Aston Martin’s latest track focussed AMR vehicle has been revealed, but this time, rather than announcing a stand-alone range the British sports car builder has rolled-out a retrofit upgrade for its existing Vulcan customer racing cars.
With the Vulcan already entirely developed to be the ultimate track car, the move to make an even more track-ready model seems unusual. But in this instance the AMR treatment shows that Aston Martin hasn’t simply been resting on it laurels, honing the package as it goes.
Vulcan owners can opt to add the upgrade package to their existing vehicle and while the 611kW 7.0-litre V12 engine remains unchanged, the Vulcan’s aero package has been given a thorough rework.
Up front the AMR Pro package adds louvred panels over the front wheel arches to extract high pressure air, countering lift. Changes to the front splitter see turning vanes added to improve steering response, while dive planes have been added to the nose to increase downforce.
At the rear a massive new dual-plane rear wing maximises downforce and lends the Vulcan an even more intimidating look than the single-plane original.
Minor weight savings are also achieved thanks to an optimised carbon fibre engine cover which saves 5kg compared to the previous version.
For statisticians, fans and pub-trivia boffins the changes result in a huge increase in downforce, from the previous Vulcan’s 3150Nm to 4000Nm (by comparison Aston Martin’s Le mans winning Vantage GTE achieves 3104Nm of downforce).
The changes also alter the Vulcan’s aerodynamic balance, bringing the vehicle's centre of pressure closer to the middle of the car for increased traction, front end stability, and steering responsiveness.
Aero upgrades don’t tell the whole story either, with the AMR Pro package also including shorter gear ratios for more rapid acceleration.
“We worked hard to ensure it’s not a monster to drive, so it was important the AMR Pro upgrade remains true to that objective. By increasing the overall level of downforce front and rear, but also improving the balance of the car we’ve done just that,” Aston Martin Racing works driver, Darren Turner, said.
“The Aston Martin Vulcan AMR Pro feels more agile and responsive to steering inputs. When you get the aero working through a fast corner it really is an unbelievable feeling. I can’t wait to see the customers’ faces when they experience it for themselves!”
Aston Martin’s Advanced Operations division has already started upgrade work on the 24 Vulcan customer cars, with this weekend's Goodwood Festival of Speed to play host to the Vulcan AMR Pro’s dynamic debut.
