Good point, getting the best MPG possible is huge these days especially when the difference is as big as this. I rather have a sexy CLA that gets 40 MPG than some boring and ugly Volvo that gets 25 MPG.Huge difference is the fuel economy for those who cares about that. Although no published numbers yet for the CLA, it has been estimated that it will be around 40 mpg combined. That's much better than the 25 mpg for the S60 T5.
