Over 200 people are killed each year when backed over by motor vehicles. The ES Series offers optional Intuitive Parking Assist with Auto Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A4 doesn’t offer backup collision prevention brakes.
The ES Series’ 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 A4 doesn’t offer a driver alert monitor.
Both the ES Series and the A4 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, post-collision automatic braking systems, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lexus ES Series is safer than the Audi A4:

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the ES Series its highest rating: “Top Pick Plus” for 2021, a rating granted to only 35 vehicles tested by the IIHS. The A4 has not been fully tested, yet.
