The ‘pancake’ motors in this scenario wouldn’t be “rotationally coupled to the engine”, according to the patent filing.
Power would come from an integrated starter-generator (similar to in a conventional mild hybrid drivetrain), which would itself be powered by the V8’s crankshaft, doing away with the need for a weighty and space-consuming traction battery.
Mounting the EV motors directly to opposing sides of the engine’s oil pan would save space, according to the patent filing, and allow for each to operate independently, thereby offering torque-vectoring across the front axle.
A Ford spokesman declined to give further details of the S650 Mustang at this stage but said that the model will continue to form part of Ford’s European product plan.
Last year, Ford ended European sales of the entry-level Mustang Ecoboost, which shared its turbocharged 2.3-litre four-cylinder engine with the Focus ST, due to slow sales.
It remains unclear whether this powerplant could return in conjunction with a hybrid system, but Ford’s patent applies to V-shaped engines.
Given the extent of camouflage still adorning this prototype, a reveal is clearly some way off, but 2022 will be the current Mustang’s seventh year on sale, so a launch some time in 2023 is highly likely.
