GT - as quick as it says?

when im doing 90 in my JTD, it just doesnt feel like it really is going that quick (this is on a private road, obviously!)

seems like it is atleast 5mph slower? it does have 17in rims on

....or is it just handling the speed very well?

That'll be it.

Seriously the diesels are deceptively fast. I assume you're pulling just over 2500 rpm?

Sat Nav (GPS TomTom Go) says that my speedo over-reads by about 3-5 mhp where around the 80+ mph mark. Most cars do have a bit of a difference between speedo and reality.

I find on long journeys I have to use the cruise control all the time as I cannot keep to the speed limit otherwise. Once I slipped up and a stone ship struck the bonnet putting a small dent in it.
I can get carried away listening to my music and the engine noise does not convey the speed you are actually travelling at.

Jon: yes if im doing about 2500 in 6th, think that is about 90 - i felt it was reading about 5mph above what it was actually doing - can the dealer check it on diag kit?

speedometers are allowed to over-read by up to 10% (in the UK) but are not allowed to under-read. As a result most do over-read, it used to always be 10% ish but seems on modern cars to be less, typically 5% ish. Of course most cars are offered on a variety of wheel/tyre sizes which further messes things up.

What I want to know is how you feel so sure it is wrong - do you have a GPS built into your brain or something

i dunno, its just a feelin

the car just doesnt feel like it is doing the speed itself, or relative to other cars

...but it could just be that it is so composed at speed compared to the sloppy old a6 i had before

on a slightly different speed note - have finally managed to get my hands on a tank of ultimate diesel - so waiting for the extra power to arrive.....

Good choice Dan....get some Forte diesel additive too......


Oh, and a re-map.....

My sat nav shows a 3-5mph discrepancy (as per most cars these days I think). I've set the speed limit buizzer to 90 to remind me as it is deceptive. It buzzes me, at a true 86, on a regular basis on the same private test track as you of course!

I'm onto my 2nd tank of ultimate diesel, combined with an oil change 2 weeks ago. I'm definitely noticing an improvement in pace but I can't say whether it's the fuel or the oil.

It's feck loads of fun tho.

thanks ALFA Milano - i thought as much

David: has your done over 2k yet? - ive not noticed any change with the ultimate, but might still be using the last of the standard stuff

....but you are right - just driving to the shops is great! and i cant stop looking out the window at it

I am not sure if I would drive about thinking the sat nav is accurate over the speedo as when I was caught speeding, I clocked the Police saw my speedo which was over and looked at my Sat Nav which was 5mph under my speedo and thought great it won't be so bad, unfortunately the Nip matched my Speedo and I got 3 points

thats a bummer sandys

i dont have sat nav, so hopefully wont fall into that trap

...but i doesnt mean i probably didnt do a ton the other day

My 156 feels slower too until you see the number of cars you're passing

true

no extra zoom yet from the ultimate derv

I think BP say you should run 4 or 5 tankfuls through before you'll notice a difference. My Dad runs BP Ultimate in his V6 Peugeot and noticed an improvement in the pickup and performance and also economy.
