Don't have the AMG GLC43 4matic Coupe and it looks like people aren't logging in their estimates on fuelly. There's only one and the owner average around 19.1 mpg. That's not bad and just a bit under the manufacturer provided rating of 20 mpg.
Rickolas I’ve got a 43 had it since March and overall in 7500 miles mines averaged 24mpg, on a long run you can get 27-28 sat at 70-80 on the motorways.Hi I'm new to the group, I'm test driving a new GLC 43 this Friday and I really want to know what peoples MPG are like, round town vs long journey. I'm coming from an X5 40d msport.
