LOTS of problems in the GTP field all week with the spec battery/hybrid unit. Sure hope it doesn't affect anyone in the race. Porsche Penske director said, "we're not sitting here with a warm fuzzy feeling about the race"
They replaced both batteries this afternoon.
Battery/hybrid/torque sensor failures are the most frustrating of all failures. They're spec components and the manufacturers and teams have no control over their performance. Could IMSA follow the WRC and dump the stupid hybrid systems completely? Unlikely.
