CROSSOVER IDEAS FROM NISSAN

A dramatic new concept car from Nissan, to be given its World Premiere at the 2012 Geneva Motor Show, heralds a possible new design direction for the company.

Called the Hi-Cross Concept, the proposal looks at ways to extend Nissan’s leadership of the crossover market with a possible expansion of the current Juke-Qashqai-Murano portfolio. Created in Japan, Hi-Cross Concept is compact yet surprisingly roomy, despite its modest external proportions, it has a highly space efficient interior with three rows of seats for seven passengers. Built on an extensively revised version of Nissan’s Hi-Cross Concept sits on a 2780mm wheelbase. It is 4660mm long, 1850mm wide and 1670mm tall.
Equally as clever is its hybrid drive train, coupling an electric motor – powered by a Nissan-developed compact lithium-ion battery – with a 2.0-litre direct injection petrol engine to provide the performance potential of a 2.5-litre 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, but modified to provide four-wheel drive. The new system’s innovative approach to affordability and packaging adopts ‘one-motor, two clutch’ technology linked to Nissan’s new generation XTRONIC continuously variable transmission which by itself achieves a 10 per cent improvement in fuel economy over comparable previous generation CVTs. The low friction design has smaller shaft-diameter pulleys with a new belt to give the widest possible ratio coverage for enhanced efficiency.
The hybrid drivetrain makes extensive use of battery technology developed for the award-winning 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 petrol engine for optimum economy and emissions.
In city, 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.
