Both the Mulsanne and LS Series have child safety locks to prevent children from opening the rear doors. The Mulsanne 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 LS Series’ 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.

Both the Mulsanne and the LS Series have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems and rearview cameras.

The Bentley Mulsanne weighs 884 to 1357 pounds more than the Lexus LS Series. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

For better traction, the Mulsanne has larger tires than the LS Series (265/45R20 vs. 245/50R19). The Mulsanne’s tires are larger than the largest tires available on the LS Series (265/45R20 vs. 245/45R20).

The Mulsanne’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the LS Series’ standard 50 series tires. The Mulsanne’s optional tires have a lower 40 series profile than the LS Series F Sport’s 45 series front tires.

For better ride, handling and brake cooling the Mulsanne has standard 20-inch wheels. Smaller 19-inch wheels are standard on the LS Series. The Mulsanne’s optional 21-inch wheels are larger than the 20-inch wheels optional on the LS Series.

The Mulsanne 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 LS Series; 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.

The front and rear suspension of the Mulsanne uses air springs for a smoother, controlled ride than the LS Series, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
