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

The A5 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The 4 Series Coupe doesn’t offer an SMG or a conventional manual transmission.

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 Coupe’s standard 45 series tires. The A5 Premium Plus/Prestige’s optional tires have a lower 35 series profile than the 4 Series Coupe’s optional 40 series front tires.

Heated windshield washer nozzles are standard on the A5 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The 4 Series Coupe doesn’t offer heated windshield washer nozzles.
