Henry Ford began producing his model T for the masses in 1908. Now comes the environmentally friendly G-Wiz. Keith Johnson, managing director of GoinGreen, began selling the Indian-made "electriCity" car in Britain last summer. Electric cars ar not new, of course. The first electric prototype was built in Scotland way back in the 1830s. Carmakers have been experimenting with electric vehicles ever since, especially in the years following the first oil crisis in 1973.

What makes the G-Wiz different is its ease of use and clever energy management system. Powered by eight 6-volt lead-acid batteries, th micro-coupé can be recharged by plugging it into a standard electric outlet. "It's tried and true technology", says Keith Johnson. To really cut down on greenhouse gases, tough, G-Wiz owners will have to source power from a renewable supply - otherwise, the fact that the G-Wiz produces no emissions will be cancelled by emissions from a polluting power station. While other car manufacturers have concentrated on building a better battery, the Reva Electric Car Co., which manufactures the G-Wiz in Bangalore, has spent seven years developing technologies to make sure its car extracts maximum performance from existing batteries. The G-Wiz has "regenerative braking", for example, which captures friction heat every time the car brakes and converts it into electricity. Body panels of "no-dent plastic" are as lightweight as they are tough.

With a top speed of 64 km/h and a range of just 64 km, the tiny four-seater's appeal is limited. Indeed, London sales have just topped 200, while some 800 cars have been sold in India. The cars sells for $ 13,440 in britain and should be available in parts of Europe by the end of the year. Initial buyers are "classic early adopters", says Johnson : high earners purchasing it as a second or third car for commuting to work. To keep pricing keen, GoinGreen relies entirely on online sales to avoid the expense of a dealership network, and doesn't advertise or print brochures. For buyers, real savings come later. GoinGreen estimates the cost of operating the car is about a penny a mile, the equivalent to 600 m.p.g. Like other electric vehicles, the G-Wiz is also exempt from London's congestion zone charges ($ 9,60 a day, increasing to $15,40 in july), and can park for free on central city streets.

A second-generation G-Wiz, available in early 2006, will hit speeds of around 80 km/h and have a range of 120 km, a jazzy-looking roadster convertible known as the NXG that the company promises will reach speed of 120 km/h and roam for 200 km should follow later in the year. These speeds and range are a big improvement, but still a long way short of petrol- and diesel-driven motors.
