Over 200 people are killed each year when backed over by motor vehicles. The Supra offers optional Emergency Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The C-Class Coupe doesn’t offer backup collision prevention brakes.

Both the Supra and the C-Class Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available blind spot warning systems, rear parking sensors and rear cross-path warning.


Toyota’s powertrain warranty covers the Supra 1 year and 10,000 miles longer than Mercedes covers the C-Class Coupe. 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 Coupe ends after only 4 years or 50,000 miles.

Toyota pays for scheduled maintenance on the Supra 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 Coupe.

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 Supra’s warranty.

Tires and Wheels

For better traction, the Supra has larger tires than the C-Class Coupe (F:255/35R19 & R:275/35R19 vs. F:225/45R18 & R:245/40R18).

The Supra’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the C-Class Coupe’s standard 45 series front and 40 series rear tires. The Supra’s tires are lower profile than the C-Class Coupe’s optional 40 series front tires.

For better ride, handling and brake cooling the Supra has standard 19-inch wheels. Smaller 18-inch wheels are standard on the C-Class Coupe.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the Supra is .5 inches wider in the front and 1.5 inches wider in the rear than the average track on the C-Class Coupe.

The Supra’s front to rear weight distribution is more even (50% to 50%) than the C-Class Coupe’s (53.8% to 46.2%). This gives the Supra more stable handling and braking.

The Supra 3.0 Premium handles at 1.07 G’s, while the C 300 pulls only .91 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Supra’s turning circle is .7 feet tighter than the C 300’s (36.1 feet vs. 36.8 feet). The Supra’s turning circle is 3.6 feet tighter than the AMG C 43 Coupe’s (36.1 feet vs. 39.7 feet).


The Toyota Supra may be more efficient, handle and accelerate better because it weighs about 200 to 550 pounds less than the Mercedes C-Class Coupe.

The Supra is 12 inches shorter than the AMG C 43 Coupe, making the Supra easier to handle, maneuver and park in tight spaces.
