Aston Martin Walton on Thames, the longest serving Aston Martin Dealership in the World are thrilled to bring to market this stunning Aston Martin Vantage 4.7 S Coupe Sportshift II. Originally our demonstrator this Vantage has been well cared for throughout its life with the previous keeper making a significant investment to have the clutch replaced to a twin plate Clutch fitted by Bamford Rose.The engine in Vantage S is the same 4.7-litre 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 430 bhp (321 kW:436 PS) at 7,300 rpm and torque of 490 Nm at 5,000 rpm representing an increase of 10 bhp and 20 Nm respectively. The modifications allowed for improved acceleration time of 0 to 60 mph in 4.0 seconds, 0.3 seconds faster than the base model. The 7-speed Graziano automated manual gearbox is razor sharp and has a carbon fibre driveshaft attached which 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. A major difference in the Vantage S is the inclusion of the Sportshift II transmission, a 7-speed automated manual gearbox, as standard. The Sportshift II is 24 kg lighter than the 6-speed Sportshift fitted on the standard Vantage. This contributes, along with other weight-saving parts, to a total vehicle kerb weight of 1,610 kg, a reduction of 30 kg over the standard V8 Vantage.
