RE: Evoque introduces first nine-speed 'box
Discussion
I have had the deep, deep displeasure of driving a Nissan with CVT. The experience of putting my foot down and having the engine hit constant high revs as the vehicle steadily accelerates is just very unsatisfying.
I'm no fan of automatics as it is but they are vastly preferable to CVT.

Maybe they should let F1 use a CVT
That would soon get us a decent CVT gearbox
I assume it's been tried and banned? That would soon get us a decent CVT gearbox

Tried not to bite, but it's too hard not too
As has been pointed out, Cherokee is NS so can't use this 9 speed box, and the first 9 speed is at least 2 yrs away, if not 3+
And this is the first j1 application of this box, and indeed any 9 speed EW box, so article is correct. Believe Chrysler have licenced it but as second user

Surely now this is getting daft? Aren't you better off with a well designed, robust CVT type arrangement for this kind of vehicle?
They're becoming more like a CVT when you hear them too. Taking off in an 8 speed 335d the other day, I put my foot down ans thought it was CVT. The rev drop is so small when gear changes come its nearly non existant. CVT used to be criticized due to it keeping the revs up but thats just what these boxes are doing now. As Cookie says, I think it would be easier to jst go for one. They are much more space, weight and fuel efficient after all.I had a rental with a 3 speed auto, which was utterly hilarious. Kickdown took the best part of a second, and the gap between 3rd and 2nd was immense.
Having lots of gears on an autobox that can block shift means that it can get a lot closer to the sweet spot in terms of acceleration and economy for any given throttle opening and speed. No bad thing at all.
Automatic gearboxes were left behind a little because they were fitted to cars for people that didn't like driving. But the rise of DSG spurred on people like ZF and BorgWarner to do some product development, and as it turns out the old slushbox has quite a lot of stuff going for it - like very nice urban driving characteristics, smooth shifting as a matter of course, and very robust torque handling.

Takes me back to my '63 Falcon XL with the 2 speed auto known as Fordomatic. Now that was crude, even in 1968! It was also quite a culture shock as until then I had mainly owned small sports cars, but interestingly I became a lifelong convert to auto boxes for daily drivers.
