Turbo's / Warm up / Cool down?
I remember back in the day (think 90's turbo cars), people used to talk about letting turbos warm up/cool down proper to increase lifespan and reliability.
Is there anything with that on todays stuff, specifically for the F8x?

M4 is engineered too precise to worry about that. The vehicle can even increase or decrease turbo pressure based off altitude and weather. You have nothing to worry about but keeping the tires glued to the asphalt

Most 90s cars used oil cooled turbos. A turbo timer let oil circulate through the body of the turbo at idle and prevented coking in the bearings and body of the turbo. BMW uses water cooled turbos and and electric water pumps. That allows the car to pump cool water through the turbos after you turn off the car. ppl way smarter than me are about to chime in but suffice it to say our cars are better able to deal with the heat but I still idle it after a hard run for a couple of minutes just to get my heart rate back down

I read that with our cars you should not warm up in the cold like an N/A engine. Just get in turn on and adjust settings and seat belt and go. I certainly hope this is true, because this is how I do it. Also, coming off a spirited run you should slow it down for the last mile or so home. Efficient, comfort comfort.

also, remember, the turbos in SPORT or SPORT+ mode are "pre-spun". I imagine that this also increases wear of material? nevertheless, that's the reason I put the engine to "efficient" after a spirited drive. warming up not necessary, thoug - that's something I've never heard. I surely make sure that the engine is properly warmed up (i.e. oil temperature gauge starting to "move" and all yellow LED rev limiter lights are turned off except for the last one before the red). that's when she is ready for the ride
