Engine Start up...
Both manuals for the cayenne and GT3 say that you should drive the car immediately after start up and do not let it warm up from idle. What's up with this??? Common sense would tell you that it's better to let it warm up a little prior to driving, especially since the idle rpm's are higher. In the past I wait for the rpm's to decrease to the normal idle speed prior to driving it. Is this hurting my babies??? Anyone have any insight on this???

Just what I've read in previous posts.... that it's important to "warm up" all of the drivetrain and suspension parts as well as the motor, and that would indicate moving right after startup. I question that in the winte however, 'cause I'd like the cold oil to thin out a bit before I put any load on the motor.

The warm-up process has been long gone since the quicker heat-up systems due to emission systems in the past decade or so. It you let your car idle, it will pollute the air more. As such, drive it off and keep the revs low until engine is fully warmed.

I suggest that you follow the owners manual instructions and drive the car away.

I've always been told that prolonged idling is bad for the engine. One of the bad things about stop and go traffic, Maybe it has something to do with idle rpm being sub-optimum working conditions, like lower oil pressures and what not.

I grew up in a General Motors Exec family...in Mich. It was driven into my head to warm the car up before putting a load on it and let the auto idle for a few minutes before shutting down after driving for any lenth of time. I now believe those issues were tied to oil composition and engine parts. Being the Porsche runs Mobil1 syn and technology is superior, I believe those issues don't apply any longer.

probably because in Germany and many other countries, its illegal to idle the car (even in the garage)....pollution.
Forgot that while I was out in winter checking the maps on the side of the road....immediately some cops stopped (machine guns and all), and told me to shut off or drive off.
Asked that question in Germany of a cousin that works at BMW German and apparently that's an old wives tale. With modern tolerances, fluids and electronics, driving away right away is what the cars are designed to do (at least the German cars).
