Aston Martin has recently divulged the “dynamic enhancements” that will be equipped on the 2015 models of the Vanquish GT and Rapide S.
New paint options are now available for both models, including the Diavolo Red that was originally reserved for the V12 Zagato. Also available are lighter ten-spoke alloy wheels that save as much as 7 kilos per corner than the standard wheel.
Inside, additional color options for the leather trim can either be a blue-black Dark Knight scheme or a Fandango Pink. Exclusive options to the Rapide S is the Duotone leather seat that can be finished in Sahara Tan or Vibrant Red. Moreover, the Rapide S features a headline that can be blended with quilt, leather or fabric.
A new 8-speed Touchtronic gearbox, co-developed by ZF, comes as standard for the new Vanquish GT and Rapide S. It can change gears in as little as 130 milliseconds and has multi-ratio downshifts that can be done by pulling and holding down the shift paddle.
Aston Martin says the gearbox uses a transaxle design that improves over the stock figures made by the standard model. The Vanquish GT is now able to do a 0-100-km/h time in just 3.8 seconds while the Rapide S in 4.4 seconds. Both cars have become more efficient as it averages 13.18 km/l on highway speeds.
The 6.0-liter AM29 V12 in the Vanquish GT now produces 575 PS, 3 PS more than standard, while the V12 in the Rapide S is able to create 560 PS, which is 2 PS more than standard. Improvement in torque figures was also achieved as it gained 10 Nm more for both cars. The boost in power was due to a decrease in exhaust gas backpressure that resulted from the ratio adjustment, which also benefitted top speed as both cars are now capable of hitting 322 km/h or more.
Improvements were also done on the suspension of the Vanquish GT as it now has upgraded dampers that are 15% thicker at the front and 35% thicker at the rear. The Rapide S on the other hand, gets larger front brakes. A reworked brake booster and tighter suspension bushings aid both cars.
“This has been a detailed piece of work involving careful consideration of many technical parameters including gear ratios, software integration and shifting strategies. This has delivered a significant step change in both vehicle performance and economy whilst preserving the unique Aston Martin V12 driving experience”, said Ian Minards, Product Development Director at Aston Martin.
Availability of the new cars will start at the third quarter of 2014, with more specifics on the market price and options to follow as well.
