New Shape Beetles
Does anyone know what the early new shape Beetles were based on? Was it a Golf platform and running gear? Are the drive shafts equal or unequal
length? Just a silly idea for an alternative classic trials car.

I was about to say it is the Volkswagen Golf 4 platform, as used in quite a few VAG cars. Gremlin beat me to it!
Driveshafts will depend on the engine, my V5 Toledo had unequal driveshafts (from memory the passenger side was significantly shorter). I'm
fairly sure the 1.8 engine was also unequal, and was the most common engine for the quicker cars (in various stages of turbo tune).

Don't most FWD cars have unequal length driveshafts?
The diff is offset with the gearbox so one driveshaft has to make its way across the back of the engine first. IIRC the longer driveshaft is often
supported by a bearing making the CV jointed sections the same length.

The bearing supported shaft is what make it classed as equal length.

So the 'drive shafts' themselves are actually equal length - because 'drive shaft' means - "the bits between the CV
joints" ?
Out of interest - what is the shaft that goes back across the engine called? Is it just part of the output shaft from the diff?
And how come FWD drive shafts aren't called half shafts?!(or is that an American thing?)

I think "driveshaft" refers to the fact it's un-enclosed. Whereas a "halfshaft" is enclosed within the live axle.
I don't know what the "extra" section is referred to - it must have a name though! I do know that some are fitted with balance
weights.
ETA...A Google suggests the "extra" section may be referred to as an "intermediate" shaft.
