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.

Since they are still using a manual with standard ratios (they don't disclose the final drive ratio, however) I'd guess it has a conservative powerband.


You can only guess, and there isn't enough information to come to an educated guess, either.

Of course something this small, boosted so large, isn't going to knock your socks off at 1000rpm but I'm sure its completely usable above 2000RPM if the rev limit is really 7500RPM.


You don't know that. At that low of an RPM the turbo may not be spooled enough to make much boost (which a tiny engine needs to produce torque)

. Otherwise they'd use this opportunity to showcase their CVT technology.


Are they even allowed to use a CVT in their race class? You can't just pick and choose what parts you want to put in a race car. Your hands are tied with regulations.
