Remember !!!error: Indecipherable SUB-paragraph formatting!!! ? Remember what a big hit it was? Why don’t we have one for FWD? I know that FWD is akin to some sort of voodoo magic - for decades people tried all sorts of workarounds to get a FWD setup to work. Everyone from Cord to Cadillac to Audi tried longitudinal mounts with what’s essentially the front half of an AWD setup, resulting in all the complexity and power loss of a RWD setup and kind of defeating the purpose. I know Mini actually had a pretty trick setup with the oil pan to put the diff dead-center for equal-length halfshafts, but apparently that was too expensive and complicated for a real viable affordable car. And then one day Fiat said, fuck it, we’re doing unequal-length half-shafts and apparently it works good enough for daily driving to the point where it’s what every car has now. I want to understand how they get away with that though, or what the big deal is. I went back to !!!error: Indecipherable SUB-paragraph formatting!!! and it doesn’t explain the magic at all. If unequal-length shafts aren’t such a big deal after all why did people go through so much trouble to avoid them until deciding it’s not a problem? Also how does the !!!error: Indecipherable SUB-paragraph formatting!!! ? Is it tacked onto a regular Focus FWD setup or do they go with equal-length shafts? Or is the AWD torque vectoring system smart enough to not need equal-length shafts?

“Be the change you wish to see in the Oppo article feed.”
Why don’t you write it? You seem to have a firm grasp on FWD basics.

Well, it’s turning the engine sideways, and having the transmission output somewhere about the middle with the diff near the middle too. It makes the front wheels pull the car in whatever direction the steering wheel is pointed, as long as there is enough traction.
The thing performance enthusiasts don’t like about FWD is that when you are pushing a car near it’s limits, traction usually becomes an issue. Since you need to both power the vehicle and steer from the same wheels, traction problems are bad.
That’s about it in a nutshell.
edited to add - not all FWD turn the engine sideways, old Cadillac and Oldsmobile V8 versions had a real funky transmission that kept a forward facing engine.

What is this FWD you speak of? You mean wrong wheel drive?

Hey, I remember that guide! Good times. Maybe I could put something together sometime.

Well it’s like a MR2 setup, but the wrong way.

I cover some FF history in my post about why the Mini wasn’t special:

And I will probably make a post about the entire history of front wheel drive in the future.
