Aston Martin has revealed fresh details of the high-revving, naturally aspirated 6,5-litre V12 engine that is set to power the Valkyrie.
According to the Gaydon-based automaker, the Cosworth-developed V12 was created as the “ultimate expression of the internal combustion engine”.
Displacing 6,5 litres, the 65-degree V12 boasts a certified peak power output of 746 kW (that’s a pleasingly round 1000 bhp) at a lofty 10 500 r/min. Peak torque of 740 N.m is on tap at 7 000 r/min, while the engine revs to a maximum of 11 100 r/min.
Of course, the Valkyrie’s performance figures will be further boosted by a battery hybrid system, with Aston Martin set to reveal these details at a later stage.
The firm says that aside from the major castings – block, cylinder heads, sump and structural cam covers – most of the engine’s internal components are machined from solid material. These include Titanium conrods and "F1-spec" pistons. The result is an engine that weighs 206 kg.
“To anyone with a drop of petrol in their blood, a high-revving naturally aspirated V12 is the absolute pinnacle. Nothing sounds better or encapsulates the emotion and excitement of the internal combustion engine more completely,” said Andy Palmer, Aston Martin Lagonda president and group chief executive officer.
“Despite the apparently insurmountable challenges it presented, there was never any question that the Aston Martin Valkyrie would make do with anything less. From the outset the team at Cosworth were unflinching in their commitment to achieving benchmarks which pushed the boundaries of the possible. The result is a quite extraordinary engine. One which I doubt will ever be surpassed.”
