I finally tested all the drive modes in my stock 2020 C43 with Michelin PS4S tires. For those that are wondering, here are my results without brake boosting or launching in any way and also in full auto. I just floor the pedal from a dead stop:

• Comfort: 0-60 in 4.45s | 1/4mi in 12.85s
• Sport: 0-60 in 4.46s | 1/4mi in 12.88s
• Sport+: 0-60 in 4.45s | 1/4mi in 12.90s
• Reduced: 0-60 in 5.22s | 1/4mi in 14.15s

Did all of these after warming up my car with a 8 mile drive. Current temperature was at 58 degrees and elevation at 1,604ft.

Aside from Reduced mode, it seems like the rest of the drive modes performed the exact same. In terms of feel, I felt the most push in Comfort.

Nice, exactly what the brouchure said. What did you use to capture the numbers? In car, draggy?

zibby43

Very nice numbers.

What did you use as your timing method?

Ramsino

Yes, I used Dragy.

Im surprised comfort and S+ had the same time. I would have expected comfort to be faster.

What mode was the suspension in for all the runs, and were they back to back, or was there a cool off period between?

I personally wasn’t surprised that comfort, sport and sport+ had similar times because when going for best acceleration times he would have been on full throttle anyway, so none of the pedal profiles in the three modes would differ much I guess. Reduced on the other hand would be for poor grip conditions and traction purposes I guess?

You most likely felt the "push" in comfort as you had softest suspension, so you felt the rock.

I'm a little surprised as I thought shifts may be slower than in sport. Even at full throttle, I would have thought in comfort they'd soften shifts

Ramsino

I don't think they soften the shifts in comfort but they actually faked more of a recoil when in Sport+. With the pedal floored, the shifts don't really feel slower than Sport+ at all, albeit the jerky sensation in Sport+ makes it feel more snappy.

Ramsino

I read somewhere that Reduced mode actually forces the engine to not go all out, but not sure if that is true. However, the feel and the slower time in Reduced mode definitely says something. I definitely felt less torque and less power top end in Reduced; just not sure exactly what it does to make the car slower.

Ramsino

The suspension was in whatever the mode the drive mode defaulted to, I did not mess with the suspension manually or anything. I didn't exactly do them back to back but it was pretty close with maybe 2-3 minutes in between as u-turn back to the start so that I could always start at the same exact location, altitude and slope.

Thanks for sharing...never would have guessed that the 3 modes would net the same times...i guess the flat out pedal negates the individual profiles characteristics. Reduced makes sense given its recommended use in slippery conditions.

would be interesting to see what would be faster if you had to pedal the car (highly unlikely with the 4matic) but think that sport+ would net a faster time since it will hold the rpm/gear vs. Potentially upshifting when you lift.

Comfort mode probably has more squat which results in better launching conditions for our RWD-biased vehicles. IIRC, owners who drag their cars recommended to brake boost and set suspension on softest settings for this reason.

ItalianJoe1

Full throttle in comfort or sport or sport+ is all the same. Only differences are how it behaves up to full throttle, does it hold gears, does it downshift early, shift speed, etc. All that is out the window once you are at max desired acceleration, regardless of mode. Except for the reduced mode obviously, but that is literally electing to have less power.

Ramsino

I can imagine that it would make a difference when brake boosting, but I guess flooring the pedal from a stop results in somewhat of a turbo lag so by the time the boost kicks in, the car is already moving so the suspension in comfort didn't really have a chance to load up on the rear.

jonathan358

I'm sure the engine alone can provide enough torque to pitch the car enough for a squatting effect to occur even if minuscule. Every little bit counts I guess?

It just doesn't make sense as to why Sport+ would have same acceleration as Comfort given that it is theoretically supposed to shift faster, hold revs higher, ect. -- even during kickdown.

Boostman76

makes sense

Good thread. Thanks man. Was this with T/C off?

Ramsino

This was just whatever the default is when I turned on the car, so I did not manually change anything, including the traction control. In Sport+ it did use the Sport traction control though.
