For enhanced safety, the front and rear seat shoulder belts of the BMW X3 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 Toyota 4Runner doesn’t offer pretensioners for its second-row seat belts.

The X3 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 4Runner doesn’t offer front seat center airbags.

Over 200 people are killed each year when backed over by motor vehicles. The X3 offers an optional Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 4Runner doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X3. But it costs extra on the 4Runner.

For better protection of the passenger compartment, the X3 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 X3 and the 4Runner have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

Warranty

The X3 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 or 14,000 miles sooner.

The X3’s corrosion warranty is 7 years longer than the 4Runner’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X3 for 1 year and 11000 miles longer than Toyota pays for maintenance for the 4Runner (3/36,000 vs. 2/25000).

Engine

The X3 30 xDrive’s standard 2.0 turbo 4-cylinder hybrid produces 17 lbs.-ft. more torque (295 vs. 278) than the 4Runner’s 4.0 DOHC V6. The X3 M50 xDrive’s standard 3.0 turbo 6-cylinder hybrid produces 123 more horsepower (393 vs. 270) and 150 lbs.-ft. more torque (428 vs. 278) than the 4Runner’s 4.0 DOHC V6.

Fuel Economy and Range

On the EPA test cycle the X3 gets better mileage than the 4Runner:

			MPG
X3
	AWD	2.0 turbo 4-cyl. Hybrid	27 city/33 hwy
		3.0 turbo 6-cyl. Hybrid	25 city/30 hwy
4Runner
	RWD	4.0 DOHC V6	16 city/19 hwy
	AWD	4.0 DOHC V6	16 city/19 hwy

Regenerative brakes improve the X3’s fuel efficiency by converting inertia back into energy instead of wasting it. The 4Runner doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the X3’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The 4Runner doesn’t offer an automatic engine start/stop system.

The X3 has a standard locking fuel door with a power remote release convenient to the driver. The fuel filler door is not lockable on the 4Runner. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X3 higher (6 to 7 out of 10) than the Toyota 4Runner (5). This means the X3 produces up to 8 pounds less smog-producing pollutants than the 4Runner every 15,000 miles.

Transmission

An eight-speed automatic is standard on the BMW X3, for better acceleration and lower engine speed on the highway. Only a five-speed automatic is available for the 4Runner.

The X3 M50’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The 4Runner doesn’t offer launch control.

Brakes and Stopping

For better stopping power the X3 M50 xDrive’s brake rotors are larger than those on the 4Runner:

	X3 M50 xDrive	4Runner
Front Rotors	13.7 inches	13.3 inches
Rear Rotors	13.5 inches	12.3 inches

Tires and Wheels

The X3’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the 4Runner’s standard 70 series tires. The X3’s optional 255/40R21 front and 285/35R21 rear tires have a lower 40 series front and 35 series rear profile than the 4Runner Limited/TRD Sport’s 60 series tires.

For better ride, handling and brake cooling the X3 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the 4Runner. The X3’s optional 21-inch wheels are larger than the 20-inch wheels on the 4Runner Limited/TRD Sport.

Suspension and Handling

For superior ride and handling, the BMW X3 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 X3 offers an optional 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.

For a smoother ride and more stable handling, the X3’s wheelbase is 3 inches longer than on the 4Runner (112.8 inches vs. 109.8 inches).

The X3’s front to rear weight distribution is more even (50.5% to 49.5%) than the 4Runner’s (53.6% to 46.4%). This gives the X3 more stable handling and braking.

Chassis

The BMW X3 may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Toyota 4Runner.

The X3 is 3 inches shorter than the 4Runner, making the X3 easier to handle, maneuver and park in tight spaces. The X3 is 4.1 inches shorter than the 4Runner TRD Off-Road/Pro.

Unibody construction lowers the X3’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The 4Runner doesn’t use unibody construction, but a body-on-frame design.

Passenger Space

The X3 has 1.2 inches more front headroom, .1 inches more front shoulder room and 3.4 inches more rear legroom than the 4Runner.

Cargo Capacity

The X3 has a much larger cargo volume than the 4Runner with its rear seat up (31.5 vs. 9 cubic feet).

Pulling a handle automatically lowers the X3’s rear seats, to make changing between passengers and cargo easier. The 4Runner doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier when your hands are full, the X3’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The 4Runner doesn’t offer a power or hands-free opening liftgate.

Servicing Ease

A Condition-Based Service Display is standard on the X3 to save the owner time and money by calculating maintenance intervals for oil changes, transmission fluid replacement, and vehicle inspections, based on actual driving conditions. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Toyota doesn’t offer a maintenance reminder on the 4Runner.

Ergonomics

The engine computer on the X3 automatically engages the starter until the car starts with one twist of the key and disables the starter while the engine is running. The 4Runner’s starter can be accidentally engaged while the engine is running, making a grinding noise and possibly damaging the starter and ring gear.

The X3 offers an optional heads-up display that projects speed, warning 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 4Runner doesn’t offer a heads-up display.

The X3’s power parking brake sets with one touch and releases with one touch or automatically. The 4Runner’s parking brake has to be released manually.

The power windows standard on both the X3 and the 4Runner have locks to prevent small children from operating them. When the lock on the X3 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 X3’s standard Comfort Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Smart Key System standard on the 4Runner doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The X3’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 4Runner’s power mirror and cruise control switches are unlit, making them difficult to find at night and operate safely.

The X3’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 X3 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.

The X3 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/TRD Pro.

To help drivers avoid possible obstacles, the X3 offers optional cornering lights to illuminate around corners when the turn signals are activated. The 4Runner doesn’t offer cornering lights. The X3 also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

Manual rear side window sunshades are available in the X3 to help block heat and glare for the rear passengers. The 4Runner doesn’t offer rear side window sunshades.

The X3’s power mirror controls are mounted on the armrest for easy access. The 4Runner’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

When the X3 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 X3’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to 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.

Both the BMW X3 and Toyota 4Runner offer exterior mirrors that can be folded to provide convenience. The X3 features standard power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the 4Runner’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The X3 has standard heated front seats. Heated front seats are only available on the 4Runner Premium/Limited/TRD Pro. The X3 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the 4Runner.

The BMW X3 has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Homelink® is only available on the 4Runner Premium/Limited/TRD Pro.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X3 has a standard wireless phone charging system (Qi) in the front center console. The 4Runner doesn’t offer wireless personal charging.

The X3’s Parking Assistant can parallel park by itself, with the driver only controlling the transmission and speed with the brake pedal. With its available fully controlled system, the driver just activates it and it parks autonomously, starting, stopping and changing direction automatically. Optional Remote Control Parking will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The 4Runner doesn’t offer an automated parking system.
