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 718 Cayman doesn’t offer a whiplash protection system.

Both the 370Z and the 718 Cayman 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 718 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 718 Cayman 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.

To reliably power the ignition and other systems and to recharge the battery, the 370Z has a standard 150-amp alternator. The 718 Cayman’s 120-amp alternator isn’t as powerful.

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.

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 718 Cayman; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For a smoother ride and more stable handling, the 370Z’s wheelbase is 3 inches longer than on the 718 Cayman (100.4 inches vs. 97.4 inches).

For better handling and stability, the average track (width between the wheels) on the 370Z is .7 inches wider in the front and 1.4 inches wider in the rear than the average track on the 718 Cayman.

For better maneuverability, the 370Z’s turning circle is 3.3 feet tighter than the 718 Cayman’s (32.8 feet vs. 36.1 feet). The 370Z Sport/NISMO’s turning circle is 2 feet tighter than the 718 Cayman’s (34.1 feet vs. 36.1 feet).

The 370Z is 4.9 inches shorter than the 718 Cayman, making the 370Z easier to handle, maneuver and park in tight spaces.

The design of the Nissan 370Z amounts to more than styling. The 370Z has an aerodynamic coefficient of drag of .3 Cd (optional .29 Cd with Sport). That is lower than the 718 Cayman (.3 to .31). A more efficient exterior helps the 370Z go faster and keeps the interior quieter. It also helps the 370Z get better fuel mileage.

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 718 Cayman doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the 370Z is quieter than the 718 Cayman:

The 370Z has 3.6 cubic feet more passenger volume than the 718 Cayman (51.6 vs. 48).

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 718 Cayman’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 718 Cayman can only operate the windows from inside the vehicle, with the ignition on.

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 718 Cayman’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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 718 Cayman doesn’t offer extendable visors.
