To help make backing safer, the Charger SRT’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The S8 doesn’t offer a cross-path warning system.

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 S8 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 S8 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, available crash mitigating brakes and lane departure warning systems.


Dodge’s powertrain warranty covers the Charger SRT 1 year and 10,000 miles longer than Audi covers the S8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the S8 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 engines use a cast iron block for durability, while the S8’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 S8’s 190-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Charger SRT has a standard 730-amp battery. The S8’s 450-amp battery isn’t as powerful.

J.D. Power and Associates’ 2017 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 22nd in initial quality. With 9 more problems per 100 vehicles, Audi is ranked 26th.


The Charger SRT Hellcat’s standard 6.2 supercharged V8 produces 102 more horsepower (707 vs. 605) and 97 lbs.-ft. more torque (650 vs. 553) than the S8’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 S8 doesn’t offer a cap-less fueling system.

Suspension and Handling

For a smoother ride and more stable handling, the Charger SRT’s wheelbase is 2.5 inches longer than on the S8 (120.4 inches vs. 117.9 inches).

The Charger SRT Hellcat handles at .94 G’s, while the S8 Plus pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

The Charger SRT Hellcat executes Motor Trend’s “Figure Eight” maneuver quicker than the S8 (24.5 seconds @ .91 average G’s vs. 25.1 seconds @ .79 average G’s).

For better maneuverability, the Charger SRT’s turning circle is 1.4 feet tighter than the S8’s (39 feet vs. 40.4 feet).


The Dodge Charger SRT may be more efficient, handle and accelerate better because it weighs about 150 to 300 pounds less than the Audi S8.

Passenger Space

Because it has more passenger and cargo room, the Charger SRT is rated a Large car by the EPA, while the S8 is rated a Mid-size.

The Charger SRT has 2.8 cubic feet more passenger volume than the S8 (104.7 vs. 101.9).

The Charger SRT has 1.4 inches more front headroom, .4 inches more front legroom, .4 inches more front shoulder room, 1.4 inches more rear legroom and .1 inches more rear shoulder room than the S8.

Cargo Capacity

The Charger SRT has a much larger trunk than the S8 (16.5 vs. 14.2 cubic feet).

The Charger SRT’s standard rear seats fold to accommodate long and bulky cargo. The S8 doesn’t offer folding rear seats, only a ski pass-through.


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 S8 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 S8 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 S8 can’t use the remote to operate the windows.

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 S8.

Standard Uconnect for the Charger SRT allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The S8 doesn’t offer factory integrated smartphone program access.

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 S8 only retains 38.78%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Dodge Charger SRT will be $36160 to $52036 less than for the Audi S8.
