Aston Martin and Mercedes-Benz have entered into a new technical partnership which allows Aston access to a large range of Mercedes’ powertrains, but the British brand isn’t sure which one to choose for its upcoming Valhalla hypercar, Autocar reports.

The Valhalla concept was initially introduced in 2019, and was supposed to feature a twin-turbo V6 powerplant with a hybrid system, but a lot has changed in the last two years.

Aston Martin plans to introduce a new version of the vehicle in the coming months, for eventual production beginning in the second half of 2023.

Nothing is off limits for the new hypercar, pending the costs associated, aid Aston boss Tobias Moers during the announcement of the company’s 2020 financial results. There has already been significant interest in the Valhalla, with many deposits put down for the upcoming vehicle.

Whatever powertrain the Valhalla gets, it will likely pale in comparison to the one in the upcoming Valkyrie, a 6.5-litre V12 coupled to a hybrid-electric motor. Both vehicles are part of Aston Martin’s plans to electrify 90 per cent of its portfolio by 2030, and more vehicles are set to make the swap.

The DBX is also slated to receive an electric powertrain from Mercedes-Benz, likely paired to the current twin-turbocharged 4.0-litre V8 that’s already installed. The Mercedes S63e pairs this engine with a 134-horsepower electric motor, and if that motivation is to make it to the DBX, it could mean around 800 combined system horsepower.

The DBX will arrive sometime in 2024, while other plug-in hybrid Aston Martin models will be in the works in the meantime.
