At the heart of the uprated Vantage is the latest, fifth-generation evolution of Aston Martin’s normally aspirated 5.9-litre V12, codenamed AM28. The main development for the AM28 over the fourth-generation AM11 unit used in the latest Vanquish, DB9 and Rapide S is a new Bosch engine-management system.
The power of the V12 Vantage S’s engine matches the 565bhp of the Vanquish, a 55bhp increase over the V12 Vantage. Torque is also increased to 457lb ft at 5750rpm, a 37lb ft gain. Low-rev torque is up by 52lb ft to 376lb ft at 1000rpm, the result of which is a flattened and fattened torque curve.
The V12 is mated to a seven-speed automated manual transmission, which has been taken from the V8 Vantage and given a longer final drive ratio to allow for the higher top speed. It is controlled by paddle shifters mounted on the steering wheel.
The adoption of this Sportshift III transmission, as Aston calls it, means the end for the six-speed manual in the V12 Vantage. Minards said the car needed to have two pedals instead of three “to make a business case” for it. Autos are far more popular in China and North America, the likely two biggest markets for the V12 Vantage S.
The Graziano-supplied seven-speed automated ’box is also 25kg lighter than the six-speed manual, and Minards said it was “better able to exploit” the engine’s potential than the old transmission, with “motorsport shift speeds”.
Economy and CO2 figures are expected to improve over the V12 Vantage’s thanks to engine improvements, reduced weight and the new gearbox. Kerb weight is 1665kg, 15kg less than the V12 Vantage in standard specification (25kg has been taken out with the gearbox swap, but 10kg has been added elsewhere).
Bilstein supplies the three-stage adaptive damping technology. Its appearance on the V12 Vantage S marks the first time that adaptive dampers have been used on the Vantage. The spring rates are taken from the Vanquish.
Being able to select from Normal, Sport and Track modes means that “you don’t have to compromise low-speed refinement for high-speed ability”, said Minards.
The Servotronic steering system, with two levels of assistance, is another Vantage first. The two levels of assistance are linked to the adaptive dampers. Sport and Track modes add extra weight and a precision feel. “Having the two levels of feel makes it better and easier to drive in more situations,” said Minards.
Other developments include Brembo-supplied carbon-ceramic brakes adapted from the One-77’s, a Continental-supplied two-stage Dynamic Stability Control system that can be fully switched off and a smaller, lighter exhaust.
New 10-spoke lightweight alloy wheels can be added to save another 3.3kg, and they can be specified with standard P Zero Corsa dry-weather tyres or P Zero all-weather rubber as a no-cost option. Minards described the sum of all these changes as “altering the entire chassis recipe” of the V12 Vantage.
The most notable feature of the revised look, penned by Aston design director Marek Reichman, is the adoption of a new front grille. Inspired by the CC100 concept that appeared at the Nürburgring 24 Hours earlier this month, the new grille loses the distinctive aluminium vanes in favour of a carbonfibre frame with a dark background mesh that can be made out of carbonfibre or titanium. The grille is also wider to improve cooling.
