2019 Audi A4 vs BMW 3 Series

What's the difference?

Audi's A4 is one of those cars that everybody likes. Despite wearing a German badge, it doesn't feel the need to bellow about itself. If anything, the A4 is so subtle you have to check it's not either its smaller sibling the A3 or its larger one, the A6.

In 2019, the A4 has a bit of a blue on its hands - the new BMW 3 Series is a belter of a car. The rivalry is now freshly-fired, with the 3 lifting its game in every single area, including the interior. And the C-Class is still going strong.

The A4 isn't a whole new car, though, it's the mildest of mild refreshes of a model we've had here for just over three years.

Over 44 years BMW has produced more than 15 million examples of the 3 Series. That's roughly one every minute and a half... for over four decades.

And the latest, seventh-generation version of what the famous German maker defines as the "heart and soul" of its brand has landed in Australia.

The new '3' is longer and wider. It's also claimed to be slicker aerodynamically, up to 55 kilos lighter, more fuel efficient, and faster.

And it'll need every advantage it can muster to take a chunk out of its arch rival, the all-conquering Mercedes-Benz C-Class.
