Safety Comparison

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 available rearview cameras.

Warranty Comparison

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.

Ergonomics Comparison

If the windows are left down on the 370Z the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the 718 Cayman can’t use the remote to operate the windows.

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.
