You realize that all/most of Audi AWD cars have a rear power bias, right? (I don't know about the A3, A4/6/7/8, or the avants/SUVs) |

Every other current gen Audi uses a longitudinal engine layout with either quattro V: 40-60 torsen center diff or quattro VI: 40-60 crown center diff. Edit - even the previous B7 S4 used the 40-60 split with quattro V. The main problem was the nose heavy V8 which lead to massive understeer - the B8.5 platform is lighter but really gets bailed out by the rear torque vectoring differential, which combats the natural chassis' tendency to understeer while accelerating - largely due to the weight transfer to the back tires when exiting a corner.

I owned and S4 prior to my E90. It was an absolute beast. It was also great in the snow with the AWD. For me the car was kind of tight interior wise and the S4 is becoming quite dated in its appearance. I did look at Audi again prior to buying my current F30 and I could not get passed the fact that the Audi has not really changed since I owned my 2007 S4. Like I said it was a fun car to drive but for me the BMW is more refined and still powerful as well.

So does DHP still get you upgraded suspension components like springs (probably not since ride height doesn't change), sways and endlinks? Or are we just talking about adjustable dampers? If not, this might explain why I've read complaints of 335ix understeer issues.

The S4 will always be nose heavy. It's just that they have all the electronics and AWD to compensate. The 50:50 weight dist. just feels so much more natural. Also, if you do lose control, it's much easier to manage a well balanced car. I do feel the 335i being a little more nose heavy than the 328i and that little bit is noticeable.

Everything below is from here. Simplistic calculation 328i (NA spec AT) curb weight 3461lb with 50/50 implies F1730.5/R1730.5 335ix (NA spec AT) curb weight 3710lb - assume worst case 249lb front implies weight F1979.5/R1730.5 gives 53.36/46.64 split. Generally, a car with 55/45 is labeled as a "pig" in the weight balance department. The moment of inertia used to generate the yaw dynamics is most important for cornering, so the fact that all that weight is so far forward will definitely negatively affect handling (since I = MR^2).

WeightUnladen 3695(3710) lbWeight distribution, front/rear – Manual Transmission52.2/47.8 % Weight distribution, front/rear -– Automatic Transmission52.6/47.4 % I don't pull enough g through turns at stop lights to care about this and I sure as hell can't afford to race my 335 against your S4 at the track. Also, I am not doing any calculations, but I would guess that your tire setup can make up for a lot. On another note... Is service still included for Audis? It was when I had my S4, but I thought I heard they were discontinuing that. |

My thinking is that a 328i m-sport will handle much better than an S4, even with active torque vectoring. Whereas a 335ix with stock suspension (maybe stiffer dampers) will definitely not outclass the S4 in the handling department. Audi charges $800 for the 50k maintenance package. With a MT, this isn't much more than inspections and oil changes. Wear items are not covered like wipers/brake pads. With a DCT, the transmission flush at 35k runs around $400, so the plan is worth it. The problem with German sports cars are the significant *repairs* needed after the warranty ends. I've read many bad things about both BMW/Audi service dept's giving under 50k maintenance/inspections to the interns who don't know WTF they're doing. Most BMW drivers in the US are leases, so this isn't a concern for them.

s4
Yup, again, my point is that the S4 is a great car, but the BMW ends up being a less costly vehicle to own.
Also, when I turned in my S4, the dealership charged me for the wheel damage to the BBS CH 18s that came on it. I didn't really know they were damaged, but I think the charge was around $700. When I turned in my 335, I knew I had damaged the the wheels and assumed that I would pay for them. They were so bad, I could hear it going down the highway and I didn't get charged. I suppose this is dealer specific more than the manufacturer, but it still added up to one hell of an expensive experience. |

I've never leased a car so I don't know how the buyback works. I do know that Audi financial is not very keen on leasing their cars, so the residual values are horrible. BMW would probably prefer to move you into a new lease rather than quibbling over wheel damage. But that's definitely dealer stuff, not the OEM (similar how it's difficult to get Audi's near invoice). I didn't realize you could get BBS wheels on a factory car, was it CPO or something?
