Advancements in Electric Vehicle (EV) Transmission Systems

Electric vehicles (EVs) are transforming the automotive industry, and perhaps especially with regards to transmission systems. We’re all used to cars that have gearboxes designed to optimise power and fuel efficiency, but EVs bring a new set of challenges and opportunities.

Some EVs operate with a single-speed transmission, but new multi-speed transmission technologies are being developed to enhance performance, range, and that sought-after, hard-to-define, overall driving experience.

Why Are Transmission Systems Important for EVs?

In the cars we are all used to, transmissions control engine speed, torque, and fuel efficiency. Enter EVs, which rely on electric motors and don’t necessarily need the same complex multi-speed transmissions. Torque can be delivered instantly across a wide RPM range and this means a single-speed transmission sufficient for most day-to-day driving needs.

However, as EVs advance, the demand for more power, extended range, and efficient high-speed driving have driven a need for multi-speed transmission options. These can help the car work across all driving needs, whether city centre driving or motorway, creating a true all-rounder. 

Recent Breakthroughs in EV Transmissions

One key development is Amsted Automotive’s Multi-Speed Shift Technology, this set to debut in 2026. Unlike traditional gearboxes, this technology has been specifically engineered for electric powertrains with a new system designed to allow smoother shifts. The benefit here is not just a better driving experience but also greater fuel efficiency and performance. 

It may be a little while off but it will tackle a key limitation of single-speed EV transmissions:  that they perform best at lower speeds. By introducing a multi-speed system, manufacturers could extend an EV’s range and enhance acceleration while also minimising battery usage. This could also lead to heavier vehicles using EV tech.

What Does This Mean for the Future of EVs?

As EV adoption grows, multi-speed transmissions could become common. Will we quickly see a range of EV vehicles suited for all conditions and driving needs? We will likely know more from 2026 onwards. Watch this space…

At North West Transmissions, we’re excited to follow these innovations and consider how they might shape the future of gearbox and transmission servicing.

As always, staying informed on advancements helps us anticipate new needs for transmission repair and maintenance. Who knows, one day we may be servicing multi-speed transmissions in EVs as routinely as we do traditional gearboxes today.
