All this posting and no Saabs??? You guys are slipping..
Saab 99 engine/drivetrains:
The transmission housing is actually the oil pan as well.
Benefits of this design?.. Well, I imagine that you could fit larger engines as opposed to a transverse FWD. Also has the advantage of equal length drive shafts, something my modern 9-3 is sorely lacking, so it would have no problems with torque steer. I imagine there would be some slight benefits to weight distribution as well considering more of the engine will be behind the front axle, although the centre of gravity might be a bit higher with this configuration..
Longitudinal Boxer 4 is sounding like an interesting idea about now
If this were to be lmplemented in Automation it would be nice to be able to slant the inline engines as they did in the Saabs.. or perhaps slanted by default for Inline engines as the engine would likely be too high to clear the hood..
