Both the XE and C-Class Sedan have child safety locks to prevent children from opening the rear doors. The XE 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 C-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.

The XE has a standard Whiplash Reduction System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Reduction System moves the headrests forward to prevent neck and spine injuries. The C-Class Sedan doesn’t offer a whiplash protection system.

When descending a steep, off-road slope, the XE’s standard All Surface Progress Control allows you to creep down safely. The C-Class Sedan doesn’t offer All Surface Progress Control.

To help make backing safer, the XE (except Base)’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The C-Class Sedan doesn’t offer a cross-path warning system.

Both the XE and the C-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available all-wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, around view monitors and driver alert monitors.


The XE comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The C-Class Sedan’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

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

Jaguar pays for scheduled maintenance on the XE for 5 years and 60,000 miles. Jaguar will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the C-Class Sedan.


The XE S’ 3.0 supercharged V6 produces 18 more horsepower (380 vs. 362) than the AMG C 43 Sedan’s optional 3.0 turbo V6.

The XE’s 2.0 turbo diesel produces 45 lbs.-ft. more torque (318 vs. 273) than the C 300 Sedan’s standard 2.0 turbo 4 cyl.

Tires and Wheels

For better traction, the XE S’ optional tires are larger than the largest tires available on the C-Class Sedan (F:235/35R20 & R:265/30R20 vs. F:225/40R19 & R:255/35R19).

The XE S’ optional 235/35R20 front and 265/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the C-Class Sedan’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the XE S offers optional 20-inch wheels. The C-Class Sedan’s largest wheels are only 19-inches.

The XE has a standard 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 C-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 C-Class Sedan don’t even offer run-flats.

Suspension and Handling

For better handling and stability, the average track (width between the wheels) on the XE is 1 inch wider in the front and 1.9 inches wider in the rear than the average track on the C-Class Sedan.

The XE R-Sport handles at .94 G’s, while the C 300 Sedan 4MATIC pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The XE R-Sport executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the C 300 Sedan 4MATIC (24.9 seconds @ .79 average G’s vs. 26.3 seconds @ .7 average G’s).


The design of the Jaguar XE amounts to more than styling. The XE offers aerodynamic coefficients of drag from .28 to .3 Cd (depending on bodystyle and options). That is lower than the C-Class Sedan (.3 to .32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the XE get better fuel mileage.

As tested by Car and Driver, the interior of the XE R-Sport AWD is quieter than the AMG C 43 Sedan:

Cargo Capacity

The XE has a much larger trunk than the C-Class Sedan (14.7 vs. 12.6 cubic feet).


Heated windshield washer nozzles are optional on the XE to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The C-Class Sedan doesn’t offer heated windshield washer nozzles.

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