The Japanese company THK, specializing in linear motion components with rolling contact, has unveiled an innovative electric vehicle prototype at the 2024 Paris Motor Show. This vehicle, named LSR-05, incorporates some of the latest technological advancements developed by the company, showcasing how its precision engineering expertise can transform the future of electric mobility.
The LSR-05 is an evolution of the concept that THK introduced at the 2023 Tokyo Motor Show. While the initial version was more conceptual, the prototype presented in Paris has been significantly refined and features parts that could be used in commercial vehicle production. This represents a major step forward for the company, which has successfully integrated its technology into every aspect of the vehicle, from the electric powertrain to the charging system, suspension, and even the seats.
One of the most remarkable features of the LSR-05 is its innovative seat design. These seats require much less space on the vehicle’s floor compared to traditional seats, significantly improving the efficiency of the interior space. Thanks to a special actuator, the seats offer great maneuverability, allowing for greater flexibility in the cabin layout. This solution not only optimizes comfort but also frees up space for other components or passengers.
Advanced technology in the powertrain and suspension
The THK prototype also stands out for its advanced propulsion system. It uses electric motors in the rear wheels, each delivering 125 HP, working alongside a traditional electric motor that powers the front axle, providing 295 HP. This setup is complemented by a rear-wheel steering system, enhancing the vehicle’s maneuverability and efficiency. The in-wheel motors feature a variable magnetic flux system that includes a high-rigidity ball screw developed by THK. This design is similar to the one used by Dongfeng in its Fengshen E70 model, which is widely regarded as the first passenger vehicle with in-wheel motors.
Another key feature is the active suspension system, equipped with magnetic dampers, which allows for more precise control of the vehicle’s movement. Additionally, the brake-by-wire system and innovative contactless charging system are other standout technologies in the LSR-05. The charging system uses a power transmitter embedded in the ground and a receiver installed in the vehicle, allowing for efficient charging without cables. THK claims that lowering the vehicle’s height during the charging process improves efficiency, enabling the receiver to be smaller and lighter.
A design backed by experience
The design of the LSR-05 was led by SN DESIGN PLATFORM, a Tokyo-based design firm headed by former Nissan design chief Shiro Nakamura. Nakamura is renowned for his work on iconic models like the Nissan Leaf EV and the GT-R sports car. During his time at Nissan, he oversaw the creation of some of the brand’s most important vehicles, and now, with his team, he has contributed to the design of this promising electric prototype.
The LSR-05 is not the only electric vehicle Nakamura has worked on recently. In 2023, SN DESIGN PLATFORM introduced the EV Sport 01, a concept electric sports car designed to showcase the electric motors developed by the Japanese technology company AIM. While AIM has expressed interest in taking the EV Sport 01 to production, THK has not yet confirmed whether the LSR-05 will follow a similar path. However, the company has mentioned that it is working on an even more advanced prototype, the LSR-07, suggesting that this is just the beginning of its foray into the vehiculos electricos market.
