Even if real world doesn't match the test has been the same for a bit so seeing a 5 year old car getting almost double the mpg is quite amazing.
I guess the research budget is dictated by what is fashionable in the buying market. So whilst Eco is popular I guess the scientists are concentrating more on that area. Certainly seems 200mpg cars are on the way. I suspect that petrol prices will be a little over double what they are now when they are common place. Certainly seems to fit my experience that whilst petrol prices have gone up, my overall spending in petrol has roughly stayed in line with inflation. Here are my rough figures. Seat Ibiza 2002 1.9 tdi, on paper 55 mpg, I get 60, my wife gets 55. Best on a 25 mile commute on mixed roads 84mpg. BMW 123d 2007 2.0, on paper 49 mpg, I get 42 mpg. Not really tried hypermiling tricks with this one yet. The only difference in my driving is the BMW is driven faster on average. I used to try many other 'economical' driving tricks or hypermiling tricks. Oh one more.... Quantum 2+2 2.0 turbo, 40+mpg when driven gently (or on the Ireland trip), 20 odd driven hard.
