On 25 January 2011, Aston Martin unveiled the V8 Vantage S, a more potent version of the V8 Vantage available in both coupé and Roadster body styles and designed to create a more sporty experience than the standard V8 Vantage. The engine is the same 4.7-litre "AJ37" V8 found in the base Vantage, but with improved intake airflow, new mufflers, and new programming that keeps the exhaust system's bypass valves open for longer. The 4.7-litre V8 engine has been modified to deliver a peak power of at 7,300 rpm and torque of at 5,000 rpm representing an increase of 10 bhp and 20 Nm respectively. The modifications allowed for improved acceleration time of 0 to in 4.5 seconds and a top speed of for both the coupé and Roadster. Engine output flows through a new single-clutch 7-speed Graziano automated manual to a limited-slip rear differential; the carbon fibre driveshaft spins in an aluminium torque tube. From there, power is applied to the pavement via a set of (285/35) Bridgestone Potenza tyres on 19-inch cast aluminium wheels. Bushings, springs, and dampers were stiffened for the S model and the steering rack is quicker than in the base model. These modifications result in an exceptional level of response. The aerodynamic enhancements include a deeper front bumper with carbon fibre splitter, larger side sills, a carbon fibre diffuser and a larger tailgate lip designed to sharpen the handling on the road. Additional visual differences include new wheels.
