I drive a 1995 Eagle Vision ESi 3.3L(part of the LH series --> Intrepid, Concorde, New Yorker). Let's assume I turn on the car, let it warm up for 2 minutes and then drive 10 kilometers. The car will indicate that the engine heat is halfway on the gauge (there's no digits on the gauge :S, how retarded is that). Taking my dad's 2000 Impala 3.8L through the same route, the gauge reads one third. I tried the 1993 Cavalier 2.2L under the same conditions, and the gauge reads one third. Why is it that my car warms up much faster than the other two. This is the last thing I want happening in the summer, where temperatures are 35+ degrees ceclius. BTW, I know that the cavalier has a shit v4 engine, but even the impala with the larger engine warms up slower. What could be faulty? Is the thermostat opening too late?

I don't think you have a problem.
Factory gauges are notoriously inaccurate. A lack of calibration on the gauge only makes it worse. One third of the way on one gauge bares no relevance to the same position on another gauge.

Furthermore, the Chrysler engine is acutally a more advanced design than the Impala engine. Engeneers design these engines to warm up as fast as possible mainly to reduce emissions. The newer engine designs do this better.

Your partly-aluminum engine will warm up faster then the all-cast iron GM engines anyways.

If you are worried about the cooling system just do some maitenance. Change the thermostat and give it a flush and fill. If the radiator looks like its getting clogged inside, or is old and deteriorated, then replace it. Also replacing the rad and heater hoses is a good idea, especially if they are old.

As long as it's not over heating it shouldn't be a problem I don't think.

I wish mine heated up that fast; lower emissions, less fuel used, and the heater works faster

Nothing wrong with it as long as it doesn't over heat.

just wanted to say, thx for your help, it's greatly appreciated. Well I'll keep an eye on it this summer.
