  1.  @Saif0412  Dont agree. Its got a bit less. Maybe more than 450, but for sure less than 500.

  2.  @Roddy_Zeh  Sure it has, but its still a bit too slow for 500hp.

  3.  @dylanhall509  No it doesnt have that much effect. This hasnt got 500hp as tested.

  4. Its almost like there is a formula to calculate power from acceleration... hmmm.... Nah, you are right, has to be wizardry.

  5.  @Hackerproo  Weight makes a difference, but is not that different all in all.

  6.  @lambertomainardi7933  Dont have the time or energy to calculate to formula while I am at work, but since I have owned one myself, I am a bit familiar with them and it should be 450-470 or so depending on the consistency of the powerband. Of course, outside temps and wind and other smaller factors makes a difference as well. But 505 when this video was made? No, thats not possible in normal conditions.

  7.  @JerainJezza  So a bit more power than an earlier car, then.

  8.  @lambertomainardi7933  Aero we can find from BMW spec sheet. Temperature we can see in the cars gauge cluster, its very normal (20.5 C). The other factors have a small influence in a 100-200 acceleration. Presumably the car works as it should, otherwise they should not quote power or even test it at all.

  9.  @thomasholdsworth2422  Drivetrain loss isnt that big these days in most cars. 500hp seems very unlikely during this test.

  10.  @chiel-  I am sure it is, but dynotesting can differ quite a lot because of for example: How Different brands of dyno calculate power. Different calibration of the dyno. How the measuring is done (Time for sweep or static for example) And how the dyno operator chooses settings. As an example, it is very possible to make a true 500hp turbocharged car show anywhere between 300-600hp depending on the above.

  11.  @chiel-  Yes I do think its a bit slow for over 500hp. Nothing too dramatic but a little bit. He is spinning in 4th gear with AWD? Sounds incredible, how did he manage that, has he disconnected or modified the drivetrain software?

  12. They dont I guess. But not as big of an issue in EU as US.

  13.  @The_Noticer.  Mostly oil quality and regularity of high load driving, I think. Fuel quality might be a factor, but hard for me to see how that can affect intake manifold build up. So, I think its mostly the first 2.

  14.  @The_Noticer.  That is true, its been so long since I ran a car with EGR active that I forgot about that factor a little bit. Still, question is how big that factor is compared to the oil vapor. 25k km is actually very doable, and more than that if you got good oil and very good driving cycle. Many cars from this time period ran 30-40k kilometers between oil changes. For sure my M135 showed a very long interval on its service meter when I had it. It works surprisingly well if you drive the car briskly on autobahn every day. If you on the other hand live in a cold climate and do short runs at low speed city driving, 10k km oil change interval is too much. Were are you located? I doubt resale value is too much affected by carbon buildup woes, probably most people dont even know about it, rather other market factors seems more likely to me.

  15. Yep, sure seems like it.

  16.  @lambertomainardi7933  No, its called simple math. Acceleration is directly proportional to power/weight. From the video we can see the acceleration, and the weight can be found in a spec sheet. Now we can easily calculate the missing factor; power. Many learn it in school, nothing supernatural about it, I assure you.

  17.  @lambertomainardi7933  Not precisely of course, but within 10-15hp margin of error is possible to calculate from the video. Saying it had 505hp is therefore easily falsifiable. Check out other autotopnl videos, a lot of them have similar comments. Wishful power numbers are as old as cars itself. Because it sells tuning kits.

  18. Do you have a PWG or EWG car? That makes a difference...
    1
  19.  @JerainJezza  Yes, I know. Had a PWG car myself a few years ago, but that didnt matter much because I was planning to change everything anyway. Long story short, I sold it. A shame, really ticks a lot of boxes, but it just wasnt for me, couldnt make friends with the steering. Cant get a legal tow hitch either, as far as I know. I bought an older car again instead, which I still have.
