Lexus LFA EV to Feature Simulated Sequential Gearbox





Toyota has recently submitted a patent application detailing an innovative method to simulate a manual transmission experience in electric vehicles. This technology is expected to debut in the forthcoming all-electric Lexus LFA, which is scheduled for launch in 2027. This advancement seeks to replicate the tactile feedback of gear shifts without the need for a physical clutch or traditional gears.
Simulated Gear Shifting in Electric Vehicles
The core of this patented system lies in its sophisticated torque management. Instead of mechanical gear changes, the electric motor's torque is precisely controlled to imitate the jolt and engagement felt during sequential shifts in a conventional sports car. The system can momentarily reduce motor torque to zero, then swiftly restore it, even slightly overshooting the target to enhance the sensation of a clutch re-engaging under load. Drivers will have the option to choose from various profiles, such as 'sport' or 'race' modes, which adjust the intensity of these simulated shifts. A 'race' setting, for instance, would deliver a sharper, more aggressive shift feel, while a milder mode would provide a smoother transition suitable for everyday driving.
This pioneering concept addresses the challenges faced by drivers accustomed to automatic transmissions or those new to electric vehicles, who may lack experience with manual shifting. By eliminating the clutch pedal, the system also offers a performance advantage, enabling quicker simulated shifts that closely mirror the rapid responses of a true sequential gearbox on a racetrack. Similar technologies are already being explored and implemented by other manufacturers, with Hyundai's Ioniq 5 N featuring a comparable N e-shift function, and Porsche also holding patents in this domain. Lexus has already teased the inclusion of steering wheel-mounted paddle shifters in its LFA Concept, first showcased at Monterey Car Week and the Japan Mobility Show, reinforcing the likelihood of this technology's integration.
This development signifies an exciting step towards enriching the driving experience of electric sports cars. By blending the raw, engaging feel of a performance vehicle with the advanced capabilities of electric propulsion, Lexus and Toyota are paving the way for EVs that appeal to a broader spectrum of automotive enthusiasts. This innovation could make electric vehicles more appealing to drivers who value the tactile involvement of traditional gear shifting, bridging the sensory gap between past and future automotive technologies.
