Audi A4 vs BMW M5

What's the difference?

The Audi A4 allroad is the off-roader of the A4 line-up. I’m using the term ‘off-roader’ loosely here because this wagon is obviously best suited to daily duties in a city and suburbs, with perhaps an occasional foray into very light off-roading, i.e. driving on a well-maintained gravel or dirt road with few, if any, corrugations, and in dry weather only. 

But that’s not a negative factor because the great thing about adventures is that they can be scaled to suit you, your lifestyle and your vehicle of choice.

However, is this allroad your best option for a comfortable, nice-driving all-rounder? Read on.

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?
