The sticker consumption figure on all cars are really a lie!
They are achieved under ideal conditions with a lot of variables thrown in.
ML350 had a 76lt fuel tank with a 96lt option. Dealers always specify the 96 lt tank. Why? The 76 lt tank is lighter for when they do consumption test.
It had different tyre pressure placards on the fuel tank lid, and door pillar. Why? So they could test it with higher pressure - rougher ride but less drag - less fuel used.
They know exactly what figure they can achieve when the car is independently tested. But if it is not tested prior to release, then the factory claim is accepted provided it is within 10%. So they claim 9.9% better which will be accepted.
So these figures are never achievable, and can only be used to compare with other cars making the same lies.
As for the GLE500e, I can achieve 0.0 l/100km (infinitympg) driving to the milkbar on E-Mode. But on a long highway trip, I average about 8.0 l/100km (35mpg) That is far better than the GLE43 which has the same motor but no hybrid.
