Safety

For enhanced safety, the front and rear seat shoulder belts of the Audi S5 Sportback 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 3 Series Gran Turismo doesn’t offer pretensioners for the rear seat belts.

The S5 Sportback’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 3 Series Gran Turismo doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Audi S5 Sportback 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 3 Series Gran Turismo doesn’t offer height-adjustable seat belts.

The S5 Sportback has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 3 Series Gran Turismo doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the S5 Sportback and the 3 Series Gran Turismo have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, all-wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the S5 Sportback the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The 3 Series Gran Turismo has not been tested, yet.

The S5 Sportback’s 3.0 turbo V6 produces 27 more horsepower (349 vs. 322) and 39 lbs.-ft. more torque (369 vs. 330) than the 340i Gran Turismo’s standard 3.0 turbo 6 cyl.

Tires and Wheels

For better traction, the S5 Sportback has larger standard tires than the 3 Series Gran Turismo (245/40R18 vs. 225/45R18). The S5 Sportback’s optional tires are larger than the largest tires available on the 3 Series Gran Turismo (265/30R20 vs. 225/45R19).

The S5 Sportback’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 3 Series Gran Turismo’s standard 45 series tires. The S5 Sportback’s optional tires have a lower 30 series profile than the 340i Gran Turismo’s optional 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the S5 Sportback offers optional 20-inch wheels. The 3 Series Gran Turismo’s largest wheels are only 19-inches.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the S5 Sportback is 1.8 inches wider in the front than on the 3 Series Gran Turismo.

The S5 Sportback Prestige handles at .93 G’s, while the 330i Gran Turismo pulls only .86 G’s of cornering force in a Motor Trend skidpad test.

The S5 Sportback Prestige executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the 330i Gran Turismo (25 seconds @ .76 average G’s vs. 26.6 seconds @ .68 average G’s).

For better maneuverability, the S5 Sportback’s turning circle is 2 feet tighter than the 3 Series Gran Turismo’s (38.4 feet vs. 40.4 feet).

Chassis

The design of the Audi S5 Sportback amounts to more than styling. The S5 Sportback has an aerodynamic coefficient of drag of .29 Cd. That is lower than the 3 Series Gran Turismo (.29 to .3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the S5 Sportback get better fuel mileage.

Passenger Space

The S5 Sportback has .5 inches more front shoulder room and .4 inches more rear shoulder room than the 3 Series Gran Turismo.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than BMW. J.D. Power ranks Audi third in service department satisfaction. With a 14% lower rating, BMW is ranked 8th.

Ergonomics

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the S5 Sportback has standard extendable sun visors. The 3 Series Gran Turismo doesn’t offer extendable visors.

Optional air-conditioned seats in the S5 Sportback keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The 3 Series Gran Turismo doesn’t offer air-conditioned seats.

Economic Advantages

The S5 Sportback will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S5 Sportback will retain 51.38% to 51.57% of its original price after five years, while the 3 Series Gran Turismo only retains 46.56% to 47.51%.
