,250 in June 2011, and may go as low as 500 annually. A Rapide S was entered in the 2010 24 Hours Nurburgring. Drivers included then Aston Martin CEO Ulrich Bez. It finished second in the SP 8 class. This Rapide S was powered by a new technology introduced by Alset GmbH, a Hybrid Hydrogen system that enables the car to use hydrogen and petrol individually or at the same time in an internal combustion engine. The Rapide S was the first car to race the 24 Hours of Nurburgring with hydrogen fuel.
