Safety Comparison

The X5 offers optional City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The 4Runner doesn't offer collision warning or crash mitigation brakes.

A passive infrared night vision system optional on the X5 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The 4Runner doesn’t offer a night vision system.

The X5’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The 4Runner doesn’t offer a lane departure warning system.

The X5 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The 4Runner only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The X5’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The 4Runner doesn’t offer a system to reveal objects in the driver’s blind spots.

The X5’s optional 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 4Runner doesn’t offer a driver alert monitor.

For better protection of the passenger compartment, the X5 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The 4Runner uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the X5 and the 4Runner have standard driver and passenger frontal airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Warranty Comparison

The X5 comes with a full 4 year/50,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The 4Runner’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

The X5’s corrosion warranty is 7 years longer than the 4Runner’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X5 for 2 years and 25000 miles longer than Toyota pays for maintenance for the 4Runner (4/50,000 vs. 2/25000).

Reliability Comparison

The battery on the X5 is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the X5’s battery 20 to 30 degrees cooler, its life is increased by years. The 4Runner’s battery is in the hot engine compartment.

Engine Comparison

The X5 s/xDrive35i’s standard 3.0 turbo 6 cyl. produces 30 more horsepower (300 vs. 270) and 22 lbs.-ft. more torque (300 vs. 278) than the 4Runner’s 4.0 DOHC V6. The X5 xDrive50i’s standard 4.4 turbo V8 produces 175 more horsepower (445 vs. 270) and 202 lbs.-ft. more torque (480 vs. 278) than the 4Runner’s 4.0 DOHC V6.

The X5’s 3.0 turbo diesel produces 135 lbs.-ft. more torque (413 vs. 278) than the 4Runner’s 4.0 DOHC V6.

Consumer Reports

Tires and Wheels Comparison

For better traction, the X5 has larger standard tires than the 4Runner (255/55R18 vs. 245/60R20). The X5’s optional tires are larger than the largest tires available on the 4Runner (F:275/40R20 & R:315/35R20 vs. 265/70R17).

The X5’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the 4Runner SR5/Trail’s standard 70 series tires. The X5’s optional 275/40R20 front and 315/35R20 rear tires have a lower 40 series front and 35 series rear profile than the 4Runner Limited’s 60 series tires.

For better ride, handling and brake cooling the X5 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 4Runner SR5/Trail.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X5 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The 4Runner doesn’t offer run-flat tires.

Suspension and Handling Comparison

For superior ride and handling, the BMW X5 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Toyota 4Runner has a solid rear axle, with a non-independent rear suspension.

The X5 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Toyota doesn’t offer an active suspension on the 4Runner.

The X5 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 4Runner’s suspension doesn’t offer adjustable shock absorbers.

The X5 has a standard automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The 4Runner doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X5’s wheelbase is 5.7 inches longer than on the 4Runner (115.5 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the X5 is 1.5 inches wider in the front and 1.8 inches wider in the rear than on the 4Runner.

The X5’s front to rear weight distribution is more even (49.5% to 50.5%) than the 4Runner’s (53.6% to 46.4%). This gives the X5 more stable handling and braking.

The X5 xDrive35d handles at .82 G’s, while the 4Runner Trail 4x4 pulls only .73 G’s of cornering force in a Motor Trend skidpad test.

The X5 xDrive50i executes Motor Trend’s “Figure Eight” maneuver 3.2 seconds quicker than the 4Runner Trail 4x4 (26.3 seconds @ .72 average G’s vs. 29.5 seconds @ .55 average G’s).

Chassis Comparison

Unibody construction makes the X5’s chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The 4Runner doesn’t use unibody construction, but a body-on-frame design.

The design of the BMW X5 amounts to more than styling. The X5 has an aerodynamic coefficient of drag of .33 Cd. That is lower than the 4Runner (.36) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the X5 get better fuel mileage.

Passenger Space Comparison

The X5 has 1.2 inches more front headroom, 2.7 inches more front shoulder room, .2 inches more rear headroom, 3.7 inches more rear legroom and .5 inches more rear shoulder room than the 4Runner.

Cargo Capacity Comparison

To make loading and unloading groceries and cargo easier, especially for short adults or children, the X5 has a standard power cargo door, which opens and closes automatically by pressing a button. The 4Runner doesn’t offer a power cargo door.

Ergonomics Comparison

The X5’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The 4Runner doesn’t offer an easy entry system.

The X5 offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The 4Runner doesn’t offer a heads-up display.

The power windows standard on both the X5 and the 4Runner have locks to prevent small children from operating them. When the lock on the X5 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The 4Runner prevents the driver from operating the other windows just as it does the other passengers.

The X5 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 4Runner doesn’t offer a locking fuel door.

The X5’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 4Runner’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the X5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 4Runner doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the X5 has a standard rear variable intermittent wiper with a full on position. The rear wiper standard on the 4Runner only has an intermittent setting, so in a hard rain visibility isn’t as good.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The X5 offers available headlight washers to keep headlight output high. The 4Runner doesn’t offer headlight washers.

The X5 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 4Runner has an automatic headlight on/off feature standard only on the Limited.

While driving with high beams on, sensitive light sensors available for the X5 detect other vehicles which could be blinded and automatically switch to low beams. The 4Runner doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the X5 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The 4Runner doesn’t offer cornering lights.

When the X5 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The 4Runner’s mirror doesn’t automatically adjust for backing.

The X5 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 4Runner offers an automatic rear view mirror, but its side mirrors don’t dim.

The X5 has standard heated front seats. Heated front seats are only available on the 4Runner Trail/Limited. The X5 also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the 4Runner.

On extremely cold Winter days, the X5’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The 4Runner doesn’t offer a heated steering wheel.

The X5 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the 4Runner Limited.

To keep a safe, consistent following distance, the X5 offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The 4Runner doesn’t offer an adaptive cruise control.

The X5’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The 4Runner doesn’t offer an automated parking system.
