For enhanced safety, the front seat shoulder belts of the GMC Yukon are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Land Rover Discovery doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Yukon are reminded to check the back seat if they opened the rear door before starting out. The Discovery doesn’t offer a back seat reminder.

The Yukon has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Discovery doesn’t offer front seat center airbags.

Both the Yukon and the Discovery have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

GMC’s powertrain warranty covers the Yukon 1 year and 10,000 miles longer than Land Rover covers the Discovery. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Discovery ends after only 4 years or 50,000 miles.

There are over 9 times as many GMC dealers as there are Land Rover dealers, which makes it much easier should you ever need service under the Yukon’s warranty.

An engine control system that can shut down some of the engine’s cylinders helps improve the Yukon V8’s fuel efficiency. The Discovery doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the GMC Yukon uses regular unleaded gasoline (premium recommended on Yukon Denali for maximum performance). The Discovery requires premium, which can cost 20 to 55 cents more per gallon.

For better traction, the Yukon has larger standard tires than the Discovery (265/65R18 vs. 235/65R19).

The GMC Yukon’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Land Rover Discovery only has 5 wheel lugs per wheel.

The Yukon 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 Discovery doesn’t offer vehicle monitored tire inflation.

The Yukon has a standard full size spare so a flat doesn’t interrupt your trip. A full size spare costs extra on the Discovery. Without the option you must depend on a temporary spare, which limits mileage and speed before replacement.

For a smoother ride and more stable handling, the Yukon’s wheelbase is 5.9 inches longer than on the Discovery (120.9 inches vs. 115 inches).

The Yukon’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Discovery does not have an oil pressure gauge.
