Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Audi S5 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 BMW 4 Series Coupe doesn’t offer pretensioners for the rear seat belts.

The S5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 4 Series Coupe doesn’t offer pre-crash pretensioners.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the S5. But it costs extra on the 4 Series Coupe.

To help make backing safer, the S5’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 4 Series Coupe doesn’t offer a cross-path warning system.

Both the S5 and the 4 Series Coupe 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, daytime running lights, rearview cameras, available lane departure warning systems and around view monitors.

The S5’s 3.0 turbo V6 produces 34 more horsepower (354 vs. 320) and 39 lbs.-ft. more torque (369 vs. 330) than the 440i Coupe’s standard 3.0 turbo 6 cyl.

Car and Driver

Tires and Wheels Comparison

For better traction, the S5 has larger standard tires than the 4 Series Coupe (245/40R18 vs. 225/45R18).

The S5’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 4 Series Coupe’s standard 45 series tires. The S5’s optional tires have a lower 35 series profile than the 440i Coupe’s optional 40 series front tires.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the S5 is 1.6 inches wider in the front than on the 4 Series Coupe.

The S5 Prestige Coupe handles at .94 G’s, while the 430i Coupe pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

Ergonomics Comparison

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the S5 has standard extendable sun visors. The 4 Series Coupe doesn’t offer extendable visors.

Optional air-conditioned seats in the S5 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The 4 Series Coupe doesn’t offer air-conditioned seats.
