Hi!

New at this forum.
(Sorry for my bad english)

Got my self an Mercedes GLC43 coupe 2018 after beeing an Audi owner over the past 11 years.
I'm super happy with the car, but something thats annoying me a bit is the fuel consumption at higher speeds.
When im driving over 130km/h the fuel consumption is over 13l/100km, when im at 160 the conumption is at 15-16l/100km.

Is this normal?

I have had an rs6 2014 and the consumption was lover on this car.

When reading at mercedes stats, the car should not consume more than 10l/100km at 130-140km/h
