Both the 718 Cayman and the Z 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, rearview cameras, available crash mitigating brakes and blind spot warning systems.

The 718 Cayman comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Z’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The 718 Cayman’s corrosion warranty is 7 years longer than the Z’s (12 vs. 5 years).

In heavy traffic or at stop lights the 718 Cayman’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Z doesn’t offer an automatic engine start/stop system.

For better stopping power the 718 Cayman’s front brake rotors are larger than those on the Z:

The 718 Cayman offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Z doesn’t offer ceramic brake rotors.

For better traction and acceleration, the 718 Cayman has larger standard rear tires than the Z (265/45R18 vs. 245/45R18). The 718 Cayman GT4’s rear tires are larger than the largest rear tires available on the Z (295/30R20 vs. 275/35R19).

The 718 Cayman GT4’s 245/35R20 front and 295/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the Z Performance Coupe’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 718 Cayman offers optional 20-inch wheels. The Z’s largest wheels are only 19-inches.

The 718 Cayman has standard front and rear gas-charged shocks for better control over choppy roads. The Z’s suspension doesn’t offer gas-charged shocks.

The 718 Cayman offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Z’s suspension doesn’t offer adjustable shock absorbers.

To make loading groceries and cargo easier when your hands are full, the 718 Cayman’s available trunk can be opened just by holding your hand near the emblem on the trunk, leaving your hands completely free.

The 718 Cayman’s power parking brake sets with one touch and releases with one touch. The Z has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The 718 Cayman’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Z’s

The 718 Cayman’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Z Performance.

The 718 Cayman’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver.

On extremely cold winter days, the 718 Cayman’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Z doesn’t offer a heated steering wheel.
