Aston Martin sidestepped the LA Auto Show this year, which is a real shame as we would love to have seen the gorgeous new Vanquish S, unveiled today, in the metal. Aston's ultimate grand tourer now carries the S specification, with the second-generation Vanquish receiving an uprated engine, chassis and aerodynamics. The 6.0-liter naturally-aspirated V12 has been upped to 595 horsepower in the UK and EU, and to 580 hp elsewhere, with torque remaining at 465 lb-ft.

That equates to a 0.3-second quicker 0-62 mph sprint of 3.5 seconds, while top speed remains unchanged at 201 mph. A revised intake system allows for a greater volume of air into the engine at high revs providing non-stop power all the way to redline. The eight-speed transmission has also been revised for faster, more precise gearshifts and greater refinement at low speeds. A retuned suspension remains supple when cruising, but gives the Vanquish S more sharpness in the sportier modes. An exposed carbon fiber front splitter and rear diffuser as part of a new bodykit distinguish the Vanquish S from the regular model it has replaced outright, as do new quad exhaust outlets and the Vanquish S badge.

Optional extras include new five-spoke alloys (20-inch 10-spoke wheels come standard) carbon-fiber hood louvres, and painted graphic packs. The interior looks spectacular, finished in new 'Filograph' quilted leather and optional satin-chopped carbon-fiber fascia panel. A 1,000-watt Bang & Olufsen 13-speaker sound system comes standard with US-models receiving a satellite radio. Available as both a Coupe and Volante, the new Aston Martin Vanquish S will be priced from $294,950 with deliveries to start next month.
