I've just done a quick Ebay search on viscous couple engine driven

Over to you to prove no current car has one.


No, fair enough. It€˜s just a long time since I€˜ve seen one. Most of my cars
over the last 25 years or so have been transverse engine, FWD. It is
possible the my Jag XF had a viscous coupled fan, but I never looked. ;-)

I'd certainly agree electric is likely the most common these days. Not so
sure about larger traditional layout RWD from the likes of Jag, BMW, Merc
etc. I'd guess the costs of a powerful electric fan and the alternator
needed to drive it have come down, relatively.

The alternators are far bigger than anything needed for an electric fan
- on my previous car, it could drive a 1kW electric heater to speed up
heating of the car, as the highly efficient diesel was too slow to warm
up in the winter!
