The 2026 Acura RDX makes 272 horsepower against the Buick Envision’s 228, offers 79.8 cubic feet of maximum cargo space against 52.7, and includes SH-AWD with torque vectoring, a panoramic moonroof, heated front seats and a programmable power liftgate as standard — all extra-cost on the Envision.
The Envision is Buick’s value entry in the near-luxury compact SUV space, and it is a pleasant, quiet vehicle that undercuts most of the segment on price.
What the comparison shows is how much of the gap is made back once you equip the Buick to match.

Comparison uses the 2025 Envision, the most recent model year published by Acura for this pairing. Buick content and incentives change frequently.
44 horsepower is a wide margin in this class. The RDX turbo four makes 272 against the Envision’s 228, and it does it through a 10-speed rather than a 9-speed.
SH-AWD is standard on the RDX and adds torque vectoring across the rear axle. The Envision’s all-wheel drive distributes torque but does not vector it.

79.8 cubic feet against 52.7 is a 27-cubic-foot difference — more than half again as much space with the seats folded.
Heated front seats, the panoramic moonroof and the programmable power liftgate are all standard on the RDX and extra-cost items on the Envision. The driver’s seat is 12-way power against 8-way.

Acura is longer on both terms here. Basic coverage runs 4 years or 50,000 miles against Buick’s 3 years or 36,000 miles, and powertrain coverage runs 6 years or 70,000 miles against 5 years or 60,000.

The Envision is substantially less expensive, and GM incentive support on it is often strong. If the payment is the constraint, that is the argument.
Buick has invested heavily in cabin quietness and the Envision is genuinely serene at highway speed — noticeably so in back-to-back driving.
The Envision uses a conventional touchscreen with a large, clear display and straightforward menus. Buyers who dislike touchpad controllers will find it easier to live with.
The RDX leads on power, cargo, drivetrain, standard equipment and warranty term. Configure an Envision with the moonroof, heated seats and power liftgate and the price gap narrows considerably.
The Envision remains the choice if the discounted payment is materially lower and you do not need the extra cargo capacity or power.
If you are considering both, the cargo difference is the one to verify in person — 27 cubic feet is hard to picture from a brochure.
The 2026 Acura RDX makes 272 horsepower. The 2025 Buick Envision makes 228 horsepower — a difference of 44 horsepower.
The RDX offers 79.8 cubic feet of maximum cargo volume against 52.7 cubic feet in the Envision.
It is an extra-cost item on the Envision. A power panoramic moonroof is standard on every 2026 Acura RDX, as are heated front seats and a programmable power liftgate.
Acura is longer on both terms: 4 years or 50,000 miles basic against 3 years or 36,000, and 6 years or 70,000 miles powertrain against 5 years or 60,000.
Yes, the Envision typically carries a lower starting price and stronger incentives. Equip it with the moonroof, heated seats and power liftgate that the RDX includes and the gap narrows.
