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 Avalon are reminded to check the back seat if they opened the rear door before starting out. The C-Class Sedan doesn't offer a back seat reminder.

The Avalon has standard Whiplash Injury Lessening Seats (WIL), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WIL system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The C-Class Sedan doesn't offer a whiplash protection system.

The Avalon 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 C-Class Sedan 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.

Over 200 people are killed each year when backed over by motor vehicles. The Avalon Limited/Touring offers optional Rear Cross-Traffic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The C-Class Sedan doesn't offer backup collision prevention brakes.

The Avalon's standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the C-Class Sedan.

To help make backing out of a parking space safer, the Avalon has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the C-Class Sedan.

Both the Avalon and the C-Class Sedan have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras and available around view monitors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Toyota Avalon is safer than the Mercedes C-Class Sedan:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Toyota Avalon is safer than the Mercedes C-Class Sedan:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Toyota's powertrain warranty covers the Avalon 1 year and 10,000 miles longer than Mercedes covers the C-Class Sedan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the C-Class Sedan ends after only 4 years or 50,000 miles.

Toyota pays for scheduled maintenance on the Avalon for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn't pay scheduled maintenance for the C-Class Sedan.

There are over 3 times as many Toyota dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Avalon's warranty.

For better traction, the Avalon Limited's tires are larger than the largest tires available on the C-Class Sedan (235/45R18 vs. 225/40R19).

The Avalon has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn't available on the C-Class Sedan; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the C-Class Sedan don't have a run-flat feature, either.

The Avalon offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The C-Class Sedan's suspension doesn't offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Avalon's wheelbase is 1.2 inches longer than on the C-Class Sedan (113 inches vs. 111.8 inches).

The design of the Toyota Avalon amounts to more than styling. The Avalon has an aerodynamic coefficient of drag of .27 Cd. That is lower than the C-Class Sedan (.3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Avalon get better fuel mileage.

The Avalon Touring uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The C-Class Sedan doesn't offer active noise cancellation.

Because it has more passenger and cargo room, the EPA rates the Avalon a Mid-size car, while the C-Class Sedan is rated a Compact.
