Nissan BladeGlider EV, IDx Freeflow and IDx Nismo at Tokyo Motor Show 2013

Not content with unveiling the Nismo version of its GT-R supercar at the Tokyo Motor Show, Nissan also showed three new concepts covering motorsport style, modern design and their latest dramatic electric vehicle thinking. Time to meet the triangular-shaped, three-seat BladeGlider EV, the denim-seated IDx Freeflow and the stylishly go-faster IDx Nismo. Remember a black Nissan motorsport creation called the DeltaWing that graced the 2012 Le Mans 24?

A look at future Nissan products

The push for fuel economy leadership will heavily influence the look and performance of Nissan's new products for the next three years. The effort will be focused on three primary areas: cutting vehicle weight, improving aerodynamics and reducing friction in the engine and transmission. Those three priorities already can be seen in the 2013 Altima, which went on sale in June with 20 percent better fuel economy than the outgoing model.

Tyre labelling not telling full story

THE NEW TYRE LABELLING scheme to tell drivers how environmentally efficient a tyre performs is not giving the full picture, according to Emissions Analytics. Tests show that at certain speeds, tyres with a lower efficiency rating can perform as well as those with a higher rating. This means drivers could be paying more for higher rated tyres when they would be as well off with a more affordable tyre.
