The second generation of the Cube, released in 2002 with a larger interior than the previous model. The combination of angled and curved surfaces was based on the third generation of the March, powered by a 1.4 L I4 engine. The model included the "e4WD" system as an option, which transfers power to the rear wheels when the front wheels spin via a small electric motor on the rear underside of the floor. The electrically powered system allows for reduced drivetrain powerloss when only driving in FWD mode.
A CVT was optional, and was made available in a stretched wheelbase version with seven seats, called the Cube³. With a CVT equipped Cube, the steering wheel button controls and the sport wheel button on the dash panel are located next to the hazard. In mid 2005, the cube had an optional upgrade with the new HR-series 1.5 L engine from the Nissan Tiida.
All cube models have optional extras including an Ion filter for cleaning the air and Nissan's 'smart key' which allows the driver to enter the car without having to use a key. Other options include a sunroof, 12 different styles of front grill and satellite navigation. Other specific models also have different styles of bodykits and fender flares. They come with optional 14 or 15 inch wheels and the Autech version with chrome stylings and a vinyl style of seat covering. Found on Wikipedia.
