Alpine’s revolutionary plan to introduce in-wheel motors in their upcoming electric sports cars is set to change the game in the automotive industry. Renault Group CEO Luca de Meo has confirmed that the Alpine Performance Platform (APP) will be utilized in the development of up to four different models, including a highly anticipated sports car set to replace the A110.
The use of in-wheel motors offers a myriad of benefits for Alpine as they strive to design a sports car that meets the demands of the modern era. With motors located in the wheels, there is more space available for features such as luggage compartments, footwells, and adjustable seating. This innovative approach allows Alpine to appeal to a wider audience by providing a more spacious interior without compromising on performance.
According to Renault Group design head Laurens van den Acker, the implementation of in-wheel motors has necessitated slight adjustments to the car’s body, including a slight widening. This modification is crucial in accommodating the new technology and optimizing the overall design of the vehicle.
Alpine’s ambitious plans include the release of three to four models based on the APP platform. In addition to the two-seat coupé and roadster, Alpine will introduce a four-seat sports sedan called the A310, which is poised to rival the Porsche Taycan. By utilizing in-wheel motors, Alpine can explore alternative locations for the placement of batteries, deviating from the conventional underfloor positioning that often limits the design of sports cars.
The use of an aluminum platform is projected to reduce the weight of Alpine’s electric sports cars by up to 150-250kg compared to equivalent models. While specific details remain undisclosed, the company is confident that the APP platform will deliver exceptional performance and efficiency.
Renault Group will precede Alpine’s implementation of in-wheel motors with the release of the Renault 5 Turbo 3E, an electric hyper-hatchback featuring two rear-mounted in-wheel motors. This limited-production model is expected to showcase the capabilities of in-wheel motors and the all-aluminum platform developed by Alpine.
In-wheel motors also enable torque vectoring, allowing for individual control of separate wheels to enhance driving dynamics. Alpine has already introduced this technology in the A390 electric crossover, which features two inboard motors at the rear of the vehicle.
While in-wheel motors offer numerous advantages, including increased interior space and enhanced performance, challenges such as additional unsprung weight and potential damage from external forces must be addressed. Despite these obstacles, Alpine remains committed to pushing the boundaries of electric vehicle technology and setting new standards in the industry.
