For enhanced safety, the front and rear seat shoulder belts of the Mercedes E-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 Cadillac CTS doesn’t offer pretensioners for the rear seat belts.

The rear seatbelts optional on the E-Class Sedan inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The CTS doesn’t offer inflatable seatbelts.

The E-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 CTS doesn’t offer a driver alert monitor.

Both the E-Class Sedan and the CTS have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems, around view monitors and rear cross-path warning.

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

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Mercedes E-Class Sedan is safer than the CTS:

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the E-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The CTS was not even a standard “Top Pick” for 2016.

To reliably start during all conditions and help handle large electrical loads, the E-Class Sedan has a standard 850-amp battery. The CTS’ 730-amp battery isn’t as powerful.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Cadillac vehicles. J.D. Power ranks Mercedes 12th in initial quality. With 6 more problems per 100 vehicles, Cadillac is ranked 17th.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Cadillac vehicles. J.D. Power ranks Mercedes 13th in reliability, above the industry average. With 32 more problems per 100 vehicles, Cadillac is ranked 23rd.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Mercedes vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Mercedes 11 places higher in reliability than Cadillac.

Regenerative brakes improve the E-Class Sedan 53 AMG’s fuel efficiency by converting inertia back into energy instead of wasting it. The CTS doesn’t offer a regenerative braking system.

Regardless of its engine, the E-Class Sedan’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The CTS V-Sport doesn’t offer an automatic engine start/stop system.

The E-Class Sedan 450/AMG 53’s standard fuel tank has 2.1 gallons more fuel capacity than the CTS (21.1 vs. 19 gallons).

The E-Class Sedan has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The E-Class Sedan’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The CTS doesn’t offer a load leveling suspension.

The E-Class Sedan’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 CTS doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the E-Class Sedan’s wheelbase is 1.1 inches longer than on the CTS (115.7 inches vs. 114.6 inches).

For better handling and stability, the average track (width between the wheels) on the E-Class Sedan is 1.8 inches wider in the front and 1 inch wider in the rear than the average track on the CTS.

The E-Class Sedan 4MATIC handles at .93 G’s, while the CTS Luxury AWD pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The E-Class Sedan 4MATIC executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the CTS Luxury AWD (25.1 seconds @ .77 average G’s vs. 26.8 seconds @ .65 average G’s).

A low lift-over trunk design makes loading and unloading the E-Class Sedan easier. The E-Class Sedan’s trunk lift-over height is 27.7 inches, while the CTS’ liftover is 29.5 inches.

To make loading and unloading groceries and cargo easier when your hands are full, the E-Class Sedan’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The CTS doesn’t offer a power or hands-free opening trunk.

Unlike the driver-only memory system in the CTS, the E-Class Sedan has standard 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.

If the windows are left open on the E-Class Sedan the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the CTS can only close the windows from inside the vehicle, with the ignition on.

The E-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 CTS’ standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer fluid is standard on the E-Class Sedan to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The CTS doesn’t offer heated windshield washer fluid.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The E-Class Sedan’s headlights were rated “Good” to “Acceptable” by the IIHS, while the CTS’ headlights are rated “Poor.”
