There's 1,064 combined horsepower from its plug-in hybrid powertrain, a bit more than previously expected. The vast majority—817 hp—comes from the twin-turbocharged 4.0-liter V-8 mounted behind the driver's head.
There's a flat-plane crankshaft in there, spinning new pistons and incorporating a dry sump lubrication system. It has bespoke camshafts and a new ignition system. Upgraded turbochargers fill the cylinders.
The remaining power arrives courtesy of three electric motors. One is integrated with the eight-speed dual-clutch transmission, serving primarily as a starter and generator to charge the battery pack. The other two are up front, turning each wheel for all-wheel-drive grip. The motors can operate independently for torque-vectoring wizardry on a race track, or you can punch up EV mode and drive for 8.6 miles at speeds up to 80 mph. Only the front motors are active in electric operation, and since the Valhalla has no reverse gear, they're responsible for backing up the supercar.
With everything working together, Aston Martin says the Valhalla reaches 62 mph in a "predicted" 2.5 seconds. Keep the pedal floored and you'll top out at 217 mph, a figure made possible by the car's active aero system. In most driving situations, the big rear wing remains down to preserve the Valhalla's clean exterior design. Switch to race mode, and it rises up rather dramatically. The front lip also extends out further, increasing downforce to a maximum of 1,322 pounds at 149 mph. From there, wing angles are automatically adjusted to maintain that force as speeds increase.
Aston Martin Valhalla production begins in the second quarter of 2025. Pricing isn't mentioned, and just 999 examples will ultimately be built.
