Mazda 6 vs BMW M5

What's the difference?

Has it really been 20 years since the humble Mazda6 station wagon hit our roads? You betcha, but I was more shocked that I remembered when it did!

I have a sudden flashback of questionable fashion choices, glittery butterfly hair clips and how Skipper was making a play at being the coolest 'Barbie' (she wasn't).

I've always had a soft spot for wagons, they are the forgotten heroes for family hauling. It's hard not to glide over them when the market is dominated by SUVs but if you happen to remember they still exist (albeit, barely) you might remember why they were popular back in the day.

Being a 20th Anniversary Edition means there are some nods to the past in this model but unlike the low-slung jeans of my youth, they're stylishly done. With some luxuriously-appointed rivals to contend with, like the Skoda Octavia and Volkswagen Passat, does it offer enough to be considered by a modern family?

My little family of three has been in it all week to find out for you!

Balancing luxury car comfort, hot hatch agility and supercar speed is no easy task, yet that is what made the six previous generations of BMW's M5 so iconic. 

In seventh-generation ‘G90’ guise, the M5 has another skeleton in the cupboard: the toughest emissions regulations that Europe, and now Australia, have ever seen.

A twin-turbo V8 was untenable and going battery electric was not an option. Plug-in hybrid was the only answer. For the new M5, BMW combined a revised 4.4-litre ‘S68’ bent eight with a punchy electric motor for 535kW and 1000Nm. 

Problem is, the G90 is widely acknowledged as one of the greatest BMW M cars of all time, especially in CS trim. And thanks to a circa-600kg weight hike to nearly 2500kg, the new M5's 0-100km/h claim is actually slower than the old 'F90' M5. 

Doesn’t exactly sound like a big leap forward, does it?

A drive through the Central West of NSW and around the iconic Mount Panorama racing circuit gave us answers to two questions. Does the M5 work on Australia roads, and does BMW M's latest super-sedan represent progress?
