Compare the2024 Ford MustangVS 2024 Audi RS 3

For enhanced safety, the front and rear seat shoulder belts of the Ford Mustang have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Audi RS 3 doesn’t offer pretensioners for its rear seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Mustang are reminded to check the back seat. The RS 3 doesn’t offer a back seat reminder.

The Mustang has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the RS 3’s blind spot costs extra.

To help make backing out of a parking space safer, the Mustang has standard Cross Traffic Alert and Cross Traffic Braking automatically engages the brakes to help avoid a collision. Audi charges extra for Rear Cross-Traffic Assist on the RS 3.

The Mustang’s 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 RS 3 doesn’t offer a driver alert monitor.

Both the Mustang and the RS 3 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, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems and rearview cameras.

Ford’s powertrain warranty covers the Mustang 1 year and 10,000 miles longer than Audi covers the RS 3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the RS 3 ends after only 4 years or 50,000 miles.

The Mustang has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The RS 3 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

In heavy traffic or at stoplights the Mustang EcoBoost/GT (late availability)’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The RS 3 doesn’t offer an automatic engine start/stop system.

The Mustang Automatic 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 RS 3 doesn’t offer a remote starting system.

The Mustang’s optional Easy Entry and Exit glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The RS 3 doesn’t offer an easy entry system.
