Aston Martin Valkyrie, the most powerful car in the world

When the Aston Martin Valkyrie makes its official debut likely later this year it will have a record-breaking engine mounted behind the passenger compartment. In a tweet, Cosworth declared, "We’re famous for breaking records and our latest engine, the Aston Martin Valkyrie 6.5-litre V-12, will be the world’s most powerful naturally aspirated road engine with 1,130 bhp." The power figure also makes good on Aston Martin's promise to deliver a supercar with "around" 1,000 hp. And unlike other Aston Martin road cars, the 6.5-liter V-12 is a tuned and tweaked recipe baked inside the halls of Cosworth. Aston Martin Red Bull Racing team principal Christian Horner believes the car could topple Porsche's Nürburgring record recently set with the 919 Evo. A record-breaking engine won't come at a small price, though. Each example of the Valkyrie fetches $2.6 million. Aston Martin plans to build 175 examples of the supercar, of which 25 will be AMR Pro variants.
