To commemorate the company’s racing successes at the Nürburgring, Aston Martin released the limited edition N400 at the 2007 Frankfurt Motor Show. The N400’s 4.3-litre V8 was tuned to produce 400 bhp hence the name, and the car also featured a sports pack which included lightweight graphite-finished wheels, uprated springs and dampers and a new rear anti-roll bar. The N400 was available in three special paint colours; Bergwerk Black, Lightning Silver and Karussell Orange. Each N400 came with perforated leather trim, including a map of the Nürburgring stitched on the center armrest, and a numbered plaque.
Aston Martin tested the car at the Nurburgring Nordschleife circuit where it was able to complete a lap in under eight minutes. The N400 package was available as either a coupé or Roadster with a total of 480 examples (240 coupes, 240 Roadsters) being built, in note of the fact that there are 480 seconds in 8 minutes.
