Now We Know That The Aston Valkyrie Will Produce 1160hp At 10,500rpm

At last Aston Martin has confirmed the power figures for the Valkyrie, now that the prototypes are taking shape and the design of its engine and its hybrid system finalised. The Cosworth-built 65° naturally aspirated 6.5-litre V12 engine is a clean-sheet design for the Valkyrie, said to be in the spirit of the ultra-high-revving Formula 1 engines of the 1990s though benefitting from two decades of progress in design, material and manufacturing knowledge. Its peak power output of 1000hp (which works out at 153.8hp-per-litre) comes at at 10,500rpm, but it can continue on to a maximum 11,100rpm—a world first for a naturally-aspirated, emissions-compliant road car. With the addition of the hybrid system, power is raised to 1160hp at 10,500rpm.

The engine’s peak torque of 546lb ft is, not surprisingly, delivered lower down the rev range, at 7000rpm. That’s boosted to 663lb ft at 6000rpm by the hybrid system, which is a Formula 1 KERS-style boost system developed by two main technical partners; Integral Powertrain Ltd, who supplied the bespoke electric motor, and Rimac for the lightweight hybrid battery system. The battery pack itself also includes all relevant sub-systems and carries the vehicle’s power electronics, and the electric motor also aids the mechanical performance of the gearbox. In the same spirit of integral engineering, both the engine and gearbox casing act as stressed members of the Valkyrie’s structure, with the gearbox providing rear suspension mounting points, eliminating the need for an additional rear subframe.

Vice president & Special Vehicle Operations officer, David King said, “Aston Martin Valkyrie is set to be the ultimate hypercar in the automotive world and these performance figures underline that statement. Red Bull Advanced Technologies, Cosworth, Rimac and Integral Powertrain Ltd. have been fantastic partners in the development of this powertrain, ensuring that we have already created a hybrid system that is emissions-compliant and ready to begin fitting to our first physical prototypes. I am, as I’m sure the rest of the world is, incredibly excited to see and hear the first of these cars on track.”

I’m looking forward to seeing this on the road, and like the idea of a naturally aspirated V12 with the capability to rev to 10,000 rpm and put out the power figures now being released.
As for its design, I think that is much more pleasing than the other cars of its type being produced by the likes of McLaren, Ferrari etc – a very ‘clean’ design.
Hats off to AM for pressing ahead…

For all of the investment and time devoted to this engine, it seems to me that 153.8hp per liter is just not that spectacular.

Why can’t I get excited about this? Perhaps because it is so alien to the world of cars that I grew up in, this last 40 yrs. It’s styling is alien, the performance numbers, alien and I imagine you’d have to have fairly alien driving skills to master such a machine. Bring on more, light weight, lower cost, amazing, real world vehicles please!!! Otherwise why doesn’t Aston use its engineering skills to start building rockets and fly people to the moon & beyond? They could go look for aliens while they’re at it…
