I agree!
IMO the proper brake-in has to be done for at least 500km. All the pices on the car are brand new, from transmission to suspension, tires and so on...so for 500km try not toa buse the car. IMO after this you can build up the revs progressivly (meaning in 2-3 days) to the red line. Same goes for the speed.

i agree as well - i think a fairly gentle break in for the first few hundred miles or so is a reasonable and sensible precaution for the reasons you state, some moderate abuse from that point on isn't really going to do any damage.

I would never buy a dealer demo. If you are only going to keep it two or three years, OK. But if you keep them a long time like I do, it is better to break them in by the book, IMO.

I agree, Jim.

Agreed.

CVT Benhogan,
I'm sure you weren't the first person the sales guy told to "open her up."

And while there are many opinions on what the proper break in procedure should be, every BMW, Porsche and Mercedes I've owned called for a break in period--it's not just the engine, but the entire drive train. Porsche, for example, builds their engines by hand, then puts them in a room on a bench and tests each one--and rather aggressively at points--but still has a recommended break in procedure. I follow the break in procedure, then gradually increase the "sportiness" of driving over a few hundred miles.

I redlined the car I was testing many times. I want to DRIVE the car, see what it can do! Now that I saw what it can do, it moved quickly to the top of my list, so there's certainly some benefit in testing with a salesperson who doesn't care about break-in.

Frankly, I think it is bunk - I highly doubt a proper 1200-mile break-in period is really necessary. These are performance built and performance tuned engines - they are made to take this and much much more. If I get a brand-spanking new one, I likely will not obey by the traditional break-in period.

Yep. Correct!
Don't worry about! No problem!
The engine doesn't NEED the break-in.
