Safety Comparison

The Mustang Premium’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A5 doesn’t offer a driver alert monitor.

Both the Mustang and the A5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty Comparison

Ford’s powertrain warranty covers the Mustang 1 year and 10,000 miles longer than Audi covers the A5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the A5 ends after only 4 years or 50,000 miles.

There are almost 11 times as many Ford dealers as there are Audi dealers, which makes it much easier should you ever need service under the Mustang’s warranty.

Reliability Comparison

J.D. Power and Associates’ 2017 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 fourth in initial quality, above the industry average. With 29 more problems per 100 vehicles, Audi is ranked 26th, below the industry average.

Engine Comparison

The Mustang’s standard 2.3 turbo 4 cyl. produces 58 more horsepower (310 vs. 252) and 77 lbs.-ft. more torque (350 vs. 273) than the A5’s 2.0 turbo 4 cyl. The Mustang GT’s standard 5.0 DOHC V8 produces 208 more horsepower (460 vs. 252) and 147 lbs.-ft. more torque (420 vs. 273) than the A5’s 2.0 turbo 4 cyl.

Fuel Economy and Range Comparison

The Mustang 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 A5 doesn’t offer a cap-less fueling system.

For better maneuverability, the Mustang’s turning circle is 1.2 feet tighter than the A5’s (36.5 feet vs. 37.7 feet).

Chassis Comparison

The front grille of the Mustang (except Performance Pack) uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The A5 doesn’t offer active grille shutters.
