Key Differences
-
The 5 Series has better fuel economy
The spread here is large: 31 mpg on the 5 Series versus 21 mpg on the G90. Expect to notice it. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The G90 has 120 hp more power
Of all the specs we compared, this is one where the G90 makes its strongest case: 375 hp against 255 hp. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
-
The G90 has 96 lb-ft more torque
The G90 clearly leads on torque, and 391 lb-ft versus 295 lb-ft is a difference that reaches well beyond the spec sheet. The G90’s extra torque makes it more relaxed when fully loaded or towing.
-
The 5 Series has better city fuel economy
On fuel economy (city), the 5 Series posts 28 mpg against 18 mpg for the G90, a gap big enough to feel in everyday use. In town, driving style has a big effect, but the 5 Series starts from a better baseline.
-
The 5 Series has better highway fuel economy
This is one of the widest gaps in the whole comparison: 35 mpg for the 5 Series versus 26 mpg for the G90. Highway fuel economy matters if you cover long distances at steady speeds.

Engine & Performance
G90 leads
The 5 Series is outclassed on engine & performance; the G90 leads by a clear margin. The G90 adds 120 hp more power. The G90’s extra output gives it more in reserve when you need to get up to speed. On engine & performance alone, the G90 gets the nod.
Total system output
5 Series: 255 hp G90: 375 hp Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
Torque
5 Series: 295 lb-ft G90: 391 lb-ft Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type.
Fuel Economy & Range
5 Series leads
On fuel economy & range, the gap between these two is wide, and it favors the 5 Series. The 5 Series delivers better fuel economy. The 5 Series uses less fuel on the standard combined cycle, which matters most if you drive a lot. For fuel economy & range, the 5 Series is the one to beat.
Fuel economy (combined)
5 Series: 31 mpg G90: 21 mpg Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
Fuel economy (city)
5 Series: 28 mpg G90: 18 mpg City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
Space & Practicality
Too close to call
Neither pulls ahead on space & practicality; the numbers are close throughout. Either car will serve you equally well on space & practicality.
Off-road & Towing
Too close to call
On paper, the off-road & towing comparison ends all square. So off-road & towing is a non-factor here; move on to the areas where they actually differ.
