Key Differences
-
The G70 has 99 hp more power
The numbers aren’t close. The G70 lists 300 hp for total system output, while the A4 lists 201 hp. The G70’s extra output gives it more in reserve when you need to get up to speed.
-
The A4 has better fuel economy
A clear win for the A4: 29 mpg against 24 mpg. Few specs in this matchup are as one-sided. The A4 uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The G70 has 75 lb-ft more torque
Here the G70 pulls well ahead of the A4, with 311 lb-ft compared to 236 lb-ft. The G70’s extra torque makes it more relaxed when fully loaded or towing.
-
The A4 has better highway fuel economy
The A4 doesn’t just edge this one; 36 mpg against 29 mpg is a lead you’ll feel. Highway fuel economy matters if you cover long distances at steady speeds.
-
The A4 has better city fuel economy
Big gap, real consequences. The A4’s 26 mpg versus the G70’s 21 mpg changes how the two compare in daily use. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.

Engine & Performance
G70 leads
In the engine & performance category, the G70 isn’t just ahead; it’s clearly ahead. In its favor, the G70 has 99 hp more power. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels. That makes the G70 the natural choice for buyers focused on engine & performance.
Total system output
A4: 201 hp G70: 300 hp More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
Torque
A4: 236 lb-ft G70: 311 lb-ft Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type.
Fuel Economy & Range
A4 leads
Here the A4 opens up one of its biggest leads in the comparison. The A4 delivers better fuel economy. Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold. If this section decides it for you, choose the A4.
Fuel economy (combined)
A4: 29 mpg G70: 24 mpg Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
Fuel economy (highway)
A4: 36 mpg G70: 29 mpg The A4 uses less fuel on the highway, a real saving on road trips and long commutes.
Space & Practicality
Too close to call
There’s no meaningful winner in the space & practicality section; the two are too close to separate. If space & practicality was going to be your tiebreaker, you’ll need a different one.
Off-road & Towing
Too close to call
Evenly matched is the fairest summary of the off-road & towing section. Treat off-road & towing as common ground and look elsewhere for the deciding factor.
Safety & Tech
For safety & tech, the spec sheet lists components and formats rather than figures we can rank. The table shows what the A4 and the G70 each bring.
