Default OT: Manual or automatic gearbox? and XC60 opinion...

One gearbox has the odd gears, the other the even. And changing
between say 1st to 2nd is done by swapping the clutches. When the car is
in 2nd gear, the other box has selected 3rd, and the process repeated.
This arrangement can give a virtually seamless power flow under pretty
well all conditions.


A friend of mine remarked how dangerous these were.

Lets suppose you want instant power, with a manual you can anticipate
how long it takes to go from say 3rd to 2nd gear.

On one of these the gearboxes the parallel box will be sitting in 4th
gear, and so has to make the relevant movements to go into second before
operating the clutch. Thus maybe sitting on the wrong side of the road
whilst wanting to pass a slow vehicle for much longer than expected.

This was his take and I confess not to ever having driven one.




You friend is an idiot. ;-)

These boxes can change so quickly that in practice, they can drop gears and
accelerated faster than you could in a manual. No need to press the
clutch, pick a gear, let the clutch out again etc, just stomp the go pedal.
