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.

Is it just the engine block with all the parts that fit inside? It seems hard to believe that it's the entire engine, turbo, intake, exhaust, cooling system, alternator, etc. But maybe a few of those are included in the figure.

Anyway, quite an impressive piece of engineering. I wonder how high it revs, and what kind of de-tuning will be needed for the production version.

Depends on your definition of "entire engine". I do not include things like turbo, intake, exhaust, or cooling system in "entire engine". I would include water and oil pumps however, but even then I think that is being generous to some peoples definition.

Nissan states 7,500 RPM.

If it doesn't include everything the engine needs to make 400hp, then it's misleading.

That being said, I'm fairly sure it doesn't include everything. These claims almost always exclude fluids from the weight calculations, even if they do include all the systems those fluids are needed for.

Ultimately, the only number that really matters is the real world performance of the entire vehicle itself, in it's intended operating environment.

I disagree; where do you draw the line? Gas tank? Fuel lines? Wiring harness? Battery? FPR? Etc Etc
