Safety

For enhanced safety, the front, middle and rear (child comfort guides) seat shoulder belts of the GMC Yukon XL 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 XL 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 XL 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 XL and the Discovery have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all-wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

The GMC Yukon XL weighs 694 to 1214 pounds more than the Land Rover Discovery. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

GMC’s powertrain warranty covers the Yukon XL 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 10 times as many GMC dealers as there are Land Rover dealers, which makes it much easier should you ever need service under the Yukon XL’s warranty.

Reliability

The Yukon XL has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Discovery doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that GMC vehicles are better in initial quality than Land Rover vehicles. J.D. Power ranks GMC 20th in initial quality. With 61 more problems per 100 vehicles, Land Rover is ranked 31st.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that GMC vehicles are more reliable than Land Rover vehicles. J.D. Power ranks GMC 18th in reliability. With 48 more problems per 100 vehicles, Land Rover is ranked 30th.

Engine

The Yukon XL’s standard 5.3 V8 produces 15 more horsepower (355 vs. 340) and 51 lbs.-ft. more torque (383 vs. 332) than the Discovery’s 3.0 supercharged V6. The Yukon XL Graphite Performance Edition/Denali’s standard 6.2 V8 produces 80 more horsepower (420 vs. 340) and 128 lbs.-ft. more torque (460 vs. 332) than the Discovery’s 3.0 supercharged V6.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Yukon XL’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 XL uses regular unleaded gasoline (premium recommended on Yukon XL Graphite Performance Edition/Denali for maximum performance). The Discovery requires premium, which can cost 20 to 55 cents more per gallon.

The Yukon XL has 8.5 gallons more fuel capacity than the Discovery Diesel’s standard fuel tank (31 vs. 22.5 gallons), for longer range between fill-ups. The Yukon XL has 7.5 gallons more fuel capacity than the Discovery Gas’ standard fuel tank (31 vs. 23.5 gallons).

The Yukon XL has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Discovery doesn’t offer a cap-less fueling system.

Transmission

A ten-speed automatic is standard on the GMC Yukon XL Graphite Performance Edition/Denali, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Discovery.

Brakes and Stopping

The Yukon XL stops much shorter than the Discovery:

Tires and Wheels

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

The GMC Yukon XL’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 XL 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 XL 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.

Suspension and Handling

The Yukon XL 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 Discovery’s suspension doesn’t offer adjustable shock absorbers.

The Yukon XL offers an optional automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The Discovery doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Yukon XL’s wheelbase is 15 inches longer than on the Discovery (130 inches vs. 115 inches).

For better handling and stability, the track (width between the wheels) on the Yukon XL is 2.2 inches wider in the front and 2.2 inches wider in the rear than the average track on the Discovery.

The Yukon XL Denali 4x4 handles at .76 G’s, while the Discovery HSE Luxury pulls only .69 G’s of cornering force in a Motor Trend skidpad test.

The Yukon XL Denali 4x4 executes Motor Trend’s “Figure Eight” maneuver quicker than the Discovery HSE Luxury (28.4 seconds @ .64 average G’s vs. 29 seconds @ .59 average G’s).

Chassis

The Yukon XL Graphite Performance Edition//Denali uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Discovery doesn’t offer active noise cancellation.

The Yukon XL’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The Discovery’s rear cargo window doesn’t open.

Ergonomics

The Yukon XL has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Discovery doesn’t offer a remote starting system.

The Yukon XL’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.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Yukon XL has standard extendable sun visors. The Discovery doesn’t offer extendable visors.

The Yukon XL has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Discovery doesn’t offer a house-current electrical outlet.

Model Availability

The Yukon XL is available in both rear-wheel drive and four-wheel drive configurations. The Discovery doesn’t offer a two-wheel drive configuration.
