The Audi A4 has just turned 25 years old, with the Ingolstadt-based firm saying “demand is unabated” after two-and-a-half decades of production.

So, how many examples have been produced in total? Well, the German brand says more than 7,5 million units have been built over the past 25 years, making the A4 Audi's most successful model of all time.

Indeed, with 344 586 units (now in the fifth generation) sold in 2018, the A4 is still the company’s most popular model globally, with every fifth Audi delivered worldwide coming from this model line.

The A4 went into production in 1994 as the successor to the Audi 80 series. In 1995, more than 272 052 units left the production line.

“For a quarter of a century now, the Audi A4 has symbolised the Four Rings like no other model. It stands for cutting‑edge technology in the premium mid‑range, as well as for innovative production technologies at the highest level,” said Albert Mayer, plant director at Audi’s factory in Ingolstadt.

“The Audi A4 is a key pillar of the Ingolstadt plant in particular. Our employees’ tireless commitment and passion for our brand have been and continue to be the driving force behind the impressive success story of the A4.”

Audi also produces the A4 in Neckarsulm in Germany, as well as in Changchun (China) and Aurangabad (India).

In South Africa, some 403 units from the A4 range were sold over the first four months of 2019, 17 of which came in the form of the RS4 Avant...
