@@Aesthetics622 Jokes on you.....That ford 4.0l v6 is MUCH more reliable than this audi engine, they don't break guides NEARLY as often as these audi do! In fact, many of them last a LONG time before a timing service is required (as long as you change the oil on time). And I say that as an Audi fan (had a 1996 a6 quattro and miss it dearly). They should have stuck with timing BELTS and kept them up front!
It's a smart design and doesn't need as much service as other timing chain or belt designs. It gives the most space for the quattro system and transmission to line up with the front axles and keep the engine as far back as possible.
How is it smart when a part which they know WILL need to be replaced eventually to keep the engine running, literally requires taking the engine out lol
Except its still an Audi so the engine is 20 feet a head of the strut towers and it understeers like a goddamn WRX. And its worse to service.. man this is all copium bro are you okay?
Germans love complexity. Fun fact, even Hitler complained that the tiger tanks engineering was too comlicated and they could make more if they just simplified the design.
