Safety

The A-Class’ 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 A-Class and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty

There are over 79 percent more Mercedes dealers than there are Infiniti dealers, which makes it much easier should you ever need service under the A-Class’ warranty.

Transmission

The A-Class offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Q50 doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

The A-Class stops much shorter than the Q50:

Car and Driver

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A-Class is 1.2 inches wider in the front than the average track on the Q50.

The A 220 4MATIC handles at .95 G’s, while the Q50 Red Sport 400 pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the A-Class’ turning circle is .6 feet tighter than the Q50’s (36.1 feet vs. 36.7 feet). The A-Class’ turning circle is 1.3 feet tighter than the Q50 AWD’s (36.1 feet vs. 37.4 feet).

Chassis

The Mercedes A-Class may be more efficient, handle and accelerate better because it weighs about 400 to 600 pounds less than the Infiniti Q50.

The A-Class is 10.5 inches shorter than the Q50, making the A-Class easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The A-Class’ standard rear seats fold to accommodate long and bulky cargo. The Q50 Pure doesn’t offer folding rear seats.

To make loading groceries and cargo easier when your hands are full, the A-Class’ available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Q50 doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the Q50 (except Pure/Luxe), the A-Class has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The A-Class offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Q50 doesn’t offer a heads-up display.

Optional air-conditioned seats in the A-Class keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Q50 doesn’t offer air-conditioned seats.

The A-Class’ 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 Q50 doesn’t offer an automated parking system.
