Well, BMW is part true. The main point isn't to get the engine up to operating temperature, the point is to get to the cat lit off as fast as possible. This is accomplished by timing retardation and a low A/F ratio.

Now, holding in engine heat will allow less fuel over a drive cycle which means better economy, lower toxic emissions as well as lower C02.

I'm all for it. Good job BMW.
