McLaren Artura vs BMW M5

What's the difference?

Obviously the headline item of the new McLaren Artura Spider is the ability to drop the top and feel the wind in your hair, or, should you live in Melbourne, at least the damp mist on your face.

But this new plug-in powerhouse has plenty more to offer than just its folding hardtop.

The coupe and convertible are more powerful, there’s a new and louder exhaust, faster gear shifts, a richer rev range, better suspension and better braking.

Oh, and there's a new feature designed to unlock your inner hooligan, but we’ll come back to that one in just a moment...

But at its core, the Artura Spider is a plug-in hybrid monster that goes someway to previewing the future of the supercar species.

Does electrification enhance the excitement? We strapped in to find out.

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?
