2008 Infiniti G37

Safety Comparison

Both the Mustang and the G37 have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, available four-wheel antilock brakes and traction control.

Warranty Comparison

There are almost 25 times as many Ford dealers as there are Infiniti dealers, which makes it much easier to get service under the Mustang’s warranty.

Reliability Comparison

The engines in the Mustang have a single overhead cam for simplicity. The engine in the G37 has dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

The G37’s redline is at 7500 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Mustang has a 6250 RPM redline.

The Mustang GT 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 G37 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 rated the Mustang first among midsize sporty cars in their 2007 Initial Quality Study. The G37 isn’t in the top three in its category.

Engine Comparison

The Mustang GT’s standard 4.6 SOHC V8 produces 50 lbs.-ft. more torque (320 vs. 270) than the G37’s 3.7 DOHC V6. The Mustang Shelby GT’s standard 4.6 SOHC V8 produces 60 lbs.-ft. more torque (330 vs. 270) than the G37’s 3.7 DOHC V6.

Fuel Economy and Range Comparison

To lower fuel costs and make buying fuel easier, the Ford Mustang uses regular unleaded gasoline. The G37 requires premium, which can cost 25 to 50 cents more per gallon.

Tires and Wheels Comparison

For better traction, the Mustang’s optional tires are larger than the largest tires available on the G37 (235/55R17 vs. 225/45R19).

Suspension and Handling Comparison

For better handling and stability, the average track (width between the wheels) on the Mustang is 1.6 inches wider in the front and 1.4 inches wider in the rear than the average track on the G37.

The Mustang Coupe handles at .87 G’s, while the G37 Sport pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the Mustang V6’s turning circle is 2.7 feet tighter than the G37’s (33.4 feet vs. 36.1 feet).

Chassis Comparison

The Ford Mustang may be more efficient, handle and accelerate better because it weighs about 50 to 250 pounds less than the Infiniti G37.

Passenger Space Comparison

Because it has more passenger and cargo room, the Mustang Coupe is rated a Mid-size car by the EPA, while the G37 is rated a Subcompact.

The Mustang Coupe has 12.9 cubic feet more passenger volume than the G37 (97.9 vs. 85).

The Mustang Coupe has .2 inches more front hip room, 1.7 inches more front shoulder room, .2 inches more rear headroom, .5 inches more rear legroom and .7 inches more rear shoulder room than the G37.

Cargo Capacity Comparison

The Mustang Coupe has a much larger trunk than the G37 (13.1 vs. 7.4 cubic feet).

The Mustang Coupe’s standard folding rear seats are split to accommodate bulky cargo. The G37’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

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 G37 does not have an oil pressure gauge.

The Mustang has a lever hand brake in the console, easy to use while keeping both feet free and not impeding entry and exit. The G37’s foot pedal parking brake is not handy to use as a hill holding device with a manual transmission.

The G37’s power locks don’t automatically lock the doors. The Mustang’s standard power locks automatically lock the doors when a certain speed is reached. This is an important feature for occupant safety. Locked doors are proven to open less often in collisions, and they are also effective in preventing crime at traffic lights. (The power lock’s automatic feature may have to be activated by your dealer.)
