Yeah but what does he set the cruise control at? That makes a huge difference. My '12 Focus should exceed 45mpg pure highway if I set the cruise control at 55mph.
One couple got 84mpg on a long highway trip in a Passat TDI. But they also got 65mpg in a Cruze Eco. Both gas and diesel can far exceed expectations if driven right. In that scenario the Cruze Eco would probably've been the overall more economical choice, given the price premium for diesel engines and fuel.
