<< Prev Page 2 of 3 Next >>  As with its coupe sibling, race car technology runs right through the DNA of the V12 Vantage S Roadster with, for instance, CNC machined combustion chambers and hollow camshafts just two examples of track technology feeding through to the road.Another clear example is the new car's SportshiftIII 7-speed transmission. Engineered to exploit the full sporting potential of the V12 engine, the latest generation SportshiftIII hydraulically actuated automated manual transmission provides motorsport-style paddle shift changes for optimum performance delivery. The unit, which replaces the six-speed manual gearbox found in the previous V12 Vantage Roadster, is also appreciably lighter - saving 20 kg versus its forebear. This race-derived and motorsport-proven technology - used routinely in Aston Martin Racing's race-winning Vantage GT4, GT3 and GTE competition cars - provides for great driver control with only milliseconds of torque interruption and delivers precise and swift gear changes. The SportshiftIII transaxle, developed in conjunction with transmission experts Oerlikon Graziano, joins an extensive array of new sport and track-focused developments that ensure the V12 Vantage S Roadster is fully equipped to exploit the huge performance potential of its 6.0-litre naturally aspirated engine. The use of three-stage adaptive damping, allied to three-stage DSC and two-stage ABS, allows the driver to more precisely tailor the car's dynamic character. 'Normal', 'Sport' and 'Track' modes provide a broad swathe of dynamic performance that can be tuned to better suit the driver's requirements. The system also governs the level of power steering assistance offered. Working alongside the extended chassis capabilities is a 'Sport' mode, controlled via a button on the centre console, that alters throttle response, gearshift speed and timing, and exhaust note to, once again, tune the character of the car to the driver's requirements. Optimum braking performance is delivered via the specially-created carbon ceramic discs all round, with near-identical brakes appearing on the brand's ultimate GT, the Vanquish. Meanwhile a whole new lightweight exhaust system - derived from that of Aston Martin's most expensive and exclusive production model, the One-77 hypercar - is wonderfully sonorous. The ZF Servotronic power assisted steering offers a quick, slick, 15:1 ratio and, linked to the adaptive damping button, provides two-mode steering assistance designed to best match the 'Sport' or 'Normal' settings generated by the Adaptive Damping System. << Prev Page 2 of 3 Next >> |
