Safety Comparison

The Mustang Premium’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Boxster doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the Mustang Premium’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 Boxster doesn’t offer a cross-path warning system.

The Mustang has standard 911 Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions or send emergency personnel to the scene if any airbags deploy. The Boxster 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 Mustang and the Boxster 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, available collision warning systems and rear parking sensors.

The Ford Mustang weighs 502 to 1016 pounds more than the Porsche Boxster. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Lighter cars are also affected more by crosswinds.

Warranty Comparison

Ford’s powertrain warranty covers the Mustang 1 year and 10,000 miles longer than Porsche covers the 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 Boxster ends after only 4 years or 50,000 miles.

There are almost 20 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.

Reliability Comparison

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 Boxster doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

Fuel Economy and Range Comparison

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

The Mustang ECOBoost’s standard fuel tank has 1.2 gallons more fuel capacity than the Boxster Spyder’s standard fuel tank (15.5 vs. 14.3 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 Boxster doesn’t offer a cap-less fueling system.

Road and Track

Tires and Wheels Comparison

For better traction, the Mustang’s optional tires are larger than the largest tires available on the Boxster (265/35R20 vs. 235/45R18).

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 Boxster, it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling Comparison

The Mustang’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Boxster doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Mustang’s wheelbase is 9.7 inches longer than on the Boxster (107.1 inches vs. 97.4 inches).

For better handling and stability, the track (width between the wheels) on the Mustang is 2.3 inches wider in the front and 4.5 inches wider in the rear than the average track on the Boxster.

The Mustang’s front to rear weight distribution is more even (53.5% to 46.5%) than the Boxster’s (45% to 55%). This gives the Mustang more stable handling and braking.

Chassis Comparison

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

Passenger Space Comparison

The Mustang has standard seating for 4 passengers; the Boxster can only carry 2.

Cargo Capacity Comparison

The Mustang Convertible has a much larger trunk with its top down than the Boxster (11.4 vs. 9.9 cubic feet).

Ergonomics Comparison

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 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 Boxster can’t use the remote to operate the windows.

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 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 Boxster doesn’t offer extendable visors.

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

Economic Advantages Comparison

The Mustang will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Mustang will retain 47.07% to 58.17% of its original price after five years, while the Boxster only retains 45.56% to 47.83%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Ford Mustang will be $18094 to $25224 less than for the Porsche Boxster.

Recommendations Comparison

IntelliChoice recognized the Ford Mustang as a “Best Value of the Year” for the 2015 model year.

The Mustang was chosen as one of Automobile Magazine’s “All Stars” three times - most recently in 2015. The Boxster hasn’t been picked since 2014.

The Ford Mustang outsold the Porsche Boxster by over 39 to one during the 2016 model year.
