Aston Martin’s Valkyrie V12 engine lets rip at 11,100 RPM

Developed in partnership with Cosworth, the naturally aspirated engine will produce 1,000 bhp and deliver a maximum rpm of 11,100. Despite these heady figures, the powerplant weighs in at just 206kg and complies with all relevant emissions standards, according to Aston. Peak torque from the combustion engine will be 740Nm at 7,000 rpm, but overall performance figures will be boosted by a battery hybrid system, details of which are yet to be released. The Valkyrie, designed by Adrian Newey, is being pitched by its developers as the fastest street-legal car in the world.

“Being asked to create a naturally aspirated V12 engine fit for what will surely be one of the most iconic cars of all time is an immense source of pride for Cosworth,” said Bruce Wood, Cosworth managing director.

“Decades in F1 taught us to expect a pretty demanding specification from someone with Adrian Newey’s unsurpassed track record, but when we started talking about specifics of power, weight, emissions compliance and durability combined with ever harder and sometimes conflicting targets, we knew this would be a challenge like no other.”
