BMW 4 Series vs Mercedes-Benz CLA250

What's the difference?

Without a whole lot of fanfare BMW has slipped yet another model into its Australian line-up.

Sitting alongside existing coupe and convertible variants, the new 4 Series Gran Coupe follows the template established by the previous gen version. 

A sports luxury four-door with a sleek, fastback twist, it provides a more adventurous alternative to its close 3 Series cousin. 

Offered in three grades, this is the M440i xDrive, the 3.0-litre, six-cylinder, all-wheel drive 4 Series Gran Coupe flagship. 

It competes with premium all-wheel drive four-doors like Audi’s S5 Sportback, the Jaguar XF P300 R-Dynamic HSE, and the Mercedes-AMG C 43.  

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.
