BMW's hybrid limousine
The car is officially a concept car, but it's expected to go on sale next autumn.
It is powered by a combination of a 4.4-litre V8 petrol engine and a lithium-ion battery unit that, in total, produces 427bhp.
BMW says it returns 15% better fuel consumption than the new 750i, upon which it is largely based, suggesting a combined average of around 28mpg.
Also on show in Paris will be a X6 ActiveHybrid.
