I didn't know that. Makes sense though, it means the diff gears are
constantly rotating in relation to each other but imagine that's no
big deal.

Nor me, I can often see how things work but lack the imagination to
think them up myself.
If you want to get your head around a real chinese puzzle have a look
at the geartrain in one of the hybrids, in essence it's like your for
torque biasing epicyclic but they get it to work as a cvt by applying
load, via an alternator, to one of the outputs. This load then splits
the output from the engine between itself and the wheels via the
torque multiplication effect. The (far lesser) power from the
alternator then either being stored to battery or applied to the
wheels itself in some way that is not apparent to me.
Bank holiday has messed me up, had the old argument with the MOT
station about class 4 MOT and dual purpose, weighbridge didn't open
til 9:30 and now first booking I can get is Friday :-(. I normally
test the 1 month in advance but have been working away.
Incidentally the LR110 with twin 35ltr volume (total 55ltr capacity)
lpg tanks and no spare came in at 1860kg even with some tools and
spare battery.
