Compare the2025 Toyota Crown SigniaVS 2024 Infiniti QX50

The Crown Signia has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The QX50 doesn’t offer a whiplash protection system.

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 QX50 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Crown Signia. But it costs extra on the QX50.

Both the Crown Signia and QX50 have Rear Cross Traffic Alert, but the Crown Signia Limited offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX50’s Rear Cross Traffic Alert 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 QX50 doesn’t offer a driver alert monitor.

Both the Crown Signia and the QX50 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, height adjustable front shoulder belts, 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.

The power windows standard on both the Crown Signia and the QX50 have locks to prevent small children from operating them.

The QX50 prevents the driver from operating the other windows just as it does the other passengers.

The Crown Signia’s standard Smart Key System 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. Infiniti Intelligent Key standard on the QX50 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

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 is only available on the QX50 Sport/Sensory/Autograph.
