If you take 64mpg and convert to imperial mpg you get 77 imperial mpg, which is much closer to the 80 the car is calculating.

The only other things I can suggest is to speak to other owners see if they are seeing the same difference between the car display and calculated.

Hopefully between us all we can come up with some answers.

P.S. Do you have an instantaneous mpg display? What does this show at a constant 50 mpg, use cruise control if you have it for this test.

Oliver.

But the 64mpg is an imperial fig (4.546 litres per gallon) , so converting it to imperial does not make sense ??
The trip computer is not always that far out - nor is it a constant ... but it IS the most inaccurate one I have ever had ... but that does not worry me overly.
yes - I know of other owner , now also on fuelly , getting and reading similar figs to me.
Accuracy of trip checked against GPS - within a few % ... OK.
The Instantaneous mpg display is 100 % useless (not sure who's bright idea it was !!) , It is a bar display (not digital) which .... wait for it ... reads up to 60mpg maximum !!.
So , assuming you meant 50mph (vs mpg) ... it reads full scale deflection all the time , as it would at 60mph. No cruise control.

I find it better to reset average trip for this sort of comparison , drive say 10 or 15 miles till reading "settles" - the try again (reset all) at a different speed , to make comparisons or whatever it is you are trying to examine. Whilst this does not give an accurate figure - at least the comparisons are relative !

Good thought on the imp / metric / USA dimensions , but I have that covered ... cheers.

Perfect example why i will never buy newer cars. Huge waste.

[Draigflag]

Huge waste of what?

[cburb88]

Time and money. Inability to perform diagnosis and repairs yourself. Loss of money overtime after buying something new. Expensive parts. More parts to go wrong and fail. Higher insurance sometimes since you need full coverage. I could go on and on.

Not sure I agree - this is my first EVER new car.

My "justification" was simple : Saving in fuel costs (at estimated genuine 70mpg) coupled with free Road fund licence (Tax) , was going to save me £1000 per year over our existing car. The car was going to be kept for 10 years (assume worth nothing at end) cost of car was £10,250 .. so in effect car was going to cost me "nothing".

Agree with you on repair and diagnosis of modern cars , BUT a) to have something self fixable ... it really has to be approx 2002 or older ... hmm , is this really what you want ?
b) With this new car , there are 5 years unlimited mileage warranty , and breakdown insurance , and a free annual health check (hook up to Hyundai Computer) .. so very cheap running for at least 5 years , and hopefully all the bugs ironed out ?

Food for thought !

Im with you on that, I love the whole new car experiance, from the look, feel and smell, to polishing an untouched paint finish. My car is costing £2000 less than my previous one, so even factoring in depreciation, it still costs next to nothing, especialy with free tax, servicing and the warranty of course.

How does the road fund tax work in the UK? The older the car, the higher the tax?

[cburb88]

Hopefully its a better deal overseas then here... because here, if you actually know better with how the system works and can work on cars yourself buying an older car saves you tons of money and time, plus the fact that parts are easy to find, replace, not expensive not to mention alot of select older cars are just way more reliable period.

Almost everything new these days is not made of quality, why would car manufactures make something with quality when they can spend far less money and make something just "good enough" but market it right and hype it up to be something its actually not. These days making anything of quality will lose a company money compared to the money they save with making crap.

Regardless of how nice a new car is anyway. These things will never change for the better... Cost of parts. Ease and ability of self maintenance and repair tasks. Resale value ( thats a huge one, soon as a car comes off the lot its worth way less, by the time its payed off you already lost a ton of money by the time you sell or trade in afterwards). Quality of a select number of different parts. The fact that it being new you have no idea what kind of track record or reputation it has since its brand new you arent going to get an idea of how well the car will hold up, compared to older cars there is years and years.

The whole "new car" smell and feel is bleh, id rather make an older car just as nice of shape as a new one if anything then you can have the same feel just better. I also have never re sold a vehicle ive had for less then what i have paid. For example im about to sell a truck i have had for 8 years i paid 650 and im about to sell for 800. For the most part anything newer then late 90s early 2000s i wont own.

It's based on C02 emissions, so the bigger the engine, the more tax you pay. Mine is free as the c02 emissions are less than 100 grams per km. Anything just over 100 grams is £20 a year, then it jumps to £90, £120, £150, etc etc. A Hummer would cost about $600 to $800 a year due to its high emissions, hence why big cars are unpopular.

Yea if it were like that over here alot of people would be screwed. Myself included with my jeep probably.
