BMW M5 vs Audi R8

What's the difference?

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?

Supercars can sometimes be seen as the divas of the auto world – delicate, over-the-top, not very good with reality. Well that may be the case for some supercars but not Audi's R8. It's affordable by supercar standards, easy to drive and still very, very fast.

Now the updated R8 has arrived, looking fiercer than ever, but remaining one of the smartest supercar buys on the market. But did you know there are two types of R8? Both have very distinct personalities and I lived with them for two days – in the reality of road works and also ideal country roads.
