RDX vs GLC
Acura versus Mercedes-Benz: the RDX and the GLC go after the same compact luxury suv buyer. Surprisingly little separates them. A handful of specs move the needle; the rest are rounding errors.

Key Differences
-
The RDX has 17 hp more power
This one is close enough that other factors could outweigh it, but on paper the RDX leads with 272 hp to 255 hp. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The GLC has 15 lb-ft more torque
Only a little separates them: 295 lb-ft on the GLC, 280 lb-ft on the RDX. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
Design & Size
Engine & Performance
Trade-off
The RDX and the GLC split the engine & performance section, the RDX with 17 hp more power and the GLC with 15 lb-ft more torque. The takeaway: engine & performance is a matter of preference rather than a clear verdict.
Total system output
RDX: 272 hp GLC: 255 hp More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
Torque
RDX: 280 lb-ft GLC: 295 lb-ft Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type.
Space & Practicality
Too close to call
In the space & practicality category, the RDX and the GLC land in almost the same place. Both cover space & practicality well enough that other priorities should break the tie.
Off-road & Towing
Too close to call
Swap one for the other and you’d lose nothing on off-road & towing. Net result on off-road & towing: level.
