Aston Martin has updated its entry-level V8 Vantage range for 2012, incorporating the most comprehensive update to the cars since 2008.

These live shots, taken at the range's debut at the 2012 Geneva Motor Show this week, show off the stunning V8 Vantage Roadster model in a beautiful pearl white finish.

The car’s powertrain still consists of a 4.7-liter V-8 but peak output has been lifted to 430 horsepower and 361 pound-feet of torque. You’ll be quick to note that those numbers are lifted from last year’s Vantage S.

Further enhancements center on the V8 Vantage’s chassis, which also gets a few items from the Vantage S. Quicker steering, bigger brakes and wider tires have all been fitted to further enhance the V8 Vantage’s dynamics.

The standard six-speed manual transmission remains, but the optional six-speed Sportshift automated manual transmission has now been replaced with a seven-speed Sportshift II. With an additional gear, closer ratios, lower final drive and a quicker, refined shift quality, this new gearbox--designed and manufactured specifically for Aston Martin--provides faster and more precise shifts and optimizes acceleration.
