The 911 has standard Warn and Brake Assist, 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 DB11 doesn't offer collision warning or crash mitigation brakes.

The 911 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The DB11 doesn’t offer all-wheel drive.

A passive infrared night vision system optional on the 911 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 DB11 doesn’t offer a night vision system.

The 911’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The DB11 doesn’t offer a lane departure warning system.

The 911 has standard Porsche Connect, 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 DB11 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 911 and the DB11 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available around view monitors.

The 911 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The DB11’s 3-year basic warranty expires 1 year sooner.

The 911’s corrosion warranty is 2 years longer than the DB11’s (12 vs. 10 years).

There are over 5 times as many Porsche dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the 911’s warranty.

The 911 offers a manual transmission for better acceleration, control and fuel economy (late availability). The DB11 doesn’t offer a manual transmission.

The 911 offers an optional sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The DB11 doesn’t offer an SMG.

All wheel drive, available in the 911, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Aston Martin DB11 is not available with all wheel drive.

The 911 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The DB11 doesn’t offer ceramic brake rotors.

The 911 stops much shorter than the DB11:

The 911’s optional 245/35R20 front and 305/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the DB11’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 911 offers optional 21-inch rear wheels. The DB11’s largest wheels are only 20-inches.

The 911 S offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The DB11 doesn’t offer an active sway bar system.

For better maneuverability, the 911’s turning circle is 1.7 feet tighter than the DB11’s (36.8 feet vs. 38.5 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 500 to 550 pounds less than the Aston Martin DB11.

The 911 is 9.1 inches shorter than the DB11, making the 911 easier to handle, maneuver and park in tight spaces.

The front grille of the 911 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The DB11 doesn’t offer active grille shutters.

The 911’s standard rear seats fold to accommodate long and bulky cargo. The DB11 doesn’t offer folding rear seats.

A standard locking glovebox keeps your small valuables safer in the 911. The DB11 doesn’t offer locking storage for small valuables.

To improve rear visibility by keeping the rear window clear, the 911 offers an optional rear wiper. The DB11 doesn’t offer a rear wiper.

While driving with high beams on, sensitive light sensors available for the 911 detect other vehicles which could be blinded and automatically switch to low beams. The DB11 doesn’t offer automatic dimming high beams.

The 911’s sun-visors swivel front-to-side to block glare from the side windows. The DB11’s visors are fixed into the windshield header.

The 911 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 DB11 has an automatic rear view mirror, but its side mirrors don’t dim.

To keep a safe, consistent following distance, the 911 offers an optional Adaptive 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 DB11 doesn’t offer an adaptive cruise control.
