Who makes the best all wheel drive system?

Porsche.

Anybody with a longitudinal mounted engine sending the majority or all of the power to the rear during normal driving. That's the way the good lord intended it to be. Unfortunately that's getting hard to find these days as everybody is going with a transverse engine and a fwd bias.

>>17498662
I like this picture. Is that a drive shaft sticking out of a transfer case (near passenger flex pipe) ?

>>17498944
yeah but that's only good for hard HECTIC driving, which fucks up your differentials, wheel hubs, wheel bearings, clutch/ flywheel, gear box, and everything else. FWD is inferior for driving, but will last longer, since wear and tear is minimized since it is limited.

>>17498662
what are the tubes between the exhaust pipes in the rear

>>17498662

>>17499099
Fuel send/return pumps

Why is the engine in ahead of the front axle?

What the fuck?

>>17499147
How else do you have a longitudnal AWD setup? Inb4gtr

>>17499147
Becuase Audi.

>>17500249
Insofar As I know BMW doesn't do that shit, their engines are atop the front axle at the very least.

Sure it might set itself on fire and explode, but that's true of all Italian cars.

Question. Are there any AWD/4WD cars (not trucks) with gear selectors like how some offroad vehicles use?

>>17501597
Closest would be an STi with DCCD locked at 50/50.

>>17500317
Came here to say this Ferrari has developed their own awd system and it's superior than all of its competitors

>>17501597
Ferd Escort RS Cosworth

>>17500317
Agreed

>>17498662
Also would like to throw Veyron/Chiron awd system into the ring

>>17498662
Slightly off topic, but wtf with the exhaust? I get the V engine, two downpipes, then individual cats, then the pipes overlap each other and run that way into presumably a resonator, all good, but then instead of splitting off to individual mufflers, the pipes converge in a Y-pipe before splitting off

Wouldn't that create a gas bottleneck? And why go through the trouble of not combining the pipes until the end? Seems like a big waste but I'm not an Audi engineer

>>17501597
Old 4wd subies, hondas, and toyotas had them. Look up 4wd Loyales, Tercels and Civic wagons.

Basically. That thing at the back of the transmission houses a diff, so it's sending power to all four wheels all the time.

>>17501597
I think you could manually lock the center diff on some early AWD Audis.
