Maybe this is a dumb question, but I searched and cannot find the answer. It is my understanding that the 750 Hybrid has 455 HP (20 extra comes from battery boost?) and the X5 towing package with 4.4 engine (or is it a 4.8?......why didn't they do that for the 750??) has 440 HP. If these numbers are accurate, BMW is already "getting more" out of the 4.4 engine, but, I cannot get my service advisor to determine if this engine upgrade (I assume they increased the turbo boost) is available for the "straight" 750 4.4.
Has anyone figured out if BMW can do this upgrade on a 750 4.4? To earlier posts, I want to layer this on before doing the Dinan stage 1, if possible.
thanks in advance....kt
