To start, the 300d will pack 2.1-liter four-cylinder turbo-diesel making 201-horsepower and 369 lb-ft or torque.

This setup is expected to get around 24mpg city and 33 mpg highway.

Maybe with the 9-speed tranny and RWD we might get published mpg of 33 fwy (or by taking e.g., 700 pounds off the rig with the use of more aluminum) but...

2017 Mercedes-Benz GLE 300d SUV 7-speed automatic transmission with 4MATIC all-wheel drive--

City mpg: 22

Highway mpg: 29

(Actual rating will vary with options, driving conditions, habits and vehicle condition.)

I do however get >29 fwy mpg with the 250 BTC which also is configured as above (29 mpg overall)
