Porsche Panamera vs BMW M5

What's the difference?

Australia hasn't had what you'd call a love affair with the Porsche Panamera. Especially compared to the on-going romance with its iconic sibling, the 911 and even its SUV stablemates. 

The Panamera straddles the fence between high-performance sports car and family sedan and it's a position rivals like the BMW 740i, Maserati Quattroporte and Mercedes-Benz S450 have sometimes found difficult to balance.

This new-generation 'base' Panamera model is on test to see if this sedan's 2025 redesign will launch an arrow from Cupid's bow for Australian families?

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?
