Okay...just read the whole damn Canadian manual (I think its the same for US and Canada) to find a brief paragraph on page 18..."Breaking in the vehicle"

As frankchn noted, the above guidance is for first 2000 miles or 3000 kms... That's all there is...evidence vs emotion.

I’ve never followed break in for any new vehicle and have never had any problems.

Yes - well sorta:
Whatever you believe....If nothing else it’s an informative read
Naysayers can pontificate

Fair enough. And per Andreas Preuninger:

"I can only tell you how I personally do it, or how we do it at Weissach – for the first 500 kilometres or 300 miles, we don’t drive that car car ever over 5000 rpm, never. From then on, every 200 kilometres, we up the rpms by 500, so we end up at 1300, 1400 kilometres at the threshold before we can really go full throttle, at 800 or 900 miles.»
He then went on that this procedure was really important for the GT3 RS engines given their more «delicate» rings - and how important this break in really is for any of their engines."

So who do you believe? And if AP's advice, specific to GT3RS engines with high RPM capabilities and delicate rings, is an 800 mile break in, how less stringent would he be on a beast like the TT/TTS? And how does that reconcile with the 2000 mile break in recommendation?

It all seems apocryphal, IMO.

I was replying to Pad's original post. So, no- I only have "anecdotal" experiences. Deepest apologies.
The shop foreman I mentioned has been working on Porsche's for nearly twenty years.
But let's make sure to discount people's people's personal experiences. 👍🏼

Drove mine to the office, picked up my business partner and did 5 launches back to back and a few high speed pulls and slammed breaks a few times. Broken in 👍... everything works.

No need, really. With modern pads that makes no difference. I went through dozens of sets on my 911s over the last 7 years (5 911s, ~150 track days) one way and another, and noticed no difference. Bedding will get the transfer layer on rotors, but the layer will rub off when driving with cold pads, which is practically all of the street driving. So on street, you have no transfer layer on the rotor either way, and on track you get the layer formed within the first 1-2 laps. Just smooth brake application on no abs on new pads.

On break in - I like to take it easy first 500km+ (double that on a GT car) or so and then anything goes. I still let it warm up before high revs and not bounce off the redline ever anyway, though. Some anecdotal stuff - take it for what it's worth:

Picking up 991.2 Turbo S at the Leipzig factory I asked how many km to put on it before I take it to Nurburgring. The answer was not to worry about anything because they put theirs on the track at porsche performance delivery center straight from the factory. I still drove to the Goodwood festival and back before tracking mine, just in case :-).

When I got a new engine on the 2014 991.1 GT3 (the big exploding engine fiasco they had with those), they just told me not to track it for the first 300 miles or 500km, whichever I prefer, LOL. With a new gearbox, they told me no track or launches for the first 200 miles (they replaced gearbox on my gt3 due to a defective oil pan).

Break-in for brakes and tires is a myth. Or rather it exists but is very short - less than 100km on street or 2 laps on track. During that time all kinds of lubricants on surfaces can cause the car to act a little less than ideal, so it's a good idea for Porsche to cover their rear bumper with some break-in language.

Anyway, I like taking it easy with a new car - a good excuse to take a leisurely road trip and get to know the car. Kind of like swirling and smelling wine before actually drinking it.

Thanks for sharing. Does someone have the European guide for the 992 model as your link dates back to 2013? I hope some of our British forum member can share that so we don't have to google translate .
If it is similar to 2013, then I would agree with the guys that have stated that you drive it hard from the start with following basic rules of engagement (wait for operating temperatures before the hammer).
There's no way I am not doing race starts past my first gas tank lol. I do not have that much self control.

sechsgang

Eh, and no evidence here other than it's just what I've done...I go about 2-3 tanks of fuel at just running it around every gear and generally under 5k and then after those tanks I run it the whole way, or nearly. The only thing I wait to do in the car till its got 900-1000 miles is launch control. Otherwise, whatever. If this was a super high revving car...I would alter that a little bit but tbh nothing too different.

abiazis

I make sure no hard starts for first 500 miles and also vary speeds continually through low and higher speeds............around 1000 miles, the engine really opens up, almost on a mind of its own,,,,,,

Pad Bender

Im on my 3rd tank and almost 1000km doing 30-60 min drives. No new engine smells since the first 150 km.

I can feel the engine smoothing out and eagerly moving in tandem with the PDK.

Launch control will soon be in order

RD16RR

....obviously a born rule breaker !!

According to Porsche, breaking in is necessary only for the first 3,000 KM, as indicated in the owner manual.

Now, for the classical breaking in of an air-cooled flat six, you can rely on the recommendations for breaking in an air-cooled BMW flat twin:

• · 0 - 1,000 km > max rpm 4,000 ;
• · 1,000 - 1,500 km > max rpm 4,500 ;
• · 1,500 - 2,000 km > max rpm 5,000 ;
• · 2,000 - 2,500 km > max rpm 5,500 ;
• · 2,500 - 3,000 km > max rpm 6,000 ;
• · 3,000 - 3,500 km > max rpm 6,500 ;
• · 3,500 - 4,000 km > max rpm 7,000 ;
• · 4,000 - 5,000 km > max rpm 7,500.

And these recommendations can be used for the more "breaking in conscious" owners of a water-cooled flat six!

Here is what the 2021 european owner manual says:

Before driving off: important information on your Porsche

Running in the vehicle
In a new vehicle, the moving parts first have to be run in with each other. The first 3,000 km (1,865 miles) are required for this.
The oil and fuel consumption may be somewhat higher than normal during this time.

Drive as follows during the running-in period:

• Preferably take longer trips. If possible, avoid frequent cold starts with short distances.
• Do not participate in motor racing events, sports driving schools, or similar.
• Avoid high engine speeds above 4,000 rpm.
• Drive at low speeds when the engine is cold.

Running in new brake pads
New brake pads and brake discs have to be "bedded in" and therefore only attain optimal friction when the vehicle has covered several hundred miles.
The somewhat reduced braking action requires greater force when pressing the brake pedal. This is also the case whenever the brake pads or brake discs are replaced.

Hope it is useful.
