Compare the2025 Toyota Crown SigniaVS 2025 BMW X3

For enhanced safety, the front seat shoulder belts of the Toyota Crown Signia are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X3 doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Crown Signia are reminded to check the back seat if they opened the rear door before starting out. The X3 doesn’t offer a back seat reminder.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Toyota Crown Signia achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The BMW X3 has not been tested.

The Crown Signia has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The X3 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.

The Toyota Crown Signia offers an optional Bird’s Eye View Camera and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the BMW X3 doesn’t offer a camera washer, requiring manual cleaning.

Both the Crown Signia and X3 have rear cross-traffic warning, but the Crown Signia Limited offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The X3’s Cross Traffic Warning doesn’t automatically brake.

The Crown Signia’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 X3 doesn’t offer a driver alert monitor.

Both the Crown Signia and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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 and available around view monitors.

Toyota’s powertrain warranty covers the Crown Signia 1 year and 10,000 miles longer than BMW covers the X3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the X3 ends after only 4 years or 50,000 miles.

There are almost 4 times as many Toyota dealers as there are BMW dealers, which makes it much easier should you ever need service under the Crown Signia’s warranty.

The battery on the Crown Signia is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Crown Signia’s battery 20 to 30 degrees cooler, its life is increased by years. The X3’s battery is in the hot engine compartment.

On the EPA test cycle the Crown Signia gets better mileage than the X3:

To lower fuel costs and make buying fuel easier, the Toyota Crown Signia uses regular unleaded gasoline. The X3 M50 xDrive requires premium, which can cost on average about 84.9 cents more per gallon.

The Crown Signia has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The X3 doesn’t offer a CVT.

The Crown Signia has 1.9 inches more front legroom, .7 inches more rear headroom and .8 inches more rear legroom than the X3.

The Crown Signia has a larger cargo volume with its rear seat folded than the X3 with its rear seat folded (68.8 vs. 67.1 cubic feet).

The Crown Signia’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The X3 doesn’t offer an easy entry system.

To improve rear visibility by keeping the rear window clear, the Crown Signia has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the X3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Crown Signia 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 X3.

The Crown Signia 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 costs extra on the X3.
