2026 Acura RDX vs 2026 Audi Q5: 10 Differences That Make RDX Stand Out in Ontario
Shopping for a premium compact SUV in Ontario usually comes down to two names: the Acura RDX and the Audi Q5. Both wear sport-luxury badges, both run turbocharged engines, and both put power to all four wheels standard.
The differences show up once you get past the badge, in how each SUV puts its standard equipment together. Here are 10 of them, drawn from each automaker's own specification sheets, to help narrow the choice before a test drive.
RDX vs. Q5 at a Glance
| Spec | RDX | Q5 |
|---|---|---|
| Horsepower | 272 hp | 268 hp |
| Curb Weight | 1,800 kg | 1,910 kg |
| Cargo (Behind Rear Seats) | 835 L | 780 L |
| Cargo (Seats Folded) | 1,668 L | 1,612 L |
| Drivetrain | SH-AWD (standard) | Quattro AWD (standard) |
| Transmission | 10-speed automatic | 7-speed dual-clutch |
| Torque | 280 lb-ft | 295 lb-ft |
| Fuel Economy (Combined) | 9.9 L/100 km | 9.7 L/100 km |
1. Standard All-Wheel Drive Systems
The 2026 RDX comes standard with Super Handling All-Wheel Drive (SH-AWD), a torque-vectoring system that sends up to 70% of engine torque rearward and can route up to 100% of that power to a single rear wheel to sharpen cornering. The Q5's standard quattro all-wheel drive uses a longitudinal layout with a five-link suspension front and rear to keep all four wheels driven.
Both are standard from the base trim, but SH-AWD's active torque vectoring gives the RDX a more engaged feel through corners in every season.
2. Turbocharged Engine Output
Both SUVs start with a 2.0-litre turbocharged inline-four, but the outputs land differently. The RDX's engine makes 272 hp at 6,500 rpm and 280 lb-ft of torque between 1,600 and 4,500 rpm, while the Q5 makes 268 hp and 295 lb-ft. The Q5 holds a torque edge, but the RDX answers with more horsepower from its mono-scroll turbo, backed by SH-AWD to put that power down through corners as well as in a straight line.
3. Transmission and Shift Feel
The RDX pairs its engine with a 10-speed automatic and standard steering-wheel paddle shifters, giving the driver more ratios to hold power in its optimal range. The Q5 uses a 7-speed S tronic dual-clutch transmission, favouring quick, direct shifts over the RDX's broader gear spread. Neither approach is wrong, but the RDX's extra gears keep the turbo engine closer to its torque peak more often, useful for merging onto Ontario highways or working through stop-and-go traffic.
4. Fuel Economy Ratings
The Q5 posts a combined rating of 9.7 L/100 km, edging out the RDX's 9.9 L/100 km. It's a narrow gap, and the RDX closes it with 4 more horsepower and the cornering benefit of its standard torque-vectoring SH-AWD system. For most Ontario commutes, the difference between the two ratings amounts to a few dollars a month at the pump, not enough to outweigh the RDX's added engagement.
5. Cargo Space Behind the Rear Seats and Folded Flat
Measured behind the rear seats, the RDX holds 835 L of cargo, more than the Q5's 780 L in the same configuration. Fold the rear seats down and the gap holds: the RDX expands to 1,668 L against the Q5's 1,612 L. For Ontario households hauling hockey bags, strollers, or a grocery run, that extra room behind the seats matters more day to day than folding flat, since most cargo trips don't involve folding seats at all.
6. Standard Screens and Connectivity
The Q5 fits a 14.5-inch MMI touchscreen and an 11.9-inch virtual cockpit display standard across every trim, larger than the RDX's 10.2-inch HD centre display and 7-inch metre display. The RDX's base trim still runs a full standard connectivity list: Wi-Fi hotspot capability, Amazon Alexa Built-in, HD Radio, SiriusXM, and AcuraLink Connected Services, all controlled through the brand's True Touchpad Interface. The Q5's displays are larger, but the RDX matches its connected-services depth from the base trim, screen size aside.
7. Lighting Signatures
Every RDX trim, including the base model, comes standard with Jewel Eye LED headlights, Chicane LED daytime running lights, and LED taillights, brake lights, and cargo lights. The Q5 TFSI starts with standard LED headlights and taillights with dynamic turn signals, and moving to Progressiv or Technik adds matrix-design LED headlights and animated taillights. The RDX's full lighting signature is standard from the first trim, while the Q5 buyer moves up the lineup for its most advanced lighting hardware.
8. Standard vs. Trim-Gated Comfort Features
Both SUVs put heated front seats on every trim. From there, the paths split: Q5 Progressiv and Technik add heated rear seats and a panoramic moonroof that the base TFSI trim does not include, while the RDX gates ELS Studio 3D Premium Audio, Acura Navigation with 3D view, wireless phone charging, and Iconic Drive ambient lighting behind its A-SPEC trim and up.
Neither brand hands over its full comfort list at the entry trim, but the RDX's A-SPEC step pairs those upgrades with a sport-tuned interior package in the same move.
9. Curb Weight and Footprint
The RDX carries a curb weight of 1,800 kg, lighter than the Q5's 1,910 kg despite similar footprints: the RDX stretches 4,766 mm long on a 2,750 mm wheelbase, while the Q5 measures 4,717 mm long on a longer 2,820 mm wheelbase. That lighter curb weight works with the RDX's SH-AWD system to keep its sport-luxury character intact, and rear-seat riders get 975 mm of legroom in the RDX for stretching out on longer drives.
10. Exterior Colour and Trim Presentation
The base RDX offers three exterior colours: Platinum White Pearl, Majestic Black Pearl, and Solar Silver Metallic. Stepping up to RDX A-SPEC unlocks the full seven-colour palette, including Liquid Carbon Metallic, Urban Grey Pearl, Apex Blue Pearl, and Performance Red Pearl, paired with Ultrasuede-trimmed leather interiors. The Q5 offers additional exterior paint finishes as options on top of its standard palette. The RDX ties its boldest colours to a performance-oriented trim; the Q5 treats paint mostly as a standalone choice.
Why the RDX Fits Ontario Drivers
For drivers who want standard torque-vectoring AWD, a torque-y turbo engine, and more cargo room behind the rear seats without waiting for a higher trim, the RDX delivers all three from its base configuration. The 10-speed automatic keeps the 272-hp engine in its power band, and the cabin backs it up with a full standard connectivity list rather than a bigger screen alone.
Ontario buyers cross-shopping this segment for daily comfort and all-weather confidence get an SUV that doesn't ask them to move up the lineup just to feel equipped. The RDX's standard equipment list, paired with SH-AWD's active torque vectoring, makes it the sportier, better-equipped choice at its starting point in the lineup.
