That's what I'm told, that as the car gets broken in, it gets faster, engine loosens up, etc. Anyone experience this or is it bs? Thanks.

I'm not sure about more power but my CS has gotten noticeably smoother after 10,000 miles. The most obvious thing I noticed is my gas mileage has increased from about 18mpg to a consistent 20mpg.

I can't say anything about the power, but the transmission definitely loosened up after a while.

Some engines will actually gain a couple horsepower as the engine is broken in; due mostly to the seals seating on the engine and the ECU adjusting itself. While I dont have proof from dyno runs, look at the long term tests on cars in magazines, they will sometimes run a tenth or two quicker after a year and about 35K miles than they did brand new. I had an RX-8 that picked up 4 mpg average once I was past about 5K miles. I hope the Cayman S is one of those cars!

No question about it, after 8,000 miles my 2.7 is definitely quicker, sweeter and nicer to drive. Not sure if there is more bhp, but the engine seems to respond better now from lower revs, making a bit more torque low down, which genrally makes it more driveable.

Past experience from other cars suggests that most engines are at their best in the window between about 12 and 24k miles.

Here is a good example of what your describing from R&T

"... the Carrera S posted some awesome acceleration numbers: zero to 60 mph in 3.9 sec. and 12.3 to the quarter (we got a 4.4 and 12.8, respectively, in a previous test). ... The only explanation for the difference in acceleration times is that this particular engine had a proper break-in period ..."

Hmm, I wonder what it would have done with an "inproper" break-in

My CS has made a couple of transitions; one at 4K and another at 13K or so. Seems, faster, smoother, more-powerful.

Second that, absolutely. Car is faster, revvs more, etc etc. This after say, 6000 miles on the odo. Saludos

My saturn sports coupe is definitely quicker now at 190,000 miles than it was when it was new. Feels like the 135 hp engine is pulling a full 138 hp now. Hope the cayman gets stronger with time as well.

When I passed 190,000 miles on my Avalon, it flew down the road and hit higher speeds than when I bought it with 54,000 miles on it. In part, I think that car performance varies and adapts with driving style. When we get on them regularly, they tend to get better at those speeds.

My road trip from Arizona to Alabama the last couple of weeks put >3,600 miles on the car and I have passed the 212,000 mile mark. I intend on keeping this Toyota even after getting my Cayman because it is always good to have a spare and it really is a great people mover able to hold five adults comfortably. Besides, car rentals are expensive and I'd like to have it handy for visitors. And I tend to put a lot of quality care into my cars, so there's no sense in giving it up--least I buy and inherit somebody else's problem car.

Besides, this is my "dating" car. They don't need to see my house nor an expensive car least they target me more readily for my assets. I swear in this day and age of judges' bias in favor of the women, all they have done is rip assets from men in a fashion that mimics prostitution and makes stability in marriages more difficult. Damn if I have another one take me!

Mine just turned 2000 and it certainly seems to rev more freely and shifts are much smoother. I prety much went by the 4000 rpm limit during the first 2k so I cant speak to faster or not. gas mileage also seems to be improving.

I got 5K on mine and it definitely feels smoother. It idles smoother, it sounds smoother.
