Audi RS3 vs BMW M5

What's the difference?

Five-cylinder fury is still kicking!

Audi has just launched the mid-life updated version of its RS3 hatch and sedan in Australia.

With new looks inside and out, the German carmaker has also made a number of subtle tweaks under the skin via software updates. Thankfully, however, the five-cylinder beast lurking under the bonnet remains untouched.

As the viability of pure internal combustion engines in the hot hatch segment dwindles in the age of ever-tightening emissions regulations, will this be the last hurrah for the five-banger RS3?

Read along to see how this latest version stacks up.

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?
