Aston Martin is marching towards a future with hybrid and electric supercars. And the new Valhalla is one of the first steps in that direction, with the introduction of a new hybrid architecture.
Built with chassis, aerodynamic, and electronics expertise forged in Formula One, and a cutting-edge hybrid powertrain technology at its heart, Valhalla is a technological showcase.
Valhalla is built around a new a carbon fibre tub for maximum stiffness with minimum weight penalty. Featuring Formula One style push rod front suspension complete with inboard mounted springs and dampers reducing unsprung mass and provides a brilliant packaging solution. Together with the rear-end’s multilink design, Valhalla uses Multimatic Variable Spring rate and Adaptive Spool Valve (ASV) Damper units providing adjustable ride frequency for exceptional performance on road and track. In addition to stiffer suspension, Track mode sees ride height dramatically reduced in order to maximise downforce. At the other end of the speed scale, a front axle lift system raises the nose for improved approach angle on awkward inclines.
At the heart of Valhalla is its all-new PHEV powertrain, which features three motors; foremost of these is a rear-mid-mounted 4.0 litre twin-turbo bespoke V8 engine. The most advanced, responsive and highest performing V8 engine ever fitted to an Aston Martin, it features a flat-plane crankshaft for increased responsiveness. Revving to 7200rpm and developing 750PS, it sends drive exclusively to the rear axle.
Supplementing this new V8 engine is a 150kW/400V battery hybrid system utilising a pair of E-Motors; one mounted on the front axle and the other on the rear axle. The electric system contributes a further 204PS for a headline combined power output of 950PS. When driven in EV mode battery power is directed exclusively to the front axle. In other driving modes battery power is split between front and rear axles, the percentage sent to each axle constantly varies according to driving demands. In certain situations, 100% of battery power can be sent to the rear axle, supplementing the full force of the ICE V8 for maximum performance.
Completing the powertrain is an all-new 8-speed DCT transmission. Exclusively designed and built for Aston Martin, this new paddle-shift gearbox has been developed specifically for the hybrid era. Featuring e-reverse (which utilises the PHEV’s electric motors and thereby saves weight by negating the need for a conventional reverse gear) the transmission also features an Electronic Limited-Slip Differential (E-Diff) on the rear axle for maximum traction and handling agility.
Electrical power is also used to enhance low speed control and response as well as provide reversing capability. And, thanks to the instantaneous torque from the E-Motors, the hybrid system augments the V8 engine to deliver sensational standing start acceleration and in-gear response. Outright performance is further aided by the E-Motor and V8 ICE being able to run different gears in the DCT simultaneously, which enables a maximum torque delivery of 1000Nm.
Running in EV-only mode, Valhalla will be capable of a maximum 80mph / 130km/h and has a zero-emission range of 15km. Predicted CO2 (WLTP) is less than 200g/km. Unleashing all 950PS the Valhalla will reach a top speed of 217mph / 330km/h and will complete the sprint from 0-62mph in just 2.5 seconds. In terms of outright track capability, a stunning 6:30 Nürburgring Nordschleife lap time is being targeted.
With a target dry weight of less than 1550kg Valhalla will have an unrivalled power-to-weight ratio compared to its class rivals.
Valhalla, the luxury brands first series production mid-engined supercar will be available in both left-hand and right-hand drive, expanding its appeal across international markets. Cockpit room has been increased compared to the Aston Martin Valkyrie.
Full LED Matrix headlights with adaptive functionality and high-beam assist deliver excellent forward vision in the dark, and Dual Zone Air Conditioning provides high level of occupant comfort. In order to comply with the latest regulatory requirements, Valhalla also incorporates the latest Advanced Driver Assistance Systems. These include Auto Emergency Braking, Forward Collision Warning, Active Cruise Control, Blind Spot Monitoring and Rear View Parking Camera (with Surround View option).
Dynamic development of the Valhalla will be the task of Aston Martin’s award-winning dynamics team and complemented with an enviable pool of talent which also includes Aston Martin Cognizant Formula One Team drivers Sebastian Vettel, Lance Stroll and Nico Hulkenburg.Source: Aston Martin
