The N400 was a special edition of the V8 Vantage produced to celebrate Aston Martin’s efforts in the Nurburgring 24Hr race, where Aston Martin had entered N24 race-cars in the SP8 class for the previous two years.

Based on the Vantage, it cost an extra £11,000 from a standard Vantage and was available as coupe or roadster, with only 240 of each planned for production.
The unique model was provided with a power and torque upgrade (yielding an extra 20bhp produced 200rpm higher and 12lbft extra torque), and the Sports Pack (which was then unreleased) for the Vantage (including new spring, shock ratings, and lightweight wheels) and some cosmetic tweaks.

The N400 visual addenda were the Nurburgring circuit map stitched into the armrest, clear rear light lenses, forged 19-inch five-arm twin-spoke alloy wheels, and micro-spin alloy veneer interior.
​While 240 units of the Roadster were originally planned, Aston Martin Heritage Trust registrar Tim Cottingham has stated that the number actually built is believed to be just 195, making this one of the final examples assembled.​

This example was manufactured in 2009 and is finished in Karussel Orange (one of only three colours exclusive to the model, the other two being Bergwerk Black and Lightning Silver), and there’s lots of black leather trim, available with several stitching options, a little more aluminium and a stitched Nür­burgring circuit map on the armrest. First UK registered in March 2009; the V8 Vantage N400 Roadster is fitted with the 4.3-litre V8 and six-speed Sport-shift gearbox.
