The 4.7 litre V8 engine has been modified to deliver peak power of 430 bhp (436 PS / 321 kW) at 7200 rpm and torque of 490 Nm (361 lb.ft) at 5000 rpm representing an increase of 10 bhp and 20 Nm respectively and is signified with a black engine plenum. The increase has been achieved through a valved air intake system and an aggressive spark strategy. The air intake system valve opens above 3500 rpm to allow more air to flow into the engine, which helps optimise performance at precisely the right part of the torque curve.
At the core of the Aston Martin V8 Vantage S is the new seven speed Sportshift™ II automated manual transmission, offered as standard and delivers exceedingly rapid gear changes, twenty per cent quicker than Sportshift™. The extra gear permits shorter well-spaced ratios taking advantage of the optimum torque, which combined with a shorter final drive ratio of 4.182:1 delivers quicker acceleration and an enhanced sporting feel. The inherent benefits of a single clutch system reduces complexity and significant weight over a dual clutch solution. Sportshift™ II allows the driver to take an increased level of control, modulating the throttle pedal to achieve the desired type of gear change. In addition, the Vantage S features a ‘Sport’ button which quickens the gear changes and gives the driver a more aggressive throttle response while also opening the exhaust bypass valves across most of the engine speed range perfectly characterising the ‘S’ variant.
The Aston Martin V8 Vantage S remains a practical day to day sports car featuring a 300 litre boot with convenient tail gate opening in coupe guise, while the Roadster has an automatically retracting fabric hood which can be operated up to 30 km/h.
