Reinvented muscle car enters advanced testing stage; four-wheel-drive hybrid V8 drivetrain on the cards
The Ford Mustang is on the cusp of entering its seventh generation, and prototypes are now wearing the production-spec body ahead of an expected launch next year.
The sports coupé wears one of the longest-running (and historically best-selling) nameplates of any car currently on sale and is set to undergo the most radical reinvention in its 58-year history for its next iteration.
Despite the bulky camouflage worn by this prototype, it’s clear that Ford will seek to evolve, rather than overhaul, the Mustang’s characteristic cab-backward silhouette and muscular design cues.
Visible details include new lights at the front and rear and a sharper front grille, but it will be the changes underneath the skin that most tangibly differentiate the Mk7 Mustang from its predecessor.
As previously reported by Autocar, Ford is expected to bring the Mustang into the electrified era with a new petrol-electric drivetrain centred around its trademark V8 petrol engine.
To be sold alongside the new all-electric Ford Mustang Mach-E SUV, the S650-generation Mustang is expected to retain the current car’s 5.0-litre naturally aspirated Coyote V8, but this time with a pair of electric motors installed for reduced emissions, increased power and zero-emissions running capability.
The new drivetrain layout was alluded to in patent filings in 2017, when launching a hybrid Mustang was a higher priority for Ford than the all-electric Mach-E.
Essentially, the Mustang is set to become four-wheel-drive, with the rear axle powered by the V8 and the two electric motors used to drive the front wheels – either independently in EV mode or alongside the petrol motor in dynamic driving situations.
According to the patent, each of the motors would drive its own wheel through a respective reduction gearbox, forming part of a four-wheel-drive system that would “increase wheel traction with a ground surface on which the vehicle sits to increase acceleration and decrease wheel slippage”.
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.
