At the end of the day who cares. As many have said these cares are made to be driven HARD!! These aren't garage queens. These aren't collectors items. Somebody has some serious placebo effect going on. The car is fine. Drive it hard like it's meant to be and keep it happy.

You are absolutely correct in that these cars can handle the abuse. I just find it bothersome to know my car is not being treated with professional care and respect. It bugs me.

But, you are correct in that there is no real harm.

[visualguy]

I disagree on the no harm.

In some cases they cause damage to the car by hitting something while driving it recklessly. In other cases they cause damage to the tires. By the way, these cars aren't "built to be driven hard" on cold engines.

In my case where they abused my Porsche Cayman GTS, I started having problems with the 2nd gear on my manual transmission where it wouldn't engage the gear smoothly, and it made metallic noises. I didn't have this problem before. The transmission was replaced by Porsche, and I had it done at a different dealership.

By the way, I managed to take a video of some of the abuse, and showed it to the service manager. He agreed that it wasn't right, shouldn't have happened, etc. He said he talked to his people about it. However, it didn't seem like he cared much. I sent the video to the general manager as well, but never heard back.

Is the OP even still around ????

Although I'm not condoning the alleged abuse of another's property nor am I advocating breaking the law, providing the car had been fully warmed up (oil, tyres, etc) straight line 'sprints' shouldn't have damaged the car. The general unwritten real rule of thumb for m cars is gently bring car up to operating temperature, then full throttle acceleration in short bursts, avoid sustained hard driving (I'm not talking about maintaining steady high speed on autobahn, etc).

You can tell when a DCT equipped F10 M5 has been driven hard as you can start to feel the gear changes, throttle response becomes more aggressive (could be an explanation of car sounding different), etc. Prelonged smooth driving results in inperceptable gear changes, smooth throttle response, increased fuel economy, etc. To reset the car either start driving smoothly for a period of time, or alternatively don't drive the car for about two weeks (noting that the later may not be a practical option). The F10 M5 adapts to driving style same as other BMWs.

Pilot Super Sports are quite sticky, so the surface can look somewhat somewhat worse for wear after enthuastic and not abusive driving. Having chunks of tyre missing would be indicative of extreme track use / burnouts / drifting, etc. Would need to see pictures of the tyres to comment further.

Finally, properly testing a performance car post-service is not as uncommon as you/your friend may think. There is a difference between properly testing and abusing though...

I fully agree with all the above. Very well said. Obviously spoken with experience.

I actually mentioned this theory to multiple service managers and technicians at two BMW dealerships because I have excessive oil consumption on my 2016 550i (1qt per 1400 miles). They all basically said that the "not driving hard enough" theory is baseless - there is no such information from BMW, and there is no evidence that it's true. By the way, I do drive my 550i hard pretty often (sport mode, fast acceleration, etc.)

They all told me that the high oil consumption on these engines is very common and considered normal. They don't know of a way to avoid it, and they don't recommend doing anything about it unless there are other symptoms. They offer a free top-off service for people with these engines, and that's about it. One of them even said that I should just dump this car if this bothers me too much, and his general recommendation is to stay away from BMW V8 engines.

Exactly visualguy.

Probably some lama ever got creative in his own delusional world and said ''the car is not being driven hard enough and therefore not sealed(????!)'' and all the sheep follow.

I would even say the opposite. By not following break in procedure (driving it hard off the lot) you would create an excessively oil consuming car.

It seemed to have worked on mine. I've driven mine hard since the day I did European delivery. Put a tune on it with 3,000 miles. Just hit 28,000 miles and I've NEVER not once had to add a single drop of oil in between changes. It may be baseless in formal testing but countless real world examples can't be denied. The N63 is a POS but it seems like the harder it's driven the better it runs.

[EL Jeffe 5]

Good God some of the comments are just out of this world
Your friend thinking of bringing lawyer WTF
Tell your friend its M5 not Ford Fiesta car is meant to be driven hard.
Every time I drive my car its in sport mode and pedal to the metal.

[SLVSRFR]

My car is always driven hard, correctly and by me.

There's a difference between driving 'hard' correctly and driving 'hard' like an incompetent jacka$$.

If you are okay with your car being driven hard by someone you have no idea their experience of driving then so be it.

But when I had my E60 M5, this performance exhaust shop was installing my meistershaft exhaust and I decided to wait at the shop while the work was being done. The car was being worked on for about 5 hours so the car had cooled down. I hear the worker start my car, rev it like 30 times on the cold start. I assumed he was taking my car back around so that I could leave, nope. I proceed to see my car FLY BY on the open street and could hear it as it traveled down the street. He came back maybe 5-10 minutes later when I was letting the manager have it. I took a picture of the odometer when they took it back, turns out he took my car on a 11 mile joy ride. All work was free and the shop paid for a full inspection of the vehicle from a shop of my choice

[mobilejo]

I agree that these cars can handle a hard drive, but for me what would really P*** me off is that some dipsh*t is joyriding it for his own pleasure - my 50k or whatever car that I paid for, that I am paying his employer to work on - and he thinks its own personal entertainment for 20 minutes. That ain't right however you look at it.

If it was being driven hard specifically for the purpose of what I'm paying them to do (e.g. find the source of a high speed shimmy or something) then fine, but if it wasn't necessary, don't do it just because its FUN. How can the owner be expected to just be okay with that?

[krautmeister]

The OP is a bit younger (freshman in college?) and I'd bet it's a case of car coveting. The basic fact that they are posturing over something like this with lawyers over just joyriding is a stretch. They should take it to another dealer and just have it looked over to comment on whether there's permanent damage. If the tires were beat on, then explain the situation. Its definitely gone on too long though. Dealer would be very vary of a younger owner who is accusing them of abuse several weeks after the fact.

Okay so i'm a freshman in college what does this have anything to do with what the post is about. My buddy is an older gentleman. Don't reference me into this when I clearly posted that this is about my friend and i'm posting for him.

[krautmeister]

Sorry buddy, i was trying to show the lens you are looking through. Now I see it, its condescending.

I would stick with a dealer that made good like that. No reason to think they will mug you in the future to claw back the money; making you a happy customer is worth so much more and they understand that. if they didn't, they would have just said get lost.

I realize this is an older thread... and...
what you write is somewhat correct (believe it or not). But it is in the first 100 or so miles for the car and this should be done and never on a cold engine.
