Aston Martin Releases Tech Data on 1,000+ hp Valhalla Hypercar

Aston Martin reveals full technical details of the Valhalla plug-in hybrid model that claims the title of the most powerful V-8 sportscar the brand has ever produced.

Replete with technological firsts, the model is the first to use the automaker’s new 4.0L twin-turbo flat-plane crank engine, developed with Mercedes-Benz AMG, and is the first to use its new 8-speed Dual Clutch Transmission (DCT), which incorporates an e-Motor and electronic rear differential.

The Valhalla, limited to a global run of 999 examples with a price tag expected to be $800,000, employs an electrified powertrain that claims a combined power output of 1,063 hp, easily beating the recently unveiled Aston Martin Vanquish turbocharged V-12 at 823 hp.

Its power is split between the 816 hp twin-turbocharged gasoline V-8 with a further 247 hp provided by two E-motors mounted on the front axle and a third E-motor built into the 8-speed DCT transmission, which sends dedicated drive to the rear axle. Top speed is thought to be about 217 mph (349 km/h) with the 0-to-62 mph (100 km/h) sprint time of 2.5 seconds.

E-motors are powered by the battery using a special cooling system to aid electric boost for frequent and successive power demands. This claims full power potential can be called up immediately, while recuperation is strong when decelerating.

The battery’s cooling system circulates a high-tech electrically non-conductive coolant fluid through the entire power pack to keep its 560 individual cells at optimum temperature.

The front axle is driven solely by a pair of innovative radial flux interior permanent E-motors designed solely for Valhalla. These front motors are integrated within a front electric drive unit to allow front-wheel torque vectoring. This is used in electric-only driving the front wheels only with a range of 8.6 miles (14 km) and a top speed limited to 80 mph (129 km/h).

Aston Martin’s integrated vehicle dynamics control and brake systems manage the requirement for drive and, with front torque vectoring and the rear axle’s electronic limited-slip differential, control drive to all four wheels.

The rear axle is driven by the V-8 engine, with additional contribution from the third electric motor built into the transmission.

Valhalla’s combustion engine employs a dry sump lubrication system, as seen on racing cars and motorcycles, to ensure adequate oil supply even under high lateral forces on the racetrack.

Its flat-plane crankshaft, another racing and motorcycle engine technology, uses ignition firing alternating from one bank of cylinders to the other, eliminating the residual gas issues of the cross-plane engine.

New camshafts and exhaust manifolds further improve the gas exchange and the pistons have been designed for higher peak pressures while also being lightened.

The two twin-scroll turbochargers are roller-bearing-mounted to improve response. A larger compressor wheel is also employed to allow the turbos to deliver an increase of almost 20% of air per hour compared to Aston Martin’s most powerful cross-plane crank V-8  engine, seen in the DBX707.

Inside the cabin special features include raised footwells for a low hip-to-heel seating position and lightweight, one-piece carbon fiber seats for maximum support.

Also, the steering wheel shape has too been inspired by Formula One design and features a one-piece carbon fiber armature.

Its infotainment system includes a Race mode layout with a large linear tachometer and shift lights inspired by Aston Martin Aramco Formula One Team drivers at their Silverstone Headquarters.

During road driving the display also features an expanded view function, such as full-screen navigation map.

The automaker expects Valhalla to be ready for first global deliveries of the by the second half of 2025.

Aston Martin CEO Adrian Hallmark says: “Four years ago we set out on a journey to transform the Aston Martin brand by taking its historic and unmatched luxury credentials and adding cutting-edge, F1-inspired technology and class-leading performance, with the aim of taking on the most successful brands in the world.

“On paper and on track, Valhalla delivers the most driver-focused, technologically advanced supercar, with true hypercar performance and yet on the road it is as useable and enjoyable as any Aston Martin. A unique proposition, designed to be the most elegant and exciting product in the market.”
