It was 19 F out this morning here and we had to make a trip so I warmed the TDI up a little and drove slow for a few miles and she started warming up slowly. By the time I hit the hwy and 55 mph it was at the normal 200 F degrees. We got where we were going and left the car outside for about one hour and came out and turned on the heated seats. Oh I love those. I started the engine and looked at the temp and it was 190 F. Some how the motor retains the heat. I had noticed this in warmer weather but thought once the cold and wind hit it would not hold the temp. It was up to 200 before we left the parking lot. Also the Michelin Latitude ice X 2 tires feel really sure footed on the road.:-D
