saw that. actually suffers quite a bit compared to the C class. Interesting seeing as how this as 9 speeds and isn't that much heavier.

I think that the new testing standards are tighter in 2017. The GLC, which weighs in at a bit over 4,000 lbs has the same rating as the E300 with same engine and transmission. I find it difficult to believe that the mpg is the same for both in real world scenarios. My E550 averages 23.8 in combined city/highway (currently 54000 miles on it now), but the EPA rating is 20 (16 city, 24 highway).

My 328d easily gets 53mpg (US,not Imperial) on Interstates that are at least somewhat hilly.If I were to drive the southern portion of Interstate 95 (the portion in South Carolina,Georgia and Florida,which is entirely at sea level) I'll wager that I could get 55+
