For enhanced safety, the front and rear seat shoulder belts of the Audi RS 5 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Porsche 911 doesn’t offer pretensioners for its rear seat belts.

The RS 5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 911 doesn’t offer pre-crash pretensioners.

The Audi RS 5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The 911 doesn’t offer knee airbags.

The RS 5 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 911 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the RS 5. But it costs extra on the 911.

The RS 5’s standard 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. A lane departure warning system costs extra on the 911.

Both the RS 5 and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

There are over 54 percent more Audi dealers than there are Porsche dealers, which makes it much easier should you ever need service under the RS 5’s warranty.

Engine

The RS 5’s 2.9 turbo V6 produces 65 more horsepower (444 vs. 379) and 111 lbs.-ft. more torque (442 vs. 331) than the 911’s standard 3.0 turbo 6-cylinder. The RS 5’s 2.9 turbo V6 produces 1 more horsepower (444 vs. 443) and 52 lbs.-ft. more torque (442 vs. 390) than the 911 S’ standard 3.0 turbo 6-cylinder. The RS 5’s 2.9 turbo V6 produces 22 lbs.-ft. more torque (442 vs. 420) than the 911 GTS/Dakar’s standard 3.0 turbo 6-cylinder.

As tested in Motor Trend the Audi RS 5 is faster than the Porsche 911 3.0 turbo 6-cylinder (automatics tested):

	RS 5	911
Zero to 60 MPH	3.5 sec	3.9 sec
Quarter Mile	12 sec	12.2 sec

Fuel Economy and Range

On the EPA test cycle the RS 5 gets better mileage than the 911 Coupe:

		3.7 turbo flat-6	14 city/21 hwy
		3.7 turbo flat-6	14 city/20 hwy
		3.0 turbo flat-6	18 city/24 hwy

Regenerative brakes improve the RS 5’s fuel efficiency by converting inertia back into energy instead of wasting it. The 911 doesn’t offer a regenerative braking system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi RS 5 higher (5 out of 10) than the Porsche 911 (3 to 5). This means the RS 5 produces up to 16.5 pounds less smog-producing pollutants than the 911 every 15,000 miles.

Brakes and Stopping

For better stopping power the RS 5’s standard brake rotors are larger than those on the 911:

	RS 5	911
Front Rotors	14.8 inches	13 inches

Tires and Wheels

For better traction, the RS 5 has larger standard tires than the 911 (265/35R19 vs. 235/40R19).

The RS 5’s standard tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires.

The RS 5 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 911; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For a smoother ride and more stable handling, the RS 5’s wheelbase is 12.4 inches longer than on the 911 (108.9 inches vs. 96.5 inches).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the RS 5 a Subcompact car, while the 911 Coupe is rated a Minicompact.

The RS 5 has 11 cubic feet more passenger volume than the 911 (84 vs. 73).

The RS 5 has 2.7 inches more front shoulder room, 3.6 inches more rear headroom, 5.5 inches more rear legroom and 2.8 inches more rear shoulder room than the 911.

Cargo Capacity

The RS 5 has a much larger trunk than the 911 Coupe with its rear seat up (10.9 vs. 4.6 cubic feet).

Pulling a handle automatically lowers the RS 5’s rear seats, to make changing between passengers and cargo easier. The 911 doesn’t offer automatic folding seats.

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the RS 5 offers cargo security. The 911’s non-lockable folding seat defeats cargo security.

To make loading and unloading groceries and cargo easier when your hands are full, the RS 5’s power trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The RS 5’s power trunk can also be opened or closed by pressing a button. The 911 doesn’t offer a power or hands-free opening trunk.

Ergonomics

The RS 5 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 911 doesn’t offer a remote starting system.

The RS 5 offers an optional heads-up display that projects speed, warning, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 911 doesn’t offer a heads-up display.

If the windows are left open on the RS 5 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

The RS 5 has a standard Audi Advanced Key that allows you to unlock the doors from either outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. The 911 GT3 doesn’t offer Comfort Access.

Heated windshield washer nozzles are standard on the RS 5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 911 doesn’t offer heated windshield washer nozzles.

Laser headlights, standard on the RS 5, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the 911’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RS 5 has standard headlight washers to keep headlight output high. The 911 doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the RS 5 has standard extendable sun visors. The 911 doesn’t offer extendable visors.

The RS 5 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the 911.

The RS 5 has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the 911.

For greater rear passenger comfort, the RS 5 has standard rear a/c vents to keep rear occupants more comfortable. The 911 doesn’t offer rear vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi RS 5 has a standard wireless phone charging system (Qi) in the center console. The 911 doesn’t offer wireless personal charging.

Economic Advantages

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi RS 5 will be $10533 to $1778503 less than for the Porsche 911.

Recommendations

The Audi A5/S5/RS 5 outsold the Porsche 911 by over two to one during 2023.
