Compare the2023 Aston Martin DB11VS 2023 Porsche 911

The Aston Martin DB11 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The 911 doesn’t offer knee airbags.

The DB11 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 911’s blind spot costs extra.

Both the DB11 and the 911 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 and rearview cameras.

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

For better traction, the DB11 has larger front tires than the 911 (F:255/40R20 & R:295/35R20 vs. F:235/40R19 & R:295/35R20).

The DB11’s 255/40R20 front and 295/35R20 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the DB11 has standard 20-inch wheels. Smaller 19-inch front wheels are standard on the 911.

For a smoother ride and more stable handling, the DB11’s wheelbase is 13.9 inches longer than on the 911 (110.4 inches vs. 96.5 inches). The DB11’s wheelbase is 13.7 inches longer than on the 911 GT3 (110.4 inches vs. 96.7 inches).

For better handling and stability, the track (width between the wheels) on the DB11 is 2.9 inches wider in the front and 3.2 inches wider in the rear than the average track on the 911.

The DB11’s front to rear weight distribution is more even (51% to 49%) than the 911’s (39.5% to 60.5%). This gives the DB11 more stable handling and braking.

The DB11 has .7 inches more front headroom, 2.9 inches more front legroom, 1.7 inches more front shoulder room, .7 inches more rear headroom, 1.1 inches more rear legroom and .7 inches more rear shoulder room than the 911.

The DB11 Volante has a much larger trunk with its top down than the 911 Cabriolet with its top down (8.5 vs. 4.6 cubic feet).

To make loading groceries and cargo easier when your hands are full, the DB11’s trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The 911 doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Unlike the driver-only memory system optional at extra cost in the 911, the DB11 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The DB11’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the 911.

If the windows are left open on the DB11 the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

In case of a sudden change of weather, the DB11 has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. On a hot day the DB11 has a standard remote opening feature, to lower the top from outside. The 911 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.
