July 1 engineering brief: GEN4 tracks, commercial EV labs, and battery life extension

Good morning. Today's engineering brief is about where electric performance is moving from promise to hardware. We have Formula E preparing tracks and race formats for a much faster GEN4 car, Isuzu opening a dedicated commercial E V development lab in Japan, Renault Trucks stretching long-haul battery use by changing the usable energy window, Cornell researchers trying to repair battery electrodes instead of shredding them, and a large B M W electric S U V that shows how fast high-voltage charging has become normal in heavy passenger vehicles.
