Safety

The A-Class offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Cadenza doesn’t offer all-wheel drive.

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 Cadenza doesn’t offer a driver alert monitor.

Both the A-Class and the Cadenza have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available lane departure warning systems, blind spot warning systems and around view monitors.

Warranty

The A-Class’ 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Cadenza runs out after 100,000 miles.

Fuel Economy and Range

On the EPA test cycle the A-Class gets better fuel mileage than the Cadenza:

In heavy traffic or at stoplights the A-Class’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Cadenza doesn’t offer an automatic engine start/stop system.

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 Cadenza doesn’t offer an SMG or a conventional manual transmission.

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the A-Class can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Cadenza doesn’t offer run-flat tires.

Suspension and Handling

The A-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 Cadenza’s suspension doesn’t offer adjustable shock absorbers.

The A-Class’ 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 Cadenza doesn’t offer drift compensation steering.

For better maneuverability, the A-Class’ turning circle is 1.1 feet tighter than the Cadenza’s (36.1 feet vs. 37.2 feet).

Chassis

The Mercedes A-Class may be more efficient, handle and accelerate better because it weighs about 350 to 400 pounds less than the Kia Cadenza.

The A-Class is 1 foot, 4.6 inches shorter than the Cadenza, 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 Cadenza doesn’t offer folding rear seats, only a ski pass-through.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Kia. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 42% lower rating, Kia is ranked 18th.

Ergonomics

The A-Class has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cadenza doesn’t offer a remote starting system.

Unlike the driver-only memory system in the Cadenza Technology/Limited, 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’ 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 Cadenza’s standard manually variable intermittent wipers have to be constantly adjusted.

To help drivers avoid possible obstacles, the A-Class offers optional cornering lights to illuminate around corners when the turn signals are activated. The Cadenza doesn’t offer cornering lights. The A-Class also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The A-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 Cadenza has an automatic rear view mirror, but its side mirrors don’t dim.

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 Cadenza doesn’t offer an automated parking system.
