Aston Martin detailed changes to its Vanquish GT and Rapide S sedan on Wednesday. Big upgrades include the Touchtronic III eight-speed automatic transmission, which boosts economy and acceleration, a new engine management system and a more robust suspension for the Vanquish.
Output in the AM29 V12 engine grows to a peak of 568 hp at 6,650 rpm in the Vanquish, along with 465 lb-ft of torque at 5,500 rpm.
The updated transmission lowers the 0-60-mph time for the Vanquish from 4.1 seconds to a supercar-like 3.6 seconds, which confirms the car as the “quickest accelerating series production Aston Martin in the company’s history.”
The transmission also lowers shift times to 130 milliseconds, offers a sport mode for a more engaging experience and features multi-ratio downshifts that are offered when the driver holds the downshift paddle under braking. The car then selects the lowest gear possible before exiting the turn. Adaptive drive recognition, meanwhile, tailors shift points to each individual driver. It relearns every time you start up the car.
Carbon emissions drop by about 10 percent thanks to changes in the final drive ratio -- changes that also make the Vanquish capable of 200 mph.
As for chassis improvements, Aston says the new dampers on the Vanquish are 15 percent stiffer in front and 35 percent stiffer in the rear. Additionally, a new torque tube reduces transmission noises in the cockpit.
Moving to the Rapide S, output grows from its previous version a few ponies to 552 hp, while torque is equal to the Vanquish at 465 lb-ft. With help from the new eight-speed, sprint times drop from 4.7 seconds to 4.2 seconds. Fuel economy is also improved 13 percent.
The Rapide skips the new shocks of the Vanquish, instead receiving larger front brakes. Both cars get new rear-suspension bushings that are 20 percent stiffer than before.
Lightweight wheels and new paint color options are offered on the exterior, including Diavalo red—previously only available on the V12 Zagato, while new interior colors and trim are available on both the Vanquish and Rapide S.
Aston Martin says that details on market-specific pricing will be available closer to launch, which begins this fall.
