Compare the2024 BMW X4VS 2024 Land Rover Defender

The X4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Defender doesn’t offer pre-crash pretensioners.

The BMW X4 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Defender doesn’t offer knee airbags.

The X4 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Defender doesn’t offer a whiplash protection system.

The X4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Defender doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The X4 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 Defender doesn’t offer automatic braking for stationary objects directly to the rear.

Both the X4 and the Defender have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, 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, driver alert monitors and available around view monitors.

The X4’s corrosion warranty is 6 years longer than the Defender’s (12 vs. 6 years).

BMW pays for scheduled maintenance on the X4 for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Land Rover doesn’t pay scheduled maintenance for the Defender.

There are over 72 percent more BMW dealers than there are Land Rover dealers, which makes it much easier should you ever need service under the X4’s warranty.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the X4’s reliability 20 points higher than the Defender.

J.D. Power and Associates rated the X4 second among compact premium suvs in their 2023 Initial Quality Study. The Defender isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Land Rover vehicles. With 11 fewer problems per 100 vehicles, JD Power ranks BMW higher than Land Rover.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Land Rover vehicles. J.D. Power ranks BMW above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Land Rover is rated below average.

On the EPA test cycle the X4 gets better mileage than the Defender 110/130:

Regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. The Defender doesn’t offer a regenerative braking system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X4 higher (5 to 7 out of 10) than the Land Rover Defender (3 to 7). This means the X4 produces up to 24.5 pounds less smog-producing pollutants than the Defender every 15,000 miles.

The EPA certifies the BMW X4 at emission levels ranging from “Low Emissions Vehicle” (LEV) to “Super Ultra Low Emissions Vehicle” (SULEV). The Land Rover Defender is only certified to “Low Emissions Vehicle” (LEV) standards.

The X4 stops much shorter than the Defender:

The X4’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 Defender’s standard 70 series tires. The X4’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Defender’s optional 45 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Defender.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Defender doesn’t offer run-flat tires.

The X4 M40i handles at .89 G’s, while the Defender 110 SE pulls only .67 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 4.5 seconds quicker than the Defender 110 SE (25.6 seconds @ .73 average G’s vs. 30.1 seconds @ .54 average G’s).

The BMW X4 may be more efficient, handle and accelerate better because it weighs about 400 to 1400 pounds less than the Land Rover Defender.

The X4 is 9.9 inches shorter than the Defender 110, making the X4 easier to handle, maneuver and park in tight spaces.

The X4 is 13.6 inches shorter in height than the Defender, making the X4 much easier to wash and garage and drive (lower center of gravity).

For excellent aerodynamics, the X4 has standard flush composite headlights. The Defender has recessed headlights that spoil its aerodynamic shape and create extra drag.

The front grille of the X4 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Defender doesn’t offer active grille shutters.

The X4 has a much larger cargo volume than the Defender 110 with its rear seat up (18.5 vs. 10.7 cubic feet).

Pulling a handle automatically lowers the X4’s rear seats, to make changing between passengers and cargo easier. The Defender doesn’t offer automatic folding seats.

The X4’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The Defender’s swing out door blocks loading from the driver’s side.

To make loading and unloading groceries and cargo easier, especially for short adults, the X4 has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Defender doesn’t offer a power cargo door.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Land Rover. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 51% lower rating, Land Rover is ranked 30th.

If the windows are left open on the X4 the driver can close them all at the outside door handle or from a distance using the remote.

The driver of the Defender can only operate the windows from inside the vehicle, with the ignition on.

To help drivers avoid possible obstacles, the X4 has standard cornering lights to illuminate around corners when the turn signals are activated. The Defender doesn’t offer cornering lights. The X4 also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the X4 has standard extendable sun visors. The Defender doesn’t offer extendable visors.

The X4’s sun-visors swivel front-to-side to block glare from the side windows. The Defender’s visors are fixed into the windshield header.

The X4’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Defender doesn’t offer an automated parking system.

J.D. Power and Associates rated the X4 first among compact premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Defender was rated second in its category.
