Our 2014 Mercedes-Benz CLA has been in the fleet a very short time, but its fuel economy is disappointingly low so far.

    let's hope engine break-in improves mileage. or it could be the wonky CEL and some engine management software reducing the mileage. We'll see.

    I think the EPA's ratings are overly optimistic here. 38mpg just seems ridiculous to me. I think most people will be in the 30-33mpg range on the highway. I just have a hard time believing that a bigger (although slightly lighter) and more powerful car is going to get that much better gas mileage than a C250. Having said that, Mercedes are notoriously slow to break-in with regards to fuel economy. Both my old S550 and my wife's E350 reached 30,000 miles before they started to really achieve consistent fuel economy.

    It would seem that your theory about small-displacement turbocharged engines has already been proven true. The Regal is the only one that met its EPA ratings, IIRC.

    I've been driving my CLA250 ~50 miles to work and back every weekday, about 20% local, 80% highway, 10% traffic jams. My "from start" MPG calculator usually gives me around 33-35 MPG. Not too shabby.
