EU Car Makers Manipulating Fuel Efficiency Figures
pev writes with a report in The Guardian that "European car manufacturers are rigging fuel efficiency tests by stripping down car interiors, over inflating tyres, taping over panel gaps and generally cheating. This overestimates the figures by 25% to 50%. One would have thought that a simple clause stating that cars have to be tested in the conditions that they are sold in would have been obvious?"
I'm continually amazed at how much more effort and creativity people seem to put into shortcuts to money and various get rich quick schemes, rather than boring, honest work.
Suit A:"We're losing money and marketshare! What are we going to do"
Suit B: "The same thing we do every time"
Both in unison: "Layoffs and hire some more lobbyists!"
Optimistic? I think the word you meant was 'bullshit'. There is a difference between something that may be possible under 100% perfect conditions (yet nearly 100% unlikely in real-world conditions)... and something that has been completely rigged in such ways that even in perfect theoretical conditions it is impossible for the car, unmodified and straight from the factory, to ever come close to such manipulated stats.
This is worse than controlled, theoretical lab tests... this is downright crooked. There is absolutely nothing 'optimistic' about it. This is fraud.
It's actually the opposite. Gaining 10mpg over 40mpg is pathetically little, while gaining 5mpg over 20mpg is HUGE. Dropping 0.5L per 100km is the same amount of saved fuel regardless of if you have a 7L/100km or 3.5L/100km car. Thus it's easy to hype your 30, 35mpg cars and tell people they need to upgrade their 28mpg car, when really that's a huge fucking waste.
The real world effect is that Americans think what we need is shiny new expensive 40mpg hybrids, when the best thing we could do is get the existing 15mpg old-ass broken down shitheaps off the road in exchange for newer 22mpg used cars that exist already. The environmental savings would be bigger than if we just replaced the natural new flow of new cars with a natural new flow of new cars with slightly better mileage. i.e. what's important is the flow of average-mileage used cars into the hands of people who aren't going to buy a new car!

Over inflating tires is dangerous. The whole idea of the correct tire pressure is to give you the full width of the tire to grip the road. If you over inflate, the tire might not blow, but your stopping distance when having to do an emergency stop, will increase dramatically. The exact amount of grip you lose will also make you lose control in corners much quicker.
