The GT4 takes advantage of the Vantage’s immensely rigid bonded aluminium chassis, providing the ideal platform for a race car. Minor racing safety modifications including an FIA approved roll cage and racing ‘bag’ petrol tank along with weight saving measures are made to the standard road car to convert it into a class winning race car.
In 2010, it won its class at the Dubai 24 Hours following this up with further endurance race wins at the
24 Hours, Silverstone 24 Hours and Spa 24 Hours. It also won its first major international championship victory in the European GT4 Cup.Revisions are central to the Vantage S, with a quickened steering rack ratio of 15:1 compared to 17:1 on the standard car and a larger
diameter front brake disc with new six-piston front brake calipers
New springs and dampers, and wider rear wheels also contribute to chassis revisions. A stability control system specifically tuned to the Vantage S along with a brake module providing features such as Hydraulic Brake Assistwhich provides assistance in emergency braking situations, and Hill Start AssistBespoke tires have been developed with Bridgestone to optimise road holding enhancing dynamic feel.The Vantage S epitomises every attribute of the V8 Vantage and pushes the driver experience beyond what we have offered before,Martin. “It combines dynamic exhilaration with all the charming finesse, beauty and practicality already associated with the Vantage range.At the core of the 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 Vantage S benefits from a new exhaust muffler and bypass valve creating a highly vocal exhaust
