Regenerative brakes improve the GLE 450’s fuel efficiency by converting inertia back into energy instead of wasting it. The RDX doesn’t offer a regenerative braking system.

The GLE has 5.4 gallons more fuel capacity than the RDX (22.5 vs. 17.1 gallons), for longer range between fill-ups.

For better traction, the GLE has larger standard tires than the RDX (255/50R19 vs. 235/55R19). The GLE’s optional tires are larger than the largest tires available on the RDX (F:275/45R21 & R:315/40R21 vs. 255/40R20).

The GLE’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the RDX’s standard 55 series tires.

For better ride, handling and brake cooling the GLE offers optional 21-inch wheels. The RDX’s largest wheels are only 20-inches.

The GLE 450 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Acura doesn’t offer an active suspension on the RDX.

The GLE has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLE’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The RDX doesn’t offer a load leveling suspension.

The GLE’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The RDX doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 9.6 inches longer than on the RDX (117.9 inches vs. 108.3 inches).

For better handling and stability, the track (width between the wheels) on the GLE is 1.9 inches wider in the front and 2.1 inches wider in the rear than on the RDX.

The GLE’s front to rear weight distribution is more even (53.5% to 46.5%) than the RDX’s (57% to 43%). This gives the GLE more stable handling and braking.

The GLE 450 handles at .84 G’s, while the RDX A-Spec AWD pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The GLE offers optional seating for 7 passengers; the RDX can only carry 5.

The GLE has .9 inches more front headroom, 1.3 inches more rear headroom, 2.5 inches more rear legroom and 1.7 inches more rear shoulder room than the RDX.

For enhanced passenger comfort on long trips the GLE’s middle row seats recline. The RDX’s rear seats don’t recline.

The engine in the GLE is mounted longitudinally (North-South), instead of sideways, as in the RDX. This makes it easier to service and maintain, because the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Acura. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 4% lower rating, Acura is ranked 6th.

Unlike the driver-only memory system in the RDX, the GLE offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLE’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The RDX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers see further while navigating curves, the GLE offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The RDX doesn’t offer cornering lights.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLE offers an optional wireless phone charging system (Qi) in the center console. The RDX doesn’t offer wireless personal charging.

The GLE offers an optional 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The RDX doesn’t offer a house-current electrical outlet.

The GLE’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The RDX doesn’t offer an automated parking system.
