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.

That and it won't shatter when it breaks destroying the engine.

And how is a Kevlar (or similar) timing belt a bad thing? It's not uncommon on many cars, including Subaru rally cars.

Most cars today utilize rubber in their timing belts. Less valve train harmonics and they keep accurate timing.

You do understand that the synthetic rubber belts are far more reliable from a stretch perspective. When you need dead on accurate timing steel just won't cut it as it is far more likely to stretch/distort.

Let me guess you had a 1980 civic mess up the heads because of the synthetic belt, and now you just ignorantly hate them. Even though they have a scheduled maintenance that you most likely ignored.

Depends on the engine some get damaged by the timing belt breaking and some don't. Either way it shouldn't happen with proper maintenance.

Honda and Mitsubishi has been using Rubber timing belts for a long time. Some of those cars even have 800+ Bhp.
