The new 1160bhp Aston Martin Valkyrie hypercar has run in public for the first time at the British Grand Prix.
The hybrid machine is powered a Cosworth-developed naturally aspirated 1000bhp 6.5-litre V12 that can rev to 10,500rpm and produced 546lb ft at 7000rpm, along with an electric motor developed by Rimac and Integral Powertrain Ltd that produces 160bhp and 207lb ft. Peak combined outputs of the system are confirmed to be 1160bhp at 10,500rpm and 664lb ft at 6000rpm.
Aston Martin test driver Chris Goodwin drove the machine around Silverstone during a break in on-track action during qualifying for the British Grand Prix. Goodwin was not focused on a lap time, with the intent to showcase the machine to the public.
Aston Martin boss Andy Palmer said the run was a “milestone in not only Aston Martin’s history but for our industry as a whole.” He added the machine would offer “unrivalled levels of performance in a package that is technologically beyond anything else.”
The car ran at Silverstone in a special black and red livery that reflected Aston's tie-up with the Red Bull Racing grand prix team, which helped to develop the car. It was presented alongside a Red Bull F1 car in a similar special livery.
Autocar recently visited Cosworth's base in Northampton during durability testing for the petrol engine, touted as the ultimate 12-cylinder motor. We got a chance to see it perform on a dynometer, which was simulating repeated laps of the Silverstone circuit.
Cosworth has designed the engine and will build the 150 units that will be fitted to road-going Valkyries, plus around 25 track-only AMR Pro versions.
Cosworth managing director Bruce Wood confirmed the 1000hp target was agreed well before the first prototype was built, and that the V12 is set to serve as a structural component. As in a race car, it will be bolted directly to the Valkyrie's tub and have the gearbox and rear suspension hung from it. The drive gears for the camshafts are located at the rear, in an effort to insulate the cabin from some of the noise they make at high revs.
