Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Mercedes C-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Cadillac ATS Sedan doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes C-Class Sedan are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Cadillac ATS Sedan doesn’t offer height-adjustable front seat belts.

The C-Class Sedan offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The ATS Sedan only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The C-Class Sedan’s 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 ATS Sedan doesn’t offer a driver alert monitor.

Both the C-Class Sedan and the ATS Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems and blind spot warning systems.

The ATS Sedan has not been fully tested, yet.

Suspension and Handling Comparison

The C-Class Sedan has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The C-Class Sedan’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The ATS Sedan doesn’t offer a load leveling suspension.

The C-Class Sedan’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The ATS Sedan doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the C-Class Sedan’s wheelbase is 2.5 inches longer than on the ATS Sedan (111.8 inches vs. 109.3 inches).

For better handling and stability, the track (width between the wheels) on the C-Class Sedan is 3 inches wider in the front than on the ATS Sedan.

The AMG C43 Sedan 4MATIC handles at .93 G’s, while the ATS Sedan pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The C300 Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the ATS Sedan (26.3 seconds @ .7 average G’s vs. 26.7 seconds @ .66 average G’s).

Chassis Comparison

As tested by Car and Driver while at idle, the interior of the AMG C43 Sedan 4MATIC is quieter than the ATS Sedan (41 vs. 42 dB).

Passenger Space Comparison

The C-Class Sedan has .3 inches more rear headroom, 1.7 inches more rear legroom and 1.1 inches more rear shoulder room than the ATS Sedan.

Cargo Capacity Comparison

The C-Class Sedan has a much larger trunk than the ATS Sedan (12.6 vs. 10.4 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the C-Class offers cargo security. The ATS Sedan’s non-lockable folding seat defeats cargo security.

To make loading and unloading groceries and cargo easier when your hands are full, the C-Class Sedan’s trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The C-Class Sedan also offers an optional power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper. The ATS Sedan doesn’t offer a power or hands-free opening trunk.

Ergonomics Comparison

Unlike the driver-only memory system optional at extra cost in the ATS Sedan, the C-Class Sedan offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The C-Class Sedan’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the ATS Sedan.

The C-Class Sedan’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The ATS Sedan’s rear power window switches have to be held the entire time to close them fully.

If the windows are left down on the C-Class Sedan the driver can raise them all using the key in the outside lock cylinder or the keyless remote; on a hot day the driver can lower the windows. The driver of the ATS Sedan can only operate the windows from inside the vehicle, with the ignition on.

The C-Class Sedan’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The ATS Sedan’s standard manually variable intermittent wipers have to be constantly adjusted.

A power rear sunshade is optional in the C-Class Sedan to help block heat and glare for the rear passengers. The ATS Sedan doesn’t offer a rear sunshade.

Optional air conditioned seats in the C-Class Sedan keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The ATS Sedan doesn’t offer air conditioned seats.

The C-Class Sedan’s optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The ATS Sedan doesn’t offer an automated parking system.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the C-Class Sedan is less expensive to operate than the ATS Sedan because typical repairs cost much less on the C-Class Sedan than the ATS Sedan, including $212 less for an alternator, $18 less for front brake pads, $84 less for fuel injection and $84 less for a timing belt/chain.

Recommendations Comparison

The C-Class Sedan was chosen as one of Automobile Magazine’s “All Stars” in 2015. The ATS has never been an “All Star.”

The Mercedes C-Class outsold the Cadillac ATS by over three to one during the 2016 model year.
