Peugeot 508 vs BMW M5

What's the difference?

The humble station wagon has fallen by the wayside in favour of the ever-popular SUV, however, it was once more common for a very good reason.

It offers the space many families crave without having to upsize into a vehicle that can feel big and bulky.

A lot of drivers enjoy the sportier on-road feel and the good-looking styling that often accompanies a wagon. Enter the Peugeot 508 Sportswagon. A model that proves wagons can be hot.

I’m family-testing the top GT plug-in hybrid model this week but there’s not a lot to compare it to because of the interesting engine specs.

So, we’re being a bit cheeky and doing an ‘apples with oranges’ comparo instead.

Being on the premium end, the 508 Sportswagon faces competition from the Audi A4 Allroad 45 TFSI, Genesis G70 Shooting Brake and Volvo V60 Cross Country Ultimate.

It certainly has the looks to turn heads but we’re sussing out whether it’s a practical alternative for families, too.

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?
