The SL’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The DB11 doesn’t offer pre-crash pretensioners.

The SL has standard NECK-PRO Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO Head Restraints system moves the headrests forward to prevent neck and spine injuries. The DB11 doesn’t offer a whiplash protection system.

The SL has a standard Active Brake Assist, which uses 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.

An active infrared night vision system optional on the SL helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights 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 SL’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 SL’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The DB11 doesn’t offer a driver alert monitor.

The SL has standard Mercedes-Benz Emergency Call, 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 SL and the DB11 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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 blind spot warning systems.

The SL 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.

There are almost 11 times as many Mercedes dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the SL’s warranty.

A nine-speed automatic is standard on the Mercedes SL, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the DB11.

The SL’s 255/35R19 front and 285/30R19 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 standard 40 series front and 35 series rear tires.

The SL offers an available adjustable 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 DB11.

The SL offers an optional automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The DB11 doesn’t offer a load leveling suspension.

For better maneuverability, the SL’s turning circle is 2.3 feet tighter than the DB11’s (36.2 feet vs. 38.5 feet).

The SL is 4.7 inches shorter than the DB11, making the SL easier to handle, maneuver and park in tight spaces.

The SL’s standard power retractable hardtop allows a seamless transition from an open car, to a completely sealed coupe. The DB11 doesn’t offer a retractable hardtop.

The SL has a much larger trunk with its top up than the DB11 Volante with its top up (13.5 vs. 9.9 cubic feet).

With its convertible body style, valet key and remote trunk release lockout, the SL offers cargo security. The DB11’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the SL. The DB11 doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the SL has a standard power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The DB11 doesn’t offer a power trunk, so its trunk has to be closed manually.

The SL has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The DB11 doesn’t offer a remote starting system.

Heated windshield washer fluid is standard on the SL to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The DB11 doesn’t offer heated windshield washer fluid.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The SL has standard headlight washers to keep headlight output high. The DB11 doesn’t offer headlight washers.

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

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the SL has standard extendable sun visors. The DB11 doesn’t offer extendable visors.

The SL’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 SL 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 SL offers an optional Active Distance Assist Distronic, 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.

The SL’s optional Active Parking Assist can parallel park or back into a parking spot by itself. The DB11’s automatic parking system requires operating the brakes and transmission to safely park.
