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 and force limiters to limit the pressure the belts will exert on the passengers. The Infiniti Q50 doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front and rear 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 Infiniti Q50 has only front height-adjustable seat belts.

The C-Class Sedan has standard NECK-PRO Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Q50 doesn’t offer a whiplash protection system.

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 Q50 doesn’t offer a driver alert monitor.

Both the C-Class Sedan and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height-adjustable front shoulder belts, traction control and electronic stability systems to prevent skidding.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mercedes C-Class Sedan is safer than the Infiniti Q50:

Warranty Comparison

There are almost 2 times as many Mercedes dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the C-Class Sedan’s warranty.

Reliability Comparison

J.D. Power and Associates’ 2013 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Infiniti vehicles.

Tires and Wheels Comparison

The C-Class Sedan Luxury’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Q50’s standard 55 series tires. The C-Class Sedan’s optional 255/35R18 rear tires have a lower 35 series profile than the Q50’s 40 series tires.

Suspension and Handling Comparison

The C-Class Sedan has standard front and rear gas-charged shocks for better control over choppy roads. The Q50’s suspension doesn’t offer gas-charged shocks.

The C-Class Sedan has a standard continuously variable suspension system. Using sensors on steering angle, speed and other driver inputs, the shocks soften to improve ride, or stiffen when appropriate to aid handling on tricky roads. The Q50’s suspension doesn’t offer adjustable shock absorbers.

The C250 Sedan handles at .91 G’s, while the Q50S pulls only .86 G’s of cornering force in a Road & Track skidpad test.

For better maneuverability, the C-Class Sedan’s turning circle is 1.4 feet tighter than the Q50’s (35.3 feet vs. 36.7 feet). The C-Class Sedan’s turning circle is 2.1 feet tighter than the Q50 AWD’s (35.3 feet vs. 37.4 feet).

Chassis Comparison

The C-Class Sedan is 7.5 inches shorter than the Q50, making the C-Class Sedan easier to handle, maneuver and park in tight spaces.

Ergonomics Comparison

Unlike the driver-only memory system optional in the Q50, the C-Class Sedan offers an optional driver and 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 power windows standard on both the C-Class Sedan and the Q50 have locks to prevent small children from operating them. When the lock on the C-Class Sedan is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q50 prevents the driver from operating the other windows just as it does the other passengers.

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 Q50’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The C-Class Sedan offers available headlight washers to keep headlight output high. The Q50 doesn’t offer headlight washers.

A power rear sunshade is optional in the C-Class Sedan to help block heat and glare for the rear passengers. The Q50 doesn’t offer a rear sunshade.

Recommendations Comparison

Consumer Reports® chose the Mercedes C-Class Sedan as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.

The Mercedes C-Class outsold the Infiniti Q50 by almost five to one during 2013.
