V8 Vantage N400 Roadster

(2007 - 2008)


As if the new DBS coupe was not enough for Aston Martin, only three weeks later came the announcement that another two cars would also be premiered at the Frankfurt Motor Show during September 2007. These were the DB9 LM and the long awaited, slightly more powerful V8 Vantage, the N400. In addition to the coupe version, the N400 was also available as with Roadster coachwork.

The N400 featured a few tweaks over the standard car. This included a useful power upgrade to the 4.3 litre V8 engine, lifting peak power to 400 bhp and peak torque to 420 Nm. The car also came equipped with a new Sports Pack as standard which offered subtly different driving dynamics tailored to enthusiasts who were seeking even more responsive handling. The Sports Pack comprised of unique lightweight graphite-finished aluminium wheel type with diamond turning (already fitted to the Sports Pack DB9), with up-rated springs and dampers. The N400 also included a number of exterior design changes, including a revised side sill design, Magnum Silver bonnet and side strake meshes, clear rear lamp lenses and a bright finish grille.

Interior enhancements included perforated black leather seats, micro-spin alloy facia trim and a unique numbered sill plaque. The N400 was only available in three new exterior colours; Bergwerk Black, Lightning Silver or Karussell Orange (the first time that orange has been a standard colour for an Aston Martin I believe), with either Sportshift or conventional manual transmission. Additionally, the N400 came equipped with a range of optional equipment fitted as standard, including Satellite Navigation, 700W Aston Martin Premium Audio System, Bluetooth telephone preparation, HID headlamps, cruise control and memory/heated seats. In the Karussell Orange car, the seat stitching was course orange and a map of the Nürburgring was embroidered on the arm rest, the black and silver cars in course silver or sometime red or even black thread.

AML intended limiting production of the N400 to just 480 examples (240 coupes, 240 Roadsters) – why 480? well that’s how many seconds are in 8 minutes, the time that the N400 could lap the Nürburgring. Almost all cars were built during March and April 2008. It is now believed that 195 N400 Roadsters were actually built making the edition especially desirable to collectors.

The special series of ‘N’ cars continued with the 4.7 litre N420 in 2010 and the N430 in 2014.
