Indy: Evolution of the Lotus engine

Faced with the lack of performance of the Lotus engine which still powers Simona de Silvestro (HVM Racing), Katherine Legge and Sébastien Bourdais (Dragon Racing), the British engine manufacturer has received the agreement from the organizers of the discipline to make changes. The regulation provides that an engine manufacturer could make changes if the engine showed a power deficit greater than or equal to 2,5%. Simona de Silvestro will test the first evolution next Monday in Mid-Ohio while other modifications will be planned for Toronto (July 6 to 8), Sonoma (August 26 to 28) and Baltimore (September 1 and 2).
