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 911 Turbo doesn’t offer a whiplash protection system.

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 911 Turbo 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 911 Turbo 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 911 Turbo only offers 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 911 Turbo 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 911 Turbo 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 911 Turbo have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

The 6 Series’ corrosion warranty is 2 years longer than the 911 Turbo’s (12 vs. 10 years).

BMW pays for scheduled maintenance on the 6 Series for 4 years and 50,000 miles. BMW will pay for oil changes, tire rotation, lubrication and any other scheduled maintenance. Porsche doesn’t pay scheduled maintenance for the 911 Turbo.

There are over 74 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the 6 Series’ warranty.

To reliably power the ignition and other systems and to recharge the battery, the 6 Series has a standard 210 amp alternator. The 911 Turbo’s 150 amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the 6 Series has a standard 900 amp battery. The 911 Turbo’s 340 amp battery isn’t as powerful.

The battery on the 6 Series is in the trunk, which protects it from hot underhood temperatures which can degrade battery life. By keeping the 6 Series’ battery 20 to 30 degrees cooler, its life is increased by years. The 911 Turbo’s battery is in the hot engine compartment.

Regenerative brakes improve the 6 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The 911 Turbo doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 6 Series 640i/M6’s 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 911 Turbo doesn’t offer an automatic engine start/stop system.

The 6 Series’ standard fuel tank has 1.6 gallons more fuel capacity than the 911 Turbo Cabriolet’s standard fuel tank (18.5 vs. 16.9 gallons), for longer range between fill-ups. The 6 Series M6’s standard fuel tank has 3.4 gallons more fuel capacity than the 911 Turbo Coupe/S Cabriolet’s standard fuel tank (21.1 vs. 17.7 gallons).

For better traction, the 6 Series has larger standard tires than the 911 Turbo (245/45R18 vs. 235/35R19). The M6’s front tires are larger than the largest tires available on the 911 Turbo (265/40R19 vs. 235/35R19).

For better ride, handling and brake cooling the 6 Series offers optional 20-inch wheels. The 911 Turbo’s largest wheels are only 19-inches.

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 911 Turbo doesn’t offer run-flat tires.

The 6 Series offers an available 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 Turbo.

The 6 Series has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The 911 Turbo doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the 6 Series Coupe’s wheelbase is 19.7 inches longer than on the 911 Turbo (112.2 inches vs. 92.5 inches). The 6 Series Convertible’s wheelbase is 19.9 inches longer than on the 911 Turbo (112.4 feet vs. 92.5 inches).

For better handling and stability, the average track (width between the wheels) on the 6 Series is 4.8 inches wider in the front and 4.5 inches wider in the rear than the average track on the 911 Turbo.

The 6 Series’ front to rear weight distribution is more even (50.8% to 49.2%) than the 911 Turbo’s (39.1% to 60.9%). This gives the 6 Series more stable handling and braking.

Unlike the driver-only memory seat and mirrors optional at extra cost in the 911 Turbo, the 6 Series offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The 6 Series’ standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The 911 Turbo doesn’t offer an easy entry system.

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 911 Turbo doesn’t offer a heads-up display.

The 6 Series’ standard power windows have a locking feature to keep children in the rear seat from operating them. Porsche does not offer a locking feature on the 911 Turbo’s standard power windows.

The 6 Series’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The 911 Turbo’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left down on the 6 Series the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the 911 Turbo can’t use the remote to operate the windows.

In case of a sudden change of weather, the 6 Series has a standard remote convertible top which can be raised from a distance to protect the interior of the vehicle from damage. The 911 Turbo’s top can only be opened by remote, 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.

The 6 Series has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The 911 Turbo doesn’t offer automatic headlights.

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 911 Turbo doesn’t offer automatic dimming high beams.

A power rear sunshade is optional in the 6 Series Coupe to help block heat and glare for the rear passengers. The 911 Turbo doesn’t offer a rear sunshade.

The 6 Series’ standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The 911 Turbo doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the 6 Series Automatic offers an optional Active Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The 911 Turbo doesn’t offer an adaptive cruise control.

Optional 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 online activities without taking their eyes off the road or their hands from the wheel. The 911 Turbo doesn’t offer factory integrated smartphone program access.

Bluetooth wireless connectivity is standard on the 6 Series, connecting the driver and passenger’s cell phones to the vehicle systems. This allows them to use the vehicle’s stereo and hand controls to place calls safely and easily. Porsche doesn’t offer wireless connectivity on the 911 Turbo.

The 6 Series’ 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 911 Turbo doesn’t offer an automated parking system.
