Don't they?

When I set off driving with the heating set to auto it's about a mile
before there is enough warmth for the car to bother with the blowers.

I've often wondered about that. Surely the answer would be a much smaller
cooling system? Less volume would heat up quicker? But capacities seem
similar to petrol cars. Or could be a diesel efficiency gets much poorer
at full throttle?
