Both the 718 Cayman and the Q60 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’s corrosion warranty is 5 years longer than the Q60’s (12 vs. 7 years).


The battery on the 718 Cayman is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the 718 Cayman’s battery 20 to 30 degrees cooler, its life is increased by years. The Q60’s battery is in the hot engine compartment.

Regenerative brakes improve the 718 Cayman’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q60 doesn’t offer a regenerative braking system.

Regardless of its engine, the 718 Cayman’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Infiniti only offers an automatic engine start/stop system on the Q60 2.0t.


The 718 Cayman offers a manual transmission for better acceleration, control and fuel economy. The Q60 doesn’t offer a manual transmission.

The 718 Cayman offers an optional sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Q60 doesn’t offer an SMG.

The 718 Cayman PDK’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Q60 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the 718 Cayman’s standard front brake rotors are larger than those on the Q60:

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 Q60 doesn’t offer ceramic brake rotors.

The 718 Cayman stops much shorter than the Q60:

Tires and Wheels

For better traction and acceleration, the 718 Cayman has larger standard rear tires than the Q60 (265/45R18 vs. 255/40R19). The 718 Cayman’s optional rear tires are larger than the largest rear tires available on the Q60 (305/30R20 vs. 275/30R20).

Suspension and Handling

The 718 Cayman has standard front and rear gas-charged shocks for better control over choppy roads. The Q60’s suspension doesn’t offer gas-charged shocks.

The 718 Cayman S handles at 1.04 G’s, while the Q60 Red Sport 400 AWD pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The 718 Cayman S executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the Q60 Red Sport 400 (23.7 seconds @ .89 average G’s vs. 25.5 seconds @ .76 average G’s).

For better maneuverability, the 718 Cayman’s turning circle is .6 feet tighter than the Q60’s (36.1 feet vs. 36.7 feet). The 718 Cayman’s turning circle is 2 feet tighter than the Q60 AWD’s (36.1 feet vs. 38.1 feet).


The Porsche 718 Cayman may be more efficient, handle and accelerate better because it weighs about 800 to 1000 pounds less than the Infiniti Q60.

The 718 Cayman is 12 inches shorter than the Q60, making the 718 Cayman easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The 718 Cayman has a much larger trunk than the Q60 (14.9 vs. 8.7 cubic feet).

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 Q60 doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Servicing Ease

The 718 Cayman has a maintenance free battery for long life without checking the battery’s water level. The Q60 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.


The 718 Cayman’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Q60 doesn’t offer an easy entry system.

The 718 Cayman’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 Q60 does not have an oil pressure gauge.

Porsche Entry and Drive optional on the 718 Cayman 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 Infiniti Q60’s Infiniti Intelligent Key doesn’t unlock the trunk.

To improve rear visibility by keeping the rear window clear, the 718 Cayman offers an optional rear wiper. The Q60 doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 718 Cayman offers available headlight washers to keep headlight output high. The Q60 doesn’t offer headlight washers.

Optional air-conditioned seats in the 718 Cayman keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Q60 doesn’t offer air-conditioned seats.

Economic Advantages

The 718 Cayman will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the 718 Cayman will retain 55.27% to 55.4% of its original price after five years, while the Q60 only retains 42.74% to 44.56%.


The Cayman was chosen as one of Car and Driver’s “Top Ten” for 13 of the last 14 years. The Q60 has never been a Car and Driver “Top Ten” pick.

The 718 Cayman was chosen as one of Automobile Magazine’s “All Stars” for 3 of the last 6 years. The Q60 has never been an “All Star.”
