Deployment of additional horsepower, which can substitute the present push-to-pass overtake system, will come from the hybrid utilizing electrical energy regenerated beneath braking.

“I’m at all times excited to strive one thing new,” stated Energy. “I’ve been an enormous a part of the testing of the brand new hybrid, working on the Indianapolis Motor Speedway street course with out regeneration energy like we’re working right here.
