During our test, we achieved around 40 kilometres, which isn't bad but doesn’t meet the expectations. Fortunately, the drive train is very refined: the discrete six-cylinder and the electric motor interact hand in glove. When the petrol engine is pushed a bit harder in the sport mode, it sounds very nice, which is something we couldn't say about the four-cylinder in the 740e..
BMW claims a fuel consumption of 2.1 l/100 km. Unless you can recharge every 50 kilometres and barely wake up the six-cylinder, you won't equal this number. Tax wise the 745e is very interesting as far as its CO2 emission doesn't exceed 50 grams. So keep that in mind when configuring the car. The fuel tank is rather small at 46 litres and forces you to make regular refuelling stops..
