The Cadillac GTP race car competing in the IMSA SportsCar Championship and FIA World Endurance Championship is a true technological powerhouse, packing a wealth of cutting-edge performance goodies to help it go wheel-to-wheel with some of the fastest machines on the planet. As expected, some of that technology will eventually make its way from the track to the street. However, the Cadillac GTP race car also incorporates a feature taken from Cadillac’s street cars.
Interestingly, the the Cadillac GTP race car is equipped with the same rear camera mirror as the production Cadillac models. Of course, this feature isn’t to help the Cadillac V-Series.R parallel park, but rather, to help the driver see out the rear of the vehicle for passed traffic and rivals in the GTP class under racing conditions, as a traditional mirror simply wouldn’t work in the tight, bunker-like racing cockpit of the V-Series.R.
As for the powerplant, the Cadillac GTP race car features the LMC55.R cross-plane V8 engine. Output is rated at 670 horsepower. Designed and built by the team at the GM Racing and Performance Center in Pontiac, Michigan, the LMC55.R is the only hybrid, naturally aspirated engine competing in both the IMSA GTP class and WEC Hypercar class. Standout features include 5.5 liters of displacement, 32 valves, dual overhead cams, dry dump lubrication, and a 90-degree cylinder configuration. The engine also serves as a structural component in the race car.
Output is sent rearwards through the Xtrac P1359 seven-speed sequential gearbox, while a rear-mounted 50 kW electric motor provides the extra electron-powered oomph. Vehicle weight is set at 2,380 pounds.
For those fans who may have missed it, the Cadillac GTP race car just secured a second-place finish at the 62nd annual Rolex 24 at Daytona, finishing a mere 2.112 seconds behind the race-winning No. 7 Porsche 963 after 791 laps of racing.
