Aston Martin Vantage S Roadster
The Aston Martin Vantage range comes of age with the new V8 Vantage S characterised by a host of new driver-focussed features all designed to push the honed dynamics of the standard Vantage to a new benchmark level.
With every new model we continue to evolve and enhance our VH architecture,” said Aston Martin Product Development Director, Ian Minards. “The engineering team at Gaydon looked at every single performance attribute of the V8 Vantage, from engine and transmission to suspension, steering, brakes and tyres and considered what was required to make this car deserving of the coveted ‘S’ badge. The result is a pure driver-focussed package that, in both the coupe and Roadster form, exploits and emphasises the sporting nature of the iconic Vantage.”
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. Aggressive spark strategy uses sophisticated electronics to ignite the fuel in the engine at precisely the right time allowing it to run at its most powerful. It can also recognise higher octane fuel and extract the optimum performance from the increased rating.
The power and torque delivery on the Vantage S is delivered at the most frequently used mid range engine speeds which creates tractable and effortless acceleration. Most demand for power and torque is in the mid-range which on the V8 Vantage S is where the greatest torque is delivered at 5000 rpm.
The 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.
