Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Mercedes C Class have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Cadillac CTS doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front and rear seat shoulder belts of the Mercedes C Class 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 CTS has only front height-adjustable seat belts.

The C Class has standard whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the whiplash protection system moves the headrests forward to prevent neck and spine injuries. The CTS doesn’t offer a whiplash protection system.

Both the C Class and the CTS have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, height adjustable front shoulder belts, plastic fuel tanks, four wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Consumer Reports

Tires and Wheels Comparison

The C Class’ standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the CTS’ standard 55 series tires. The C Class Sport’s optional 225/40R18 front and 255/35R18 rear tires have a lower 40 series front and 35 series rear profile than the CTS 3.6 V6’s optional 45 series tires.

Suspension and Handling Comparison

The C Class offers an optional 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 CTS’ suspension doesn’t offer adjustable shock absorbers.

The C350 goes through Road & Track’s slalom faster than the CTS Sedan (63.8 vs. 63.7 MPH).

Chassis Comparison

The Mercedes C Class may be more efficient, handle and accelerate better because it weighs about 350 to 500 pounds less than the Cadillac CTS.

Cargo Capacity Comparison

A low lift-over trunk design makes loading and unloading the C Class easier. The C Class’ trunk lift-over height is 26.4 inches, while the CTS’ liftover is 28.3 inches.

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

Ergonomics Comparison

The C Class’ 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 CTS’ 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 the driver can raise them all using the keyless remote (remote must be aimed at door sensor); on a hot day the driver can lower the windows. The driver of the CTS can only operate the windows from inside the vehicle, with the ignition on.

The C Class has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The CTS doesn’t offer a locking fuel door.

A power rear sun shade is optional in the C Class to help block heat and glare for the rear passengers. The CTS doesn’t offer a rear sun shade.

The C Class offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The CTS has an automatic rear view mirror, but its side mirrors don’t dim.
