2014 Aston Martin

Safety Comparison

The 6 Series has standard tall side airbags which act as a forgiving barrier between the driver and front passenger's upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. The DB9 doesn't offer side airbag protection for the head.

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 DB9 doesn’t offer a whiplash protection system.

The 6 Series offers all wheel drive to maximize traction under poor conditions, especially in ice and snow. The DB9 doesn’t offer all wheel drive.

The BMW 6 Series has Daytime Running Lights to help keep it more visible under all conditions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The DB9 doesn’t offer Daytime Running Lights.

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 DB9 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 DB9 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 DB9 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 DB9 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 DB9 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 DB9 have standard driver and passenger frontal airbags, front side-impact airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

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 DB9’s 3 year basic warranty expires 1 year sooner.

The 6 Series’ corrosion warranty is 2 years longer than the DB9’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. Aston Martin doesn’t pay scheduled maintenance for the DB9.

There are almost 29 times as many BMW dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the 6 Series’ warranty.

Engine Comparison

The 650i’s standard 4.4 turbo V8 produces 23 lbs.-ft. more torque (480 vs. 457) than the DB9’s 5.9 DOHC V12. The M6’s standard 4.4 turbo V8 produces 50 more horsepower (560 vs. 510) and 43 lbs.-ft. more torque (500 vs. 457) than the DB9’s 5.9 DOHC V12. The M6 Competition Package’s standard 4.4 turbo V8 produces 65 more horsepower (575 vs. 510) and 43 lbs.-ft. more torque (500 vs. 457) than the DB9’s 5.9 DOHC V12.

Regenerative brakes improve the 6 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The DB9 doesn’t offer a regenerative braking system.

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 DB9 doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

For better stopping power the M6 Carbon Brakes’ front brake rotors are larger than those on the DB9:

M6 Carbon Brakes


Front Rotors

16.1 inches

15.7 inches

Rear Rotors

15.6 inches

14.2 inches

Tires and Wheels Comparison

For better traction, the M6’s front tires are larger than the largest tires available on the DB9 (F:265/40R19 & R:295/35R19 vs. F:245/35R20 & R:295/30R20).

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 DB9 doesn’t offer run-flat tires.

Suspension and Handling Comparison

The 6 Series has standard front and rear gas-charged shocks for better control over choppy roads. The DB9’s suspension doesn’t offer gas-charged shocks.

The 6 Series offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Aston Martin doesn’t offer an active suspension on the DB9.

For a smoother ride and more stable handling, the 6 Series’ wheelbase is longer than on the DB9:

6 Series



112.4 inches

107.9 inches


112.2 inches

107.9 inches

For better handling and stability, the average track (width between the wheels) on the 6 Series is 1.3 inches wider in the front and 3.1 inches wider in the rear than the track on the DB9.

The 650i Coupe goes through Road & Track’s slalom 1.3 MPH faster than the DB9 Coupe (66.8 vs. 65.5 MPH).

Chassis Comparison

The design of the BMW 6 Series amounts to more than styling. The 6 Series has an aerodynamic coefficient of drag of .32 Cd. That is lower than the DB9 (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the 6 Series get better fuel mileage.

Passenger Space Comparison

Because it has more passenger and cargo room, the 6 Series Coupe is rated a Compact car by the EPA, while the DB9 is rated a Minicompact.

The 6 Series Coupe has 19 cubic feet more passenger volume than the DB9 (87 vs. 68).

The 6 Series Coupe has 3.3 inches more front headroom, 4.6 inches more rear headroom, 5.6 inches more rear legroom and .9 inches more rear shoulder room than the DB9 Coupe.

Cargo Capacity Comparison

The 6 Series Coupe has a much larger trunk than the DB9 Coupe (16.2 vs. 6.1 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 DB9 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. Aston Martin does not offer a locking feature on the DB9’s standard power 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 DB9 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.

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 DB9 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 DB9 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.

A power rear sunshade is optional in the 6 Series Coupe to help block heat and glare for the rear passengers. The DB9 doesn’t offer a rear sunshade.

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 DB9’s mirror doesn’t automatically adjust for backing.

The 6 Series has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The DB9 has an automatic rear view mirror, but its side mirrors don’t dim.

The 6 Series’ optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The DB9 doesn’t offer air conditioned front seats.

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 DB9 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 DB9 doesn’t offer an adaptive cruise control.

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 DB9 doesn’t offer factory integrated smartphone program access.

The 6 Series’ standard GPS navigation system has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service available in a limited number of metro areas.) The DB9’s navigation system doesn’t offer real-time traffic updates.

With standard voice command, the 6 Series offers the driver hands free control of the radio, cell phone and the navigation computer by simply speaking. The DB9 doesn’t offer a voice control system.

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 DB9 doesn’t offer an automated parking system.

Recommendations Comparison

J.D. Power and Associates rated the 6 Series third among midsize premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The DB9 isn’t in the top three.

The 6 Series was chosen as one of Automobile Magazine’s “All Stars” in 2005. The DB9 has never been an “All Star.”
