Nissan builds 400 BHP 40 kg three cylinder engine


Nissan has built a 1.5 liter three cylinder turbo gasoline engine that produces 400 horsepower from a 40 kg engine.  That is a better power to weight than a Formula 1 engine.

The engine is destined for Le Mans in Nissan’s electric ZEOD RC but the accompanying internal combustion engine is set to revolutionize standards of performance and efficiency.

The Nissan ZEOD RC will become the first entry at Le Mans to complete a lap of the Circuit de la Sarthe under nothing but electric power in June.  A single lap of each stint (a fuel “stint” lasts approximately one hour) will be electric powered. Then, the new Nissan DIG-T R 1.5 liter three cylinder turbo engine will take over.

The incredibly small engine weighs only 40 kilograms but produces an astonishing 400 horsepower.  The base engine is only 500 mm tall x 400 mm long x 200 mm wide.  Not quite hand luggage, but close!

Revving to 7,500 rpm, the Nissan DIG-T R produces 380 Nm of torque.  At a ratio of 10 horsepower per kilogram, the new engine actually has a better power to weight ratio than the new engines to be used in the FIA Formula 1 World Championship this year.

With the entire concept of the Nissan ZEOD RC focusing heavily on downsizing and efficiency, Nissan turned to new lubricants partner Total to help develop the engine.  The French lubricants manufacturer has worked closely with Nissan engineers to develop fuel and lubricants to maximize the potential of the engine.

The Nissan ZEOD RC will occupy “Garage 56” at this year’s Le Mans 24 Hours, an additional entry reserved by the Automobile Club de l’Ouest for new and ground breaking technologies never previously seen at the classic French endurance event.

Lessons learned from the development of the revolutionary racecar will also be used in the development of Nissan’s planned entry into the LMP 1 class of the FIA World Endurance Championship in 2015.

“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 power plant is quite a stunning piece of engineering.  Nissan will become the first major manufacturer to use a three cylinder engine in major international motorsport.  We’re aiming to maintain our position as industry leaders in focusing on downsizing.  Lessons learned from the development of the engine will be seen in Nissan road cars of the future.  Our aim is to set new standards in efficiency in regards to every aspect of the car: powertrain, aerodynamics and handling.  For the powertrain, we have worked closely with the team at Total to not only reduce friction inside the engine but within all components of the powertrain.  Friction is the enemy of horsepower, and tackling that has been one of the efficiency targets we have concentrated on heavily.”

Both the gasoline and electric power plants run through the same five-speed gearbox that transfers power to the ground via Michelin tires.

The Nissan ZEOD RC will undergo an extensive test program over the next four months prior to it making its race debut at this year’s Le Mans 24 Hours on June 14-15.
