China unveils a strange in-wheel engine: The end of EVs, but not with hydrogen

China has proven to be able to extend the length of days (Three Gorges Dam) or even to produce an alcohol derivative to kill hydrogen.
However, its most unexpected move has been the new in-wheel engine, an alternative to the conventional ones that are placed under the hood, and which is called to destroy the EVs.
Yes, it is paradoxical, as they themselves want to dominate this sector with BYD and Xiaomi, but they seem to have changed their minds.
China has been hiding a secret for years: This engine is not from BYD, not from Xiaomi
This is an inline electric motor by GAC Group that is one of the largest manufacturers of automobiles from China to unveil what is likely to transform the EV market.
This new technology created by GAC Research and Development Department differentiate the automaker’s electric vehicle powertrain design from traditional approaches.
The in-wheel motor also referred to as the wheel hub motor is an electric motor designed to be located right in the wheel of the car.
This design also does away with usual components of the drivetrain including gear boxes, driveshafts and differential, hence making this powertrain system compact.
GAC’s new in-wheel motor showcases several cutting-edge features that set it apart from conventional electric motors:
High-Speed Operation: At its optimum speed, the motor can revolve at an astounding 30,000 rpm, which bests most of the existing electric motors used in present-day electric cars.
Compact Design: The motor itself is rather small and measures only 330 mm in diameter, which makes it fitting to as many wheels’ sizes as possible.
Lightweight Construction: Coming in a lightweight of 16. 8 kg, the motor further lightens the vehicle; thus improving efficien Power Output: However, due to its size, it is able to produce a maximum of 150 kW of power, or approximately 201 bhp.
Extended Range: Higher efficiency of the motor could add up to 50km (31 miles) of an additional range to an electric vehicle, thus tackling one of the biggest challenges of electrification’s range limitations.
Improved Efficiency: The motor features high peak efficiency of 95% which is higher than most traditional electric motors employed in the contemporary EVs.
Production Timeline: As for the in-wheel motors, the firm plans to start the mass production goal by 2025, which can be construed as rather fast progress from the prototype to the product.
