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 Mazda CX-9 doesn’t offer pretensioners for the middle seat belts.

Both the Discovery and CX-9 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 CX-9’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 CX-9.

When descending a steep, off-road slope, the Discovery’s standard Hill Descent Control allows you to creep down safely. The CX-9 doesn’t offer Hill Descent Control.

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 CX-9 doesn’t offer a driver alert monitor.

Both the Discovery and the CX-9 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, 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 CX-9’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The Discovery’s corrosion warranty is 1 year longer than the CX-9’s (6 vs. 5 years).

On the EPA test cycle the Discovery Td6 gets better city fuel mileage than the CX-9 AWD (21 city/26 hwy vs. 20 city/26 hwy).

In heavy traffic or at stoplights the Discovery’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The CX-9 doesn’t offer an automatic engine start/stop system.

The Discovery Diesel’s standard fuel tank has 3.4 gallons more fuel capacity than the CX-9 FWD’s standard fuel tank (22.4 vs. 19 gallons), for longer range between fill-ups. The Discovery Gas’ standard fuel tank has 4.3 gallons more fuel capacity than the CX-9 AWD’s standard fuel tank (23.8 vs. 19.5 gallons).

For better traction, the Discovery’s optional tires are larger than the largest tires available on the CX-9 (285/40R22 vs. 255/60R18).

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 CX-9 Grand Touring/Signature’s 50 series tires.

For better ride, handling and brake cooling the Discovery has standard 19-inch wheels. Smaller 18-inch wheels are standard on the CX-9 Sport/Touring. The Discovery’s optional 22-inch wheels are larger than the 20-inch wheels on the CX-9 Grand Touring/Signature.

For better handling and stability, the average track (width between the wheels) on the Discovery is 1.3 inches wider in the front and 1.2 inches wider in the rear than the track on the CX-9.

For greater off-road capability the Discovery Air Suspension has a 2.3 inches greater minimum ground clearance than the CX-9 (11.1 vs. 8.8 inches), allowing the Discovery to travel over rougher terrain without being stopped or damaged.

The Discovery is 4.3 inches shorter than the CX-9, making the Discovery easier to handle, maneuver and park in tight spaces.

The front grille of the Discovery uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The CX-9 doesn’t offer active grille shutters.

The Discovery has .1 inches more front headroom, 1.1 inches more front hip room, 2.5 inches more front shoulder room, .5 inches more rear headroom, 1.4 inches more rear shoulder room, 2.5 inches more third row headroom, 3.8 inches more third row legroom and 1.9 inches more third row hip room than the CX-9.

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 CX-9 doesn’t offer tailgating seats.

The Discovery has a standard third row seat that folds flat into the floor. This completely clears a very large cargo area quickly. The CX-9 doesn’t offer seats that fold into the floor.

Pressing a switch automatically lowers or raises the Discovery’s optional second and third row seats, to make changing between cargo and passengers easier. The CX-9 doesn’t offer automatic folding seats.

To make loading groceries and cargo easier when your hands are full, the Discovery’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-9 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The Discovery uses gas struts to support the hood for easier service access. The CX-9 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the Discovery is mounted longitudinally (North-South), instead of sideways, as in the CX-9. This makes it easier to service and maintain, because the accessory belts are in front.

The Discovery has a maintenance free battery for long life without checking the battery’s water level. The CX-9 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

Unlike the driver-only memory seat in the CX-9 Grand Touring/Signature, 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’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The CX-9 doesn’t offer an easy entry system.

The power windows standard on both the Discovery and the CX-9 have locks to prevent small children from operating them. When the lock on the Discovery is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-9 prevents the driver from operating the other windows just as it does the other passengers.

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 CX-9 can only operate the windows from inside the vehicle, with the ignition on.

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 CX-9’s standard manually variable intermittent wipers have to be constantly adjusted.

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 CX-9 doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the Discovery’s headlight performance “Very Good,” a higher rating than the CX-9’s headlights that were rated “Fair.”

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 CX-9 doesn’t offer headlight washers.

The Discovery has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The CX-9 only offers an automatic headlight on/off feature as an extra cost option.

The Discovery’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda charges extra for heated mirrors on the CX-9.

When the Discovery HSE/HSE Luxury is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The CX-9’s mirrors don’t automatically adjust for backing.

The Discovery has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The CX-9 offers an automatic rear view mirror, but its side mirrors don’t dim.

The Discovery offers optional heated front, second and third row seats that keep the driver and passengers extremely comfortable in the winter. Mazda doesn’t offer heated seats in the third row of the CX-9.

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 CX-9 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 CX-9 doesn’t offer an automated parking system.
