Was Top Gear Tesla test misleading?

To suggest that Jeremy Clarkson and the Top Gear programme have a flair for the dramatic would rank as one of the understatements of the year – even if it is only January 1. However, a recent review of the Tesla Roadster has led to some serious questions about the show’s methods.

A recent edition of the BBC series featured Mr Clarkson hurtling around the show’s test track in the Roadster only for it to seemingly grind to a halt after a mere 55 miles – much less than the advertised 200 mile battery range.

According to Tesla Motors however, the car did not run out of juice. Instead, the battery charge of the two cars Tesla sent to Top Gear never actually fell below 20 per cent.

Days later a spokeswoman for Top Gear issued a statement claiming that the car was “videotaped being pushed to show what would happen if the Roadster had run out of charge.” The programme stands by its findings according to the BBC.

Tesla RoadsterAccording to Mr Clarkson the show never said the car had run out of power but they calculated it would have run out after 53 miles “but they can’t argue with that because that is a fact.”

In response, a Tesla spokeswoman said that the EPA certified range of the Tesla Roadster was 240 miles but if constantly pushed from 0-60 and running at the top speed of 120mph, then, like any petroleum car, it will have a lower range – although she also said she did not understand how the show calculated 55 (or 53) miles.

Despite this contention, the show was largely positive about the Tesla Roadster and even compared it favourably with the Lotus Elise.

The Tesla is a clever use of light weight Lotus technology to enhance the performance of a reasonable electric propulsion system.
That is all.
It does not come close to a viable part of a new environmentally friendly vehicle system. I do not always agree with Clarkson but on this he is correct. The Tesla, (and any other electric only vehicle) will run out of charge at a distance less than a conventional vehicle, this in itself is not a major problem. The huge disadvantage is that it will then take many hours to recharge, in effect immobilising the vehicle for most of it’s life.
Electricity is not an energy source, it is simply a clean way to convert one energy source into another and it flatters to deceive.
The pollution in making the batteries has to be added to the production of the energy at source and the losses in conversion.
At present the only semi environmentally friendly way to use electric motive power is in mass transportation infra structure’s.
