For enhanced safety, the front and rear seat shoulder belts of the Mercedes CLA 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 CT4 doesn’t offer pretensioners for the rear seat belts.

The CLA’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CT4 doesn’t offer pre-crash pretensioners.

The CLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The CT4 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 CLA’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 CT4 doesn’t offer a driver alert monitor.

Both the CLA and the CT4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, blind spot warning systems and rear cross-path warning.

The CLA 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 CT4 doesn’t offer an SMG or a conventional manual transmission.

The CLA 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 CT4’s suspension doesn’t offer adjustable shock absorbers.

The CLA’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 CT4 doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the CLA is 3.2 inches wider in the front and 1.4 inches wider in the rear than on the CT4.

For better maneuverability, the CLA’s turning circle is 1 foot tighter than the CT4’s (36.1 feet vs. 37.1 feet). The CLA’s turning circle is 1.9 feet tighter than the CT4 AWD’s (36.1 feet vs. 38 feet).

The CLA uses gas struts to support the hood for easier service access. The CT4 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Unlike the driver-only memory seat and mirrors in the CT4 Premium Luxury/Sport, the CLA 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 CLA’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 CT4’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the CLA the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the CT4 can only close the windows from inside the vehicle, with the ignition on.

The CLA’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 CT4’s standard manually variable intermittent wipers have to be constantly adjusted.

The CT4 Premium Luxury/Sport’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The CLA’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The CLA’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The CT4 doesn’t offer an automated parking system.
