So, I've had my 911 S for about 6 months now and I drive kind of like a grandma. I'm a pretty laid back dude. 12k miles now.

I let my friend drive it, and he slammed it through the mountains. On the way back down the engine light came on and it said "Coolant Leak".

My question is whether driving aggressively with higher RPMs is actually better for the engine?

I've heard that this is the case for high performance vehicles like Ferrari etc, is this also the case for The 991 S ?

If you let your friend drive it, then who exactly is this "we" that "slammed it through the mountains"?

Anyway, the answer is yes. And you can feel free to bring it by my place any time your friend is unavailable. Once a month should do it. Please remember to take your Dramamine at least 2 hours before launch, I mean drive time.

For me it was straight out of the dealer and then 235kph on the autobahn on the way home….and I swear that after my first track day at Leipzig the other weekend where it was redline a godzillion times around the track, the car now actually feels stronger.

The notion that a sports car has to be revved dates back to carburetors with rich fuel mixtures and rings with lots of blowby. Hence the need to 'blow out the engine'. Cars haven't needed any such treatment in decades.

So babying is obviously better for the engine, lower revs means less friction, less heat, less wear.

That being said, you bought a sports car, if your not going to drive it like one, why own it?

There has been a lot of technical evolution. But even in a plain old Carrera, all the engine mappings, exhaust valves, manual shift levers, sport and squiggly line buttons and especially that dial right in front of the driver have to be exercised to keep cobwebs from forming. Oh wait, are you guys concerned about the car?

If I take her out I redline that sucker. The day I don't do that anymore is the day I buy an S-Class.

Here is proof of the point made above. Watch the cobwebs.

you broke it.

My local mechanic has stated that he sees more problems with cars that have been "babied" that from those being driven aggressively. Don't know the truth, but it is what he stated when I asked the same question.. I was more concerned of the aggressive driving, not the babying..

The old lore about cars needing to be "blown out" is like todd said very old indeed. With DFI and all the rest they can be driven quite sedately with virtually none of the harmful carbon build-up seen in carburetor/distributor days. And yet a lot of guys like Chris 3963 have noticed their car really does run better after being rung out at the track. It still makes a difference, just nowhere near as much as 30 years ago.

The one time it really does matter is the first few hundred miles. That's the window for seating the rings, a process that happens best under full load and RPM. But nobody wants to hear about that.

I have given each new Porsche I've owned about 1K to settle in before redline, after that I don't rag on it each time, but I do drive it as intended, it is a sports car.

The last thing one should ever do is drive them hard. They simply will not take it. Fragile as can be.

I drive it like I stole it, from day 1. Never had any issues and have never had to top up the oil. The cars were not designed to be babied, but properly driven.
