BMW M440I vs Mercedes-Benz Eqe300

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.  

The EQE53 SUV is Mercedes-AMG's first fully-electric SUV.

That means it doesn't have a thundering V8 like a lot of its petrol-powered AMG siblings, but what it lacks in ear-splitting noise it makes up for in colossal but quietly delivered shove.

Which, when you have a sleeping child in the back, is exactly what you might need, because this after all is a family review and we're testing how good this silent beast of an SUV is when it comes to family duties.
