One other reason may be that the C63s especially seems to make huge power early, ~3.5-4k and almost feels like it's losing power from there to the redline. The power band in the M5 is almost perfectly linear.

That is my perception. I have had the car for awhile now - since last August - and I have tested this car in most ways. No car is perfect - but I do feel the powerband is quite linear. I don’t feel any dips - especially approaching redline (where I would agree power is strongest). Even lag - in S+ - is pretty minimal.

The reviewers found a perceptible lag in the GT63S however (as did I) - but it did feel stronger from low end hits.

To the other poster - FloridaM5 - I agree with you - Perception is key for most - as you are driving it - and if you are not quantifying that “feeling” via Dragy - you may be disappointed despite being the quicker car.

That said - if you don’t like the way the car drives - regardless of its performance - you have bought the wrong car lol.

I don't think anyone said anything about not liking the performance of the car, so yes, we agree again. It is clear you love the m5!!! I do too..it's a cool ride for sure.

Believe me - I am the least biased person when it comes to cars I own. I have trashed many of them - posting can make that less apparent I agree lol.

The only reason I felt the need to post - is because of the two cars mentioned - the C63S (which is more understandable from a performance comparison perspective) - and the M340i (which is not).

I was more interested to better understand the OP’s experiences.

The F90 is a great platform - it isn’t perfect - but it is solid. For what it is (I have run a 10.87 at almost 130 MPH) - it is fairly quick.

Great times to live in as a car enthusiast!

Right on man. I enjoy reading your thoughts and experiences for that reason....you have driven the crap out of some cars. My intention was just to make sure op didn't give up on the m5 because it doesn't drive/feel like a biturbo amg...and it doesn't. I almost didn't make the change, but I'm super impressed with the car now. My e63s, even with hybrid turbos, had a top end that was only a couple mph better in the 1/4 over my racechip base m5. ET-wise and 1/8 mile-wise, amg all day. When I first got the m5, I was driving it around like it was my amg..and that made it feel slow, and actually be slow. Now that I've figured out this car, its fast, not faster yet, but it's friggin fast. It's the complete package. . Beers on me bud.

As the guys have said, make sure everything is in sport plus and make sure you put your foot right down hard. Right to the floor and hard/quickly. If you don't you wont get the double at least kickdown and the thump in the back. Go and try it again buddy....lol

^^Full agreement and thank-you...and only if you don’t beat me to the bar to buy those beers first lol!

I felt the same exact way when I tested the m5c.. I was shocked at how slow it felt off the line. I couldn’t wrap my head around it and thought there was no way it could do the 0-60 claimed time.

Two days later I drove a a regular m5 that had 2k miles on it and it felt much faster.

The difference between the two? I drove the m5c in 105deg weather and the m5 in 75 dry weather. I think these cars protect them selves and end up pulling power.

That was commonly known on street bikes back in the day. Cars didn't have break in periods but street bikes did. I always kept my rev range going up and down. Never held one rpm range for a long period but rode them semi hard but only for short periods. My bikes always ended up being faster than my buddies stock bikes after break in.

Okay, I'm back! Finally got a draggy and an M5 yesterday.

M340 40-60mph - 1.73s
M5 40-60mph - 1.74s

I can post the runs later and do an actual 40-60 in the M340.

The downshift in the M5 takes longer, and 40-50 the M340 feels like it pulls much harder. The M5 took an entire second to get from 40-50 mph and the M340 did it in about .75 seconds. Also the initial kick down in the M340 is much faster. The test isn't quite fair also because the M340's time was from a 0-60 run and the M5 was from 37-60. However, the M340 kicks down hard at that speed and if anything it may be faster in that test.

All of that being said, I swear the dealership unlocks the ECU when you take it home. I was disappointed again on the test drive, but thought maybe at the 1200 mile service they'd unlock something. After driving it for a day, this thing is a beast! It does have the annoying delay to start pulling. It's a little sluggish. But once it starts pulling... it is ridiculous. It's scary how easy it is to accidentally get close to 100 mph when just trying to step on it for a few seconds. It feels like a rollercoaster. Not disappointed at all!

It also opens with age and miles (or perhaps just the latter). The exhaust gets more raucous and the throttle response becomes snappier. To me, at least, the power at the top end of the RPMs also got bumped (unrelated to tune if you have one).

The 1200 miles service on both my F90s made no difference whatsoever... just time/mileage. This engine loves having you wring its power out if only the transmission could just keep up at the very top; a 500RPM short-shift works best once you're through 2nd.

Thanks, that's good to know!

May be there is some software glitch with this car as explanation for all of this
I test drove 3 M5 before I bought mine 6 weeks ago
every time the car felt super fast and I am used to fast car ... my previous car was E63 S AMG
then I bought my car and it felt fast but not super fast , I was almost disappointed
last week I had my 1200 mile service and the car felt immediately different and super fast similar to the M5 I took for test drives
I am not trying to stir debate and I have owned several M cars including F10 M5 and never noticed/believed that 1200 mile service does anything different to power
so what do you guys think
anyone has similar experience

[gpdriver17]

That's odd, I'll let you know after my 1200 mile service. Again today it felt kinda... eh. Fast, but not like it was the other day. And I was even going downhill while I was on it. Maybe it has something to do with the air temperature or some other variable? It was a cool morning for me when it felt crazy fast, today it was about 85. The salesman said they "open things up" at the 1200 mile service. But he was also trying to make a sale, so who knows.

Once it hit 5k rpm I could tell it was fast, but before that it felt like it wasn't doing much of anything and even after that it didn't feel fast. It was so smooth and quiet I think the speed was deceptive. I know on paper the car is ridiculously fast.

On paper? C&D ran 0-60 in 2.8 seconds. MT in 3.0 seconds.

It's crazy fast. Are you sure you were pushing down on the skinny pedal on the right?

[M3PGH]

the weather in my area was essentially the same and so far after 5 days it still feel super fast ...
it was summer when I had the test drives
so temperature can't explain it

Others have reported 3.4 and 11.4, so testing varies.

Can you tell me where they ran the 3.4 to 60 please? I’d like to see that review. Thanks.

I knew that going into the test drive! That's why I was initially interested. Those are supercar numbers. Definitely was pushing all the way.

2.7s is the fastest I've ever done across both of my F90s (that's tweaked a bit, though).
