Nissan has announced a range of new drivetrains for launch this year, as part of the Nissan Green Program 2010, which main aim is to reduce carbon dioxide emissions. They include new engines, a revised CVT, Idling Stop and Clean Diesel. Eco friendly and efficient cars will now come with the PURE DRIVE brand.
The first PURE DRIVE car is the new March that will be released in Japan this month. Debuting in Geneva 2010, this small car is capable of 26 km/l fuel economy. Under that little hood is the HR12DE 1.2 litre 3-cylinder engine and the next generation XTRONIC CVT.
Developed in pursuit of lighter weight and a smaller size, the HR12DE uses less moving parts and by applying bore circularity machining to the cylinder block, friction has been reduced by 20%. Besides that, adjusting the weight balance of the engine’s rotary shaft also improves noise and vibration, which is equivalent to 4-cylinder engines.
Nissan is one of the prime movers of CVT tech and it now has a new XTRONIC CVT which is 10% smaller and 13% lighter than before, while also achieving a 30% friction reduction – the latter benefits acceleration, noise levels and fuel economy. Its gear ratio of 7.3 (versus a conventional CVT’s 6.0) is the world’s largest. The new gearbox also integrates the Idling Stop system, which Nissan says is smooth enough that the driver will hardly be aware of it working. The engine can be restarted on a slope without sliding backwards
Next up is the M9R Clean Diesel engine that powers the recently facelifted JDM X-Trail. It meets Japan’s post-new long-term regulations, the most stringent emission standards in the world. The M9R utilizes a highly dispersive lean NOx trap (LNT) catalyst, a world’s first.
Perhaps more relevant to us is the HR15DE, which is the world’s first mass-produced 1.5-litre engine with dual injectors (per cylinder). The dual injectors stabilise combustion by reducing the size of the particles sprayed in the form of a mist by approximately 60%. Combined with Continuously Variable valve Timing Control (CVTC), fuel economy has been improved by approximately 4% compared to Nissan’s current 1.5. This engine powers the Juke in Japan.
The final engine is a downsized unit in keeping with Euro trends. The MR16DDT is a 1.6-litre direct injection turbocharged engine (187 bhp/240 Nm) said to have the power of a 2.5-litre with the fuel efficiency of a 1.8-litre. It also comes with dual CVTC and hydrogen-free DLC (Diamond Like Carbon) coating along with new friction-reduced valve springs. This motor will debut in the Juke before the end of this year.

Looking to sell your car? Sell it with Carro.
Looks like the trend is to have a small engine with force induction.
When our ma-campro will get turbo… will miss out the trend soon..
After all, it took almost 4 years to get CPS.
my blm 1.3 saga FC is so crappy that it’s almost matching a 1.8 to 2.0 FC of a japs car. *sigh*
If i not mistaken the 1.2 new engine also have supercharged version!

“Nissan will also offer a supercharged 1.2-litre direct injection iteration with a start-stop system fitted as standard in Europe. These technological innovations – stop-start reduces CO2 by six per cent – combine to offer spirited performance, with outputs of 72kW (98PS) and 142Nm of torque. Emissions will be just 95g/km, an exceptional achievement for a petrol engine.”
26km/l for the NISSAN March. Sure or not? Like that those hybrid cars can close shop already.
fuel economy has been improved by approximately 4% compared to Nissan’s current 1.5
too small improvement actually….,
Wish to have XTRONIC CVT with current latio, it will really bring up the Nissan technology… I gues this is more TCM issue than global Nissan…
Too bad it is TCM…
Kudos to NISSAN…..but TCM really needs to change their thinking & directions. CEFIRO also have change looks d lorrr in outside of MY….still they are deploying the same old version here…
fear not. we are embracing the proton emas where oil consumption won’t be an issue in the next 3-4 years time.
more electric for everybody!!!
And when TNB says “sorry, the subsidized tariffs is too much for us to bear”… so how?
and battery need to be replaced for every 1-2 years… just can imagine how would be the maintenance cost since battery is the main part now!!!
When will it be available in Malaysia? Which model? Nissan Teana perhaps +_+
Good to find out that there’s a better and improved CVT. Would further enhance the confidence of consumers utilizing this technology for their Autos. :)
Small turbocharged or supercharged engines are the way to go. Thanks to the lesson learnt from turbocharging diesel engines in europe. That is why Proton should implement the turbocharging of its small engines with Phoenix project.
Imagine having a mere 1.5cc from 1NZ-FE from the vios, turbocharged it to 160HP, then mate it with a 5 speed autobox or CVT then u can have that engine for the upcoming Camry.
Hmm…..Maybe its good for Nissan to make such a move.
Building new engines and enhancing its quality…….Rather than building on the old ones….
Proton is also slowly coming up for its campro turbo engine…..Its a good move…
But proton needs more than 1.6l engine…Maybe 1.8l, 2.0l engine wif turbos…
I guess they will be enough to power SUV, MPV, or even sports model if they decided to make new models…..
agree..proton very slow..kin nk tgu smpi 40-80thn bru pndai nk buat gearbox sendiri..campro byk tul mslh sma bising(saga blm)..
Great news. Looking forward to the new engines and X-CVT in the future models.
Every one have to learn …see how GM fall…making big engine with high fuel consumption is no longer relevent..even supercar also put in the hybrid tech….and the facts that US citizen also start to feel burden on the high cruel oil price…suer for others..
the engine just use 1 belt. if the air-con compressor jammed, how to move the car?
panggil tow truck jer la untuk kasi jalan..:)
