RE: how does an open differential work

[Dave Eaton <dave.eaton@minedu.govt.nz>]

hey, you're on.

btw, power = torque * rotational speed.

if rotational speed is 0, then so is power.  power is what is required...

as for the modern quattro's, then they all have torsen.  they also have edl,
which is also as you suggest, basically an abs backwards...
