2015 Bentley Continental

Safety Comparison

The 6 Series’ front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Continental doesn’t offer pre-crash pretensioners.

The 6 Series has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Continental doesn’t offer a whiplash protection system.

The 6 Series offers optional City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Continental doesn't offer collision warning or crash mitigation brakes.

A passive infrared night vision system optional on the 6 Series helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Continental doesn’t offer a night vision system.

The 6 Series’ optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Continental doesn’t offer a lane departure warning system.

The 6 Series offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The Continental only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The 6 Series’ optional 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 Continental doesn’t offer a system to reveal objects in the driver’s blind spots.

The 6 Series has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Continental doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the 6 Series and the Continental have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all-wheel drive.

Warranty Comparison

The 6 Series comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The Continental’s 3 year basic warranty expires 1 year sooner.

The 6 Series’ corrosion warranty is 9 years longer than the Continental’s (12 vs. 3 years).

BMW pays for scheduled maintenance on the 6 Series for 4 years and 50,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Bentley doesn’t pay scheduled maintenance for the Continental.

There are almost 10 times as many BMW dealers as there are Bentley dealers, which makes it much easier should you ever need service under the 6 Series’ warranty.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the 6 Series has a standard 210-amp alternator. The Continental’s 190-amp alternator isn’t as powerful.

J.D. Power and Associates rated the 6 Series third among midsize premium sporty cars in their 2013 Initial Quality Study. The Continental isn’t in the top three in its category.

In a Motor Trend race course test, the BMW M6 Coupe was clocked 6.08 seconds faster than the Bentley Continental GT Speed (100.52 sec. vs. 106.6 sec.).

Fuel Economy and Range Comparison

On the EPA test cycle the 650i Convertible xDrive 4.4 twin turbo V8 (445 HP) gets better city fuel mileage than the Continental V8 GTC (16 city/24 hwy vs. 14 city/24 hwy).

Regardless of its engine, regenerative brakes improve the 6 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. Bentley only offers a regenerative brake system on the Continental V8.

In heavy traffic or at stoplights the 6 Series’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Continental doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

Tires and Wheels Comparison

The 6 Series’ optional 275/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the Continental’s optional 35 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 6 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Continental doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 6 Series offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Bentley doesn’t offer an active suspension on the Continental.

For a smoother ride and more stable handling, the M6 Convertible’s wheelbase is 4.1 inches longer than on the Continental (112.2 inches vs. 108.1 inches).

The 6 Series’ front to rear weight distribution is more even (50.8% to 49.2%) than the Continental’s (55.7% to 44.3%). This gives the 6 Series more stable handling and braking.

The 650i Coupe handles at .94 G’s, while the Continental GT pulls only .84 G’s of cornering force in a Road & Track skidpad test.

The M6 Convertible handles at .94 G’s, while the Continental GTC pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The 650i Coupe goes through Road & Track’s slalom 3.6 MPH faster than the Continental GT (66.8 vs. 63.2 MPH).

The M6 Coupe executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Continental GT Speed (24.4 seconds @ .83 average G’s vs. 25.7 seconds @ .76 average G’s).

The M6 Convertible executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the Continental GTC (24.6 seconds @ .85 average G’s vs. 26.1 seconds @ .71 average G’s).

Chassis Comparison

The BMW 6 Series may be more efficient, handle and accelerate better because it weighs about 1050 to 1550 pounds less than the Bentley Continental.

Passenger Space Comparison

The 6 Series Coupe has .4 inches more front headroom and .8 inches more front legroom than the Continental GT.

The 6 Series Convertible has 2.1 inches more front headroom and .8 inches more front legroom than the Continental GTC.

Cargo Capacity Comparison

The 6 Series Coupe has a larger trunk than the Continental GT (13 vs. 12.6 cubic feet).

The 6 Series Convertible has a much larger trunk with its top down than the Continental GTC (10.6 vs. 9.2 cubic feet).

Ergonomics Comparison

The 6 Series offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The Continental doesn’t offer a heads-up display.

In case of a sudden change of weather, the 6 Series has a standard remote convertible top that can be raised, from a distance to protect the interior of the vehicle from damage. The Continental doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

Heated windshield washer nozzles are standard on the 6 Series to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Continental doesn’t offer heated windshield washer nozzles.

While driving with high beams on, sensitive light sensors available for the 6 Series detect other vehicles which could be blinded and automatically switch to low beams. The Continental doesn’t offer automatic dimming high beams.

To help drivers avoid possible obstacles, the 6 Series has standard cornering lights to illuminate around corners when the turn signals are activated. The Continental doesn’t offer cornering lights. The 6 Series also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The 6 Series’ power mirror controls are mounted on the armrest for easy access. The Continental’s power mirror controls are on the center console where they can’t be seen without the driver completely removing his eyes from the road.

When the 6 Series is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Continental’s mirror doesn’t automatically adjust for backing.

Standard BMW Apps for the 6 Series allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, tagging songs to buy them later, following twitter accounts and other connected activities without taking their eyes off the road or their hands from the wheel. The Continental doesn’t offer factory integrated smartphone program access.

The 6 Series (except xDrive)’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Continental doesn’t offer an automated parking system.
