As the Aston Martin range continues to evolve a few choice options have become available for the brand's "entry-level" sports cars as well as more details of the new flagship model. The revised 313kW, 4.7-litre V8 introduced in 2008 and the standard six-speed manual transmission are unchanged but the optional six-speed Sportshift automated manual transmission has been replaced by a seven-speed designed and assembled just for Aston Martin. "The additional gear and closer ratios," Aston Martin says, "generate quicker and more refined shifts and optimised acceleration."BIGGER, QUICKEROther dynamic improvements, borrowed from the Vantage S, include quicker steering thanks to a new steering column and re-valved power-steering pump and bigger brakes (new 380mm ventilated cast-iron front discs and six-piston calipers) equipped with include hill-start assistance for tricky incline starts.The car's tyres are also 10mm wider than those of the previous model. The V8 Vantage has also undergone several styling changes inspired by the Vantage S and N400 limited edition. The front bumper houses a larger air-intake to feed the engine and front brakes and a rear diffuser and race-derived sills add to the Vantage’s more muscular look. The Vantage S, tuned to deliver 321kW and 490Nm from its V8, continues as the more focused model in the range with the Sportshift II seven-speed transmission standard. THE RANGE: Aston Martin's range for 2012, excluding the recently-revealed V12 Zagato.
