Compare the2023 Ford MustangVS 2022 Porsche 718 Boxster

The Mustang’s 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 718 Boxster doesn’t offer a lane departure warning system.

The Mustang 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 718 Boxster’s blind spot costs extra.

To help make backing out of a parking space safer, the Mustang’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 718 Boxster doesn’t offer a cross-path warning system.

The Mustang’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 718 Boxster doesn’t offer a driver alert monitor.

Both the Mustang and the 718 Boxster have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available rear parking sensors.

Ford’s powertrain warranty covers the Mustang 1 year and 10,000 miles longer than Porsche covers the 718 Boxster. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 718 Boxster ends after only 4 years or 50,000 miles.

There are over 15 times as many Ford dealers as there are Porsche dealers, which makes it much easier should you ever need service under the Mustang’s warranty.

The Mustang has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The 718 Boxster doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

The Mustang Mach 1’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the 718 Spyder’s 35 series front tires.

The Mustang has a standard space-saver spare (not available on Handling Package/H.O. Package/Mach 1) so you can replace a flat tire and drive to have the flat repaired or replaced.

The front grille of the Mustang (except Performance Pack) uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The 718 Boxster doesn’t offer active grille shutters.

The Mustang Convertible uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 718 Boxster doesn’t offer active noise cancellation.

The Mustang’s LED headlights produce a white, bright light using less electricity than the 718 Boxster’s standard xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Mustang has standard extendable sun visors. The 718 Boxster doesn’t offer extendable visors.

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