Default "Warming Up" Your P-Car Does Nothing. Here's Proof.

(If you've got a non-carburetor Porsche, this article and explanation from an engineer settles the debate.)

That article is talking about the idea of sitting in your car, idling and allowing it to get up to full operating temperature. I don't think anybody does that anymore. It has absolutely nothing to do with the concept of allowing the car's oil temperature to reach the appropriate level before driving the car hard, which is what people on a forum like this are referring to when they say 'warming up the car'.

I did wonder which "warm up" we were talking about based on the title. Very few people do the sit+idle waiting game when they start the car.

My neighbor has a Cayenne GTS, and I think he wins the "fastest getaway" award. I can't even count a second before ignition and drive-off.

Sounds like me, engine start, clutch released, and it's off I go. RPMs below 4k, for the first 5 miles.

I prefer to just drive the car mildly and that way you warm up the engine, transmission, and differential all together.

I wait until the idle settles from fast to slow, which usually takes about 25-30 seconds, then I start driving but I try to keep rpm under 3k until engine oil is > 150 degrees F.

Even Porsche manual says do not warm car up. Start the car and go.

Germany has very strict and highly enforced no idling laws. No need to warm up a Porsche, drive it easy for few moments and then have at it.

In a diesel, especially, idling to warm up a car in cold weather simply won't work. You have to drive it - put a load on it - to warm it up. Even then, my pickup, with a Cummins diesel, takes a long time to warm up in anything below 20 degrees. Our Cayenne diesel warms up quickly, though, even in pretty cold weather.

I also start the car and wait for the revs to drop below 1000. That usually takes about thirty seconds.

On cold winter mornings, some folks will fire up their cars and leave them running for 10, 20, maybe even 30 minutes, thinking they're reducing wear and tear by letting their cars warm up gently.
Um, no, if I'm doing that, it's because I don't want to drive off in a freezing-cold car whose heater isn't working yet.

The car serves my purposes, not the other way around.
