Same song, different verse. For as long as I've been a mechanic the term "engine temperature" refers to the coolant temperature. Because it's gives an overall temp reading of the engine. Read what the coolant temp gauge is called on any car, it doesn't say Coolant Temp it says Eng Temp.

I'm no an idiot to think the engine oil, combustion cylinder temp and exhaust gas (for that matter) is the same temp as the coolant. As I said in my post "The coolant system maintains the engine at a set temperature by the OEM and my point is that Porsche runs their engines cooler than any other manufacture that I know."

Quickurt,

I do not agree with you when you say "The Europeans understand the purpose of the suspension system is to keep the tires in as close to perfect position and loading at all times, to maintain near perfect adhesion between the tires and pavement. Ride comfort is compromised in favor of control.
American manufactures understand the purpose of the suspension system is to give the car as smooth a ride as possible over any type of pavement surface. Control is compromised in favor of ride comfort."

As explained to me by a German in Germany in simple terms as follows;

German cars are built to withstand the Autobahn. The speed, the curves and stopping. Hence the power from Porsche, Audi, BMW and Mercedes. All these cars are built for high speeds, maintaining high speeds and being safe at those speeds.

American car manufactures don't have to build their production cars to those standards. Max speed in this country is 75mph and that's their benchmark and cars are built to that. As a quick example just look at the oil capacity on American cars, 5 quarts. Why do you think our Boxsters have 9 quarts? It's not because the engine has that much more to lube, it's because when running at sustained high speeds for a long time the oil needs to have the ability cool before being sent back around the engine to cool and lube. You think race cars have 5 quarts in their sumps?

So to sum it up, European cars are built stronger because of the Autobahn, American cars are not. I won't get into the fact that there are cry baby Americans that complain about a stiff ride (and won't buy) without understanding the reason for that ride.
