The Japanese company is apparently considering the advantages of building an electric supercharger for a production model, trying to patent a more durable and easier to assemble unit.
Since we’re dealing with a patent filling you can be sure there are some pretty technical explanations involved, and has to do with the assembly of the bearing that helps the turbo spin – Toyota wants to employ a coil spring instead of plate springs. It would then be easier to produce and also deliver more consistent pressure, which allows for increased durability and higher performance when spinning occurs at high speeds. The document shows that Toyota’s engineers are at least researching how electric superchargers function. In addition, we can see the development process has been extensive enough for the company craftsmen to consider how they would fabricate everything easier and better.
The United States Patent and Trademark Office only revealed the patent on March 22, 2017 but the Japanese company actually filed it on May 8, 2015 – so there’s a possibility that work has been developed enough to see an application in a production model soon enough. And so we come to the new generation Supra, with numerous reports looking at the possibility of Toyota coming out with an electrified Supra. Audi has been another proponent of electric supercharging, revealing one on the 4.0-liter V8 diesel packing 429 horsepower (320 kilowatts) and 663.8 pound-feet (900 newton meters) in the SQ7 TDI.
