China cracks the electric car
A Chinese firm says its four-seater battery car can cover 250 miles – a claim that appears to be almost feasible
In the week that General Motors filed for chapter 11 bankruptcy protection, ending a century of global dominance, the centre of gravity of the world’s car industry shifted perceptibly towards China. Here, some of the biggest strides in motor engineering are being made, including one shown to The Sunday Times on an industrial estate in Hangzhou, 90 miles southwest of Shanghai. This is where engineers for New Power have beaten western rivals to achieve what they claim is the first production-ready, all-electric car to offer a range comparable to petrol-powered vehicles.
For years, engineers in Europe, America and Japan have struggled to achieve the perfect balance: a battery that is small and light enough to fit in a family car, yet capable of storing enough energy to keep it going for a practical range between top-ups. The Reva G-Wiz, Britain’s bestselling electric vehicle, has a range of no more than 48 miles between charges; the Smart ED, on trial in the UK, beats it by only 14 miles; and although the electric Mini claims a range of 150 miles, it is only a two-seater (the huge battery taking up the back seat), and BMW has no plans to put it into production.
New Power, by contrast, claims to have developed an electric four-seater with a range of 250 miles and plans to bring it to the UK “within the next couple of years”. Known as the Zhong Tai (the name translates roughly as “peace and safety for the people”), it has lithium-ion batteries that can be recharged in 6-8 hours from a conventional socket, or in two hours from a high-power recharging point. With a top speed of 75mph and an estimated price tag of between £16,300 and £20,500 in Britain, the Zhong Tai could be both practical and affordable enough to make drivers part with their internal combustion engines for good.
The Sunday Times was the first western publication to put New Power’s claims to the test. On first impressions the Zhong Tai looked anything but remarkable. The car’s basic bodywork and chassis are based on a 2006 Daihatsu Terios, a compact 4×4, the licence for which was bought and adapted for Chinese production, originally as a petrol car. The electric version looks identical to a conventional Terios from the outside, with the recharging point where the petrol cap should be and only the absence of an exhaust pipe giving the game away.
The interior feels a little dated but that reflects how much standards of comfort have advanced in the past three years. The dashboard display flashed up speed, distance travelled and the percentage charge left in the batteries — 75% when we first stepped into the car.
At New Power’s spartan headquarters, Mao Zhong, the company’s general manager, outlined how his car could “solve the emissions problems” plaguing both China — where the number of cars is predicted to hit 150m by 2020 — and the rest of the world. On paper, it seems astonishing that such a small operation, with a staff of just 30, should have produced China’s first production-ready all-electric car. But the Zhong Tai has been in development for six years, backed by Zotye, a mainstream car maker, of which New Power is a “green” subsidiary.
Chinese industry has put huge efforts into battery development, a fact that was reinforced last month when Volkswagen said it would be collaborating with BYD, a Chinese manufacturer of lithium-ion batteries, to develop its first hybrid vehicles.
Still, New Power’s claims of a 250-mile range were remarkable so we were intrigued to find out how the vehicle would perform. Tipping the scales at 1.2 tons, the Zhong Tai sounds like a cumbersome beast. Its battery alone weighs about 660lb. It is housed under the car, although in the model I tried, a further auxiliary battery took up a good proportion of the boot space.
The claimed acceleration rate is 0-60mph in 12sec and the car is, indeed, quite spritely. When I pressed hard on the accelerator, the car leapt from 18mph-54mph in just 5sec, but then alarms started screeching and the engine had to be restarted. There was another worry. Accidentally touching the battery in the boot resulted in a mighty electric shock, although the company insisted this was a minor fault and rectified it within minutes.
And what of that all-important 250-mile range? Unfortunately, we couldn’t cover that distance in the time available for the test but by keeping an eye on the charge monitor it was possible to get an idea as to the veracity of New Power’s claims. At the start of the test the car had a three-quarters charge; 120 miles of reasonably hard driving later, it was showing a 42% charge. Assuming the power meter was accurate and proportional, the company’s claim is not unfeasible.
On an open road, at an average speed of 60mph, the car’s range drops to about 170 miles, according to New Power. Reduce average speed to 48mph and the company claims an average range of 218 miles. In “city driving with stops and starts”, the company reckons it can reach its maximum range of about 250 miles.
The Chinese government has announced plans to set up a 10 billion yuan (£890m) fund to promote alternative energy and is offering generous grants towards the production of electric vehicles, stating that all car companies should be producing one green vehicle by 2011.
The Zhong Tai is set to go into production next year, eventually building towards annual production of 20,000 vehicles. Wu Aibing, public relations director for New Power, claims the company is “in conversations about co-operation for overseas distribution” in the UK and US.
The company has been in touch with Electric Village, a London-based marketing company specialising in electric vehicles, about promoting the car in Britain. “The new vehicle is game-changing in the rapidly emerging electric car sector,” says Stewart McKee, the chief executive of Electric Village. “Hence we are looking at a distribution and sales strategy for the UK market.”
Even if New Power’s reliability and range claims hold up under further testing, there are still question marks about the car’s potential success, particularly in foreign markets.
Chinese exports, such as the Jiang-ling Landwind, a large petrol-powered SUV, have failed European safety tests. Aside from safety, the Zhong Tai’s retro looks may not appeal to image-conscious westerners.
However, with most mainstream European car manufacturers putting off electric car production until 2011 or later, and current options offering a range of no more than about 50 miles, this car could lead the way to a practical all-electric automotive future.
