1,000 bhp? That's no problem for Aston Martin's new V12 Valkyrie engine

Aston Martin has turned its new hypercar engine up to 11 (11,100 rpm to be precise)! More details of Aston’s frankly unbelievable powerplant, developed in conjunction with Cosworth, have been revealed this week, and it’s shaping up to be an engineering masterpiece.

Displacing 6.5-litres the normally aspirated V12 sets exceptional new standards for maximum rpm and specific output with a certified peak power output of 1000bhp at a mind-blowing 10,500 rpm, before continuing on to a maximum rpm figure of 11,100: figures that are unprecedented for a naturally-aspirated, emissions-compliant road car application. Peak torque is 740Nm at 7,000rpm. With these peak outputs purely delivered by the ICE (Internal Combustion Engine), Aston Martin Valkyrie’s performance figures will be further boosted by a battery hybrid system, details of which will be revealed by Aston Martin in due course…

The performance of the engine might be incredibly impressive, but the lengths Aston Martin has gone to ensure maximum build quality are equally impressive. For starters, the engine weighs just 206kg (454lb), whilst also being engineered in as a structural member of the car’s frame. Perhaps the most impressive aspect of the engine’s construction is the fact that, apart from the major castings- block, cylinder heads, sump and structural cam covers- the majority of the engine’s internal components are machined from solid material.

Yes, you read that correctly. 

Machined. From. Solid. Material.

The crankshaft alone is produced during an exacting six-month process. Aston Martin describe the process as follows:
The Valkyrie's powertrain has been designed in conjunction with Cosworth and with technical input from Red Bull Racing.

“Starting life as a solid steel bar 170mm diameter and 775mm long, it is first roughed out, then heat treated, finish machined, heat treated again, gear ground, final ground and superfinished. Upon completion 80% of the original bas has been machined away and some six months have passed, but the end product is a crankshaft that’s an astonishing 50 per cent lighter than that used in the Aston Martin One-77’s V-12- what was for a time the world’s most powerful naturally aspirated road car engine”.
Aside from being amazingly light the Valkyrie's engine acts as a structural member of the car's frame.

Aston Martin haven’t worked alone on this impressive power plant though. Performance motor experts and F1 legends Cosworth and Red Bull Racing have also deeply involved in the project. Cosworth’s hand in the project is particularly evident in the engine’s amazingly low-weight and the use of the engine as a stressed member (remove the engine and there is nothing joining the front wheels to the back). Bruce Wood, Cosworth Managing Director, described his company’s involvement in the Valkyrie project as ‘being an immense source of pride’:
The Valkyrie's power plant features internal components that have been machined from solid material over a period of six months!

“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. Decades in Formula 1 taught us to expect a pretty demanding specification from someone 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. It’s been a fantastic partnership between Aston Martin, Red Bull and Cosworth with each party bringing a distinct clarity of vision that has proved essential in delivering an internal combustion engine way beyond anything previously seen in a road car application”.
Only 150 road-going examples of the Aston Martin Valkyrie are set to be built with prices ranging between £2 - 3 million.

If you fancy getting your hands on one of these amazing street legal hypercars you’re out of luck. Only 150 road-going examples of the Valkyrie will be built, and all of them have been purchased already fetching prices of between £2-3million. Buyers should expect to receive their cars later in 2019.
