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

To help make backing safer, the Mustang Premium/BULLITT’s optional cross-path warning system uses wide-angle radar 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 optional 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, available crash mitigating brakes, blind spot warning systems and 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 almost 16 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.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Ford vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks Ford fourth in initial quality, above the industry average. With 13 more problems per 100 vehicles, Porsche is ranked 15th, below the industry average.

To lower fuel costs and make buying fuel easier, the Ford Mustang uses regular unleaded gasoline (premium recommended for maximum performance). The 718 Boxster requires premium, which can cost 20 to 55 cents more per gallon.

The Mustang EcoBoost’s standard fuel tank has 1.3 gallons more fuel capacity than the 718 Boxster’s standard fuel tank (15.5 vs. 14.2 gallons), for longer range between fill-ups.

The Mustang has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The 718 Boxster doesn’t offer a cap-less fueling system.

For better traction, the Mustang GT’s optional tires are larger than the largest tires available on the 718 Boxster (305/30R19 vs. 245/35R20).

The Mustang GT’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 Boxster’s optional 35 series front tires.

The Mustang offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 718 Boxster; it requires you to depend on roadside assistance and your vehicle will have to be towed.

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 Auto 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 718 Boxster doesn’t offer a remote starting system.

On a hot day the Mustang’s driver can lower all the windows from a distance using the keyless remote. The driver of the 718 Boxster can only operate the windows from inside the vehicle, with the ignition on.

The Mustang’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 718 Boxster’s cruise control switches are unlit, making them difficult to find at night and operate safely.

The Mustang’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The 718 Boxster’s standard manually variable intermittent wipers have to be constantly adjusted.

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.
