I agree on the 4.2L.

My first car was a 1968 Mustang, with the 302 V8 (the old 5.0L engine) and I love the rumble of a V8, don't get me wrong. It's perfection to my ear and likely always will be.

Now, that said, I am very anxious to hear what Audi is doing with the rumors around the 4.0 V8. I think this could be a superb engine depending on how they do it. I'm not sure if they are adjusting the bore or stroke on the 4.2, but I hope not. I hope and pray they are taking the 3.0 and adding 2 cylinders (basically), since we have 0.5L per cylinder displacement, making our engine a V8 would keep things light, give a known and proven good bore vs. stroke, balance out the engine more, and allow some incredible things.

The current rumors are that it will debut in the S7 and S8 - the S7 will be like our engine in the A6 and be a detuned version of the exact same engine, while the S8 will get the full tilt version, and be a twin turbo (whoo hoo, FI baby!) The S8 version will output 520HP, and the S7 will be a 394HP version,

Overall it's still just speculation, some sources say the 4.0 will be supercharged (which excites me even more, for why keep reading). This would give more instant torque for one, but mainly it would require a larger blower than we have on the S4 - which is something many S4 enthusiasts and tuners want for our car. If they went with the 1650R, which is not currently in production by Eaton, it would fit the duty the 4.0L would require, but be a boon to get that SC into production in order to allow APR a SC swap out

Whoa! I stand corrected! Wow, I'm a bit surprised. Seeing the TTRS coming stateside isn't real surprising, but figured the real HP beasts would probably be left out. Nice!

That article is from July of 2010... so... lets hope they haven't changed their minds!

BTW- RS5 in white is pure win!

I participated in the Audi Driving Exp in Northern, CA for the S-line cars and found similar experiences with the V8 S5 throwing off the car's balance. I started with the S5 at the beginning of the drive and really questioned my driving abilities because of the difficulties with maintaining the correct balance on the track. I think you really have to be a better driver to handle the S5 correctly on a track like Infineon. The S5 can be very discouraging for an average driver like me.

Once I got into the S4, it was a completely different experience. The balance of the S4 was so much better than the S5 . The car had ample power and stability B8 platform. I was much more confident in the S4 setting into the turns and getting smooth rhythm around the track. I immediately regain my driving confidence and felt like this car is supremely capable on and off the track.

The TTS was also very stable, but lacking in power. I was much more willing to push the TTS and not worry about constantly spinning out or going off track like the S5

They are already availible for pre-order, who was it calling me a downer the other day in email?

Audi should be switching to MY 2012 soon right? Is it still looking like Google/MMI will be coming to the A4/S4 at the refresh time 2013?

Again.. hoping Audi isn't gauging interest on pre-orders! They better bring that car over here! I'm just praying the RS4 happens as well.... and properly. (regardless of whether I buy one or not, it's good for Audi)

The RS5 would be out for me because I need a sedan. If I didn't need four doors, I would have bought an S5 already..

Doubtful I would buy an RS4 as well, since I can dump about $3k into my S4 and have a car with 400+ HP and probably do 90% of the things the RS4 will do.

Watch the TTRS is going to be the real HP beast... Also, it has been tested to run 0-60 in 3.6 and the 1/4 mile in 12.1 @ 113mph With a tune your looking at mid 11's... Unfortunately, we won't be able to get the DSG in the US and the 6-speed is slower... Still tuned it will be a beast...

My Audi dealership has a TTRS in the showroom; and you can spec them on the audi.de website - looks like it has 340HP. I'm assuming it's the same engine as in the RS3 since they have the same HP rating. Not sure I believe a 0-60 run of 3.6 seconds; that's R8 territory and I don't see Audi allowing that.
