Aston Martin Valkyrie revealed in near-production form
Unprecedented levels of downforce are needed if this road car is to fulfil the promise of Aston boss Andy Palmer that it will “lap Silverstone as fast as an F1 car”.
Aston Martin-Red Bull’s £2.5m hypercar has extreme aerodynamics, light weight and more than 1000bhp
Aston Martin has unveiled a near-production version of its Adrian Newey-inspired hypercar, the Valkyrie.
The car’s exterior shape is now “about 95% ” finished, according to designers inside the firm’s Gaydon top-secret design centre at Gaydon.
The essence of the £2.5 million, 1000bhp-plus two-seater’s proportions have been known for many months but Newey, revered as the world’s greatest creator of Formula 1 cars, is still finding ways of increasing its aerodynamic downforce as his colleagues finesse details such as headlights, stoplights, scoops and badges.
Unprecedented levels of downforce are needed if this road car is to fulfil the promise of Aston boss Andy Palmer that it will “lap Silverstone as fast as an F1 car”. Sources at Gaydon have already suggested the car will generate up to 4000lb (1816kg) of downforce at top speed.
Autocar has had exclusive access to a fully detailed, full-sized model of the Valkyrie, shown recently to a small group of customers at the Monaco Grand Prix. The car, pictured here, was recently used as a demonstrator for prospective owners keen to try the Valkyrie’s F1-style, raised-feet driving position, and to begin deciding the specification of their cars.
Aston Martin and Red Bull Racing expect to start making the planned run of 150 cars late next year, on a schedule to deliver the first Valkyries to customers during 2019. Jockeying for ownership has begun already: after recent advertisements purporting to offer Valkyrie build slots for sale, Palmer made it clear that Aston Martin would do whatever it could to resist such premium market trading.
Working together, Aston’s designers and Red Bull Racing’s Newey have made considerable changes since the first iteration of the Valkyrie was unveiled at Aston’s HQ last year. The biggest alteration is a set of new openings between the cockpit and front wheel arches, designed to increase downforce. Aston Martin’s designers have had the unusual job of incorporating these slots harmoniously into the Valkyrie’s overall styling, to ensure aesthetic quality as well as aerodynamic function.
“We’re around 95% done,” said chief designer Miles Nurnberger. “Much of what you see from outside is the actual structure of the car which had to be signed off quite early. Non-structural areas are still subject to evolution as Adrian continues finding improvements.
“Ordinarily, the last thing we’d want is to cut a hole in one of our surfaces, but these new vents work the front wings so much harder that we’ve found a significant gain in front downforce. They have their own functional beauty, but we’ve finessed them without harming the way they work. They also work as windows through which owners can view our fabulous wing-section front wishbones.”
The extent to which the Valkyrie’s main proportions are shaped in the wind tunnel means it makes a complete break from supercars of the past. A low, two-seat, beetlebacked passenger pod with no rear window sits between two, large, full-length venturi tunnels. They draw air from beneath the car to feed a very prominent rear diffuser. These tunnels are key to the car’s aero performance, said Aston design boss Marek Reichman, who has worked on this project side by side with Newey.
Despite their aerodynamic obsession, the Valkyrie’s creators are at pains to point out that this car is comfortable and surprisingly spacious, accommodating “a wide range of shapes and sizes”. Occupants must step over the lower aero structure to gain access through a pair of gullwing doors reminiscent of access to a Le Mans racer, but with larger openings.
“It has been a tremendous challenge making the interior packaging work,” said Aston designer Matt Hill. “We’ve embraced Red Bull’s F1 ethos and come at things from a different angle. We’ve started from a position that seemed impossible and found a way to make it work, fighting for millimetres everywhere.” The result of that work is comfortable accommodation for two fairly large adults.
“The battle has been worth it,” said Hill. “It has been fantastic watching customers trying the car for size. They love the ritual of getting in, and how it feels behind the wheel. They’re genuinely surprised at how the car seems to swallow them.”
Valkyrie owners will be able to have tailored seats made, if they desire, moulded directly to the car’s carbonfibre tub. Aston is pleased with early reactions to the race-style feet-up driving position, which creates a sense of occasion and allows occupants to be reclined further than normal to create head room. A fourpoint harness is standard.
The Valkyrie’s interior treatment reflects the keenness of Aston’s designers to reduce driver distractions. The traditional exterior mirrors are replaced by rearfacing left and right-hand cameras, whose reduced size also helps cut drag. The lack of a rear window means there’s no need for a central mirror. All important switchgear is on the steering wheel, which is almost rectangular in shape and has a screen on its central boss showing all vital information. There’s a supplementary central screen for minor functions, but ‘minimalist ergonomics’ is one of the design team’s main objectives.
Most of the Valkyrie’s mechanical package has been decided and is proceeding on plan. The mid-engined car uses a normally aspirated 6.5-litre Cosworth V12, tipped to produce more than 900bhp, and the hybrid powertrain (conventional power is augmented by a kinetic energy recovery system) is understood to have delivered 1130bhp during testing. That means Newey’s oft-stated power-to-weight target of one horsepower per kilogram should be comfortably reached, given that the weight is just over 1000kg, ready to drive. The V12’s power reaches the centre-lock magnesium wheels through a seven-speed paddle-operated gearbox made by Ricardo (which also builds Bugatti’s gearboxes and McLaren’s engines). It exhausts through the upper body, Le Mans style.
Aston says there will be distinct race and roads versions of the Valkyrie, linked by their styling but with “big differences” in weight and aero downforce. Both will use a unique central carbonfibre tub built by Multimatic, which also builds the structure for the latest Ford GT.
Little is known of the suspension design so far, except that it uses long, race-style wishbones at both ends. The obvious challenge is to create a system that can withstand huge downforce at top speed yet provide acceptable low-speed, roadcar comfort. “We want this car to be pure, simple and light,” Newey told Autocar. “It needs to major on comfort as well as performance.” This may be proving Newey’s biggest challenge so far.
Aston Martin, Andy Palmer: It’s a landmark car
Signing off the Valkyrie for production represents “a huge milestone”, according to Aston Martin boss Andy Palmer (right), who describes managing the expectations of technical lead Adrian Newey, design lead Marek Reichmann and production boss David King as the “toughest but best challenge to have”.
Palmer said: “The challenge has been working with three very strong-willed people with three very different agendas. Fighting one corner is Adrian, who wants a no-compromise performance car that sets new technical standards. Then there’s Marek, who is responsible for ensuring every Aston is as beautiful as it can be, something he’s not used to compromising on. And then there’s David, who has to make it, to a schedule, to a budget and so on. He has immovable deadlines that the other two constantly try to push.
“At times, it has been interesting. They have all pushed each other so hard. But it’s challenges like these that get you out of bed in the morning.”
Despite the base car costing around £2.5 million and 150 road and 25 track versions being built, Palmer said the project is unlikely to make money. “We’ll be lucky if this project washes its face, but that’s not why we do it,” he said. “This is the 1977 Vantage V8 all over again — a landmark car that gives you the poster-on-the-wall effect. Kids will fall in love with it. Dads will talk about it. It’s a symbolic car.
“Aston Martin is achieving so much, and this is the best symbol of all that. We are getting our confidence back — even some swagger, but never arrogance — and what better way to express that confidence than in the Valkyrie.”
