The top prototype class has switched to hybrid engines this year to make IMSA the first North American racing series to make the technology upgrade. It was the automakers that wanted to move to hybrid so that their motorsports programs would reflect the direction most have taken for their road cars.
“We are in the transformation, or transition, into the electric world,” said Andreas Roos, head of BMW M Motorsport. “This is the perfect fit to be in parallel between our road car development and our racing. It’s very important that we have a road-car relevance and this is a perfect match.”
The cars make their debut in the twice-round-the-clock Rolex 24 at Daytona, which has been described as a “symphony of sounds” because of the new engines. The hybrid powertrains marry a traditional internal combustion engine with Bosch’s Motor Generation Unit, an energy recovery system that includes batteries and an Xtrac gearbox.
One of the major concerns headed into this new era was that the hybrid technology would rob the cars of the loud roar that is part of motorsports’ allure. But the opposite has happened as the four manufacturers in GTP — double the number from last year — created engines with distinctive sounds. BMW and Porsche both moved up classes to be part of the endeavor, and Lamborghini has announced plans to enter the series.
