The IndyCar Series takes a step into the racing unknown this weekend at Mid-Ohio as its finally debuts its new electrical hybrid powertrain.
The current 2.2-liter, twin-turbocharged V6 internal combustion engine remains, but is now boosted by a low-voltage (48V) Motor Generator Unit (MGU) via a supercapacitor Energy Storage System (ESS). These have been developed by series engine suppliers Chevrolet and Honda respectively, to deliver on their own desire to add a hybrid element to give it a road-relevant angle.
