I drove my 2018 MB E300 (4 cyl) from Florida to eastern Long Island (1200 Mi.) and averaged 33 mpg according to my car's trip computer averaging 70 mph.
So I am impressed with the E450

Wow that’s actually pretty impressive given it’s performance envelope! Kind of one car that can do everything well! Just curious how it’s long term reliability is with all those gadgets

But moist air always improves mileage that’s why in WW 2 aircraft they used water injection, well not really the same thing although water does not compress so acts to increase power but in a car engine with carbs it works for fuel efficiency
But since you are using FI there I have convinced myself I am wrong lol

How is comfort I wanna buy this and tune it up wanna buy it cash and do some tuning and add extra 80 to 100 hp to it how is handling ? I wanted to get cal 45 but I like comfort and this has air suspension so I assume is very comfortable I like comfortable sport cars and this is also a great price for what it offers honestly best every other car out there

Intend to trade the E350 in and lease this, purchase at lease end. Mercedes takes every lease dollar spent off original sticker price which is great!

Which gps speedometer app do you use? I’m curious, I want to check the speedometer on my 21 RAV4 Hybrid%
