For enhanced safety, the front and middle seat shoulder belts of the Land Rover Discovery 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 GMC Acadia doesn’t offer pretensioners for the middle seat belts.

Both the Discovery and Acadia have child safety locks to prevent children from opening the rear doors. The Discovery has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Acadia’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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

The Discovery’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 Acadia doesn’t offer a driver alert monitor.

Both the Discovery and the Acadia 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, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

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

The Discovery’s 6 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Acadia runs out after 100,000 miles.

The Discovery’s 3.0 supercharged V6 produces 110 more horsepower (340 vs. 230) and 74 lbs.-ft. more torque (332 vs. 258) than the Acadia’s optional 2.0 turbo 4 cyl. The Discovery’s 3.0 supercharged V6 produces 30 more horsepower (340 vs. 310) and 61 lbs.-ft. more torque (332 vs. 271) than the Acadia’s optional 3.6 DOHC V6.

The Discovery’s 3.0 turbo V6 diesel produces 61 more horsepower (254 vs. 193) and 255 lbs.-ft. more torque (443 vs. 188) than the Acadia’s standard 2.5 DOHC 4 cyl.

For better traction, the Discovery’s optional tires are larger than the largest tires available on the Acadia (285/40R22 vs. 255/65R17).

The Discovery’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia’s optional 55 series tires.

For better ride, handling and brake cooling the Discovery has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Acadia. The Discovery’s optional 22-inch wheels are larger than the 20-inch wheels optional on the Acadia.

The Discovery offers an optional full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Acadia, it requires you to depend on a temporary spare that has mileage and speed limitations, or roadside assistance and a tow-truck.

For a smoother ride and more stable handling, the Discovery’s wheelbase is 2.5 inches longer than on the Acadia (115 inches vs. 112.5 inches).

For better handling and stability, the average track (width between the wheels) on the Discovery is 2 inches wider in the front and 1.9 inches wider in the rear than the track on the Acadia.

For greater off-road capability the Discovery has a 1.5 inches greater minimum ground clearance than the Acadia (8.7 vs. 7.2 inches), allowing the Discovery to travel over rougher terrain without being stopped or damaged. The Discovery Air Suspension’s minimum ground clearance is 3.3 inches higher than on the Acadia All Terrain (11.1 vs. 7.8 inches).

Flexibility is maximized at the game, campground or a drive-in theatre in the Discovery when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The Acadia doesn’t offer tailgating seats.

Both the Discovery and the Acadia offer second row automatic folding seats. The Discovery’s optional third row seats also fold up or down at the press of a button. The Acadia doesn’t offer automatic folding third row seats.

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

Unlike the driver-only memory seat and mirrors optional at extra cost in the Acadia (except SL/SLE/AT4), the Discovery HSE/HSE Luxury has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Discovery HSE/HSE Luxury 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 Acadia doesn’t offer a heads-up display.

The Discovery’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Acadia’s rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the Discovery the driver can close them all from a distance using the remote. The driver of the Acadia can only operate the windows from inside the vehicle, with the ignition on.

The Discovery has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Acadia doesn’t offer a locking fuel door.

The Discovery’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 Acadia’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are optional on the Discovery to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Acadia doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Discovery offers available headlight washers to keep headlight output high. The Acadia doesn’t offer headlight washers.

To help drivers see further while navigating curves, the Discovery HSE/HSE Luxury offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Acadia doesn’t offer cornering lights.

The Discovery offers optional heated front, second and third row seats that keep the driver and passengers extremely comfortable in the winter. GMC doesn’t offer heated seats in the third row of the Acadia.

Optional air-conditioned the front and second row seats keep the Discovery’s passengers comfortable and take the sting out of hot leather in summer. The Acadia doesn’t offer air-conditioned seats for the second row.

The Discovery’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Acadia doesn’t offer an automated parking system.

The Discovery will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Discovery will retain 47.79% to 49.86% of its original price after five years, while the Acadia only retains 35.93% to 45.86%.
