To lower fuel costs and make buying fuel easier, the Acura RDX uses regular unleaded gasoline (premium recommended for maximum performance). The RX 450hL requires premium, which can cost 20 to 55 cents more per gallon.

The RDX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The RXL doesn’t offer a cap-less fueling system.

For better traction, the RDX A-Spec’s tires are larger than the largest tires available on the RXL (255/40R20 vs. 235/65R18).

The RDX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the RXL’s standard 65 series tires. The RDX A-Spec’s tires have a lower 40 series profile than the RXL’s optional 55 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the RXL.

The RDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The RXL doesn’t offer vehicle monitored tire inflation.

The RDX offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The RXL’s suspension doesn’t offer adjustable shock absorbers.

The RDX AWD handles at .81 G’s, while the RX 350L AWD pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The RDX AWD executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the RX 350L (27.2 seconds @ .64 average G’s vs. 28.5 seconds @ .6 average G’s).

For greater off-road capability the RDX has a greater minimum ground clearance than the RXL (8.2 vs. 8.1 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

The Acura RDX may be more efficient, handle and accelerate better because it weighs about 700 to 850 pounds less than the Lexus RXL.

The RDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The RXL doesn’t offer active noise cancellation.
