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 E-Class Sedan are reminded to check the back seat if they opened the rear door before starting out. The LS doesn’t offer a back seat reminder.
The E-Class Sedan has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The LS doesn’t offer front seat center airbags.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Mercedes E-Class Sedan achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Lexus LS has not been tested.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The E-Class Sedan has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The LS doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the E-Class Sedan and the LS have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and lane departure warning systems.
