Safety Comparison

The Cayman has standard head airbag curtains which act as a forgiving barrier between the driver and outboard passenger's upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. Head airbags cost extra in the Mustang.

The Cayman has standard four wheel antilock disc brakes for quicker stops and controlled steering ability, especially under poor traction conditions. Antilock brakes cost extra on the Ford Mustang.

The Cayman has standard Porsche Stability Management (PSM), which uses the antilock brake hardware along with powerful software and additional sensors to detect the beginning of a skid. PSM then intervenes by automatically applying the brake at one appropriate wheel, preventing a skid. The Mustang doesn’t offer skid prevention. A National Highway Traffic Safety Administration study showed that skid control systems reduced single-vehicle car crashes by 30%.

The Cayman offers an optional backup radar to help warn drivers about vehicles, pedestrians or other obstacles behind their vehicle. This collision warning system uses radar to detect obstacles behind the rear bumper. The Mustang doesn’t offer a rear collision sensor.

Both the Cayman and the Mustang have standard driver and passenger frontal airbags and front seatbelt pretensioners.

Warranty Comparison

The Cayman comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The Mustang’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

The Cayman’s corrosion warranty is 5 years longer than the Mustang’s (10 vs. 5 years).

Engine Comparison

The Cayman’s standard 2.7 DOHC 6 cyl. produces 35 more horsepower (245 vs. 210) than the Mustang’s standard 4.0 SOHC V6.

As tested in Road & Track the Cayman S is faster than the Mustang GT (manual transmissions tested):

The flat cylinder configuration of the boxer engine in the Cayman lowers its center of gravity, enhancing handling stability. The Mustang doesn’t offer a boxer engine configuration.

Fuel Economy and Range Comparison

On the EPA test cycle the Cayman gets better fuel mileage than the Mustang:

The Cayman has almost a gallon more fuel capacity than the Mustang (16.9 vs. 16 gallons), for longer range between fill-ups.

Brakes and Stopping Comparison

For better stopping power the Cayman’s front brake rotors are larger than those on the Mustang:

11.73 inches

13.78 inches

11.5 inches

12.4 inches

The Cayman’s brakes have 46% more swept area (the area covered by the brake pads) than the Mustang (722 vs. 495 square inches), so the Cayman has more braking power available.

The Cayman’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the Mustang are solid, not vented.

The Cayman S offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Mustang doesn’t offer ceramic brake rotors.

The Cayman with its standard antilock brakes stops much shorter than the Mustang with antilock brakes:

Tires and Wheels Comparison

For better traction and acceleration, the Cayman has larger standard rear tires than the Mustang (235/50R17 vs. 215/65R16). The Cayman’s optional rear tires are larger than the largest rear tires available on the Mustang (265/40R18 vs. 235/55R17).

The Cayman’s standard 205/55R17 front and 235/50R17 rear tires provide better handling because they have a lower 55 series front and 50 series rear profile (height to width ratio) which provides a stiffer sidewall than the Mustang’s standard 65 series tires. The Cayman’s optional tires have a lower 35 series profile than the Mustang GT’s optional 50 series tires.

For better ride, handling and brake cooling the Cayman has standard 17 inch wheels. Smaller 16 inch wheels are standard on the Mustang. The Cayman’s optional 19 inch wheels are larger than the 18 inch wheels optional on the Mustang GT.

The Cayman has a standard tire pressure monitoring system, which will alert the driver to a drop in tire pressure before damage to the tire or an accident might occur. The Mustang doesn’t offer a low tire pressure warning system.

Suspension and Handling Comparison

For superior ride and handling, the Porsche Cayman has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Ford Mustang has a solid rear axle, with a non-independent rear suspension.

The Cayman has standard front and rear stabilizer bars, which help keep the Cayman flat and controlled during cornering. The Mustang base model’s suspension doesn’t offer a rear stabilizer bar.

The Cayman offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Mustang’s suspension doesn’t offer adjustable shock absorbers.

The Cayman S handles at .99 G’s, while the Mustang Coupe pulls only .79 G’s of cornering force in a Car and Driver skidpad test.

The Cayman S goes through Road & Track’s slalom 11 MPH faster than the Mustang Coupe (74.2 vs. 63.2 MPH).

Chassis Comparison

The Porsche Cayman may be more efficient, handle and accelerate better because it weighs about 400 to 700 pounds less than the Ford Mustang.

For excellent aerodynamics, the Cayman has standard flush composite headlights. The Mustang has recessed headlights which spoil its aerodynamic shape and create extra drag.

As tested by AutoWeek while at idle, the interior of the Cayman S is quieter than the Mustang GT Coupe (52 vs. 55 dB).

Cargo Capacity Comparison

The Cayman has a much larger trunk than the Mustang Coupe (14.5 vs. 12.3 cubic feet).
