Nissan unveiled the Hi-Cross Concept hybrid at the 2012 Geneva Motor Show, heralding a possible new design direction for the company as well as a possible expansion of the current Juke-Qashqai-Murano portfolio.

Despite its modest external proportions, Hi-Cross Concept has a space-efficient interior with three rows of seats for seven passengers. The hybrid drivetrain couples an electric motor powered by a Nissan-developed compact lithium-ion battery with a 2.0-liter gasoline direct injection engine to provide the performance potential of a 2.5-liter with the economy and emissions expected from a much smaller unit.

For the concept, the HEV drivetrain is based on new technology developed by Nissan for front-wheel drive models—itself adapted from the hybrid system developed for the RWD Infiniti M35h—but modified to provide four-wheel drive. The new system adopts the “one-motor, two clutch” (1M2CL) technology linked to Nissan’s new generation XTRONIC continuously variable transmission which by itself achieves a 10% improvement in fuel economy over comparable previous generation CVTs. (Earlier post.) The low friction design has smaller shaft-diameter pulleys with a new belt to give the widest possible ratio coverage for enhanced efficiency.

The new FWD hybrid system—which Nissan modified to deliver 4WD for the Hi-Cross Concept—combines an efficient CVT with Nissan’s own one-motor two-clutch system; the engine; and a high-output lithium-ion battery. This earlier rendering of the system uses a 2.5-liter supercharged engine. Click to enlarge.

The 1M2CL system installs the first clutch between the naturally-aspirated 3.5-liter V6 and the electric motor. This clutch allows the full decoupling of the V6 when the systems is in either electric or power regeneration modes, thereby reducing mechanical drag and boosting the efficiency of the electric motor. The second clutch transmits the drive force. (Earlier post.)

The hybrid drivetrain makes extensive use of battery technology developed for the Nissan LEAF. The high output, fast-charging compact lithium-ion battery, linked to high-level motor control technology, provides acceleration assist when needed and permits downsizing of the gasoline engine for optimum economy and emissions.

In city driving, the presence of the electric motor and lithium-ion battery allow the engine to be turned off frequently. It can also be disengaged completely with the clutch, and energy can be recovered effectively when braking.



Every bachelor and single child family must have one or two of these 7-seat units.

Apart from Nuns and Monks everybody buy and consume what they want and can afford and not just what is needed in order to survive. You are no exception. I am sure you use a car if you need to by groceries 5 to 10 miles away. You only need a bike to do so but you use a car and it is not a small car either. I think you can avoid sounding hypocritical by not blaming everyone for extravagancy that can afford a bigger car than yours. Take joy in the fact that this Nissan is a hybrid and therefore it is doing better than most other cars in terms of fuel economics and pollution.

If only the cost of this extravagance was not subsidized by the public at large through polution, taxes, wars, etc.


A supercharger seems overkill, a turbo and the electric motor should be plenty. This is the future of SUVs in a CAFE future.


Freedom of choice is an excellent concept but the real meaning is often twisted my very smart Ads campaigns. The majority is often and unknowingly voting and buying according to what they have been told NOT always for what they really need.

Nobody in their right mind really needed 8000+ lbs Hummer monsters but those of us who were brain washed to drive a bigger vehicle than the neighbor bought them. That is one one of 1001+ examples.

Votes go more and more to the candidates with the most Ads, specially those used to demolish others. We unknowingly sell our votes. That may be one of the reason why almost 50% no longer take the time to vote.


The local paper revealed that 85% of billionaires and millionaires are financially supporting the (R) party at the rate of about $1+B for this year versus as little as 5% who financially support the (D) party. The other 10% could be neutral?

Many would normally find it easy to read between the lines but repeated very expensive negative smart Ads can cloud and dull our mind?

Is $1B from 1% of the population enough to buy the majority of votes?
