I've seen much discussion about it so I'd think it might be useful in someones search.

Gear---Ratio---Km/h/1000rpm

------------------------------------

1st----3.780---7,8

2nd---2.060---14.2

3rd---1.360---21.6

4th---1.030---28.5

5th---0.840---34.9

Final drive: 3.940

These figures come from the original 4x4 launch, those cars had 195/65 R15 wheels though, while newer ones have 205/55 R16 which is equivalent but not exactly equal.

I hope this helps.

cool, these have been quite elusive!

Do we have the RS ones to hand? (I'll go have a look)

ratios for the RS are as follows:

Gear ratios/mph per 000 for RS as follows:

1st = 3.3/6.2

2nd = 1.94/10.5

3rd = 1.31/15.6

4th = 1.03/19.8

5th = 0.84/24.3

Therefore max speed at 7k is

1st = 43

2nd = 74

3rd = 109

4th = 139

5th = 170.1

aha, here we go:

Gear ratios/mph per 000 for RS as follows:

1st = 3.3/6.2

2nd = 1.94/10.5

3rd = 1.31/15.6

4th = 1.03/19.8

5th = 0.84/24.3

(drat, we are now comparing kmh with mph!)

..but I see Jon beat me to it!!

:p

Only 'cos I got an RS, and a low powered one at that (soon to be rectified!)

Any comment Ian?

Ok, to sum it up

-----------4x4-----------__________-------vRS----------------

Gear---Ratio---Km/h/1000rpm____Ratio---Km/h/1000rpm

----------------------------------------------------------------------

1st----3.780---7,8___3.300---10.0

2nd---2.060---14.2___1.940---16.9

3rd---1.360---21.6___1.130---25.1

4th---1.030---28.5___1.030---31.8

5th---0.840---34.9___0.840---39.123

Thats in Km/h

-----------4x4-----------__________-------vRS----------------

Gear---Ratio---Mi/h/1000rpm____Ratio---Mi/h/1000rpm

----------------------------------------------------------------------

1st----3.780---4.9___3.300---6.2

2nd---2.060---8.8___1.940---10.5

3rd---1.360---13.4___1.130---15.6

4th---1.030---17.7___1.030---19.8

5th---0.840---21.6___0.840---24.3

That's in Mi/h

I used 1.61 Mi/Km

Am I the only one here who doesnt understand these? Is there a good site which explains all these things?

Q.

At what RPM is the rev limiter in the 4x4 and RS then?

Limiter in RS is either 7 or 7.2, but being such a good boy I never rev that high

Which bit don't you understand? The ratio? The last column is the maximum speed atainable in each gear and is therefore the most use.

If the vRS is capable of 170mph at maximum warp in fifth, then I assume they're also electronically limited to xxx,mph like my Fabia. When I max-out in fifth, the car is only doing 3500rpm, and I've always felt there is another 20/25mph under the bonnet, by having 1000rpm to spare. Do Jabba overcome this limiting factor when it comes to remapping? I'd be quite interested to know the Fabia gear ratios and what the TDI would be capable of at maximum revs in fifth... (I reckon close to 135/140?)

Well done Otheos

I thought that the 4x4 was about 22.0 mph / 1000 rpm in top - so 21.6 it is !

So Quinten - it means that 4000revs in 5th gear is a true 86.4mph (which is probably about 92 on the speedo allowing for error).

Still don't get it.

5th = 0.84/24.3

And you say at 4000rpm this translates to 86.4mph... How do you work that out?

Q.

Quinten - I drive a 4x4 !!!

OK in the vRS - 24.3 x 4(000)rpm = 97.2 mph true. Probably about 104 on the speedo.

As the 4x4 is shorter geared (21.6 v 24.3) it will accelerate quicker in 5th gear than the vRS (if remapped to the same bhp!) but be revving higher at any given speed - and using a bit more fuel than the vRS.

revving higher, using more fuel, sounds about right!

Ah, lol! Now it makes sense Well, sense in the sense that the calculations make sense... Does that make sense?

Q.

Well, I'm lost - I think I'm in"sensed" about all the formulas and calculations in this thread - now where is that unsubscribe thread button???

ok, simply put...

The 4x4 box is more "sprint" suited, faster launch, more suited to *relatively* low speed work, B roads, rough tracks etc.

The RS box has longer ratios, more suited to higher speeds \ A roads, flowing fast curves etc.

Kinda goes along with the fact that the RS is more suited to fast A roads, and the 4x4 is more suited to B roads.

(note: for the same power output, and in my opinion:D)

I'll second that, but I'll also say that the 4x4 is better in the fast lane of the motorway for leaving people behind ... but it is a bit noisier !

Call me stupid - or a complete and utter non-nerd - but just for me to have a complete picture: how does one get from the second column to the third? What's the formula here?

You have to multiply by the rpm and wheel circumference, Mattijs.

i.e. engine turning at 1000 rpm divided by gear ratio times wheel circumference (in metres) / 1000 to get kilometres, *60 to convert from minutes to hours - gives kph

in words, the engine at 1000 rpm turns the wheels 1000 * times (here gearing ratio is described as a number less than 1). Multiply up by the wheel circumference to give the distance travelled per engine rev. Divide by 1000 to get from metres to kilometres, multiply by 60 to convert from distance travelled per minute to distance travelled per hour.

That's why I keep saying - wheel and tyre sizes affect gearing....

I agree with this as it also applies to short dual carriageway stretches between roundabouts around where I live (M Keynes).

To put things into perspective, I had a very aggressive BMW 330d almost pushing me away from every stop. Now, they have a very good mid-range (due to an awful lot of torque even in standard form) and respectable acceleration (60 in 7.5'ish), but this one could not keep up.

As he was clearly trying hard, I would have expected the cars to be very similar on the road (we went up to 70-ish) but the gearing clearly works in the 4x4's favour for these kind of roads as well, as I kept pulling away.

I would have been either disgusted or disappointed in the BMW and would have had to dig out the price to remap it to 210bhp and 400lb/ft. That BMW 3.0d is an excellent engine.

I'm curious - would y'all like the 6-speed gearbox sitting in the 180hp Leon?

I don't know all its ratios but I do know that 3rd is 1.48 and 5th is 0.93. Now that would result in lots of added wheel torque!

hello, i`m new here and i`m searching for the ratios of the rear diff on the glxi 1.8t 4x4 , is it 21/20 ? same as the golf g60 syncro with 02c box as i think the octavia uses the 02j 5 speed ?
