The Charger SRT has standard Uconnect 9-1-1, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The S6 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Charger SRT and the S6 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, blind spot warning systems, rearview cameras and rear cross-path warning.


Dodge’s powertrain warranty covers the Charger SRT 1 year and 10,000 miles longer than Audi covers the S6. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the S6 ends after only 4 years or 50,000 miles.

There are over 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 S6’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 S6’s 210-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 257 more horsepower (707 vs. 450) and 244 lbs.-ft. more torque (650 vs. 406) than the S6’s 4.0 turbo V8.

Fuel Economy and Range

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 S6 doesn’t offer a cap-less fueling system.


An eight-speed automatic is standard on the Dodge Charger SRT, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the S6.

Brakes and Stopping

The Charger SRT stops shorter than the S6:

Motor Trend

Tires and Wheels

For better traction, the Charger SRT has larger tires than the S6 (275/40R20 vs. 255/35R20).

Suspension and Handling

For a smoother ride and more stable handling, the Charger SRT’s wheelbase is 5.6 inches longer than on the S6 (120.4 inches vs. 114.8 inches).

The Charger SRT Hellcat handles at .94 G’s, while the S6 pulls only .89 G’s of cornering force in a Motor Trend skidpad test.

The Charger SRT Hellcat executes Motor Trend’s “Figure Eight” maneuver quicker than the S6 (24.4 seconds @ .82 average G’s vs. 25 seconds @ .77 average G’s).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Charger SRT a Large car, while the S6 is rated a Mid-size.

The Charger SRT has 6.7 cubic feet more passenger volume than the S6 (104.7 vs. 98).

The Charger SRT has 1.4 inches more front headroom, .5 inches more front legroom, 2 inches more front shoulder room, 2.7 inches more rear legroom and 1.6 inches more rear shoulder room than the S6.

Cargo Capacity

The Charger SRT has a much larger trunk than the S6 (16.5 vs. 14.1 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 S6 doesn’t offer a remote starting 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 S6 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 S6 can’t use the remote to operate the windows.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Charger SRT has standard extendable sun visors. The S6 doesn’t offer extendable visors.

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 S6’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 S6.

Economic Advantages

The Charger SRT will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Charger SRT will retain 48.13% to 48.66% of its original price after five years, while the S6 only retains 45.87% to 46.02%.


The Dodge Charger outsold the Audi A6/S6 by over five to one during 2017.
