Key Differences
-

Slight advantage to the 7 Series: 28 mpg compared with 25 mpg. Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
-
The 7 Series has 40 hp more power
On total system output, the 7 Series edges out the A7, 375 hp to 335 hp. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The 7 Series has better city fuel economy
Don’t expect a night-and-day difference here. 25 mpg against 22 mpg is a small but genuine lead for the 7 Series. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
Design & Size
Engine & Performance
7 Series leads
This area is close, with the 7 Series just ahead of the A7. On the 7 Series, you get 40 hp more power. The 7 Series’s extra output gives it more in reserve when you need to get up to speed. On engine & performance alone, the 7 Series gets the nod.

A7: 335 hp 7 Series: 375 hp More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
Fuel Economy & Range
7 Series leads
In the fuel economy & range category, the 7 Series isn’t just ahead; it’s clearly ahead. The 7 Series makes its case with better fuel economy. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership. Prioritize fuel economy & range, and the 7 Series is where you should land.
