There is only one powertrain available for the 2018 Acura RDX. The crossover is powered by a 3.5-liter port-injection V6 engine. The unit produces 279 hp at 6,200 rpm and 252 lb-ft of torque at 4,900 rpm. The auto comes in front-wheel drive and all-wheel drive systems. The power is distributed via a 6-speed automatic transmission with Sequential SportShift Paddle Shifters. We found the transmission of the RDX to be smooth whether in Drive or Sport mode. Drive mode puts emphasis on fuel efficiency while providing a smooth automatic transmission. Sport mode provides manual control for the driver and quick acceleration during a high-performance run. Then, the Grade Logic Control helps in managing the transmission at lower gears during steep uphills and downhills. The steering of the RDX is precise because of its electric power assist and stiffer mounts. On the other hand, its handling is also improved , especially in slippery surfaces, in its all-wheel drive version with Intelligent Control. Moreover, the braking features of the crossover performed at an average with its shortest stop from 60 mph at 122 ft.

The Acura RDX sits in the luxury crossover SUV segment. The four-door vehicle bears a striking resemblance with the Honda CR-V. However, being a luxury vehicle, the RDX has smoother-looking surfaces with no stiff body lines. Also, it has redesigned roofrails, bumpers, wheels, lights, front radiator grille and logo. For its price though, it lacks some of the more advanced offerings of its rivals in the market. The 2018 RDX features 18-inch wheels, sunroof, premium vinyl upholstery, and leather-wrapped steering wheel. The Technology package upgrades the SUV's leather upholstery while the Advance package adds fog lights.
The 2018 RDX can accommodate up to five people. We found the interior of the crossover visually satisfying, although it lacks many of the opulent amenities available in its rivals from other luxury vehicle brands. The seat cushions felt firm but the padding and ventilation helps the people in its cabin have a relaxing experience even at long trips. The suspension setup aids a lot in mitigating the inconveniences brought about by bumps along the road. Furthermore, noise and vibrations from the outside are kept at a low level inside.
With the second row of seats up, the RDX can hold 26.1 cu-ft of cargo. This can be increased to 61.3 cu-ft. when the second-row seats are folded.
