BMW also tends to introduce a new engine with each new model or facelift, though for the X5, all the possible choices form a very short list.
One of these possibilities is a hybrid powertrain since BMW has been exhibiting concept ActiveHybrids. An X6 hybrid has even been spied doing tests. It could also just be the 4.4-litre twinturbo V8 in the upcoming X5 M but M cars are treated as separate models in Munich.
The new X5 is expected to make an official entrance before the end of the year.
