Following its tests, CR managed to return 47 MPG on the highway, a substantial increase over the EPA’s 40 MPG rating. Combined, the 2017 Cruze returned 30 MPG in both city and highway driving. The figure also puts it within arm’s reach of the 2017 Cruze diesel‘s 52 MPG highway rating.
The report states, “given the impressive figure, it might not be worth waiting for the diesel engine.” Though, we would say if you’re looking for oodles of torque, the diesel will certainly be worth the wait.
However, the substantial 52 MPG rating is only valid with a manual transmission. Cruze diesels equipped with an automatic transmission will only manage 47 MPG highway. Coincidentally, that’s identical to the gasoline-powered Cruze’s rating per CR. The Cruze diesel does manage to return 37 MPG city over the regular Cruze’s 34 MPG city rating, though.
The EPA estimates yearly fuel costs to be $1,050 for the Cruze diesel and $1,000 for the petrol-powered Cruze. When it comes to deciding which suits a driver best, it’s hard to go wrong when taking fuel economy into account.
