Compare the2023 Porsche 718 CaymanVS 2023 Aston Martin Vantage

The Porsche 718 Cayman 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 Vantage doesn’t offer knee airbags.

The 718 Cayman Auto offers optional Porsche Active Safety, 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 Vantage doesn't offer collision warning or crash mitigation brakes.

The 718 Cayman 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 Vantage 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 718 Cayman and the Vantage 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, front and rear parking sensors and available blind spot warning systems.

To make loading groceries and cargo easier when your hands are full, the 718 Cayman’s available trunk can be opened just by holding your hand near the emblem on the trunk, leaving your hands completely free. The Vantage doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The 718 Cayman’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Vantage’s power windows’ switches have to be held the entire time to close them fully.

To improve rear visibility by keeping the rear window clear, the 718 Cayman offers an optional rear wiper. The Vantage doesn’t offer a rear wiper.

While driving with high beams on, sensitive light sensors available for the 718 Cayman detect other vehicles which could be blinded and automatically switch to low beams. The Vantage doesn’t offer automatic dimming high beams.

The 718 Cayman’s sun-visors swivel front-to-side to block glare from the side windows. The Vantage’s visors are fixed into the windshield header.

The 718 Cayman’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 Vantage has an automatic rear view mirror, but its side mirrors don’t dim.

To keep a safe, consistent following distance, the 718 Cayman (except Manual) 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 Vantage doesn’t offer an adaptive cruise control.
