Hydrogen Fuel Cell Cars: The Japanese push

Honda Clarity Hydrogen Fuel Cell Car - already in the real world at $600 a month We make no secret of the fact that we consider Hybrid cars a stop-gap solution to reducing reliance on oil. And frankly, unless you drive like a saint you’ll probably find you get inferior performance and poorer fuel consumption out of regular hybrids than you would from a decent eco-diesel. Only when you start to put complex hybrid systems in high-end cars do you start to come up with something that does mitigate fuel use and improve performance.

Mercedes-Benz Citan

Mercedes-Benz has revealed its new Citan urban delivery van ahead of its public debut at September's IAA Commercial Vehicle Show in Hanover and is the first product of Daimler's partnership with Renault/Nissan. The company's latest model, the first to be designed specifically for the urban environment, will complete the Mercedes-Benz family of vans and is available in a choice of three lengths – Compact (3,940mm), Long (4,320mm) and Extra-long (4,710mm) – and three model variants. The basic version is the panel van, available in all three lengths, with another model being the Citan Mixto with five seats, based on the extra-long version and has a foldable rear bench seat and two sliding doors.

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.
