The 911 has standard Warn and Brake Assist, 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.

A passive infrared night vision system optional on the 911 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Challenger doesn’t offer a night vision system.

The 911’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Challenger doesn’t offer a lane departure warning system.

The 911 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Challenger only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the 911 and the Challenger 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 and available all wheel drive.

The 911’s corrosion warranty is 7 years and unlimited miles longer than the Challenger’s (12/unlimited vs. 5/60,000).

For smoother operation, better efficiency and fewer moving parts, the engines in the 911 have an overhead cam design, rather than the old pushrod design of some of the engines in the Challenger.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Dodge vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 70 more problems per 100 vehicles, Dodge is ranked 28th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Porsche vehicles are more reliable than Dodge vehicles. Consumer Reports ranks Porsche 10 places higher in reliability than Dodge.

In heavy traffic or at stoplights the 911’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.

The 911 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 911’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 911 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 911 stops much shorter than the Challenger:

For better traction and acceleration, the 911 has larger standard rear tires than the Challenger (295/35R20 vs. 235/55R18).

The 911’s standard 235/40R19 front and 295/35R20 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Challenger SXT’s standard 55 series tires. The 911’s optional 305/30R21 rear tires have a lower 30 series profile than the Challenger Widebody’s 35 series tires.

For better ride, handling and brake cooling the 911 has standard 19-inch front and 20-inch rear wheels. Smaller 18-inch wheels are standard on the Challenger SXT. The 911’s optional 21-inch rear wheels are larger than the 20-inch wheels optional on the Challenger.

The 911 S offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Challenger doesn’t offer an active sway bar system.

For better maneuverability, the 911’s turning circle is .6 feet tighter than the Challenger SXT/GT/R/T’s (36.8 feet vs. 37.4 feet). The 911’s turning circle is 1.9 feet tighter than the Challenger Widebody’s (36.8 feet vs. 38.7 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 500 to 850 pounds less than the Dodge Challenger.

The 911 is 1 foot, 7.6 inches shorter than the Challenger, making the 911 easier to handle, maneuver and park in tight spaces.

The design of the Porsche 911 amounts to more than styling. The 911 has an aerodynamic coefficient of drag of .31 Cd. That is lower than the Challenger (.337 to .398). A more efficient exterior helps the 911 go faster and keeps the interior quieter. It also helps the 911 get better fuel mileage.

For excellent aerodynamics, the 911 has standard flush composite headlights. The Challenger has recessed headlights that spoil its aerodynamic shape and create extra drag.

The front grille of the 911 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Challenger doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the 911 S Coupe is quieter than the Challenger SRT Hellcat:

When three different drivers share the 911, the optional memory system makes it convenient for all three. Each keyless remote 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 911’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 911’s power parking brake sets with one touch and releases with one touch. The Challenger

The 911’s front and rear power windows all 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 911’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 Challenger’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To improve rear visibility by keeping the rear window clear, the 911 offers an optional rear wiper. The Challenger doesn’t offer a rear wiper.

To help drivers see further while navigating curves, the 911 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 911 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 911 has standard 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.
