RDX vs. XT5: Style and Sport

Acura RDX

Now in its third generation, the 2021 Acura RDX is handsome, practical, dependable, and a great value for the money. Power comes from a sole engine and transmission choice, but it’s plenty to keep the crossover moving. The base 2021 RDX is front-wheel drive, but Super Handling All-Wheel Drive is a $2,000 option. Space is generous for passengers front and rear, and with all seats folded the RDX has nearly 60 cubic feet of cargo space.

Standard features are abundant and include keyless entry, an ultra-wide panoramic sunroof, dual-zone automatic climate control, and heated and 12-way power-adjustable front seats. Also included are Wi-Fi, a 10.2-inch display, Apple CarPlay and Android Auto compatibility, satellite radio, and a 9-speaker/350-watt premium audio system.

All trims also include the AcuraWatch suite of safety features that includes automatic emergency braking, adaptive cruise control, lane-keeping assist, and more.

Any extras are bundled in packages, such as the Technology package with navigation, leather upholstery, a 12-speaker ELS audio system, and some other safety features. A-Spec adds some cosmetic changes and bigger wheels, and the Advance package adds a head-up display, 360-degree camera system, heated rear seats, and 16-way power-adjustable front seats.

The RDX may lack the brand cachet of some of its competitors, but its pricing is competitive and Acura boasts a reputation for quality and high resale value.

Cadillac XT5

A 5-seat luxury SUV, the 2021 Cadillac XT5 is large for a compact, with dimensions more akin to a midsize. As expected from a Cadillac, the exterior has a look that’s assertive without being over the top, and its interior is quiet and elegant. Materials are top quality, and the fit and finish are excellent.

It’s also very comfortable, with a sliding second-row seat for increased legroom. Cargo space is good, with 30 cubic feet behind that second row expanding to 63 with it folded.

The base engine is a 2.0-liter turbocharged 4-cylinder that sends power to the front wheels via a 9-speed automatic transmission. All-wheel drive is a $2,000 option in the base and second-tier Premium Luxury trims. We’re big fans of the top Sport trim, though, with a 3.6-liter V6, a sophisticated all-wheel-drive system, and an adaptive sport suspension that makes the Caddy a lot of fun to drive.

Standard features include simulated leather upholstery, heated front seats, wireless Apple CarPlay/Android Auto, Bluetooth, satellite radio, four USB ports, Wi-Fi, and an 8-speaker Bose audio system. Standard driving aids include forward-collision warning with automatic braking, lane departure warning, and a safety alert seat. One knock against the XT5 is that other driver assistance and safety features are not available on the base trim.


Optional all-wheel drive; fuel economy; warranty; NHTSA 5-Star safety rating.

Which One is Right for Me?

If sporty driving manners and top-notch build quality are your thing, the 2021 Acura RDX is a great choice, with a starting price about $4,500 lower than that of the XT5.

If pure luxury and power are your thing, the 2021 XT5 is a great choice, with that powerful upgrade V6 and comfortable leather upholstery throughout. But the top XT5 Sport trim with the V6 can reach the $65,000 range.
