Aston Martin Valkyrie V12 revs like a banshee

The gob-smacking new Aston Martin Valkyrie wants bragging rights in the hypercar arena.

As if an F1-like lay-back driving position was not enough, it appears the incredulously quick Valkyrie will rev higher and make more power than the mad F1-engined, quad electric motor-equipped Mercedes-AMG ONE.

Indeed, the F1-inspired Aston Martin Valkyrie appears to have pipped the Mercedes-AMG ONE as the highest-revving 'mainstream' hypercar of the modern era, with an 11,100rpm rev-limit.

The AMG will 'only' do 11,000rpm.

Aston Martin today announced the 6.5-litre V12 engine that will power the Valkyrie generates 740kW (1000hp) at 10,500rpm and has an 11,100rpm limit.

Peak torque is 740Nm at 7000rpm and the engine is built by British motorsport outfit Cosworth, whose CV includes countless F1 engine builds.

The Valkyrie's engine will be loud and it will guzzle fuel faster than you can say "how big is the tank?".

Meanwhile, the Mercedes-AMG ONE uses an F1-derived 1.6-litre turbo-petrol V6 to bang out around 500kW, which rises to 740kW with its four electric motors chiming in.

Earlier in the year Cosworth leaked details of V12 engine it is building for the Aston Martin Valkyrie, which will have a claimed combined petrol-electric power output of around 1130hp, or slightly more than 830kW.

Bragging rights doubled then.

Aston Martin has not officially confirmed the Valkyrie's full-biscuit output (with electric power) but has released a short video of the 6.5-litre V12 revving, which sounds unerringly like an F1 engine from the late 2000s, when they could rev to an astonishing 18,000rpm and above.

Aston Martin proclaims the new 65-degree V12 is an "absolute masterpiece" and Cosworth previously stated it is the most powerful naturally aspirated road car engine today.

Weighing just 206kg, the engine is an integral part of the Valkyrie's chassis. In other words, if the mid-mounted powerplant was removed, there would be nothing mechanical connecting the front and rear wheels.

Aston Martin and Cosworth say the screaming 6.5-litre V12 has hit all its target for "emissions compliance and durability" but it remains to be seen whether it will require a full rebuild every 50,000km like the AMG ONE's 1.6-litre F1 engine.

When mega-rich car collectors take delivery of their Aston Martin Valkyrie, the British sports car brand will be hoping it is placed at the top of the modern-day hypercar holy trinity, above the McLaren Speedtail and Mercedes-AMG ONE, thanks to its mega engine output.

It will be interesting to see what the McLaren Speedtail brings to the table next, as it's expected to use a development of the brand's new twin-turbo 4.0-litre V8 -- but with an EV boost.

"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," boasted Andy Palmer, CEO of Aston Martin Lagonda.

"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," he said.

Priced at around $4.5 million apiece, all 150 Aston Martin Valkyries are spoken for.

Indeed, all three vehicles in the holy trinity are completely sold out, so even if you wanted one or all of these multi-million-dollar weapons and had pockets deep enough to afford one, you may be out of luck.

Given their status, their value is only expected to rise.
