AC Mark 6 Cobra
from Classic to Modern
The AC Mark 6 sports car was introduced at the April 2009 Top Marques Car Show in Monaco as a two door, two seater convertible, while later prototypes were premiered at the Geneva Motor Show in both 2011 and 2012.
Externally, it looked very much like a Cobra, and was offered as both a convertible and a fixed head coupe.
The body consisted of an innovative hybrid combination of a fibreglass base with an aluminium overlay.
It was mounted on a space frame chassis containing tubular sections which increased its strength whilst, at the same time, keeping weight to a minimum and reducing production costs.
An important change in respect of the power plant was a switch from the Ford Windsor V8 engine in the original AC Cobra to one built by Chevrolet.
The Mark 6 was hand built, and available in five versions, using engines from the Corvette:
The V8 engine was very flexible, and would pull away smoothly even from 1000 rpm, but it really came into its own between 40-100 mph.

The Mark 6 represented a number of firsts for the company since it was:
The target market for the Mark 6 was the US and Europe.
Initially, from 2009, the AC Mark 6 sports car was built for AC Cars by Gullwing Gmbh in Germany, who were the licensee.
However, AC subsequently introduced a network of local production and distribution centres, which were intended to eliminate the US shipping costs incurred with the rolling chassis during the production of the original AC Cobra Mark 1-3.
Consequently, the three main centres chosen were AC Heritage Centre in the UK, AC Germany in Dresden, and Iconic Motors in the US.
Iconic Motors have subsequently developed the Iconic AC Roadster sports car, fitted with a 6.8 litre, V8 engine that developed 825 bhp, and 680 ft/lbs of torque, with a top speed of 210 mph, and a 0-60 mph time of less than 3 secs.
