IndyCar delays official launch of hybrid to after Indy 500
The 2.2-liter twin turbocharged V-6 engine with hybrid technology was originally planned to be ready for the season-opening Grand Prix of St. Petersburg on March 10th. However, IndyCar has decided to delay its introduction until the second half of the season. Over the past three months, there has been extensive testing of the hybrid power unit, logging 15,256 miles with 13 IndyCar drivers. The partnership between Chevrolet and Honda on this hybrid unit has been exceptional and they are committed to its successful introduction next season. The hybrid power unit will enhance the racing action by providing additional horsepower and more overtaking options for the drivers. The system includes the Motor Generator Unit (MGU) and Energy Storage System (ESS), both fitting inside the bellhousing, and multiple regeneration and deployment strategies have been tested. The hybrid power unit will deploy the additional horsepower through the same motor generator and will not have a restriction on total time usage during a race. Further testing and development will take place throughout the winter and spring months, and the official launch date will be announced later.
