Compare the2025 Lexus ESVS 2024 Infiniti Q50

For enhanced safety, the front and rear seat shoulder belts of the Lexus ES 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 Infiniti Q50 doesn’t offer pretensioners for its rear 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 ES are reminded to check the back seat if they opened the rear door before starting out. The Q50 doesn’t offer a back seat reminder.

The Lexus ES 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 Q50 doesn’t offer knee airbags.

With its standard Pre-Collision System with Pedestrian Detection, the Lexus ES is better at preventing collisions with pedestrians than the Infiniti Q50, according to the Insurance Institute for Highway Safety:

The ES 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 Q50 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 ES’ 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 Q50 doesn’t offer a driver alert monitor.

Both the ES and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 ES has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced.

The Q50 prevents the driver from operating the other windows just as it does the other passengers.

The ES’ standard Smart Access allow you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse.
