German supplier claims to have a "wear-free" electric motor good for pulling, performance-oriented EVs

The German car supplier Mahle has developed an electric motor that, in its own words, sets new standards in the field of sustainability.

The Super Continuous Torque (SCT) motor is “wear-free” and can run continuously at 90% of its maximum power, Mahle said in a press release. This makes it ideal for performance EVs, as well as towing, the company said, adding that the new engine was developed with both passenger cars and commercial vehicles in mind.

This sustainability is achieved with a new integrated oil cooling system, which in addition to performing its primary function ensures that waste heat can be harvested for other uses, Mahle claims.

As with any new piece of hardware, manufacturer claims derived from internal testing are not guaranteed to hold up in the real world. And it’s unclear whether the SCT engine will be equally effective in the many types of vehicles Mahle claims can be used — from performance cars and commercial trucks to construction equipment and tractors.

Mahle has not yet announced any customers for the SCT engine and it could prove to be a tough sale. While many suppliers, such as Yamaha, want to capitalize on the growth in electric vehicle sales by developing engines, most automakers specializing in electric vehicles develop engines in-house rather than buying from suppliers.

While full-line automakers generally buy their engines from suppliers, Rivian stands out as the only one of the automakers who only do EVs — and even that’s due to change.

Tesla, Lucid and Polestar have all developed their own engines. General Motors has that too, but it won’t build them.

Meanwhile, Lordstown stands out as an outlier for being the only company willing to use Elaphe wheel motors in a pickup truck or SUV — in its Endurance pickup truck, under a licensing agreement with the company. That’s something Ford looked into, but ultimately nix for its F-150 Lightning pickup.
