The 718 Cayman Auto offers optional Porsche Active Safety, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Challenger offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.

The 718 Cayman has standard ParkAssist to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The Challenger doesn’t offer a front parking aid.

Both the 718 Cayman and the Challenger have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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 and available blind spot warning systems.

Regenerative brakes improve the 718 Cayman’s fuel efficiency by converting inertia back into energy instead of wasting it. The Challenger 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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Challenger doesn’t offer an automatic engine start/stop system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Porsche 718 Cayman higher (3 out of 10) than the Dodge Challenger (1 to 3). This means the 718 Cayman produces up to 22.5 pounds less smog-producing pollutants than the Challenger every 15,000 miles.

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 Challenger doesn’t offer an SMG.

The 718 Cayman’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the Challenger SXT are solid, not vented.

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 Challenger doesn’t offer ceramic brake rotors.

The 718 Cayman stops much shorter than the Challenger:

For better traction and acceleration, the 718 Cayman has larger standard rear tires than the Challenger (265/45R18 vs. 235/55R18).

The 718 Cayman’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Challenger SXT’s standard 55 series tires. The 718 Cayman’s optional 305/30R20 rear tires have a lower 30 series profile than the Challenger Widebody’s 35 series tires.

The 718 Cayman S handles at 1.04 G’s, while the Challenger SXT pulls only .86 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 Challenger Scat Pack (23.7 seconds @ .89 average G’s vs. 25.5 seconds @ .81 average G’s).

For better maneuverability, the 718 Cayman’s turning circle is 1.3 feet tighter than the Challenger SXT/GT/R/T’s (36.1 feet vs. 37.4 feet). The 718 Cayman’s turning circle is 2.6 feet tighter than the Challenger SRT Hellcat’s (36.1 feet vs. 38.7 feet).

The Porsche 718 Cayman may be more efficient, handle and accelerate better because it weighs about 900 to 1450 pounds less than the Dodge Challenger.

The 718 Cayman is 2 feet, 1.1 inches shorter than the Challenger, making the 718 Cayman easier to handle, maneuver and park in tight spaces.

The 718 Cayman is 5.8 inches narrower on average than the Challenger, making the 718 Cayman easier to handle and maneuver in traffic.

The design of the Porsche 718 Cayman amounts to more than styling. The 718 Cayman offers aerodynamic coefficients of drag from .3 to .31 Cd (depending on bodystyle and options). That is significantly lower than the Challenger (.337 to .398). A more efficient exterior helps the 718 Cayman go faster and keeps the interior quieter. It also helps the 718 Cayman get better fuel mileage.

For excellent aerodynamics, the 718 Cayman has standard flush composite headlights. The Challenger has recessed headlights that spoil its aerodynamic shape and create extra drag.

As tested by Car and Driver, the interior of the 718 Cayman is quieter than the Challenger SRT Hellcat:

To make loading groceries and cargo easier when your hands are full, just holding your hand near the emblem on the trunk can open the 718 Cayman’s available trunk, leaving your hands completely free. The Challenger doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

When two different drivers share the 718 Cayman, the optional memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position, outside mirror angle and climate settings. The Challenger doesn’t offer a memory system.

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 Challenger doesn’t offer an easy entry system.

The 718 Cayman’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Challenger’s power windows’ switches have to be held the entire time to close them fully.

The 718 Cayman has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Challenger doesn’t offer a locking fuel door.

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

To help drivers see further while navigating curves, the 718 Cayman offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Challenger doesn’t offer cornering lights.

When the 718 Cayman with available tilt-down mirrors is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Challenger’s mirror doesn’t automatically adjust for backing.

The 718 Cayman offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Challenger has an automatic rear view mirror, but its side mirrors don’t dim.
