The iX’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The bZ4X doesn’t offer pre-crash pretensioners.

Both the iX and bZ4X have child safety locks to prevent children from opening the rear doors. The iX 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 bZ4X’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, Full-Time Four-Wheel Drive is standard on the iX. But it costs extra on the bZ4X.

Both the iX and the bZ4X have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The BMW iX weighs 1195 to 1503 pounds more than the Toyota bZ4X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The iX comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The bZ4X’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The iX’s corrosion warranty is 7 years longer than the bZ4X’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the iX for 1 year and 11000 miles longer than Toyota pays for maintenance for the bZ4X (3/36,000 vs. 2/25000).

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Toyota vehicles. J.D. Power ranks BMW above average in initial quality. With 7 more problems per 100 vehicles, Toyota is rated lower.

Engine

The iX xDrive50’s standard electric motors produces 315 more horsepower (516 vs. 201) and 368 lbs.-ft. more torque (564 vs. 196) than the bZ4X’s standard electric motor. The iX xDrive50’s electric motors produces 302 more horsepower (516 vs. 214) and 316 lbs.-ft. more torque (564 vs. 248) than the bZ4X’s optional electric motors. The iX M60’s standard electric motors produces 396 more horsepower (610 vs. 214) and 501 lbs.-ft. more torque (749 vs. 248) than the bZ4X’s optional electric motors.

As tested in Car and Driver the iX xDrive50 is faster than the Toyota bZ4X electric motors:

	iX	bZ4X
Zero to 60 MPH	4 sec	6.3 sec
Zero to 100 MPH	9.3 sec	18.5 sec
5 to 60 MPH Rolling Start	4.3 sec	6.4 sec
Quarter Mile	12.3 sec	14.9 sec
Speed in 1/4 Mile	115 MPH	92 MPH
Top Speed	123 MPH	104 MPH

		Limited Electric Motor	242 miles
	AWD	XLE Electric Motors	228 miles
		Limited Electric Motors	222 miles

Brakes and Stopping

For better stopping power the iX’s brake rotors are larger than those on the bZ4X:

	iX	bZ4X
Front Rotors	13.7 inches	12.9 inches
Rear Rotors	13.6 inches	12.5 inches

The iX stops much shorter than the bZ4X:

	iX	bZ4X
70 to 0 MPH	158 feet	174 feet	Car and Driver

Tires and Wheels

For better traction, the iX’s optional tires are larger than the largest tires available on the bZ4X (275/40R22 vs. 235/50R20).

The iX’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 bZ4X’s 50 series tires.

For better ride, handling and brake cooling the iX has standard 20-inch wheels. Smaller 18-inch wheels are standard on the bZ4X XLE. The iX’s optional 22-inch wheels are larger than the 20-inch wheels on the bZ4X Limited.

Suspension and Handling

The iX 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 bZ4X’s suspension doesn’t offer adjustable shock absorbers.

The iX has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The iX’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The bZ4X doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the iX’s wheelbase is 5.9 inches longer than on the bZ4X (118.1 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the iX is 3 inches wider in the front and 3.8 inches wider in the rear than on the bZ4X.

The iX xDrive50 handles at .88 G’s, while the bZ4X Limited AWD pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

For greater off-road capability the iX has a greater minimum ground clearance than the bZ4X (8.8 vs. 8.1 inches), allowing the iX to travel over rougher terrain without being stopped or damaged.

Chassis

The front grille of the iX uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The bZ4X doesn’t offer active grille shutters.

Passenger Space

The iX has 2.9 inches more front headroom, 3.7 inches more front shoulder room, 2.4 inches more rear headroom, 3.6 inches more rear legroom and 2.3 inches more rear shoulder room than the bZ4X.

Cargo Capacity

The iX has a much larger cargo volume with its rear seat up than the bZ4X with its rear seat up (35.5 vs. 27.7 cubic feet). The iX has a much larger cargo volume with its rear seat folded than the bZ4X with its rear seat folded (77.9 vs. 56.9 cubic feet).

The iX’s cargo area is larger than the bZ4X’s in almost every dimension:

	iX	bZ4X
Length to seat (2nd/1st)	41”/75”	38.8”/72.6”
Max Width	43.8”	56.1”
Min Width	43.8”	38.1”
Height	31.6”	29.8”

Pressing a switch automatically lowers the iX’s rear seats, to make changing between passengers and cargo easier. The bZ4X doesn’t offer automatic folding seats.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that BMW service is better than Toyota. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 18% lower rating, Toyota is ranked 20th.

Ergonomics

When two different drivers share the iX, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position, outside mirror angle and radio stations. The bZ4X doesn’t offer a memory system.

The iX’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The bZ4X doesn’t offer an easy entry system.

The iX 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 bZ4X doesn’t offer a heads-up display.

The iX’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 bZ4X’s power window (except driver window) and power lock switches are unlit, making them difficult to find at night and operate safely.

To improve rear visibility by keeping the rear window clear, the iX has a standard rear wiper. The bZ4X doesn’t offer a rear wiper.

Laser headlights, optional on the iX, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the bZ4X’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

To help drivers avoid possible obstacles, the iX has standard cornering lights to illuminate around corners when the turn signals are activated. The bZ4X doesn’t offer cornering lights. The iX also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

When the iX 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 bZ4X’s mirror doesn’t automatically adjust for backing.

The iX’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 bZ4X has an automatic rear view mirror, but its side mirrors don’t dim.

The iX has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the bZ4X.

The iX offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the bZ4X.

The iX’s optional Automatic Parking Assistant can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The bZ4X doesn’t offer an automated parking system.
