engine temp
Hello all, living north of Phila,PA. Outside temp"s around 13deg with high wind chill. My base MINI with 3-cyl engine takes close to 12 miles to reach max engine temp on gauge, is this the norm out there? heater works fine during this time but then works outstanding once engine reaches optimum temp.
Thanks for your input. Jeff

I'm in Colorado and we've been at the same temps and even below 0. The engine does take a while to warm up. I bought an OBD2 reader that will show temps in degrees and it confirms the slow warmup. The explanation I heard is the engine is so finely machined that there is little friction, hence the long warmups.
Glad to have the seat heaters.

The answer is in this question: Why does it take more hot water to make cold water hot than it takes cold water to make hot water cold? Thermodynamics. Heat travels TO cold and the colder it is the harder heat has to work figuratively speaking. Then you plug in the distance/rate/time equation. Instead of having hot air 5 miles from home it goes to 10 miles or more.

It just takes time to bring a considerable sized lump of what is essentially cold metal, filled with cold oil and surrounded by cold water, up to running temperature (approx. 200F).
Even on mild days I have monitored engine coolant temperature and more recently with my new Challenger R/T Scat Pack (which can display "gauges" showing coolant and oil temperatures on the LCD in the center stack) and it can take some engine run time before the engine is up to temperature. In some cases 10 minutes or so.
Neither one of my Porsches had heated seats. My Challenger has heated seats and a heated steering wheel. Nice. I must be getting soft as I age.
My JCW doesn't have heated seats or a heated steering wheel.
But all 4 cars came with auto climate control. This is a really nice system. In auto mode -- even if the A/C compressor isn't on -- when one starts a cold engine the climate controller dials down the cabin vent fan speed so one doesn't get blasted with cold air. As the engine runs, and gains some heat, the climate controller ups the cabin vent fan speed a bit and one feels some warm air.
As one continues to drive more cabin vent fan speed is dialed in and before one knows the cabin is up to temperature.
