Aston Martin has taken the wraps off of its brand new road weapon with a palpable track appetite. The Vantage S supplies its driver with 430 concentrated horsepower produced by the already proven big 4.2L V8. From the transmission to the brakes, anything is trimmed for speed. The Vantage S is debuting the seven-speed Sportshift 2 that is touted to have 20 percent advantage over its predecessor and combines that with shortened steering reaction, stiffer dampers, bigger brakes and better fuel economy resulting in a 18 mpg combined rating. Due to a hidden exhaust bypass valve, the S is told to welcome its competition with an impressive speed-suggesting scream.
