Both the Shelby GT350 and the S5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.


Ford’s powertrain warranty covers the Shelby GT350 1 year and 10,000 miles longer than Audi covers the S5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the S5 ends after only 4 years or 50,000 miles.

There are almost 10 times as many Ford dealers as there are Audi dealers, which makes it much easier should you ever need service under the Shelby GT350’s warranty.


J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Ford vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Ford fifth in initial quality, above the industry average. With 24 more problems per 100 vehicles, Audi is ranked 25th, below the industry average.


The Shelby GT350’s 5.2 DOHC V8 produces 177 more horsepower (526 vs. 349) and 60 lbs.-ft. more torque (429 vs. 369) than the S5’s 3.0 turbo V6.

Fuel Economy and Range

The Shelby GT350 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 S5 doesn’t offer a cap-less fueling system.


The Shelby GT350 offers a manual transmission for better acceleration, control and fuel economy. The S5 doesn’t offer a manual transmission.

The Shelby GT350’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The S5 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Shelby GT350’s brake rotors are larger than those on the S5:

Tires and Wheels

For better traction, the Shelby GT350 has larger standard tires than the S5 (F:295/35R19 & R:305/35R19 vs. 245/40R18). The Shelby GT350R Coupe’s tires are larger than the largest tires available on the S5 (F:305/30R19 & R:315/30R19 vs. 265/30R20).

The Shelby GT350 Coupe’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 S5’s standard 40 series tires.

For better ride, handling and brake cooling the Shelby GT350 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the S5.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the Shelby GT350 is .8 inches wider in the front and 2 inches wider in the rear than on the S5.

The Shelby GT350R Coupe handles at 1.10 G’s, while the S5 Prestige Coupe pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

Passenger Space

The Shelby GT350 has .5 cubic feet more passenger volume than the S5 Coupe (84.5 vs. 84).

The Shelby GT350R Coupe has 3.2 inches more front legroom and 1 inch more front shoulder room than the S5 Coupe.

Cargo Capacity

The Shelby GT350R Coupe has a much larger trunk than the S5 Coupe (13.5 vs. 11.6 cubic feet).


The Shelby GT350’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 S5 does not have an oil pressure gauge.

Economic Advantages

The Shelby GT350 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Shelby GT350 will retain 62.91% to 64.58% of its original price after five years, while the S5 only retains 48.53% to 51.66%.


The Shelby GT350 was chosen as one of Car and Driver’s “Top Ten” for 8 of the last 15 years. The S5 has never been a Car and Driver “Top Ten” pick.

The Shelby GT350 was chosen as one of Automobile Magazine’s “All Stars” for 4 of the last 24 years. The S5 has never been an “All Star.”
