A powerful, elegant, and stylish SUV.

There are quite a few five-passenger SUVs on the market that will do the job of carrying people and cargo, but few do it with the style of the 2021 Acura RDX. Its sleek exterior gives this car loads of curb appeal and its roomy and well-appointed interior creates a welcome space. The RDX has a powerful turbocharged engine that engages the driver and a smooth, quiet ride that passengers enjoy no matter how rough the road. Redesigned for the 2019 model year, this design carries over into 2021 with the addition of the new PMC Edition. This limited edition of 360 units features exclusive Thermal Orange Pearl paint and comes equipped with both the A-Spec and Advance Package.

5 reasons to buy the 2021 Acura RDX

1. Smooth and luxurious

2021 Acura RDX Review: Dashboard | CarMax

As a luxury SUV, the 2021 Acura RDX offers a very comfortable ride. It has a quiet interior that keeps the outside world from intruding into the cabin and a suspension system that evens out rough roads. Seating is supportive no matter where you sit, with beautiful materials and plenty of soft-touch surfaces that put the priority on passenger comfort.

2. Super handling all-wheel drive

2021 Acura RDX Review: Exterior | CarMax

The 2021 Acura RDX is available with standard front-wheel-drive or optional Super Handling All-Wheel Drive. If you look for an RDX with all-wheel-drive, you'll find it not only makes it a more capable SUV in poor weather conditions, but it also enhances performance in dry weather. The all-wheel drive system adjusts torque to each wheel to improve traction and increase overall stability in all conditions.

3. Cargo room

Room for cargo is no doubt a priority if you're looking for an SUV and the 2021 Acura RDX is up to the challenge. There is 29.5 cu ft of space behind the rear seat, so even with a full load of passengers it can handle plenty of cargo. The rear seats are also 60/40 split-folding to offer more versatility for cargo while still allowing for rear passengers. Cargo room increases to 58.9 cu ft with the rear seats fully folded.

4. Concise trim lineup

There aren't technically trims of the 2021 Acura RDX, but rather a single configuration with three available packages. The A-Spec package adds sporty design elements and the Advance package adds convenience features. The Technology package draws from both of those packages and upgrades audio. Even the limited PMC Edition comes in a single configuration with both the A-Spec and Advance packages as standard features.

5. Responsive engine

The turbocharged 2.0L engine in the 2021 Acura RDX delivers an engaging driving experience. It responds quickly to a light foot on the accelerator so merging with highway traffic is effortless. The engine is paired with a 10-speed automatic transmission that delivers power easily with smooth shifting. It has the power to inspire confidence behind the wheel without any of the harshness found in purely performance-focused vehicles.
