BMW 320d vs Mercedes-Benz C350 E

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.

They're doing it again! Actually they've been doing it again for a bit now. It’s Mercedes-Benz Australia and plug-in hybrid tech.

The Ross and Rachel, or Jim and Pam of the premium automotive world.

It's been a will they, won't they for a while, and in the past Mercedes has dipped its proverbial plug into the electrons a few times and gotten cold feet.

But now it says it’s all in. There are others, the GLA and GLC SUVs, plus there’s the new C63 performance car, but this one feels like a bit of an arrival.

Yeah, the C-Class is no longer the Mercedes-Benz in terms of sales, but it might be the best way to make the most of a bit of battery power.
