RE: Evoque introduces first nine-speed 'box

[RizzoTheRat]

Massey Ferguson. You could get an optional crawler box in it to give you 128 gears over a speed range of +- 22mph

Big thighs.

Yup.

Gets you fit though, it really does. And it adds a massive level of smugness once you've got to the top of the hill........

With a 32 on the front? Ladyboy gear.

I run a 44x16 on my fixed bike!!

Actually, there's been no official confirmation yet on when or whether the Cherokee will get the nine-speed.

Since when has the Cherokee had a transverse engine layout....it's longitudinal surely?

This new 9-speed that the Evoque is getting is a fwd format tranny, not an inline tranny like the 8-speeder in the BMW/Jag etc.

The most common form of CVT is a belt sliding across two conical pulleys to vary the ratio which is indeed utterly pony. Certainly in every application I've tried anyway.

Well it has had it's high and low points.....

Out of interest, what frame is it?

also, how long is your beard and what's your favourite ale?

And when's the fatbike that you've (no doubt) ordered coming?

i don't understand all the negative hype on PH.


the extra mass will be totally negligible

it's actually slightly lighter than the 6 speed!

[kambites]

Daft idea. If you want so many gear ratios, why not just fit a CVT and have done with it?

Exactly. Wouldn't CVT have better served the purpose here?

I'd imagine finding a reliable CVT box which can take a lump of torque and not add in excessive drive train losses is harder than we imagine.

[motoroller]

Why can't they put all this effort into CVTs?

I used to have an Audi A6 2.5 TDi CVT and that was amazing. So smooth to drive, when you need power it was quicker than the more powerful versions and than a manual. Economical too, given that the range of ratios was larger.

[JREwing]

Come on guys, Steve McQueen seemed to have about 17 gears in his Mustang in Bullitt!
Judging by ZF's history, this should be a great box, I'm happy. It has three times as many gears as the first automatic I drove and nearly double as many as the first I owned. Technology.....

Correct me if I'm wrong, but surely numerous manufacturers have done it already? Audi certainly fitted a CVT to some fairly large-engined cars, IIRC.

More gears, it says, mean smaller steps between the ratios

Seriously?!

Wow. Every day is a school day...

well, not necessarily. My mate used to have a DB9 with a 6 speed box (auto) and another friend for example, has a 1.2 seat ibiza with a 5 speed box. every gear in the DB9 is taller, despite having more gears

We're not comparing a super mini to a junior supercar here.. we're considering the same car with a 9spd box vs a 6spd box.

It kinda follows that the 9sp box will have smaller steps between the ratios.. that is unless as another poster pointed out LR were hoping to get the Evoque to 300mph on a salt lake; which, incidentally I know they're not.

9 Gears........? Purely marketing - no technical advantage here at all.

erm, you think you know better?

ok then.

Errrr probably - I did work in F1 and vehicle development for 12 years before moving to the alternative fuels industry. Outside fudging an emissions cycle a bit more, I can't see any advantage here at all, unless they want the Evoque to do 300mph on a salt flat somewhere...?

In auto mode the effect on day-day driving economy is negligible; it'll have an effect on the combined cycle which will slot it into a lower co2 bracket or similar.

The real draw back is anyone wanting to use the car in manual mode with the paddles, you get 'ratio fatigue'... by '6' I've lost interest.

The Multitronic Audis we had really knew how to eat a gearbox. I wouldn't cite it as a good example. It also felt like using an elastic band for propulsion. Stretch, stretch, stretch, pop!

You're running 44:16 off road? Didn't think so, tarmac boy!

Reliable? Check

Can take a lump of torque. 1540nm@ 1400 rpm. check

No more losses than a powershift. check.

Nice one Willy Nilly - And I was just going to say, Fendt Vario lmao

[RizzoTheRat]

The losses on a hydrostatic drive go up with speed though (presumably exponentially with fluid speed?) so while it's no lossier than a conventional gearbox on a tractor, it's not so good on a sports car.

[tomoleeds]

Lets hope its better made than the previous Land rover auto boxs that pack in between 80-110 k
