Key Differences
-
The E-Class has better fuel economy
It’s a small lead (28 mpg versus 26 mpg), but it’s real, and it goes to the E-Class. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The E-Class has 22 lb-ft more torque
The A6 isn’t far behind at 273 lb-ft, but the E-Class’s 295 lb-ft still comes out ahead. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
-
The E-Class has better highway fuel economy
A narrow win for the E-Class. With 33 mpg to 31 mpg, it’s the kind of difference that adds up rather than stands out. Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.
Design & Size
Engine & Performance
E-Class leads
This area is close, with the E-Class just ahead of the A6. On its side, the E-Class has 22 lb-ft more torque. Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type. If engine & performance is your priority, the E-Class is the car to pick.
Torque
A6: 273 lb-ft E-Class: 295 lb-ft The E-Class’s extra torque makes it more relaxed when fully loaded or towing.
Fuel Economy & Range
E-Class leads
Look at the fuel economy & range table and one name keeps coming out on top: the E-Class. The E-Class has the edge with better fuel economy. The E-Class uses less fuel on the standard combined cycle, which matters most if you drive a lot. For anyone who cares most about fuel economy & range, the E-Class is the safer choice.
Fuel economy (combined)
A6: 26 mpg E-Class: 28 mpg Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
Fuel economy (highway)
A6: 31 mpg E-Class: 33 mpg Highway fuel economy matters if you cover long distances at steady speeds.
Space & Practicality
Too close to call
This is a tie in all but name. On space & practicality, both deliver about the same. Either car will serve you equally well on space & practicality.
Off-road & Towing
Too close to call
Neither the A6 nor the E-Class has a real advantage in the off-road & towing category. This section won’t settle the choice, so weigh the other areas more heavily.
