Tata Nano

The front suspension is also independent, by MacPherson struts, and the brakes are all drums because they resist fade efficiently enough in a car that weighs only 600kg, and don’t require a (heavy and costly) power booster, as discs do. The suspension is designed without anti-roll bars, also to save cost and weight.

Evidence of creative cost-saving is everywhere: flat side glass, a single wiper, no tailgate (you load the boot by folding the rear seat flat and loading through one of the big rear doors), no rear wiper, no passenger’s seat adjustment, three wheel-nuts instead of four, one door lock instead of two.

If this sounds too spartan for your tastes, consider the remarkable result: this car literally halves the entry cost of motoring for millions of aspiring Indian motorists. Its price is only about double that of a 150cc Indian-built motorbike. You have to go back 90 years for a parallel in automotive history, when Henry Ford halved the price of the Model T between 1908 and 1918 as he learned how to build it more efficiently.

In India, the cheapest Nano costs £1700, and the most expensive (complete with electric front windows, body-colour bumpers and air conditioning) sets you back around £2300. Four large Europeans easily fit a Nano; Indian owners will doubtless find space for more.

On the road, the Nano is a surprisingly decent proposition. The engine starts with a pleasant thrum, the four-speed gearbox is light and easy to use. Power is meagre, but it’ll shift four big adults well enough to stay with busy traffic in town and cruise at 50-55 mph on the (potholed) open road.

Fuel consumption is highly variable with load and speed, but 55mpg seems an easy average. The steering, not power-assisted, is light enough at parking speeds, and reasonably sharp and the Nano has a spectacularly small turning circle.

It rides well over India’s terrible roads, though it’s a bit bouncy and could do with better pitch-damping because pitching gets rather alarming when the car is fully loaded. There’s body roll, but decent grip considering the small-section tyres, which are differently sized front to rear.

Cornering in the Tata Nano is foolproof and close to neutral despite a 60 per cent rearward weight bias, caused by the fact that the little engine and its ancillaries, including radiator and fuel tank, nestle under the rear seat. The tiny fuel tank of 16 litres gives a 120-mile touring range, and emissions are claimed to be around 20 per cent lower than those of a typical Indian motorbike.

Should I buy one?

You can’t, at least not outside India. But were you in the market, the Nano would be nothing less than a motoring New Deal. It simply doesn’t have a rival, because India’s present entry-level car, the cramped and aged Suzuki Maruti Alto, is nearly double the price.

Nano production is predicted to reach 450,000 when a new plant in the north of India hits its stride in 18 months to two years’ time, at which stage the face of Indian motoring will have altered beyond recognition.
