Safety
Warranty
The 718 Cayman’s corrosion warranty is 6 years longer than the RC F’s (12 vs. 6 years).
Reliability
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 RC F’s battery is in the hot engine compartment.
Engine
The 718 Cayman GT4 RS’ standard 4.0 DOHC 6-cylinder produces 21 more horsepower (493 vs. 472) than the RC F’s 5.0 DOHC V8.

An engine control system that can shut down some of the engine’s cylinders helps improve the 718 Cayman GT4/GTS 4.0’s fuel efficiency. The RC F doesn’t offer a system that can shut down part of the engine.
Regenerative brakes improve the 718 Cayman’s fuel efficiency by converting inertia back into energy instead of wasting it. The RC F doesn’t offer a regenerative braking system.
In heavy traffic or at stoplights 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 RC F doesn’t offer an automatic engine start/stop system.
Transmission
The 718 Cayman offers a manual transmission for better acceleration, control and sportiness. The RC F 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 RC F doesn’t offer an SMG.
Brakes and Stopping
For better stopping power the 718 Cayman GT4 CCB’s front brake rotors are larger than those on the RC F:

Tires and Wheels
The 718 Cayman GT4’s 295/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the RC F’s 35 series tires.
For better ride, handling and brake cooling the 718 Cayman offers optional 20-inch wheels. The RC F’s largest wheels are only 19-inches.
Chassis
The Porsche 718 Cayman may be more efficient, handle and accelerate better because it weighs about 650 to 750 pounds less than the Lexus RC F.
The 718 Cayman is 1 foot, 1 inches shorter than the RC F, making the 718 Cayman easier to handle, maneuver and park in tight spaces.
To almost totally eliminate engine vibration in the passenger area, the 718 Cayman w/Sport Chrono has an electronically controlled liquid-filled front engine mount and conventional liquid-filled engine mounts (standard liquid front mount on other versions of the 718 Cayman). A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The RC F uses conventional solid rubber engine mounts.
As tested by Car and Driver while under full throttle, the interior of the 718 Cayman is quieter than the RC F (84 vs. 85 dB).
Passenger Space
The 718 Cayman has 1.3 inches more front headroom and .6 inches more front shoulder room than the RC F.
Cargo Capacity
The 718 Cayman has a much larger trunk than the RC F (14.9 vs. 9.9 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 RC F 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 RC F doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.
Ergonomics
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 RC F does not have an oil pressure gauge.
To improve rear visibility by keeping the rear window clear, the 718 Cayman offers an optional rear wiper. The RC F doesn’t offer a rear wiper.
To help drivers see further while navigating curves, the 718 Cayman has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The RC F doesn’t offer cornering lights.
Model Availability
The Porsche 718 comes in coupe and convertible bodystyles; the Lexus RC F isn’t available as a convertible.
Economic Advantages
Insurance will cost less for the 718 Cayman owner. The Complete Car Cost Guide estimates that insurance for the 718 Cayman will cost $5685 less than the RC F over a five-year period.
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 59.8% to 62.29% of its original price after five years, while the RC F only retains 53.66% to 53.85%.
