Compare the2025 Porsche 911VS 2025 Aston Martin DB12

Over 200 people are killed each year when backed over by motor vehicles. The 911 (except Manual/GT3) offers an optional Maneuvering Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The DB12 doesn’t offer backup collision prevention brakes.

The 911 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The DB12 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 DB12 doesn’t offer a night vision system.

Both the 911 and DB12 offer rear cross-traffic warning, but the 911 with Rear Cross Traffic Alert also has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The DB12’s Rear Cross Traffic Assist doesn’t automatically brake.

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 DB12 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 DB12 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, lane departure warning systems, rearview cameras, driver alert monitors, available crash mitigating brakes, blind spot warning systems and 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 DB12’s 3-year basic warranty expires 1 year sooner.

The 911’s corrosion warranty is 2 years longer than the DB12’s (12 vs. 10 years).

There are almost 6 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.

J.D. Power and Associates rated the 911 second among premium sporty cars in their 2024 Initial Quality Study. The DB12 isn’t in the top three in its category.

The 911 Turbo S’ standard 3.7 turbo 6-cylinder produces 77 lbs.-ft. more torque (590 vs. 513) than the DB12’s 4.0 turbo V8.

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The DB12 doesn’t offer a boxer engine configuration.

On the EPA test cycle the 911 Cabriolet gets better mileage than the DB12:

Regenerative brakes improve the 911 GTS’ fuel efficiency by converting inertia back into energy instead of wasting it. The DB12 doesn’t offer a regenerative braking system.

The 911’s optional fuel tank has 1.6 gallons more fuel capacity than the DB12 (22.1 vs. 20.5 gallons).

The 911 offers a manual transmission for better acceleration, control and sportiness. The DB12 doesn’t offer a manual transmission.

The 911 offers a standard 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 DB12 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 DB12 is not available with all wheel drive.

For better stopping power the 911 CCB’s front brake rotors are larger than those on the DB12:

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 DB12 doesn’t offer ceramic brake rotors.

The 911 GT3 RS’ optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the DB12’s 35 series front tires.

The 911 (except Base/GT3) 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 DB12 doesn’t offer an active sway bar system.

For better maneuverability, the 911 GT3’s turning circle is 4.3 feet tighter than the DB12’s (34.1 feet vs. 38.4 feet). The 911’s turning circle is 1.7 feet tighter than the DB12’s (36.7 feet vs. 38.4 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 400 to 950 pounds less than the Aston Martin DB12.

The 911 is shorter than the DB12, 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 DB12 doesn’t offer active grille shutters.

The 911’s standard rear seats fold to accommodate long and bulky cargo. The DB12 doesn’t offer folding rear seats.

A standard locking glovebox keeps your small valuables safer in the 911. The DB12 doesn’t offer locking storage for small valuables.

To improve rear visibility by keeping the rear window clear, the 911 (except Cabriolet/GT3) offers an optional rear wiper. The DB12 doesn’t offer a rear wiper.

The 911’s sun-visors swivel front-to-side to block glare from the side windows. The DB12’s visors are fixed into the windshield header.

The 911’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The DB12 has an automatic rear view mirror, but its side mirrors don’t dim.

The 911 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the DB12.

The Porsche 911 has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Aston Martin charges extra for Homelink® on the DB12.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The DB12’s automatic parking system requires operating the brakes and transmission to safely park and it doesn’t offer remote control parking.

J.D. Power and Associates rated the 911 second among premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The DB12 isn’t in the top three.
