Electrical automobiles do not want multi-speed transmissions however, an an effort to recapture a few of the really feel of internal-combustion automobiles, Stellantis is contemplating making single-speed EV transmissions behave like they’ve a number of gears.
America Patent and Trademark Workplace (USPTO) in September printed a Stellantis patent software titled “Simulated Shifts and Modes for Battery Electrical Autos Driving.”
The patent describes adjusting the torque output of motors to simulate the shift factors “of a predetermined typical automotive automated transmission having 4 or extra speeds.” The objective of the patented system is to create a extra concerned driving expertise.
Most manufacturing EVs have single-speed transmissions (the Porsche Taycan being a notable exception with its 2-speed transmission) as a result of they do not want the extra gears. Electrical motors produce most torque at any velocity, so there isn’t any want for various gear ratios to match rpm with wheel velocity.

Nonetheless, Stellantis believes the dearth of shifting “may very well be monotonous or boring to the driving force.” Moreover, the automaker claims within the patent software that simulated shift factors may very well be mixed with programmable drive modes, and even the usage of torque vectoring to set off oversteer or a “crab stroll” operate, with a purpose to create a “extra immersive and enjoyable” driving expertise.
Simulating shift factors additionally would not require a lot extra {hardware}, based on Stellantis. Sensors would inform a management module to briefly alter motor torque output at factors when an precise transmission can be shifting. The patent software discusses simulated power-on upshifts, handbook shifting, and a kick-down detent within the accelerator pedal that will set off a “downshift” when the pedal is pushed previous a sure level, simulating the conduct of automated transmissions.
Stellantis is planning a Dodge electrical muscle automobile, based mostly on the Charger Daytona SRT Idea first proven in 2022. The mannequin is predicted to function the de facto alternative for the present gasoline Charger and Challenger going out of manufacturing this yr. A performance-focused EV like that looks as if match for a brand new function designed to extend driver involvement, however we now know Stellantis goes a distinct route.

Dodge Charger Daytona Idea
A Stellantis spokesperson confirmed to Motor Authority the manufacturing variant of the Charger SRT Daytona Idea will function a multi-speed transmission. Which means actual shift factors, not simulated ones. The transmission is considered one of of three patent-pending applied sciences on the idea which are prone to see their method to a manufacturing automobile, together with the R-Wing aerodynamic entrance wing and Fratzonic Chambered Exhaust sound generator, designed to offer an aural alternative for engine noises.
Different automakers are additionally making an attempt to present EVs a few of the conduct of internal-combustion automobiles to make them extra partaking. The Hyundai Ioniq 5 N has an N e-shift operate that Hyundai mentioned simulates the sensation of an 8-speed dual-clutch automated. Volkswagen has mentioned the ID.GTI electrical scorching hatch idea may be programmed to behave like traditional GTI fashions. Toyota can also be contemplating placing a bodily shifter and clutch pedal in an electrical sports activities automobile, albeit not linked to the driveline.
So whereas there is no such thing as a assure Stellantis’ simulated shifting system will see manufacturing, it is doable that we’ll see this concept resurface in some unspecified time in the future.
