Aston Martin this week offered details of its new 2012 Vantage range, with a revised engine among the highlights.

The entry-level 4.7-litre V8 Vantage produces 420 bhp and 346 lb-ft of torque and, while the six-speed manual is still standard, the optional six-speed Sportshift becomes the optional seven-speed Sportshift II. In addition to the extra gear, Sportshift II offers closer gear ratios, lower final drive and an improved shift quality.

Chassis enhancements feature developments borrowed from the Vantage S. Quicker steering, bigger brakes and wider tires are all on board.

Styling changes include a lower bumper housing a larger air intake, rear diffuser and race-derived side sills. Technical and styling changes apply to Coupe and Roadster, starting at $124,289 for the coupe and $139,664 for the roadster. Both get standard satellite nav, satellite radio, front and rear parking sensors, cruise, remote garage door opener and Bluetooth.

The $144,550 Vantage S develops 430 bhp and 361 lb-ft from its V8. A unique sports exhaust system offers a little ear candy for enthusiasts. Carbon fibre detailing distinguishes it from the V8 Vantage.

The V12 Vantage continues unchanged for 2012, powered by a 6.0-litre V12 with 510 bhp and 420 lb-ft torque, for a 0-100 km/h time of 4.2 seconds and a top speed of 305 km/h.

The V12 Zagato joins the lineup later this year.
