Mercedes-Benz CLA250 vs Mercedes-Benz E300

What's the difference?

If you're after a hot hatch with a boot, you can't have one because it wouldn't be a hatch anymore.

What you can have is this little beast - the new, second-generation Mercedes-AMG CLA 45 S, a small coupe-style sedan sharing its high-performance DNA with the hot as bubbling lava A 45 S hatch.

Packing 300kW – that's just over 420hp – and 500Nm its 2.0-litre engine is claimed to be the most powerful series production turbo four ever made.

And Australian deliveries are scheduled for early 2020, with a likely price tag in the mid-$90k bracket.

Mercedes-AMG invited us to the car's global launch in Madrid, Spain, where we got behind the wheel on road and track.

It might not be as tribal as Ford vs Holden, but there’s a rivalry between BMW and Mercedes-Benz that occasionally becomes more obvious - the launch of the new Mercedes E-Class only months after the BMW 5 Series being one of those times.

But Mercedes has done something different. Instead of multiple variants and electric cars under the E-Class banner, Australia gets just one, the E300.

Is it enough to tackle the big Bavarian sedan in the sales race? We attended the Australian launch just north of Melbourne to find out.
