Key Differences
-
The GLB has better fuel economy
This is a headline difference. With 28 mpg to the Discovery Sport’s 20 mpg, the GLB has a lead that’s easy to see on paper and in practice. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The Discovery Sport has 25 hp more power
The gap on total system output is slim (246 hp against 221 hp), yet it tips toward the Discovery Sport. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
-
The GLB has better highway fuel economy
Put simply, the GLB is far ahead here: 33 mpg compared with 23 mpg. Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.
-
The GLB has better city fuel economy
The GLB’s 25 mpg leaves the Discovery Sport’s 19 mpg well behind, so if this spec matters to you, the choice is easy. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
