The Audi A4 carries over with minimal changes.

The Audi A4 45 S Line Premium trims gets a sport suspension as standard equipment and adds an optional Black Optic package for the 40 Premium trim, while the S4 and A4 Allroad carry over with minimal changes for 2022.

After an extensive facelift in 2020, the Audi A4 lineup returns for 2021 with a 12-volt hybrid system, increased horsepower for both versions of the 2L turbocharged engine, and more standard equipment including all-wheel drive.

The Audi A4 line gets several major changes for the 2020 model year. Exterior styling has been improved with a revised grille, less angular headlights and more pronounced wheel arches. The result is a smoother looking car that somehow looks more muscular as well. The interior has also been revised, with a new 10.1-inch touchscreen and Audi's MIB 3 infotainment suite. Audi claims that MIB 3 is up to ten times faster than the MIB 2 infotainment system on older models. LED headlights are also standard across the entire model line for 2020.

The Audi A4 has subtle updates to its front and rear fascias, but it is otherwise unchanged.

The Audi A4 adds few changes for 2018. Quattro models have been tuned to improve fuel efficiency. Premium Plus trims now include Side-Assist with Rear Cross Traffic Alert, Virtual Cockpit, and an 8.3-inch touch screen standard. Both Premium Plus and Prestige models now offer a "Black Optics" package that includes red brake calipers, a flat-bottomed steering wheel, red contrast stitching and high-gloss black wheels and side mirror.

The 2016 Audi A4 and S4 see only minor changes this year. A new set of 19" wheels are available on A4s with the S Line Competition Plus Package, while Audi Connect has been added to the Navigation Plus Package. Premium models get a new steering wheel while a new smart key is also available on Premium models.

Following a styling upgrade in 2014, the Audi A4 and S4 see no significant changes for 2015. Among the minor improvements, standard equipment on all A4s now includes a 60/40 split fold rear seat, headlight washer system and 3-zone climate control. New colors include Florett Silver metallic, Mythos Black metallic, Utopia Blue metallic, Tornado Gray metallic and Daytona Gray pearl.

The Audi A4 and S4 have redesigned styling for 2014. The grill is now more rounded hexagonal shape and the headlights have been revised, giving the car a slightly more modern look. The lower grill section utilizes sharper lines and angles than last year's car, accentuating the fog lights. Tail lights and the rear bumper have also been given subtle tweaks. The car's interior has also gotten some attention, with higher quality materials, more interior color options and simplified control interfaces. The A4 wagon is no longer available, having been replaced by the Allroad.

For 2013, the Audi A4 lineup gets some slight changes inside and out, including new interior and exterior color combinations. On the outside, the A4 gets a more slender headlight design, new "Singleframe" grille design and a strip of LED lights adjacent to the headlights with the xenon headlamp option. The taillight design is also new, with LED lamps and the hood and bumpers have been redesigned. Inside, the A4 gets a new high-gloss finish and 'alu-optic' soft keys for the MMI interface and the Audi Connect system is paired with MMI Navigation Plus. Also available (and standard on the S4) is a new 3-spoke flat-bottom steering wheel and alu-optic shift paddles on the automatic. The available adaptive front lighting system in the A4 and S4 gets a new static cornering lamp and there's a new Driver Assistance package that pairs adaptive cruise control and dynamic steering. Also, some A4 2.0T models are E85 compatible for 2013; all A4 models get electric power steering; and the S4 receives a new crown-gear center-differential. The A4 Avant wagon has also been discontinued for 2013, replaced by a new A4-based Allroad wagon model that's now a separate model with a more outdoorsy theme.

For 2012, the A4 and S4 return mostly unchanged. Most of the updates have to do with the availability of option packages. A revised S-Line package features added adaptive suspension and Drive Select control, giving the driver control over suspension settings at the touch of a button. New standard equipment includes daytime running lights, automatic headlights and rain sensing wipers.

High-tech changes make their way into the Audi A4 for 2011. Among them is the introduction of a new 8-speed automatic transmission in the turbocharged 2.0-liter A4 quattro sedan and wagon, replacing the old 6-speed. Audi claims the new, compact gearbox is smoother and returns improved fuel economy.

Now in its eighth generation, the Audi A4 sees few changes for 2010. A new S4 sedan and Avant wagon featuring a 3.0L supercharged V6 make their debut this year, available with either manual or 7-speed S-tronic transmissions. The 3.2L Quattro has been discontinued, and the cabriolet has been redesigned and is now part of the A5 line. Inside, high-quality materials abound, with plenty of leather and brushed aluminum, as one would expect from Audi. The interior is larger than the previous A4's, as is the trunk. An advanced multi-media interface is standard, as are six airbags. Other changes include available third generation MMI navigation, LED taillights on Premium Plus and Prestige models, and a new Quattro Sport Rear Differential and new wheels for the S4.

Now in its eighth generation, the Audi A4 is entirely redesigned for 2009. The new car is based on the underpinnings of the two-door A5 coupe and is thus wider and rides on a longer wheelbase than its predecessor. The body weighs 10% less than that of the car it replaces. Exterior styling is aggressive and in keeping with Audi's new company face. The front end features a larger grille and sculpted LED daytime running lights, while the sides are sculpted and scalloped. Inside, high-quality materials abound, with plenty of leather and brushed aluminum, as one would expect from Audi. The interior is larger than the previous A4's, as is the trunk. An advanced multi-media interface is standard, as are six airbags. A new, 265-hp 3.2-liter V6 replaces the 255-hp 3.2 V6, while a 211-hp 2.0L turbocharged 4-cylinder replaces the 200-hp unit of years past. The slick S4 cabriolet shares the exterior and interior refinement of the A4 and retains its 340-hp 4.2L V8. The all-new A4 starts at $32,700, while the S4 starts at $57,125.

The 2008 Audi A4 and S4 line carries forward with minimal changes. A number of S-Line visual features are now standard (bumpers, door sills, grille), as is a tire pressure monitor. The sedans and Avant wagons now have a standard sunroof as well. Models with the 3.2L engine now ride on 18-inch alloy wheels as opposed to 17s, and the front seats are heated. An iPod glovebox interface is a new option for the 2008 model year.

A redesigned line of Cabriolet models joins the Audi A4 family for 2007, more than a year behind the introduction of the latest redesigned A4 sedans and wagons. The Cabriolet gets a completely new look, and vastly improved noise insulation thanks to a standard acoustic top. The new line of direct-injection four-cylinder and V6 engines is now also installed in Cabriolets. On the A4 line, a new generation of the high-end Audi Symphony sound system is available for 2007.
