Official: £850k Aston Martin Valhalla to land in summer with 1079bhp

Like AMG's old GT Black Series, the Valhalla's V8 features a flat-plane crank and is said to be "the most advanced, responsive and highest-performing V8 engine ever fitted to an Aston Martin". It also breathes through a lightweight exhaust system that exits through the top of the rear deck and contains adjustable flaps that give "an authentic Aston Martin sound character". 

Like the Ferrari SF90, the Valhalla uses only its front electric motors to drive in EV mode, which it can do for eight miles and at speeds of up to 80mph, but in normal driving situations, electric power is split across both axles as needed to supplement the V8's output.

It reverses exclusively in electric mode, too, saving weight by negating the need for a conventional reverse gear in the eight-speed DCT, which has been fitted with an electronic limited-slip differential to improve traction and agility and can offer up two gears at once to allow the EV and combustion motors to operate in tandem. 

Housing the all-new powertrain is a bespoke carbonfibre tub that gives "maximum stiffness with minimum weight penalty". A dry weight of just 1655kg gives a power-to-weight ratio of 643bhp per tonne, while aerodynamic-enhancing bodywork elements – including huge venturi channels underneath and an active front splitter and rear wing – inspired by the Valkyrie's F1-style set-up are claimed to generate 600kg of downforce at 150mph. 

Pushrod suspension features at the front and a multi-link set-up at the rear, with dampers and springs mounted inboard to reduce unsprung mass, The entire set-up is stiffened and “dramatically” lowered in Track mode and can be raised at low speed to clear speed bumps. 

By using more subtle bodywork elements to enhance downforce, Aston's designers were given free rein for the overall silhouette, without the need for such dramatic wings, intakes and outlets as on the Valkyrie. The design is much cleaner, more overtly road-focused and extensively altered from that of the concept. 

The prominent roof scoop, forward-hinged dihedral doors, swooping rear deck and one-piece rear wing remain, but a completely new treatment for the front, rear and side bring the supercar into line with its more mainstream siblings. 

A wraparound version of Aston's trademark grille features at the front, for example, below larger, rounder matrix LED headlights, while the rear diffuser has been heavily toned down for a more production-friendly set-up. There is a more angular-looking side skirt, too, sharper side vent designs and, obviously, wing mirrors, which were absent from the show car.

The production-spec wheels, meanwhile, are 20in in diameter at the front and 21in at the rear and wrapped in Michelin Pilot Sport Cup tyres.
