Key Differences
-
The A5 has 119 hp more power
Not a close call. The A5 lists 268 hp and the Ioniq 6 lists 149 hp. That’s a substantial gap. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The A5 has 37 lb-ft more torque
The A5 is slightly stronger on torque. The gap, 295 lb-ft versus 258 lb-ft, won’t change your life, but it isn’t nothing. Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type.

Space & Practicality
Too close to call
Evenly matched is the fairest summary of the space & practicality section. Don’t let space & practicality decide this one; look at the other sections instead.
Off-road & Towing
Too close to call
Call the off-road & towing round a draw. So off-road & towing is a non-factor here; move on to the areas where they actually differ.
Safety & Tech
This area doesn’t reduce to a single number. The table shows the safety & tech details for both, so you can judge what matters to you.
