WATCH: Aston Martin Valkyrie and Valhalla hit the track

Images and video footage of the Aston Martin Valhalla has been released for the first time ahead of its North American debut at the Pebble Beach Concours d'Elegance over the weekend.

Carefully described as a "dynamic concept", rather than a 'prototype' or 'mule', it's not known how advanced the Valhalla is in its development but the Aston hypercar certainly looks complete enough to be driven hard by ex-McLaren test driver, Chris Goodwin.

Previously named the AM-RB 003, Aston Martin has already revealed that it plans to make just 500 Valhalla, each priced from around £1 million ($A1.9m) when it goes on sale in 2021.

For that you get a hypecar that takes all the knowhow from the $4.5 million Valkyrie and distils it into a track-bred rival for cars like the McLaren Senna.

Once again developed in partnership with Red Bull Racing, the Valhalla will come powered with an advanced twin-turbo 3.0-litre V6 hybrid that will feature an electric motor driving the front axle.

Combined, the Valhalla will produce at least 800kW – that's enough for a 2.0 second-sprint to 100km/h and a top speed of around 400km/h.

Featuring an enormous rear diffuser and twin high-pressure bonnet vents, the Valhalla is expected to feature plenty of active aero tricks, including something called FlexFoil that sees the rear wing distort at high speed to improve the amount of downforce generated.

Beside the Valkyrie, the new Valhalla won't be quite as light as the 1000kg Valkyrie, but it will come with a more traditional supercar cabin and far more creature comforts.

Inside, which is accessed via a pair of dihedral doors, will be a complex steering wheel incorporating all of the car’s suspension, engine and traction control modes, and even some luggage and storage space.

As well as the Valhalla, Aston Martin released more footage of the Valkyrie dancing its way around Silverstone's high speed F1 circuit.

With deliveries set to start later this year, it's thought the car pictured is now a late-stage prototype, following the car's dynamic debut in July.

Powered by an 865kW/900Nm petrol-electric 6.5-litre V12, that can rev to 11,100rpm, the Valkyrie is set to raise the hypercar bar for performance with the car-maker boasting that, at some F1 circuits, the road car will be capable of qualifying mid-pack.

With that in mid, a race version of the Aston hypercar has already been confirmed for the 2021 Le Mans 24 Hour.

Aston Martin has announced that it has already sold-out the 150 Valkyries it said it would build, with each costing their wealthy owner a $4.5 million, before options.
