Aston Martin Valhalla

The concept's aero design was a unique FlexFoil rear wing. The wing could change the car's downforce without changing its angle of attack; it is integrated into the bodywork and is claimed to generate no drag or aerodynamic turbulence.

The concept's interior has space for storing luggage behind the seats, a centre console and a phone mount for the driver. The car shares the race-inspired steering wheel from the Valkyrie and features unique wing shaped paddle shifters on the steering column. The car also has dihedral doors for easy entry and exit. As of July 2021, the production vehicle's interior has not been publicly revealed.

The chassis is a variation of the carbon fibre monocoque chassis of the Valkyrie with the body panels being produced from the same material. The chassis will be produced by Aston Martin while the aerodynamic body panels will be produced at Red Bull Racing. The car is planned to weigh less than 1,550 kg (3,417 lb).

When initially announced, the car was planned to use a 3.0L twin-turbocharged V6 engine as opposed to the V12 on the Valkyrie but would share the KERS system from the flagship sports car. A combined output of those two would be around 1,000 PS (735 kW; 986 hp). The engine was intended to be designed and developed in-house by the company and will use the Castrol Nexcel 90-second oil change system first used in the track-only Vulcan. The car is the first road car to use such a system. The exhaust system uses dual outlets which are placed on top of the car, similar to the Porsche 918 Spyder.^[5][6] However, in July 2021, the Valhalla was extensively redesigned, including switching engines from the in-house V6 to the Mercedes-AMG M178 LS2 4.0L twin-turbocharged V8 in conjunction with 2 electric motors, among many other changes. The new powertrain will develop 950 PS (699 kW; 937 hp). ^[7]
