If I was in the market for new wheels, I suppose I'd be pleased that Indian car manufacturer TATA (which includes South Africa as one of its markets) is planning to release the world's cheapest car. Just as the original Volkswagen Beetle was developed to provide transportation for the masses, the new 'People's Car' is expected to be cheap enough to achieve the same objective in India. It's expected to sell for £1,200.
This is bad news: not good for the energy crunch, or carbon emissions, or urban life in general. We don't need more cars on the roads, we need fewer. And those that are on the roads must be more efficient. One of the biggest problems with vehicle emissions is that cars are so darn heavy. Most of the energy they use is to propel the car, not the people inside. I haven't seen the numbers, but at a guess I would say that if you could reduce car weight by 50%, you would probably use less fuel than the current generation of hybrids.
Enter Hyundai, whose QuarmaQ concept car uses new materials and manufacturing methods to reduce weight. If you read the details, though, you'll see that the weight reduction is a measly 60kg - the equivalent of one passenger. Hardly a big deal, but credit for trying. They have also replaced some toxic materials with more benign ones, and one QarmaQ re-uses approximately 900 PET bottles that would otherwise become landfill.
The next stage would be to replace the plastic panels with biodegradable panels: now that would be environmentally responsible. It probably wouldn't be any lighter, but it could still be greener. After all, a big part of the environmental impact of a car is not its emissions from driving, but the emissions generated in its manufacture, the space it takes up in landfill sites, and the toxic chemicals left behind. Imagine a car made from modified corn starch - if you damage a panel in a collision, just unbolt it, stick on a new one, and throw the damaged one onto the compost pile.
I am not making this up - the Mini-Bimoke uses biodegradable panels impregnated with palm tree seeds. And there's a new tyre manufacturing technology from Yokohama that enables them to make tyres from orange rinds.
