Safety

For enhanced safety, the front shoulder belts of the Cadillac XTS are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Mercedes E-Class Sedan has only front height-adjustable seat belts.

Both the XTS and E-Class Sedan have child safety locks to prevent children from opening the rear doors. The XTS has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The E-Class Sedan’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Over 200 people are killed each year when backed over by motor vehicles. The XTS offers optional Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The E-Class Sedan doesn’t offer backup collision prevention brakes.

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

Warranty

Cadillac’s powertrain warranty covers the XTS 2 years and 20,000 miles longer than Mercedes covers the E-Class Sedan. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the E-Class Sedan ends after only 4 years or 50,000 miles.

The XTS’ corrosion warranty is 1 year longer than the E-Class Sedan’s (6 vs. 5 years).

Cadillac pays for the first scheduled maintenance on the XTS. Cadillac will pay for an oil change, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the E-Class Sedan.

There are over 2 times as many Cadillac dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the XTS’ warranty.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the XTS’ reliability 36 points higher than the E-Class Sedan.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Cadillac 12th in initial quality, above the industry average. With 2 more problems per 100 vehicles, Mercedes is ranked 14th.

Fuel Economy and Range

The XTS FWD’s standard fuel tank has 1.6 gallons more fuel capacity than the E-Class Sedan 300’s standard fuel tank (19 vs. 17.4 gallons), for longer range between fill-ups.

The XTS has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The E-Class Sedan doesn’t offer a cap-less fueling system.

Brakes and Stopping

The XTS stops shorter than the E-Class Sedan:

Consumer Reports

Tires and Wheels

For better ride, handling and brake cooling the XTS has standard 19-inch wheels. Smaller 18-inch wheels are standard on the E-Class Sedan. The XTS’ optional 20-inch wheels are larger than the 19-inch wheels optional on the E-Class Sedan.

The XTS offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the E-Class Sedan; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some models of the E-Class Sedan don’t even offer run-flats.

Suspension and Handling

The rear suspension of the XTS uses air springs for a smoother, controlled ride than the E-Class Sedan, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

Chassis

The XTS uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The E-Class Sedan doesn’t offer active noise cancellation.

As tested by Car and Driver while under full throttle, the interior of the XTS is quieter than the E 300 Sedan 4MATIC (74 vs. 76 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the XTS a Large car, while the E-Class Sedan is rated a Mid-size.

The XTS has 6.2 cubic feet more passenger volume than the E-Class Sedan (104.2 vs. 98).

The XTS has 1.6 inches more front headroom, .4 inches more front legroom, .1 inches more front shoulder room and 3.8 inches more rear legroom than the E-Class Sedan.

Cargo Capacity

The XTS has a much larger trunk than the E-Class Sedan (18 vs. 13.1 cubic feet).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Mercedes. J.D. Power ranks Cadillac third in service department satisfaction. With a 3% lower rating, Mercedes is ranked 6th.

Ergonomics

The XTS’ instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The E-Class Sedan does not have an oil pressure gauge.

Consumer Reports rated the XTS’ headlight performance “Good,” a higher rating than the E-Class Sedan’s headlights, which were rated “Poor.”

Both the XTS and the E-Class Sedan offer optional heated front seats. The XTS also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the E-Class Sedan.

Economic Advantages

Insurance will cost less for the XTS owner. The Complete Car Cost Guide estimates that insurance for the XTS will cost $485 to $4720 less than the E-Class Sedan over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Cadillac XTS will be $3897 to $6505 less than for the Mercedes E-Class Sedan.
