The 2026 Acura RDX starts at $45,100 with 272 horsepower, standard SH-AWD with torque vectoring and a standard panoramic moonroof. The 2026 BMW X3 xDrive30 starts at $50,900 with 255 horsepower and xDrive without torque vectoring. The RDX is about $5,800 less with more power and a longer warranty.
The X3 is the default answer in the compact luxury SUV segment, and it earns that on driving dynamics. The RDX is the one that keeps turning up on the shortlist because it is cheaper, more powerful and more generously equipped.
Here is what actually separates them, including where the BMW is worth the difference.

272 horsepower against 255, with ten transmission ratios against eight. The RDX turbo four is the stronger engine on paper and the more responsive one at the top of the rev range.
The bigger mechanical difference is what happens in a corner. SH-AWD is standard on every RDX and it overdrives the outside rear wheel to help the vehicle turn. BMW’s xDrive is a well-sorted all-wheel-drive system, but it does not vector torque across the rear axle. On a road like Latrobe or the run down to Ione, that difference is something you feel rather than read.
| Specification | RDX | X3 |
|---|---|---|
| Horsepower | 272 hp | 255 hp |
| Transmission | 10-speed | 8-speed |
| AWD torque vectoring | Standard with SH-AWD | Not offered |
Front legroom is 42.0 inches in the RDX against 40.2 in the X3; rear legroom is 38.0 against 36.3. Nearly two inches in both rows is a real difference for taller drivers and for rear-facing car seats.
The panoramic moonroof is standard on the RDX and optional on the X3. Heated front seats and Walk Away Auto Lock are standard on the RDX and cost extra on the BMW. The multi-view rear camera is standard on the RDX and lives inside an expensive package on the X3.
The RDX also has Acura’s True Touchpad Interface, an absolute-position touchpad that maps to the screen rather than sliding like a laptop trackpad. It is genuinely different and worth trying — some people love it, some do not, and it is better to find out in the showroom.
| Specification | RDX | X3 |

| Rear legroom | 38.0 in | 36.3 in |

| Heated front seats | Standard | Extra cost |
| Multi-view rear camera | Standard | Extra-cost package |
The RDX starts at $45,100 against $50,900 for the X3 xDrive30 — about $5,800 before you add the moonroof, heated seats and camera package that bring the BMW up to RDX-standard equipment.
Acura covers the powertrain for 6 years or 70,000 miles; BMW for 4 years or 50,000 miles.
| Specification | RDX | X3 |

| Base MSRP | $45,100 | $50,900 |
| Powertrain limited warranty | 6 years / 70,000 miles | 4 years / 50,000 miles |
The X3 is the better-driving vehicle for an enthusiast. Its rear-drive-biased chassis, steering weighting and body control are a step above, and the X3 M50 above it is a genuinely fast SUV with no RDX equivalent.
BMW interior ergonomics and the current iDrive system are excellent, and the X3 offers a more configurable digital instrument display.
BMW includes a period of scheduled maintenance on new vehicles, which offsets some of the early ownership cost difference.
The RDX is the better buy for most people cross-shopping these two: more power, more room, more standard equipment, torque-vectoring all-wheel drive and about $5,800 less to start.
The X3 is the better buy if driving feel is your priority and you are willing to pay for it — and if you want the performance variants above it.
Try the True Touchpad Interface before you decide either way. It is the one thing on this list that people react to strongly.
Yes. The 2026 RDX starts at $45,100 and the X3 xDrive30 starts at $50,900, a difference of about $5,800 before options. The panoramic moonroof, heated seats and multi-view camera that are standard on the RDX are extra-cost items on the X3.
The RDX makes 272 horsepower at 6,500 rpm. The X3 xDrive30 makes 255 horsepower. The RDX also uses a 10-speed automatic against the X3’s 8-speed.
xDrive distributes torque between the front and rear axles but does not vector torque across the rear axle. Acura’s standard SH-AWD overdrives the outside rear wheel through a corner to help rotate the vehicle.
It has more legroom in both rows: 42.0 inches front and 38.0 inches rear, against 40.2 and 36.3 in the X3.
It is Acura’s absolute-position touchpad controller. Unlike a laptop trackpad, each point on the pad maps directly to a point on the screen, so you touch where you want to go rather than dragging a cursor. BMW does not offer a comparable system.
