Are you are talking about 1,5Dci and its 90hv version or what?
If that,90hv version is simple and ok for "normal people" who dont want to be a "truck driver" with lots of gears.
Dont understand that idea,nearly every year more and more gears in manual and automatic transmission.
Why,gasoline costs/mpg and noise as high as 5speed transmission models and who wants to shift up and down all time?
Stange thing is the more power engine has,more gears needed!
If there really are more power&torque more you need less gears!
In 60"s and 70"s even the most powerful USA muscle V8 machines has 2-3 speed automatic(idiotproof) or 3-4 speed manual(simple&strong) and those machines has much more real power&torque than normal 4cylinder diesel/gasoline engines now...and you can drive highest gear in town or highway with low or high rpm...
You who have driven or have one know what iam talking about=)
So,if you want Engine "110" and 6speed,you like shifting up/down or have heavy load and want pay more money of that 6speed.
Lets wait year or two so we get 7speed...and more problems because those transmissions must be as light,small and economical+cheap to made.
You certain have heard those big problems with those modern automatic transmissions,max 100 tkm and thats it.
