For enhanced safety, the front and rear seat shoulder belts of the Bentley Continental GT 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 Porsche 911 doesn’t offer pretensioners for the rear seat belts.

The Continental GT’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 911 doesn’t offer pre-crash pretensioners.

The Continental GT has standard front and rear seat side-impact airbags and head airbags, which act as a forgiving barrier between the passengers and the door. Combined with high-strength steel door beams this system increases protection from broadside collisions. The 911 doesn't offer rear-seat side-impact airbags, only ones for front seat occupants.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Continental GT. But it costs extra on the 911.

The Continental GT’s blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The 911 doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the Continental GT’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 911 doesn’t offer a cross-path warning system.

Both the Continental GT and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, night vision systems, lane departure warning systems and around view monitors.

The Bentley Continental GT weighs 1285 to 1968 pounds more than the Porsche 911. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

For better traction, the Continental GT has larger standard tires than the 911 (F:265/40R21 & R:305/35R21 vs. F:235/40R19 & R:295/35R20). The Continental GT’s optional tires are larger than the largest tires available on the 911 (F:275/35R22 & R:315/30R22 vs. F:245/35R20 & R:305/30R21).

For better ride, handling and brake cooling the Continental GT has standard 21-inch wheels. Smaller 19-inch front and 20-inch rear wheels are standard on the 911. The Continental GT’s optional 22-inch wheels are larger than the 20-inch front wheels and 21-inch rear wheels optional on the 911.

The front and rear suspension of the Continental GT uses air springs for a smoother, controlled ride than the 911, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Continental GT offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Porsche doesn’t offer an active suspension on the 911.

The Continental GT has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Continental GT’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 911 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Continental GT’s wheelbase is 15.7 inches longer than on the 911 (112.2 inches vs. 96.5 inches).

For better handling and stability, the track (width between the wheels) on the Continental GT is 3.2 inches wider in the front and 4.3 inches wider in the rear than the average track on the 911.

The Continental GT’s front to rear weight distribution is more even (53% to 47%) than the 911’s (36.4% to 63.6%). This gives the Continental GT more stable handling and braking.

To almost totally eliminate engine vibration in the passenger area, the Continental GT has an electronically controlled liquid-filled main engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The 911 uses conventional solid rubber engine mounts.

The design of the Bentley Continental GT amounts to more than styling. The Continental GT has an aerodynamic coefficient of drag of .29 Cd. That is lower than the 911 (.31). A more efficient exterior helps the Continental GT go faster and keeps the interior quieter. It also helps the Continental GT get better fuel mileage.

As tested by Car and Driver, the interior of the Continental GT Coupe is quieter than the 911 S Coupe:

The Continental GT’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the 911.

The Continental GT offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 911 doesn’t offer a heads-up display.

The Continental GT’s standard power windows have a locking feature to keep children in the rear seat from operating them, but the driver can still raise and lower all of them with the lock engaged. Porsche does not offer a locking feature on the 911’s standard power windows.

The Continental GT offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the 911.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Bentley Continental GT offers an optional wireless phone charging system (Qi) in the center console. The 911 doesn’t offer wireless personal charging.

The Continental GT’s optional Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The 911 doesn’t offer an automated parking system.
