Engine will power the ZEOD RC hybrid race car
When it comes to racing cars, lighter is always better as long as the components can survive the stresses of racing. In keeping with the “lighter is better” mantra, Nissan has unveiled one of the smallest engines that has ever been used on the racetrack. The new 1.5-liter, 3-cylinder engine will be used to power Nissan’s entry into the 24 Hours of Le Mans this year.
The tiny engine, which is called the DIG-T R, weighs only 88 pounds and uses a turbocharger to develop an impressive 400 hp and 280 pound-feet of torque. The engine produces 4.5 hp per pound giving it a better power to weight ration than the new turbo 1.6L V6 engines that will be used in F1 this year.
The little engine will be used to help power the Nissan ZEOD RC racecar. The drivetrain in the racing car will be able to switch between electric and gas power during the race, with the battery packs charged by regenerative braking.
The engine will be mated to a 5-speed gearbox, which will manage power from both the electric and gas engines.
"Our engine team has done a truly remarkable job with the internal combustion engine," said Darren Cox, Nissan's Global Motorsport Director. "We knew the electric component of the Nissan ZEOD RC was certainly going to turn heads at Le Mans, but our combined zero emission on demand electric/petrol powerplant is quite a stunning piece of engineering.”
According to Nissan, for every hour driven the car will be able to complete a single lap on battery power alone.

F1 engines are not comparable particularly a qualifying engine which could be tuned so high it would only need to last a few laps before failing. What makes the engine in the article impressive is that it will need to be able to run 24 hours flat out and efficiently making the technology a lot more relevant.

Assuming the engine rules haven't changed I believe they are only allowed so many engines in a season (gearboxes too). If they exceed that then their start position is penalized.
Of course the devil is in the details... don't know if they are allowed complete teardowns in between or allowed to fix blocks with windows in them.
