Both the Charger SRT and the S4 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

The Dodge Charger SRT weighs 678 pounds more than the Audi S4. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.


Dodge’s powertrain warranty covers the Charger SRT 1 year and 10,000 miles longer than Audi covers the S4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the S4 ends after only 4 years or 50,000 miles.

There are almost 8 times as many Dodge dealers as there are Audi dealers, which makes it much easier should you ever need service under the Charger SRT’s warranty.


The Dodge Charger SRT’s engine uses a cast iron block for durability, while the S4’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

To reliably power the ignition and other systems and to recharge the battery, the Charger SRT has a standard 220-amp alternator. The S4’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Dodge vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Dodge 19th in initial quality. With 7 more problems per 100 vehicles, Audi is ranked 25th.


The Charger SRT’s 6.2 supercharged V8 produces 358 more horsepower (707 vs. 349) and 281 lbs.-ft. more torque (650 vs. 369) than the S4’s 3.0 turbo V6.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Charger SRT 392’s fuel efficiency. The S4 doesn’t offer a system that can shut down part of the engine.

The Charger SRT has 3.2 gallons more fuel capacity than the S4 (18.5 vs. 15.3 gallons), for longer range between fill-ups.

The Charger SRT has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The S4 doesn’t offer a cap-less fueling system.

Brakes and Stopping

For better stopping power the Charger SRT’s brake rotors are larger than those on the S4:

Front Rotors

15.4 inches

13.8 inches

Rear Rotors

13.8 inches

13 inches

Tires and Wheels

For better traction, the Charger SRT has larger tires than the S4 (275/40R20 vs. 245/40R18).

For better ride, handling and brake cooling the Charger SRT has standard 20-inch wheels. Smaller 18-inch wheels are standard on the S4. The S4’s largest wheels are only 19-inches.

The Charger SRT 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 S4; 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 Charger SRT’s wheelbase is 9.2 inches longer than on the S4 (120.4 inches vs. 111.2 inches).

For better handling and stability, the track (width between the wheels) on the Charger SRT is 2.4 inches wider in the front and 2.8 inches wider in the rear than on the S4.


To almost totally eliminate engine vibration in the passenger area, the Charger SRT has liquid-filled engine mounts. The liquid helps further dampen engine harshness. The S4 uses conventional solid rubber engine mounts.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Charger SRT a Large car, while the S4 is rated a Compact.

The Charger SRT has 12.7 cubic feet more passenger volume than the S4 (104.7 vs. 92).

The Charger SRT has .5 inches more front legroom, 3.6 inches more front shoulder room, 4.4 inches more rear legroom and 3.4 inches more rear shoulder room than the S4.

Cargo Capacity

The Charger SRT has a much larger trunk than the S4 (16.5 vs. 13 cubic feet).


The Charger SRT 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 S4 doesn’t offer a remote starting system.

The Charger SRT’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The S4 doesn’t offer an easy entry system.

The Charger SRT’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 S4 does not have an oil pressure gauge.

On a hot day the Charger SRT’s driver can lower the front windows from a distance using the keyless remote. The driver of the S4 can’t use the remote to operate the windows.

When the Charger SRT is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The S4’s mirrors don’t automatically adjust for backing.

The Charger SRT 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 S4.


The Dodge Charger outsold the Audi A4/S4 by over two to one during 2018.
