Safety

The Macan has standard Multi-collision Brake System, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLC doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Macan. But it costs extra on the GLC.

When descending a steep, off-road slope, the Macan’s standard Porsche Hill Control allows you to creep down safely. The GLC doesn’t offer Porsche Hill Control.

Both the Macan and the GLC have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, blind spot warning systems and around view monitors.

Warranty

The Macan’s corrosion warranty is 7 years longer than the GLC’s (12 vs. 5 years).

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Porsche fourth in initial quality, above the industry average. With 13 more problems per 100 vehicles, Mercedes is ranked 14th.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 47 more problems per 100 vehicles, Mercedes is ranked 15th.

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

Engine

The Macan’s standard 2.0 turbo 4 cyl. produces 7 more horsepower (248 vs. 241) than the GLC 300’s standard 2.0 turbo 4 cyl.

Fuel Economy and Range

The Macan has 2.4 gallons more fuel capacity than the GLC (19.8 vs. 17.4 gallons), for longer range between fill-ups.

Transmission

The Macan offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The GLC doesn’t offer an SMG or a conventional manual transmission.

The Macan’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The GLC doesn’t offer launch control.

Tires and Wheels

For better traction, the Macan’s optional tires are larger than the largest tires available on the GLC (F:265/40R21 & R:295/35R21 vs. F:255/45R20 & R:285/40R20).

The Macan’s standard 255/55R18 rear tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the GLC’s standard 60 series tires. The Macan’s optional 265/40R21 front and 295/35R21 rear tires have a lower 40 series front and 35 series rear profile than the AMG GLC 43’s 45 series front and 40 series rear tires.

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

The Macan has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLC; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

For greater off-road capability the Macan has a 3 inches greater minimum ground clearance than the GLC 300 (8 vs. 5 inches), allowing the Macan to travel over rougher terrain without being stopped or damaged. The Macan’s minimum ground clearance is 2.3 inches higher than on the AMG GLC 43 (9 vs. 6.7 inches).

Towing

The Macan’s standard towing capacity is much higher than the GLC’s (4409 vs. 3500 pounds).

Servicing Ease

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