Ο κινητήρας ονομάζεται DIG-T R. Είναι ένας τρικύλινδρος, υπερτροφοδοτούμενος κινητήρας 1.500 κ.εκ. που αποδίδει 400 άλογα και 380 Nm ροπής ενώ ο κόφτης του βρίσκεται στις 7.500 σ.α.λ.
Η μηχανή ζυγίζει μόλις 40 κιλά και σύμφωνα με την Nissan, προσφέρει περισσότερη ισχύ ανά kg από έναν κινητήρα F1. Εκτός από ελαφρύς, είναι και συμπαγής όμως αφού μετρά 400mm στο μήκος, 200mm στο πλάτος και 500mm στο ύψος.
Ο κινητήρας και το αγωνιστικό στο οποίο θα τοποθετηθεί (το ZEOD RC) θα δοκιμαστούν τους επόμενους 4 μήνες έτσι ώστε ο συνδυασμός να είναι έτοιμος για τις 24 ώρες του Le Mans στις 14 Ιουνίου.

NISSAN UNVEILS REVOLUTIONARY PETROL ENGINE TO COMPLEMENT ELECTRIC ZEOD RC POWERPLANT
- 1.5 litre three-cylinder turbo produces 400hp
- Weighs just 40kg; more power per kilo than a Formula 1 engine
- New technical partnership with Total lubricants revealed
LONDON, ENGLAND, Monday, January 27, 2014: Nissan will not only break new ground with the unique electric power plant aboard the Nissan ZEOD RC at Le Mans this year, but the accompanying internal combustion engine is set to revolutionise 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 litre three-cylinder turbo engine will take over.
The incredibly small engine weighs only 40 kilograms (88 pounds) but produces an astonishing 400hp. The base engine is only 500mm tall x 400mm long x 200mm wide (19.68” x 15.74” x 7.78”). While the engine is technically too heavy to take as carry-on luggage on a plane – it would easily fit inside the luggage guides seen at major airports around the world.
Revving to 7,500rpm, the Nissan DIG-T R produces 380Nm 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 focussing 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 maximise 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 LM P1 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 focussing 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.”
After extensive dyno testing, the Nissan ZEOD RC hit the track for the first time last week with both the electric and internal combustion engines in place.
Both the petrol and electric powerplants run through the same five-speed gearbox that transfers power to the ground via Michelin tyres.
“Being chosen by a car manufacturer as a technological partner to achieve a demonstration of innovation, is always a source of pride, especially on this legendary race – 24 Hours of Le Mans. It drives our researchers to find solutions and get the most out of the technical specifications as well as the fuel economy properties that our TOTAL QUARTZ lubricants range provides to all passenger cars,” said Philippe Girard, Scientific Delegate for Total.
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.
