The Aston Martin Valhalla: A Closer Look at the Powertrain
The heart of the Aston Martin Valhalla lies in its powerful engine, sourced from Mercedes-AMG. Taking the 4.0-litre V8 as a base, Aston Martin opted for the flat-plane version found in the AMG GT Black Series. This unique V8 configuration offers a more even gas flow and smoother balance compared to traditional cross-plane designs, although it may be prone to secondary vibrations.
In its original form in the AMG GT, this engine produced 720bhp and 590lb ft of torque. However, with enhancements such as larger compressors, new cams, and exhaust manifolds, the Valhalla boasts an impressive 817bhp and 632lb ft of torque. Aston Martin claims that both power peaks are achieved at 6700rpm, a rare feat in road car engineering.
Adding to the powertrain is a supplementary motor integrated into the eight-speed dual-clutch automatic gearbox, providing additional support during acceleration. This innovative setup allows the motor to engage different gears depending on driving conditions, ensuring optimal performance at all times.
Further enhancing the driving experience is an electronically controlled limited-slip differential at the rear axle, along with two electric motors powering the front wheels. While Aston Martin does not disclose individual motor outputs, the combined power of all components reaches an impressive 1064bhp and 811lb ft of torque.
Complementing the powertrain are features such as electric power steering, adaptive Bilstein dampers, electric regeneration, and brake-by-wire technology. The Valhalla also boasts active aerodynamics capable of generating up to 600kg of downforce, ensuring optimal handling at high speeds.
Constructed with a carbonfibre tub and bodywork, the Valhalla features aluminum subframes for the suspension, utilizing double wishbones at the front and a multi-link setup at the rear. This meticulous engineering ensures a perfect blend of performance and agility on the road.
