Key Differences
-
The 7 Series has 75 hp more power
It’s a lopsided result (375 hp for the 7 Series, 300 hp for the G80) and one of the main reasons to choose between them. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
-
The 7 Series has better fuel economy
The spread here is large: 28 mpg on the 7 Series versus 24 mpg on the G80. Expect to notice it. The 7 Series uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The 7 Series has 72 lb-ft more torque
Of all the specs we compared, this is one where the 7 Series makes its strongest case: 383 lb-ft against 311 lb-ft. The 7 Series’s extra torque makes it more relaxed when fully loaded or towing.
-
The 7 Series has better city fuel economy
The 7 Series clearly leads on fuel economy (city), and 25 mpg versus 20 mpg is a difference that reaches well beyond the spec sheet. In town, driving style has a big effect, but the 7 Series starts from a better baseline.
-
The 7 Series has better highway fuel economy
On fuel economy (highway), the 7 Series edges out the G80, 31 mpg to 29 mpg. Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.

Space & Practicality
Too close to call
There’s little to choose between them when it comes to space & practicality. So space & practicality is a non-factor here; move on to the areas where they actually differ.
Off-road & Towing
Too close to call
Neither pulls ahead on off-road & towing; the numbers are close throughout. Don’t let off-road & towing decide this one; look at the other sections instead.
