Depends on:

Gear ratio (usually 1:1 for fourth)
Axle ratio
Max engine revs
Tyre size + pressure

I think precise would indicate he is taking the piss...

You do realise he's taking the piss, right?
80mph max for a mondeo in 5th? Ok...

Advised max speed for a family car in 4th gear would probably be around 50 - 60 mph for a petrol, lower for a diesel I guess...
I would have though 80mph would be ok in most things.
look in the manual and it should say how many revs the car should be doing before changing up. i know that in a vauxhall astra this is 2500 so should be somethng similar in mondeo. you will be able to hear the engine straining if you change too early or late.

thanks for that... however the reason im asking this question is not so that i know when to change gear whilst driving. Its for an assignment im doing.

oh ok. well i guess im pretty relieved tbh.
again i don't know for a mondeo but would say the astra i used to drive (1.6 litre petrol engine fyi) would have been something like:
change 1st to 2nd 10mph
change 2nd to 3rd 25 mph
change 3rd to 4th 35 mph
change 4th to 5th 45 mph

hope this helps a bit. (rep me!)

Why? Maximum speed is the highest revs achievable before the car wont accelerate any further.
So unless we're talking about a tractor or a landrover on the seccond gearbox, then your figures are way off.

An RS6 Avant is a family car, as is a 1.6l Pug 406...

Can do illegal motorway speeds in my car in 4th, why would I want to change to fourth at 40mph when I'm still grinning? :biggrin:

ahhh my bad. thought you meant max speed without damaging the car in the longt-term not literally physical max.
