Key Differences
-
The 5 Series has better fuel economy
The 5 Series is slightly stronger on fuel economy (combined). The gap, 31 mpg versus 28 mpg, won’t change your life, but it isn’t nothing. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The 5 Series has better city fuel economy
If everything else were equal, this small edge would favor the 5 Series: 28 mpg against 25 mpg. Hybrids often shine in the city, and the 5 Series has the better rating here.
-
The 5 Series has better highway fuel economy
Not a big gap, but a consistent one. The 5 Series’s 35 mpg beats the E-Class’s 33 mpg. Highway fuel economy matters if you cover long distances at steady speeds.

Fuel Economy & Range
5 Series leads
When it comes to fuel economy & range, the 5 Series is comfortably ahead. Choose the 5 Series and you get better fuel economy. Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold. The takeaway: on fuel economy & range, the 5 Series is the stronger car.

Too close to call
