A7 vs G90
Choosing between Audi and Genesis often comes down to a specific pair of products. In the midsize luxury car class, that pair is the A7 and the G90. What you gain on one side you give up on the other: the A7 wins on fuel economy & range, the G90 on engine & performance.

Key Differences
-
The A7 has better fuel economy
Here the A7 pulls well ahead of the G90, with 25 mpg compared to 21 mpg. Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
-
The G90 has 40 hp more power
Think of it as a tiebreaker rather than a deal-breaker: 375 hp for the G90, 335 hp for the A7. The G90’s extra output gives it more in reserve when you need to get up to speed.
-
The A7 has better city fuel economy
The A7 doesn’t just edge this one; 22 mpg against 18 mpg is a lead you’ll feel. In town, driving style has a big effect, but the A7 starts from a better baseline.
-
The A7 has better highway fuel economy
Big gap, real consequences. The A7’s 30 mpg versus the G90’s 26 mpg changes how the two compare in daily use. Highway fuel economy matters if you cover long distances at steady speeds.
-
The G90 has 22 lb-ft more torque
On paper, the G90 is a touch ahead here, listing 391 lb-ft against 369 lb-ft. The G90’s extra torque makes it more relaxed when fully loaded or towing.

Engine & Performance
G90 leads
If engine & performance is high on your list, the G90 makes the stronger case by a wide margin. The G90 stands out with 40 hp more power. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board. That makes the G90 the natural choice for buyers focused on engine & performance.
