The 911 (except GT3) 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, available all wheel drive, blind spot warning systems and rear cross-path warning.

Warranty

The 911 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Challenger’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The 911’s corrosion warranty is 7 years longer than the Challenger’s (12 vs. 5 years).

Reliability

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’ 2022 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 above average in long-term dependability. With 30 more problems per 100 vehicles in the first three years of ownership, Dodge is rated lower.

	911	Challenger
Zero to 60 MPH	2.7 sec	3.7 sec
Quarter Mile	10.8 sec	11.7 sec
Speed in 1/4 Mile	127.9 MPH	125.4 MPH

In a Motor Trend race course test, the Porsche 911 S Coupe was clocked 7.18 seconds faster than the Dodge SRT Hellcat Redeye (95.52 sec. vs. 102.7 sec.).

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The Challenger doesn’t offer a boxer engine configuration.

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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Challenger doesn’t offer an automatic engine start/stop system.

The 911’s optional fuel tank has 5.2 gallons more fuel capacity than the Challenger (23.7 vs. 18.5 gallons).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Porsche 911 higher (3 to 5 out of 10) than the Dodge Challenger (1 to 3). This means the 911 produces up to 39 pounds less smog-producing pollutants than the Challenger every 15,000 miles.

Transmission

The 911 offers a standard 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.

Brakes and Stopping

For better stopping power the 911’s brake rotors are larger than those on the Challenger:

	911	911 Turbo S/Sport Classic	Challenger SXT	Challenger Hellcat/Redeye
Front Rotors	13 inches	16.5 inches	12.6 inches	15.7 inches
Rear Rotors	13 inches	15.4 inches	12.6 inches	13.8 inches

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:

	911	Challenger
70 to 0 MPH	133 feet	176 feet	Car and Driver
60 to 0 MPH	93 feet	109 feet	Motor Trend

Tires and Wheels

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

The 911 Dakar’s standard 245/45R19 front and 295/40R20 rear tires provide better handling because they have a lower 45 series front and 40 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.

Suspension and Handling

The 911 (except Base/GT3) 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.

The 911 GT3 handles at 1.16 G’s, while the Challenger SXT pulls only .86 G’s of cornering force in a Car and Driver skidpad test.

The 911 GT3 executes Motor Trend’s “Figure Eight” maneuver 3.2 seconds quicker than the Challenger Scat Pack (22.3 seconds @ .95 average G’s vs. 25.5 seconds @ .81 average G’s).

For better maneuverability, the 911’s turning circle is tighter than the Challenger’s:

	911	Challenger
Coupe	34.1 feet	37.8 feet
AWD Coupe	34.1 feet	37.8 feet

Chassis

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 700 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 offers aerodynamic coefficients of drag from .31 to .33 Cd (depending on bodystyle and options). 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.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Dodge. J.D. Power ranks Porsche third in service department satisfaction. With a 39% lower rating, Dodge is ranked 21st.

Ergonomics

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

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 (except Cabriolet/GT3) offers an optional rear wiper. The Challenger doesn’t offer a rear wiper.

The 911’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Challenger’s standard projector halogen headlights and light instantly. LED lights also last over twenty times longer than halogen. The 911’s LED headlights produce a white, bright light using less electricity than the Challenger’s optional xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

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’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. The Challenger has an automatic rear view mirror, but its side mirrors don’t dim.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Challenger doesn’t offer an automated parking system.

Model Availability

The Porsche 911 comes in coupe and convertible bodystyles; the Dodge Challenger isn’t available as a convertible.
