You misunderstand me - my point is that following the VW revelations there is pressure to make the official tests more realistic by extending the duration and simulating real-world usage rather than the current very artificial test cycle. Also, currently, the same test cycle is applied to all cars - both conventional petrol/diesel and hybrid - this favours hybrid cars because they can do most of the test on battery and do not demonstrate their performance on petrol. If the authorities design a more extensive test cycle and continue to apply the same tests to all cars, then hybrids will suffer worse than petrol cars in the results - at least assuming that the manufacturers of the petrol cars have not been playing VW tricks to cheat the test.anko wrote:Some people use the car outside of its comfort zone. Is that a reason to change the test in such way that it is tested outside its comfort zone? Many of these people would have walked away from the car if it hadn't been for the tax benefits. Maybe the problem is not the car, but the fact that the tax plans only looks at ownership of the car and not at how the car is used.
75 km is on the "knee" of the curve - certainly 19km would be even more favourable, but if the test was doubled to 150km, the figures would be much worse as the balance shifts from EV to petrol. For conventional vehicles, the length of the test is relatively immaterial - once it's warmed up, it will produce the same figures over 500km as it does over 50km. The VW cheating was discovered as a result of independent testing done over significant distances on public roads - if the new "official" tests build upon that and do not make a distinction between hybrids and conventional cars, they could be much more hostile to hybrids.anko wrote:According to the Dutch Automobile Club (ANWB) the average length of a car trip is about 19 km and cars are parked for about 23 hours per day. Ideal for a car like ours. The plug in hybrid fuel consumption is calculated over an imaginary trip of 75 km. This calculation results in 44 gr CO2 / km, where on a trip of 19 km it would be easy to achieve 0. So, I don't see how such a test favours plug-ins.
I'm not insisting on creating anything - just remarking on what some believe is likely to come out of the VW cockup.anko wrote:Why double the length of the "test" if it is already about 3 times longer than the average car trip? I don't understand why you insist on creating a test that makes the car look bad.
According to Wikipedia (so by no means infallible), the European fuel economy test is only 11 km long. The only reason I can see why the PHEV wouldn't give a 'zero' figure is that it includes a brief spell at 120 kph.anko wrote:The plug in hybrid fuel consumption is calculated over an imaginary trip of 75 km.
