(one simply cannot employ so mundane a descriptor as “base” in connection with an Aston Martin) are a bit elusive. S means a little more motor, a little more brake, a little more rubber, a little less weight, some small trim distinctions, and, of course, a little more money. The engine is Aston’s familiar 4.7-liter aluminum V-8, with improved intake airflow, new mufflers, and new programming that keeps the exhaust system’s bypass valves open longer. The net is 430 hp and 361 lb-ft of torque, gains of 10 ponies and 15 lb-ft. Although it’s a small gain in output, the S’s new transmission (more on that in a moment) should help it whittle the Vantage’s 0-to-60-mph time down from the 4.3 of the last example we tested to about four flat. Beyond that, the menacing V-8 sounds that emerge when the bypass valves open up and the engine soars toward redline are almost worth the price premium on their own, with or without the extra thrust.
