Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Audi S4 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 Gran Coupe doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Audi S4 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 4 Series Gran Coupe doesn’t offer height-adjustable seat belts.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the S4. But it costs extra on the 4 Series Gran Coupe.

Both the S4 and the 4 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available crash mitigating brakes, blind spot warning systems and rearview cameras.

Reliability Comparison

J.D. Power and Associates’ 2015 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than BMW vehicles. J.D. Power ranks Audi 14th in reliability, above the industry average. With 8 more problems per 100 vehicles, BMW is ranked 18th.

The S4’s 3.0 supercharged V6 produces 33 more horsepower (333 vs. 300) and 25 lbs.-ft. more torque (325 vs. 300) than the 435i Gran Coupe’s standard 3.0 turbo 6 cyl.

Tires and Wheels Comparison

For better traction, the S4 has larger standard tires than the 4 Series Gran Coupe (245/40R18 vs. 225/50R17). The S4’s optional tires are larger than the largest tires available on the 4 Series Gran Coupe (255/35R19 vs. 225/45R18).

The S4’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 428i Gran Coupe’s standard 50 series tires. The S4’s optional tires have a lower 35 series profile than the 4 Series Gran Coupe’s optional 40 series front tires.

For better ride, handling and brake cooling the S4 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 428i Gran Coupe.

The S4 has .4 inches more rear headroom and 1.5 inches more rear legroom than the 4 Series Gran Coupe.

Cargo Capacity Comparison

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the S4 offers cargo security. The 4 Series Gran Coupe’s hatchback body style defeats cargo security.

Ergonomics Comparison

Heated windshield washer nozzles are standard on the S4 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 4 Series Gran Coupe doesn’t offer heated windshield washer nozzles.

Economic Advantages Comparison

The S4 will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the S4 will retain 50.15% to 50.75% of its original price after five years, while the 4 Series Gran Coupe only retains 43.47% to 46.02%.

Recommendations Comparison

The S4 was selected by Automobile Magazine as their 2010 Car of the Year. The 4 Series has never been chosen.
