Safety

For enhanced safety, the front and middle seat shoulder belts of the Mercedes GLE have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Blazer doesn’t offer pretensioners for the middle seat belts.

The GLE’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Blazer doesn’t offer pre-crash pretensioners.

When descending a steep, off-road slope, the GLE’s standard Downhill Speed Regulation allows you to creep down safely. The Blazer doesn’t offer Downhill Speed Regulation.

The GLE’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Blazer doesn’t offer a driver alert monitor.

Both the GLE and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems and around view monitors.

The Mercedes GLE weighs 409 to 1209 pounds more than the Chevrolet Blazer. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The GLE comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Blazer’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The GLE’s corrosion warranty is unlimited miles longer than the Blazer’s (unlimited vs. 100,000 miles).

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Mercedes vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Mercedes 6 places higher in reliability than Chevrolet.

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

The GLE has 3.1 gallons more fuel capacity than the Blazer FWD’s standard fuel tank (22.5 vs. 19.4 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the GLE’s brake rotors are larger than those on the Blazer:

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 Blazer are solid, not vented.

Tires and Wheels

For better traction, the GLE has larger standard tires than the Blazer (255/50R19 vs. 235/65R18). The GLE’s optional tires are larger than the largest tires available on the Blazer (F:275/45R21 & R:315/40R21 vs. 265/45R21).

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 Blazer’s standard 65 series tires. The GLE’s optional 315/40R21 rear tires have a lower 40 series profile than the Blazer RS/Premier’s optional 45 series tires.

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

Suspension and Handling

The GLE has standard front and rear gas-charged shocks for better control over choppy roads. The Blazer’s suspension doesn’t offer gas-charged shocks.

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

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 Blazer’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 Blazer 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 Blazer doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 5.2 inches longer than on the Blazer (117.9 inches vs. 112.7 inches).

The GLE’s front to rear weight distribution is more even (53.5% to 46.5%) than the Blazer’s (60.1% to 39.9%). This gives the GLE more stable handling and braking.

Passenger Space

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

The GLE has .7 inches more front headroom, .2 inches more front shoulder room, 1 inch more rear headroom and 1.3 inches more rear legroom than the Blazer.

Cargo Capacity

The GLE has a much larger cargo volume with its rear seat up than the Blazer with its rear seat up (33 vs. 30.5 cubic feet). The GLE has a much larger cargo volume with its rear seat folded than the Blazer with its rear seat folded (75 vs. 64.2 cubic feet).

Towing

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

Servicing Ease

The engine in the GLE is mounted longitudinally (North-South), instead of sideways, as in the Blazer. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Chevrolet. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 25% lower rating, Chevrolet is ranked 13th.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the Blazer (except L/LT), 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 Blazer 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 Blazer 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 Blazer’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 Blazer doesn’t offer cornering lights.

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