Styled to resemble “the silhouette of a sabretooth on the prowl,” Kahn Design’s Vengeance coupé has been confirmed for limited numbers production.

At £300,000, the retro two-seater is considerably more expensive than the £133,000 Aston Martin DB9 on which it’s based, but company founder Afzal Kahn described it as “extremely good value for a limited edition coachbuilt car”. By comparison, the coachbuilt Speedback GT, David Brown’s small-production Jaguar XKR-based special, costs £564,000.

Taking its inspiration from 1980s and 1990s Astons, the Vengeance will feature a reworked front grille and a wide stance, with 20-inch front alloys and 21-inch rears.

“Launching the Vengeance is the realisation of a dream I’ve had since childhood, to design and produce my own car,” said Kahn. “I’ve worked in the industry my whole career, and I want to leave a legacy which I can be proud of.

“The design has gone through several iterations over the years and I’ve taken my time in selecting the right partners to prototype and manufacture the car, ensuring it represents the pinnacle of quality and perfection.”

“I’ve kept every aspect of the underlying car, from the crash structures to airbags. Mechanically, it’s unaltered - why change perfection?

“This is coachbuilding in its traditional sense - taking a tried and tested product and working solely on the aesthetic.”

There are no details on what’s under the bonnet, but the likelihood is that it will be the DB9’s 5.9-litre V12 engine. This naturally-aspirated 510bhp unit takes the DB9 from nought to 62mph in 4.6 seconds.

Manufacture of the Vengeance will start in Coventry at the end of 2015, with Aston Martin confirming a supply agreement with the company. Five cars will be built initially, followed by ten more in 2016.
