I think that's more a function of cooling system design/integration with HVAC. I have a BMW that puts out warm air within 2 minutes of being started. Engine temp takes forever to come up to normal, but the cabin is toasty. Our old Lexus on the other hand took forever to produce warm air in the vents, and yet engine temp came up fairly quickly. I think BMW does some trick with valves and water circulation to bring heat into the cabin as soon as possible.
