The 370Z has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The 911 doesn’t offer a whiplash protection system.

Both the 370Z and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.


Nissan’s powertrain warranty covers the 370Z 1 year and 10,000 miles longer than Porsche covers the 911. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 911 ends after only 4 years or 50,000 miles.

There are almost 6 times as many Nissan dealers as there are Porsche dealers, which makes it much easier should you ever need service under the 370Z’s warranty.


J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks Nissan 7th in initial quality, above the industry average. With 10 more problems per 100 vehicles, Porsche is ranked 15th, below the industry average.

Fuel Economy and Range

The 370Z has 2.1 gallons more fuel capacity than the 911 RWD’s standard fuel tank (19 vs. 16.9 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Nissan 370Z higher (3 out of 10) than the Porsche 911 (1). This means the 370Z produces up to 22.5 pounds less smog-producing pollutants than the 911 every 15,000 miles.


To facilitate fast shifting and allow the driver to focus on the road, the 370Z has a standard up-shift light to indicate when the engine is approaching redline. The 911 doesn’t offer an up-shift light.

Tires and Wheels

The 370Z has a standard 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 911; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For a smoother ride and more stable handling, the 370Z’s wheelbase is 3.9 inches longer than on the 911 (100.4 inches vs. 96.5 inches).

The 370Z’s front to rear weight distribution is more even (54.3% to 45.7%) than the 911’s (40.1% to 59.9%). This gives the 370Z more stable handling and braking.

For better maneuverability, the 370Z’s turning circle is .8 feet tighter than the 911 GT2 RS’ (32.8 feet vs. 33.6 feet). The 370Z Sport/NISMO’s turning circle is 2.3 feet tighter than the 911’s (34.1 feet vs. 36.4 feet).


The 370Z is 9.6 inches shorter than the 911, making the 370Z easier to handle, maneuver and park in tight spaces.

To almost totally eliminate engine vibration in the passenger area, the 370Z has an electronically controlled liquid-filled main engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The 911 uses conventional solid rubber engine mounts.

The 370Z Sport/Sport Touring/NISMO/50th Anniversary Edition uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 911 doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the 370Z is quieter than the 911 GT2 RS:

48 dB

68 dB


82 dB

70 MPH Cruising

79 dB

Passenger Space

The 370Z has .2 inches more front headroom and 3.6 inches more front shoulder room than the 911 Coupe.

Cargo Capacity

The 370Z has a much larger trunk than the 911 Coupe with its rear seat up (6.9 vs. 5.1 cubic feet).


The 370Z’s standard power windows have a locking feature to keep children from operating them. Porsche does not offer a locking feature on the 911’s standard power windows.

If the windows are left open on the 370Z the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

The Intelligent Key standard on the 370Z allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Porsche 911’s available Porsche Entry and Drive doesn’t unlock the trunk.

The 370Z’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 911’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Consumer Reports rated the 370Z’s headlight performance “Very Good,” a higher rating than the 911’s headlights, which were rated “Fair.”

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the 370Z has standard extendable sun visors. The 911 doesn’t offer extendable visors.

Economic Advantages

Insurance will cost less for the 370Z owner. The Complete Car Cost Guide estimates that insurance for the 370Z will cost $775 to $13445 less than the 911 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Nissan 370Z will be $39339 to $98266 less than for the Porsche 911.


Consumer Reports® recommends both the Nissan 370Z and the Porsche 911, based on reliability, safety and performance.
