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 Cayman 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 Cayman 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 Cayman 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 Cayman 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 493 to 841 pounds more than the Porsche Cayman. 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 Cayman. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the Cayman 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 Cayman 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 Cayman 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 Cayman GT4’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 Cayman doesn’t offer a cap-less fueling system.

Front Rotors

12.6 inches

Car and Driver

Tires and Wheels Comparison

For better traction, the Mustang’s optional tires are larger than the largest tires available on the Cayman (265/35R20 vs. 245/35R20).

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 Cayman 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 Cayman (107.1 inches vs. 97.4 inches).

For better handling and stability, the track (width between the wheels) on the Mustang is 2.2 inches wider in the front and 4.4 inches wider in the rear than the average track on the Cayman.

The Mustang’s front to rear weight distribution is more even (53.5% to 46.5%) than the Cayman’s (45.1% to 54.9%). 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 Cayman doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the Mustang EcoBoost Fastback is quieter than the Cayman S:



At idle

43 dB

53 dB


82 dB

89 dB

70 MPH Cruising

73 dB

77 dB

Passenger Space Comparison

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

The Mustang Fastback has 36.5 cubic feet more passenger volume than the Cayman (84.5 vs. 48).

Cargo Capacity Comparison

A low lift-over trunk design makes loading and unloading the Mustang easier. The Mustang’s trunk lift-over height is 30 inches, while the Cayman’s liftover is 32.7 inches.

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 Cayman 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 Cayman 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 Cayman’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 Cayman doesn’t offer extendable visors.

Economic Advantages Comparison

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Ford Mustang will be $18172 to $24796 less than for the Porsche Cayman.
