highway travel and range
Hello,
I'm taking my new to me 2013 SL550 on a weekend trip. One way distance is 340 miles. What range can I expect on a long highway trip? I've only had this car for a week so I have no idea what to expect for MPG. I'll expect to be going around 70-75 on the highways.
Thanks,
Barry

Use your cruise control and keep the pace steady for the best mileage. I’m guessing somewhere in the 25-27 mpg range. If you’re on flat land, maybe 30 mpg. It’s really about letting the Distronic+ Cruise Control do its thing.

I drive my MY14 SL 550 on quite a few long range trips. I usually see around 22-24 MPG on average, but don't really check it. I bought the car to drive knowing that it wasn't purchased for an economic vehicle.
Trip from Atlanta to Pensacola, FL around 375 miles each way uses about 3/4 of a tank each way. Drove to Wichita, KS, around 1700 miles each way and got around 22 MPG if I remember right.
Just drive it and enjoy! It's worth it !

I recently did an 80 mile run (in Florida, so pretty flat), transmission on 'E', ACC set to 70, roof up (Missus B doesn't like the heat and humidity in her hair), climate control at 78F and it returned 29.2. (Mine's the 4.7 biturbo ...)
