Anything that requires the automotive industry to push for renewable engines and resources they need to make a bold, innovative move. A Finland-based company’s in-wheel motor has developed an 845 HP ring-shaped engine and this new development has made resources such as hydrogen look outdated. For a moment, put hydrogen and electric vehicles aside; this engine development is made to shake up the automotive industry. Donut Lab, the EV tech brand, is not just planning on adding another regular EV in that market but sidelining the traditional drivetrain and changing how we perceive power transfer into wheels.
The science behind the 845 HP in-wheel motor—a power like never before
Today’s electric vehicles are designed in a way that their powered motors are found on the rear or front axles of the vehicle. Donut Lab’s in-wheel development has erased all that. Every wheel has a designated motor for itself instead of being powered by one single motor. These motors integrate and by doing so, they produce 845 horsepower (HP) over all four axles.
According to IEEE Spectrum, because their rotor is integrated into the wheel, these in-wheel hub motors have the exciting potential to enhance vehicle packaging and performance while significantly lowering maintenance and moving parts. However, this long-standing automotive objective has not been fulfilled. Furthermore, the engine is ring-shaped, allowing for more space in the chassis.
The motors’ size installed in wheels by Donut Lab
Donut Lab in creating this engine, ensured that the motors were lightweight. According to the business, as per the IEEE Spectrum’s article, its largest supercar-level motor, measuring 53 centimetres, has a 21-inch diameter and weighs a sleek 40 kilograms (88 pounds). Punching a calculator indicates a powerful power-to-weight ratio of 9.6 horsepower per pound or 15.75 kW/kg.
Although Donut’s initial figures may seem optimistic, the company asserts that its output is almost six times that of Lordstown at the same weight. The four-seat Koenigsegg Gemera’s 40-kilogram “Dark Matter” motor, which has a six-phase radial-flux design, produces up to 597 kW (800 horsepower) and 1,250 Nm, giving a power-to-weight ratio of 14.9 kW/kg.
Hydrogen could get outdated by this HP engine
If hydrogen can get close to being obsolete or become obsolete, then this engine is one of the most powerful in-wheel engines that could be a threat to other engines as well. Hydrogen has always been deciphered as the future of the automotive industry and automakers have been working hard to ensure sustainable engines are manufactured with hydrogen as the main source, but it looks like there is a transformation at hand.
Hydrogen has quite a number of issues, from storage to high costs and the lack of infrastructure. Furthermore, there is a lot of energy loss associated with hydrogen. The process of converting it to electricity to power an engine makes it lose almost 50% of its originality, according to sources. Therefore, it is better to work with other automotive alternatives that are more effective and, most importantly, sustainable.
The future speaks of efficiency and performance
Every time, the automotive industry has a chance to witness growth in its innovations. From hydrogen to EVs, and now ring-shaped engines just to make the driving experience enjoyable for customers too, besides the manufacturing part of it. This shift marks a significant point where we can see how many more lightweight engines are taking over the market.
Automakers cannot ignore the green flags associated with this 845 HP electrical vehicle. It is hard to ignore because they are easier to handle than conventional engines. One of the things that has been putting automakers off has been the high production costs, which are associated with hydrogen. Therefore, having an in-wheel motor engine that is cheaper means there is light at the end of the tunnel. As per reports from Topgear, Verge Motorcycles, a Donut Lab partner, already uses these tiny motors. Given the current requirement to enhance payload and decrease total weight in heavy-duty EVs.
