Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Audi A5 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 Convertible doesn’t offer pretensioners for the rear seat belts.

The A5’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 Convertible doesn’t offer pre-crash pretensioners.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A5. But it costs extra on the 4 Series Convertible.

To help make backing safer, the A5 Premium Plus/Prestige’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 Convertible doesn’t offer a cross-path warning system.

Both the A5 and the 4 Series Convertible 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, blind spot warning systems and around view monitors.

Reliability Comparison

The Audi A5’s engine uses a cast iron block for durability, while the 4 Series Convertible’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

J.D. Power and Associates’ 2016 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 11th in reliability, above the industry average. With 8 more problems per 100 vehicles, BMW is ranked 14th.

From surveys of all its subscribers, Consumer Reports’ April 2017 Auto Issue reports that Audi vehicles are more reliable than BMW vehicles. Consumer Reports ranks Audi fourth in reliability. BMW is ranked 8th.

Engine Comparison

The A5’s 2.0 turbo 4 cyl. produces 4 more horsepower (252 vs. 248) and 15 lbs.-ft. more torque (273 vs. 258) than the 430i Convertible’s standard 2.0 turbo 4 cyl.

Fuel Economy and Range Comparison

On the EPA test cycle the A5 Auto gets better fuel mileage than the 430i Convertible xDrive (24 city/34 hwy vs. 22 city/

32 hwy).

To lower fuel costs and make buying fuel easier, the Audi A5 uses regular unleaded gasoline (premium recommended for maximum performance). The 4 Series Convertible requires premium, which can cost 20 to 55 cents more per gallon.

Brakes and Stopping Comparison

For better stopping power the A5’s standard brake rotors are larger than those on the 4 Series Convertible:

 

A5

4 Series Convertible

Front Rotors

13.3 inches

13 inches

Rear Rotors

13 inches

11.8 inches

Tires and Wheels Comparison

For better traction, the A5 has larger standard tires than the 4 Series Convertible (245/40R18 vs. 225/45R18).

The A5’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 Convertible’s standard 45 series tires. The A5’s optional tires have a lower 35 series profile than the 4 Series Convertible’s optional 40 series front tires.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the A5 is 1.7 inches wider in the front than on the 4 Series Convertible.

Chassis Comparison

The Audi A5 may be more efficient, handle and accelerate better because it weighs about 350 to 500 pounds less than the BMW 4 Series Convertible.

Cargo Capacity Comparison

The A5’s standard folding rear seats are split to accommodate bulky cargo. The 4 Series Convertible’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the A5 offers cargo security. The 4 Series Convertible’s non-lockable folding seat defeats cargo security.

Ergonomics Comparison

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A5 has standard extendable sun visors. The 4 Series Convertible doesn’t offer extendable visors.

Both the A5 and the 4 Series Convertible offer optional heated front seats. The A5 Premium Plus/Prestige also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the 4 Series Convertible.

Optional air-conditioned seats in the A5 Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The 4 Series Convertible doesn’t offer air-conditioned seats.
