BMW 320d vs Audi A7

What's the difference?

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.

Audi is known as a design-led brand, and arguably no model in the line-up embodies that ethos more than the Audi A7 Sportback.

This all-new version of Audi's largest swoopy five-door hatchback takes the concept of the original first-generation version and, rather than reinventing the idea, reimagines it with a more modern and even more style-focused look, inside and out.

And it's a very convincing execution, indeed.
