2010 Nissan Fuga/Infiniti M35 Hybrid – Click above for high-res image gallery

Up to this point, Nissan has relied on hybrid technology purchased and licensed from the undisputed leader in hybrid vehicles. That would be Toyota, naturally. But the two Japanese automakers will be moving in separate directions in short order as Nissan has developed its own hybrid powertrain technology, and unlike most other automakers, Nissan's system will debut powering a rear-wheel-drive machine wearing the Infiniti badge.

And there's apparently another way Nissan and Infiniti's first in-house hybrid system will differ from Toyota's full hybrid and Honda's mild hybrid architecture. According to Reuters, Koichi Hayasaki, Nissan's chief engineer of its rear-wheel-drive hybrid system maintains that "Typically, carmakers say the fuel economy improvement on their cars using a 'strong' or 'full' hybrid system is roughly 30 percent, while for 'mild' hybrids, it's 15 percent. We're aiming for an improvement of 60 to 90 percent."

Further, Nissan claims its hybrid system will use a single electric motor and twin clutches (instead of two electric motors as used by Toyota), a move that ought to help make the system simpler and lighter than its competitors. It will also use lithium ion batteries instead of cheaper but less energy dense nickel metal hydride cells. If Nissan can manage to hit all of its targets, we may be looking at a new hybrid standard bearer.

      90% improvement?

      Big whoopee! "Lithium Ion Batteries"! "New Standard For the Industry"

      Seems Hyundai's "blue machines" are all planned to have LIthium Ion batteries. That was announced quite awhile back before Nissan's "break through" lol.

      In fact I believe the Sonata hybrid with Lithium Ion batteries will be out before the Infinity-breakthrough-"new standard" comes out.

        Hyundai uses an even more advanced battery called Lithium POLYMER.

        Lithium ION is 2nd generation tech

        Lithium POLYMER is 3rd generation tech.

        So far, Hyundai is the only manufacturer to have announced a lithium POLYMER battery for production and US consumption.

      They're probably talking city mpg. Most of the new hybrids (Fusion, Sonata) get a >50% boost in city mpg over their 4-cylinder models.

      Looks very similar to the technology used by Hyundai and and VW where an electric motor replaces the torque converter of a regular automatic and is coupled/decoupled to the engine with clutches.

      Raise your hand if you think hybrids are worth the amount over the gas only engine.

        It depends on your priorities. Hybrids may not be my cup of tea, but it's nice to have the option. Choice is good. Now if we could get more affordable diesels, I'd be happy.

      Exciting news if/when it happens and especially if/when pricing is "realistic."

      It will be interesting to see the impact significantly improved fuel economy vehicles will have on the resales of existing cars that even by today's standards might be considered fuel efficient. Even if people want to buy mainstream hybrids (at fair prices), they may have to take a notable loss on their current car due worsening resales of these now "gas hogs" by comparison.

      I got a feeling that this car is going to be really expensive...

      It's a lot easier to make an improvement like that when the cars you start with average 16-20MPG which is what the current Infiniti lineup gets. To improve a G37 that gets 18City on the EPA cycle by 60% you would have to build a new car that gets 29MPG city which shouldn't be all that difficult, especially if you don't mind sacrificing some performance and weight.

      Sweet! Sounds good to me. Now just roll out a hybrid Maxima w/ all wheel drive and I'm sold! :D

      I know it's a luxury car but just how much more money will those more expensive Lithium ion battery packs cost? If it's particularly exorbitant then luxury sedans like the G35 are gonna get too costly for the class and limit this tech to the higher end sedans.
