Not all of them do. My diesel VW struggles to maintain coolant temperature in really cold weather, and even in summer the radiator fans almost never turn on unless the AC is used. When it's -25C out it takes 10-15 minutes before I get full heat out of the vents (hooray for heated seats), and if I pull up to a stop light with the heater on the coolant temperature immediately starts to drop. And there's nothing wrong with my car; they're all like that. And the fuel efficiency reflects it: I normally get about 5 L/100 km (46 mpG).
- cmrdporcupine 4y agoyeah I recall my old VW Jetta TDI taking longer than I thought it should to heat up in the winter. Which I always found strange considering the amount of BTUs in diesel and how well my (at the time) diesel oil furnace was at heating up my house right away and also how small the cabin was. In any case, my Chevy Volt heats up the cabin pretty fast. Though once it gets below -10C the stupid thing kicks on the ICE even though it doesn't need to. Something to do with regulations around ICE drivetrain components and temperatures. It just uses it to heat up coolant lines for the ICE itself, even when I have no desire to use the ICE.
