Regarding the points about false advertising, etc. by Mitsubishi regarding the potential mpg, surely people should be blaming the official testing authorities for not having a suitable test for hybrid vehicles, rather than blaming Mitsubishi ?
Unless Mitsubishi have somehow cheated the test, or falsified the figures, (which I doubt) then I don’t see what they have done wrong. They performed the official test, achieved 156mpg, so can use this in their advertising. Is that any different from another manufacturer in a ‘normal’ car achieving 55mpg in the test and using that in their advertising, even though in the real world you are unlikely to ever get more than 50 mpg ?
We all know that with a hybrid the mpg can vary massively depending on the nature of driving. On a long motorway journey it might be closer to 35-40, but on a short urban journey it could be infinite mpg. My daily journey (which I would regard as being fairly typical) is a 13 mile commute each way. At this time of year I can do about 20 miles of that on EV, so my mpg for the entire day can easily be above the quoted figure of 156.
If anyone buys a £30k+ car on the strength of seeing one figure in an advert, spends most of their life on the motorway and then complains that they havent achieved 156mpg, then more fool them in my opinion.
