Take a good look at the engine above, because this, ladies and gents, is one hell of a machine. Nissan’s revolutionary DiG-T petrol engine displaces just 1.5 litres from three cylinders, weighs 40kg (88 pounds) and produces the same power figure as a 5.0-litre, E39 M5: that’s right, from 1.5 litres, Nissan’s squeezed 400hp.

The car this incredible little engine will power is Nissan’s unique ZEOD (meaning Zero Emissions on Demand) RC Le Mans racer, which will become the first car to complete a lap of the Circuit de la Sarthe (8.47 miles) in electric mode only. The direct injection and downsized petrol engine (500mm tall, 400mm long, 200mm wide) will then power the ZEOD while the race car’s battery (which drives twin electric motors) is replenished using a regenerative braking system you’d find in a Nissan Leaf Nismo RC.
The ZEOD’s petrol engine will power the car up to speeds of around 185mph and is driven through a five-speed gearbox. The engine also produces 280lb/ft torque and revs to 7500rpm.
Darren Cox, Nissan’s Global Motorsport Director said:
“Our aim is to set new standards in efficiency in regards to every aspect of the car – power train, aerodynamics and handling. For the power train we have worked closely with the team at Total to not only reduce friction inside the engine, but within all components of the power train.
“Friction is the enemy of horsepower and tackling that has been one of the efficiency targets we have concentrated on heavily.”
The ZEOD will make its first race appearance at this year’s Le Mans 24 Hours on June 14-15.
the size is impressive, but it makes you wonder how long it would last.. easy for things to fail when they are that thin and lightweight over time...
the power is meh.. there are 1.6L d series civic engines making 2x that power... mind you these arnt daily cars but neither is this thing..
its a step in the right direction though, i hope it encourages other auto makers to go in a more lightweight direction without sacrificing power, its also nice to see some decent power being put out from an auto maker.
lets face it, 6.4L hemi v8 that only makes 475 ish hp.. rubbish.. or even the Bugatti guys making 1000hp with a 8L w16 quad turbo... friends silverado makes 800whp with a 6.7L and a single supercharger.. he could easily up the boost to get 1000hp
just a link of a supra in the 1500hp range.. 3.4L single turbo.. yes racecar but it shows you what a shop on a budget is capable of.. you would expect massive car manufacturers with millions in engine development could maybe do more with their engines
Snails, is that Will's Silverado you're talking about? if it is I remember when that thing was stock or at least close to it, way back when at Cloverdale skatepark

not to hate but its rare to see auto makes really pushing the envelope with their engines
This is a LeMans race car, what they are allowed to do is governed more by rules than anything. Formula 1 1.5L turbos were making around 1300hp in qualifying form, in the mid 80's. That's 30 years ago, without modern computer control or design, metallurgy etc and that was still limited by rules (capped max boost, amongst other things).
These engines are not at all limited by what the manufacturer is physically capable of making, but by the rules for the racing series they are designing them for. (depending on series you are restricted by material, to a set bore/stroke, max fuel flow allowed, max rpms, max boost etc)

Reason: fail
reading comprehension, i was using the hp to compare why everyone is so amazed as its not an amazing number, i even said what f1 cars are capable of..
i was talking about car manufactures in general under performing while things like this are produced
Reading comprehension? Please highlight where you mentioned F1.
I just found it funny how you were seconding guessing a Works LeMans engine design. Asking how long it would last? I'm going to guess the aim is for the whole 24 hour race.
What you wrote was some weird quasi comparison of a purpose built race motor designed to supplement a primarily electric Lemans car, to shop built and stock street cars. That's beyond apples to oranges.

i thought i put it in there because yes im aware of there 1200-1300hp capabilities. my fail
and i wasnt second guessing quality, im saying if this is the direction manufactures start to go im saying that thin lite material may be strong but who knows how it will last in lets say.. 10 years?
and pointed out the ingenuity of this engine and compared it to poorly performing engines based on hp per L
i used this in comparison for the direction auto manufactures should start aiming
the power is meh.. there are 1.6L d series civic engines making 2x that power... mind you these arnt daily cars but neither is this thing.
I agree with most of your points regarding larger displacement engines, but not this.
While true, how much does a built D16 weigh? Even BMW and Renault have created F1 engines that make way more hp (1000+ range) with same or less displacement their weight wasn't nearly this low.
I think the point is not how big the number is, but how usable of a powerband does it provides. A responsive high compression 400whp motor has a wider utility than a low compression big turbo dynoqueen/drag biased monster.
Even if you put the low weight aside, looking at the size of the turbo it's mighty impressive they managed to squeeze 400hp out of it. Likewise, if you take into account the current global shift back toward efficiency, smaller displacement and forced induction (especially with European manufacturers like Audi, Mercedes and BMW) one could even argue that Nissan designed such a motor especially with production cars in mind.
Sure it's very preliminary and has a way to go via racing development and testing, but everything trickles down to the production cars at some stage. I for one think what they've done is awesome.
these engine can be a headache to start like a F1 engine which is seize together when the engine is cold... probably have to feed in warm fluid and air before you can even crank it over..
everybody is posting other cars that make considerably more hp but ppl have to realize if nissan is planning to race this at cirque de la sarthe wouldnt that mean that this car is planning to do a 24 hour race?
id like to see half of the other cars posted drive at 100 percent race and last 24 hours. trhat being said im sure this engine is capable of producing more hp but reliability at 100% power is taken into major consideration.

i posted other cars to show what an independent shop is capable of, and compared this tiny little engines to poorly producing engines such at the 6.4L hemi that dodge produces.. it was a compliment to nissans engine and in hopes that more companies follow suit with the high output low displacement motors and have them eventually land in consumer products
