Champion Audi brings their diesel-hybrids to Le Mans
 

Audi bolsters their winning ways with a new set of diesel-hybrids, R18H, to compete this season for the FIA global championship. Le Mans will see these diesel-hybrids battle with Toyota's gas-hybrids. The future of racing will begin with these two manufacturers (pending others) and hopefully translate into our future daily drivers.
AUTO RACING - LE MANS: Audi Set For Hybrid Debut

So, we also get the Toyota hybrid (gasoline/electric?) in this Le Mans. But we lose the Peugeot team...

You can hear it start in EV mode and switch on the gas engine as it exits the pit area.
