Ford Motor Co.’s Aston Martin Lagonda Ltd. subsidiary will unveil its new V8 Vantage Roadster Nov. 29 at the 2006 Los Angeles Auto Show.

The new roadster was developed alongside the V8 Vantage Coupe, which went on sale in 2005. Like the coupe, it touts a bonded aluminum VH (vertical horizontal) architecture that is unique-to-Aston Martin.

The roadster’s body is composed of sophisticated materials, such as lightweight alloys, magnesium and advanced composites, which greatly reduce the car’s weight while increasing its rigidity, Aston Martin says.

It is powered by a naturally aspirated 4.3L V-8 supplied by fellow Ford subsidiary, Jaguar Cars. The 380-hp mill is capable of powering the car to 60 mph (97 km/h) from a standstill in less than 5 seconds, Aston Martin says. Top speed is 175 mph (282 km/h).

The Vantage Roadster will be offered with either a traditional 6-speed manual transmission or the new Sportshift 6-speed sequential manual.

It will be built at Aston Martin’s plant in Gaydon, near Warwickshire in the U.K.

Pricing is expected to begin at $110,000, with units arriving in dealerships in second-quarter 2007.
