Safety Comparison

To maximize occupant safety, the front seat shoulder belts of the Ford Mustang have pretensioners to eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Pontiac GTO doesn’t offer pretensioners.

The Mustang offers optional front seat side-impact airbags, which act as a forgiving barrier between the passengers and the door. Combined with high-strength steel door beams this system increases protection from broadside collisions. The GTO doesn’t offer side-impact airbags.

Using vehicle speed sensors and seat sensors, smart airbags in the Mustang deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The GTO’s airbags don’t have smart features and will always deploy full force.

The Mustang’s gas tank is mounted inside the frame rails in front of the rear axle to optimally protect the fuel tank in a collision. The Pontiac GTO’s gas tank is mounted behind the rear axle, where it is more susceptible to rear collisions.

Both the Mustang and the GTO have standard driver and passenger frontal airbags, available four-wheel antilock brakes and traction control.

Warranty Comparison

The Mustang’s corrosion warranty is unlimited miles longer than the GTO’s (unlimited vs. 100,000 miles).

There are over 38 percent more Ford dealers than there are Pontiac dealers, which makes it easier to get service under the Mustang’s warranty.

Reliability Comparison

For smoother operation, better efficiency and fewer moving parts, the engines in the Mustang have an overhead cam design, rather than the old pushrod design of the engine in the GTO.

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 reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The GTO 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’ surveys of the owners of three-year-old cars provide the long-term dependability statistics, which show that Ford vehicles are more reliable than Pontiac vehicles. J.D. Power ranks Ford 16th in reliability, above the industry average. With 21 more problems per 100 vehicles, Pontiac is ranked 23rd.

Fuel Economy and Range Comparison

The Ford Mustang gets better fuel mileage than the GTO:




19 city/28 hwy



17 city/25 hwy

Brakes and Stopping Comparison

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

The Mustang with optional antilock brakes stops shorter than the GTO with antilock brakes:

Motor Trend

Tires and Wheels Comparison

For better traction, the Mustang GT’s tires are larger than the largest tires available on the GTO (235/55R17 vs. 225/50R17).

Chassis Comparison

The Ford Mustang may be more efficient, handle and accelerate better because it weighs about 50 to 350 pounds less than the Pontiac GTO.

To almost totally eliminate engine vibration in the passenger area, the Mustang V8 (except V6) has a liquid-filled front engine mount. The liquid helps further dampen engine harshness. The GTO uses conventional solid rubber engine mounts.

Passenger Space Comparison

The Mustang Coupe has 1.3 inches more front headroom, .5 inches more front legroom and 1.7 inches more rear shoulder room than the GTO.

Cargo Capacity Comparison

The Mustang Coupe has a much larger trunk than the GTO (13.1 vs. 9 cubic feet).

Ergonomics Comparison

The Mustang’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The GTO does not have an oil pressure gauge.

The Mustang’s power windows raise and lower automatically with one touch, especially convenient at tollbooths or drive-up windows. The power windows on the GTO don’t raise automatically.

The Mustang’s standard power window controls are mounted on the armrest for easy access. The GTO’s available power window controls are spread out on the center console where they can’t be seen without the driver completely removing his eyes from the road.

The Mustang’s standard speed sensitive intermittent wipers speed up as the car does, so that the driver doesn’t have to continually adjust the speed of the wipers. The GTO’s intermittent wipers have to be constantly adjusted.

The Mustang’s standard steering wheel mounted cruise control is close at hand. The GTO’s cruise control is on an over-crowded turn signal stalk.
