    RS5 break-in reduced power?

    Guest-only advertisement. Register or Log In now!
    I was able to do a back-to-back test drive of an RS5 sportback and S4 today. Both new with minimal miles, both with warm (but not fully to temp) motors. The RS5 barely felt any punchier than the S4. It felt significantly less powerful than the Giulia Quadrifoglio, and certainly not +100 hp over the S4.

    Does the RS5 have some kind of break-in power limiting like M cars used to have? I'd love to know if I really got a head-to-head comparison.

    I test drove an RS5 Sportback on friday and I've also test drove an S5 Sportback. I've never drove an S4 but I definitely felt the difference between the S5 SB and the RS5 SB so I'm not sure why you experience was different. The RS5 Sportback was like a rocket and throws you back the S5 SB pulls you back as well but no where near the same amount of force.

    Wonder if there was something wrong with the RS, then. It was definitely not "throw you back" power, unlike the Alfa (which is bonkers).

    Perhaps it was in a different mode than the S model you drove. It’s been awhile since my test drive and there are so many modes (comfort, sport, dynamic) that I don’t remember all of the details. Depending on the mode affects all sorts of the experience from transmission to exhaust to suspension and many more. Like you, I did a back to back “comparison” between the S5 SB and the RS5 Coupe as the SBs were not available last fall. My big question was the extra power worth $20k and it was so noticeable to me I knew it was after the drive. You should go drive the RS again and make sure your rep changes the different driving modes for you and explains how they work.

    I can confirm without a date the new 2.9L does uncork a good bit after a couple hundred miles of break in. I have driven new ones of the truck and then daily drivers with 3-4k miles and they are two different cars. Don't write it off just yet. :)

    This puts a smile on my face as the car already felt very fast and I was pleased with the performance. If it gets even better then I am definitely in for a treat!

    Before I purchased my RS5, I drove it back-to-back with the S5 coupe. The RS5 was definitely much faster; however, in D or not in Dynamic does have an impact. I tried it out (only with the RS5) to see what it was like and it can easily "feel" less powerful when compared to the S5 depending on throttle input, etc. D and comfort really mute the car. I have never driven in D since purchasing and only occasionally do I put the suspension in Auto from Dynamic (everything else stays in Dynamic).

    I can say with confidence that you were more than likely in the wrong combination of settings. "Comfort" versus "Dynamic" and "D" versus "S", makes all the difference. Coming from a 2018 BMW M4 Competition Pack, I would have never purchased the B9 RS5 if it were not comparable in performance. The Quattro, launch control and acceleration had me sold with regard to performance.

    I was in Auto, Dynamic, and Auto with manual shifting.

    Yes, but you also have to switch the transmission mode from “D” to “S”. You can manually shift in both but you want to be in “S” for the most aggressive gearing. Being in “Dynamic” does not automatically switch the transmission to “S”.

    In my experience, all of the A/S/RS variants feel dead and lifeless in comfort or D on the trans. I never use them... my right foot can add "smoothness".

    I drove an S5 SB and RS5 coupe back to back solo on the same loop. The S5 felt great, but the RS was explosive.

    ^ THIS! I just passed 300 mi and the traction control light flashes at me under hard acceleration. What I was even more surprised with is how effortless it is to get the rear to rotate out.

    Had a chance to drive another RS5 SB today. I made sure everything was in maximum attack mode: full dynamic, transmission in S, engine fully warm. Certainly quicker than the S5 but just not as visceral as I'd hoped. Not quite a perfect analogy but the S5 and RS5 just "pull" (though the RS5 does it harder)--neither "punches." No hating on the RS5--it is a seriously gorgeous and special car. I was just hoping it would drive differently than a tuned S5 for the price differential.

    Does the RS5 function differently from the S5? With the S5, the transmission is always in S if one actively changes the drive mode to Dynamic. It only remains in D when set to Dynamic if the car is in Dynamic mode when it starts because the car is required to default to D mode for the transmission upon being started.

    I do believe the RS5 differs from the S5 in this fashion, as I can recall the transmission being in "D" on Dynamic Mode in both cold and warm start up situations. Perhaps it is programmed to do so for fuel efficiency, as switching from "D" to "S" automatically increases the idle RPM start point.

    For EPA certification purposes, the transmission must always begin in D mode upon starting the car if Audi uses the D mode for the mpg ratings. For the same reason, auto stop/start must also be enabled upon starting the car, as Audi obviously has it enabled for mileage certification. At least with the RS, you don't have to deal with that nuisance.
