VW is having a bit of a shocking week, to put it mildly -- and now the car industry is going to find out three things. Have they all been fiddling pollution test results, will miles per gallon results
be the next figures to come under suspicion, and finally, is there actually any trust with consumers to restore in the first place?
Just as when the phone-hacking scandal broke, many of us
in the media had a strong suspicion that it was not going to be limited to just News UK, and the subsequent spread of the investigation to Trinity Mirror titles has proven the point. So it's a
terrible week for VW, but one can only imagine other carmakers are frantically trying to find out if they do the same thing. Do they have software that can make their diesel engines momentarily turn
down pollution levels so tests are passed before the engine switches back to normal and pumps out nitrous oxide that exceeds legal limits?
When cars are sold on emissions and pollutant
figures, it would be hard to imagine that it is only a single VW engine that is under suspicion.
Which brings us neatly on to the question of what regulators will discover now that governments
across Europe have ordered investigations. Will miles per gallon be questioned next as the car manufacturers are put in the dock? If they are, they might as well plead guilty now. Official fuel
efficiency figures are a laughingstock. I don't think there's a single person out there who believes them. The tests are carried out in laboratories, rather than on the road, with the cars tuned and
set up to perform to standards they could never achieve on the road. The cars are light, there's a suspicion that tyres are pumped up to reduce friction, and everything electrical that can be
dispensed with is switched off.
Leave aside questions of how realistic a 90-second jaunt on a rolling road in a laboratory is -- the cars are never tested in a state in which they would ever be
found on the road. Hence, What Car has an entire section on its Web site devoted to giving more realistic
miles per gallon figures. Worryingly, the difference can be as much as 20 miles per gallon between tests on the road and tests in the laboratory.
However, the laboratory test is the laboratory
test -- and so as long as makers cannot prove to have cheated the process, then I would expect a more realistic testing regime will be brought in, but no action will be taken against manufacturers who
did everything they can within the rules to get the best figures possible, no matter how unrealistic they are.
Which brings us to the third point. VW has been vocal about restoring trust. My
question would be, what trust? Have you ever come across an industry where consumer trust, in the finer details at least, has ever been so low? Consumers don't believe fuel efficiency claims, and they
now probably don't believe emissions figures either. Add to that the fact that it's only recently that garages have told you the on-the-road price for a car -- yes, you're being charged to register
the vehicle and have it delivered to the forecourt, and you get an idea of how low the public's perception of carmakers' claims is. Let's not forget that nobody actually trusts the price on the car
anyway. There's always something it doesn't include and there's always some extra "scotch guard" or tougher paint you'll be told you're foolish not to have added, and that's before we get on to
upgrading to satellite navigation and an automatically opening tailgate.
So, to be honest, I love cars and I wouldn't want to be seen as saying there is complete mistrust between the public
and carmakers. Rather, I think it's more like the relationship we have with politicians. We kind of have to trust them on the big, macro issues -- but when it gets down to the nitty gritty, we don't
have full trust in any of them to deliver what they promised when they were after our vote, or selling us a car.
When VW says it wants to regain trust, then, my point would be, what
trust?
