Electric cars have long been touted by the media as the saviour of all our climate problems, and by manufacturers as clean, green and very, very efficient – because they want you to buy them!
The Government have even fallen foul enough of this to grant electric cars exemption from road tax and the Congestion Charge, and the perception they’d like to have you is that they produce no polluting emissions whatsoever and that they are built in a wooden shed in the back garden of a hemp-wearing nettle-eater, just to keep the green image alive.
The problem, of course, is that to produce the batteries for these cars the manufacturers have to mine nickel, and then once they have done that they have to ship it three times around the world to a factory which produces so much pollution that vast acres of land around it are decimated. Once that’s done, the battery gets shipped around the world again to a building where it is put in to the car, which is then shipped around the world again to a place where you can buy the thing.
Then you have to charge it up, which means plugging it in to a socket in your house, which is probably receiving its electricity from a coal power station.
And then it runs out of charge before you’ve even driven off your driveway, so you have to charge it back up again.
Of course, manufacturers have had to come up with innovative solutions to get round the fallibilities of the electric motor, most of which require the coupling up of the electric motor to that of a polluting Internal Combustion engine. In order to accelerator hard enough to overtake a snail, or to switch on your air conditioning on a hot day, the electric motor gives way to a petrol engine.
It’s not all bad news, however. Manufacturers have been working on cleaner alternatives for a while. Take the Mercedes BlueTec solution, for example. A small, clean yet incredibly powerful diesel engine with very little emissions appears to mean that you can have an S-Class powered by a measly 1.3 litre engine that runs on nothing more than wee, while other manufacturers are touting hydrogen as the way forward. Very clean and efficient, some are even saying that when it’s parked up the car would be able to use its vast built-in power station to operate your house, but the trouble is that hydrogen is inherently unsafe and ultimately means that we are all going to be driving around in potential mushroom clouds.
But the biggest problem that manufacturers seem to be facing is noise. When a Range Rover V8 bears down on a little old lady crossing the road, the chances are her hearing aids will pick up the sound of the burbling engine and warn her of impending danger. The Tesla Roadster, however, can nip from zero to sixty in a smidge under four seconds and can rocket on to a top speed of 130mph, all without making any more noise than mopping a floor, which means it doesn’t matter how good granny’s hearing aids are, she won’t hear it coming before it kills her.
To get around this problem, electric car manufacturers have decided to fit big speakers that will project the noise of a real engine. The sound will emulate that of a real engine as it speeds up and slows down, giving the driver and passer’s by the perception that it is a real, gas-guzzling behemoth while all the time encouraging trees to grow new leaves.
There are even rumours that drivers will have the option to change the engine noise to emulate whatever car they want. So, owners of a G-Wizz can fool people with the sound of a Ferrari F430 engine, while drivers of a Lightning GT with a strange sense of humour could potentially drive along with the engine noise of a British Leyland Allegro rattling out of their speakers.
All of which got me to thinking, obscurely, about the computer game Sim City. In the game, once you’ve built your city, you can choose to let your denizens live in relative peace and harmony with nothing more to worry about than the fact that you’ve forgotten to build a water supply to their house, or you can switch on Disasters. This, in effect, means the computer will decide – randomly – whether a tornado or an earthquake is going to destroy part of your city, or whether a dinosaur is going to take an afternoon stroll over the power station.
So I find myself wondering if manufacturers of electric cars could build a similar feature in to their playlist. With disasters switched off, owners could simply drive along in relative peace to the dulcet tones of an Aston Martin V8 but, when they’re feeling fruity, they could switch disasters on and the computer could, at any given moment, decide to make it sound like the exhaust had fallen off.
That could give the RAC a few headaches…
It’s all so complicated it makes me glad of my four-litre straight-six.
