The GLE 450’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Terrain are solid, not vented.

Tires and Wheels

For better traction, the GLE has larger standard tires than the Terrain (255/50R19 vs. 225/65R17). The GLE’s optional tires are larger than the largest tires available on the Terrain (F:275/45R21 & R:315/40R21 vs. 235/50R19).

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 Terrain’s standard 65 series tires. The GLE’s optional 275/45R21 front and 315/40R21 rear tires have a lower 45 series front and 40 series rear profile than the Terrain’s optional 50 series tires.

For better ride, handling and brake cooling the GLE has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Terrain. The GLE’s optional 21-inch wheels are larger than the 19-inch wheels optional on the Terrain.

Suspension and Handling

The GLE has standard front and rear stabilizer bars, which help keep the GLE flat and controlled during cornering. The Terrain’s suspension doesn’t offer a rear stabilizer bar.

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

The GLE offers an available 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 Terrain’s suspension doesn’t offer adjustable shock absorbers.

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 Terrain 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 Terrain doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 10.6 inches longer than on the Terrain (117.9 inches vs. 107.3 inches).

For better handling and stability, the track (width between the wheels) on the GLE is 3.8 inches wider in the front and 4.3 inches wider in the rear than on the Terrain.

Passenger Space

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

The GLE has .5 inches more front headroom, 2.1 inches more front shoulder room, 1.1 inches more rear headroom, 1.2 inches more rear legroom and 2.7 inches more rear shoulder room than the Terrain.

Cargo Capacity

The GLE has a much larger cargo volume with its rear seat up than the Terrain with its rear seat up (33 vs. 29.6 cubic feet). The GLE has a much larger cargo volume with its rear seat folded than the Terrain with its rear seat folded (75 vs. 63.3 cubic feet).

Towing

The GLE’s standard towing capacity is much higher than the Terrain’s (7700 vs. 1500 pounds).

Servicing Ease

The engine in the GLE is mounted longitudinally (North-South), instead of sideways, as in the Terrain. 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 GMC. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 30% lower rating, GMC is ranked 14th.

Ergonomics

Unlike the driver-only memory seat and mirrors optional at extra cost in the Terrain (except SL/SLE), 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 offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Terrain doesn’t offer a heads-up display.

If the windows are left open on the GLE the driver can close them all from a distance using the remote (remote must be aimed at door sensor). On a hot day the driver can also lower the windows the same way. The driver of the Terrain can only close the windows from inside the vehicle, with the ignition on.

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 Terrain’s manually variable intermittent wipers have to be constantly adjusted.

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 Terrain doesn’t offer cornering lights.

The GLE has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Terrain and isn’t available on the Terrain SL.

The GLE’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Terrain SL doesn’t offer automatic air conditioning.

The GLE’s standard GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Terrain’s available navigation system doesn’t offer real-time traffic updates.

The GLE’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Terrain Denali’s automatic parking system requires operating the brakes and transmission to safely park.
