Anorak Corner 1 - Subaru's Symmetrical AWD system

A few days back, I mentioned the purity of Subaru's drivetrain layout, in which the main elements are laid out in line and a boxer engine is used to achieve a low centre of gravity. This photo (click for an enlarged version), taken at the Salon d'Automobile at Geneva a couple of months ago shows Subaru's so-called 'Symmetrical AWD' system in all its glory.

Subaru has been using this set-up for 35 years and takes it very seriously. Diesel engines have had to wait, presumably because Subaru insisted on developing its own boxer diesel (now on its way later this year), rather than buying in, say, an L4 from someone else.
