Has anyone got any Honda CTDI 2.2 that will actually do anywhere near the official mpg ?.?

Question

I have one of the new Civic 2.2 diesels and am only getting around 40 mpg - some way short of the official claim. My driving is almost entirely in top gear on the mototway at 70-85 mph, with only myself in the vehicle and a couple of briefcases. What does yours do on fuel. The dealer reckons its my driving, but other owners either seem to get very good mpg or very bad mpg, just seems to be the way they are.

Answer 1

Have you checked the manual properly??
All these figures are based on 'rolling roads' in a 'closed ' environment, i.e nothing your likely to come across!! Try 56mph, not much more or less and the mpg will soar.

Answer 2

surely there is no official 75mph mpg is there.
In the good old days you could sit at 80 indicated for a couple of hours and see if it did what the makers said, My old MG Maestro used to do 34 mpg while averageing just on 70 mph judged by the motorway kilometer/100 metre posts when the official figures were 34 at 75, refreshingly honest. Never did get anywhere near the 56mph figures, actually I think it does more the faster you go, certainly it struggles to do 30 on A roads....
Actually I was considering a Civic Diesel as a Rover 400 replacement as it has the same 8.5 sec 0 to 60 as the MG but if it is that bad on fuel well stuff that.

everyone at the dealership isn’t a mechanic. your driving is to blame. all auto makers post the "estimated mpg" which is what you take as what you should get. there tests are done with everything out of the trunk (tire, tools...) no air filter, a small Japanese driver and run a 5gal in the tank until dry at 55mph under perfect conditions. it is all in your driving. your not born with the ability to drive fuel efficient. it is a skill learned. also if you cant afford the diesel than you bought a car too expensive. you could of purchased a 91 geo metro and got 50mpg. some people don’t think about economics of vanity. you do have briefcases so you shouldn’t worry about the cost of diesel and what your car gets anyway.

Answer 4

Very few cars ever achieve the official fuel consumption figure in normal driving, because the EC procedures (Commission Directive 93/116/EC) used to determine the official figure are not that indicative of normal driving.
In particular, the test takes place on a rolling road so the surface is very smooth (less rolling resistance than tarmac) and there is no wind resistance. Also the rates of acceleration are very slow, so even the slowest cars are able to complete the test, but this means that for more powerful cars the rates are unrealistically slow.

Also bear in mind that if your car is very new, it won't achieve the levels of consumption it will after a few thousand miles. Also, your driving style will adapt (probably without you noticing) to the characteristics of your new car the more you drive it, so you will also drive more economically.

However, the Honda 2.2 CDTi engine does seem to be one of the worst in terms of the difference between the official and real-world consumptions.

As a comparison, My Renault Mégane 1.9 dCi has achieved 49.3mpg over 40,000 miles, compared to the official figure of 52.3mpg, and it is still gradually improving.

Answer 5

these have been reported in the press as having no where near the claimed mpg. check websites like auto express / what car (i assume they have one) etc.
