Audi’s A4 premium medium-sized battler has booked itself in for some plastic surgery to stay fresh for the model year 2019, incorporating some elements of Audi’s latest design language.

The 2019 Audi A4’s subtle improvements are hard to spot unless you’re a trainspotter. But, from the outside, the biggest clue is the sharper lower air intakes, with a U-shaped insert, which is highlighted in silver in S Line models. These also help channel incoming air past the wheels to minimise turbulence and improve the drag coefficient.

The bulk of the changes are reserved for the S Line model, with a new 3D grille pattern adorning the brand’s hallmark “single frame” grille. A new rear diffuser flanked by two trapezoidal exhaust outlets also distinguishes the car, in addition to new wheel designs ranging in diameter from 16 to 19 inches.

A new option now available is the S Line Competition package. It comes with Turbo Blue paint and an RS-inspired roof spoiler on the Avant wagon. The four-ringed motif that has been showing up on new Audis, such as the freshly-unveiled next-gen A1, also makes an appearance on the A4’s hindquarters. Other distinguishing elements of the Competition pack are selenite silver stone-chip guard and lower intake blade, Audi Sport 19-inch alloys, sport suspension, red brake calipers and LED headlights.

Inside, the S Line Competition scores carbon fibre trim, three-spoke steering wheel, black seats with leather inserts, or new Magma Red S sports seats, among other available colours.

In its home country, the 2019 Audi A4 sedan and Avant will commence sales in the third quarter of this year, so it will hit Australian shores sometime thereafter. By then, a new BMW 3 Series will have arrived and the Mercedes-Benz C-Class will not be far off its mid-cycle nip and tuck. What do you think of the new Audi A4?

Eccentric car nut, just as enthused by roasting an egg on the air cleaner of an old Hemi as I am hunting the horizon in a space age electric supercar. Dropped on head at young age, which gave me a meticulous automotive obsesseion for obscure facts.
