Trip computer mpg accurate?

[Smartbear]

:rofl: :rofl: :lol:

I was sub 10 mpg in the Fiat around the ring. Only done Spa in the Zed and didn't work out mpg properly. I was using all 8k for the first few laps, up the main straight, chasing a 996 porker turbo. Then I took pity and started changing into 5th. Still couldn't keep up with my mates 2ltr ford duratec lump though.

What was it in, a caterham 7?

No it was in this. :driving:

That sounded good, obviously forced induction Buzy-do you know how much power it produces?

Fuel economy? You all fail! :lol:
I fail at taking photos however, so it all balances out really

No you fail!!! You need to hand your car keys to a really petrol head. Clearly you're just an old granny oke: :rofl: :rofl:

Not at all! There's a time and a place, so why hoon it on the motorway? It's pointless.
Perfectly happy to waft through a motorway journey, especially here in mainland Europe - set cruise to 65mph, Pink Floyd on the stereo, top down if it's sunny. Arrive at destination eminenty relaxed and maybe a bit more tanned!

Don't get me wrong - I've done my fair share of 'ring shennanigans and I still like to scrub a millimetre or two off the rears on the quiet backroads of Holland but if I'm on the snelweg, with other motorists around, and the Dutch seem to have a particularly aloof driving style I have to say, then why bother driving like a tw@t?

My old Z and a track day :evil:

Obviously using the wrong gears oke:

If we're going into tyres and any old track, then the old Anglesey circuit at 0.9 miles and never out of 3rd would even let the M5 get 10mpg.

Elvington on the other hand was quite good on fuel, but the M5 ate rear tyres when you slide it around too much...

....sorry for the poor quality video, but this was from the days of VHS camcorders and was digitised some time later by Jimbocam on a Bookatrack trackday...

Nice

That looks a whole lot of fun. That's the problem with living in Devon, all the good tracks are miles away.

It was around 400 bhp. But he keeps fettling it. Has a sequential box now too. So faster than it was there. :lol:

Yeah reset it! I reset the mpg every time I fill up and put the mileage, fuel price and litres into an app on my iPhone. I then compare the figures and the car always seems to calculate a bit higher than what I'm actually getting!

Buy a Prius.

NNNNNNooooooooooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Had a new battery in my E86 on 29 December 2016, so all averages were reset then.

I don't use it to commute or in rush hours - also don't use it for short local trips (to avoid parking damage)!

Typical trip is 30+ miles each way using the M3 (50 mph average), M25 (with cameras) then A3 (no cameras, just look out for the vans)!

300 or so miles later my average speed is 37.8 mph and mpg is 31.7 - happy with that!

What I don't know is how accurate the mileage recording is though!

FWIW my 325ti daily (same engine as a pre-facelift 2.5) is showing averages of 31.8 mph and 34.7 mpg after 2 years and 16K miles, and that does do the shopping runs (to save the Z4C)!

Obviously need to try harder. :?

It's more to track the miles I do each year but thanks for the advice..

MOT does that.

I use my 2.5 auto for work and have an app to track journeys for tax reasons, and it has averaged 26.1mpg over the last 810 miles. I can drive on motorways, countryside or town, best tankful was 28mpg, worst 23mpg.

Trouble is, you cannot help sticking your foot down even if it is just for the sound of that engine, and the way it hustles around corners in the country, and the feeling of acceleration and power. If I wanted a car that is good on fuel I would not have got this car.

Hell, in 20 years time we will all be forced to use self drive electric cars, with petrol and diesel cars being limited to 500 miles a year on classic car status and fuel will cost £20,0000 a gallon, we will all be wishing we could go back to thrashing our cars around when it only cost a small amount more. I worked out that it costs me £200 more every 5000 miles to use my Z4 than it does my Santa Fe, which does 35mpg.
