BMW M5 vs Toyota Prius

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?

What to say about the Toyota Prius in 2021? A car that was once a technology trailblazer seems now to have become properly retro, even while it’s still being built and sold.

The awkward-looking wedge, an eco-punk icon, not only brought Toyota’s hybrid synergy drive to the masses, it also debuted the brand’s excellent TNGA architecture and set the scene for the company's absurd hybrid success, which now sees the RAV4 version topping the sales charts.

So, after all these years (25 to be precise), is the Prius’s time finally over? Or does this quaint hybrid hero still have more to offer? I took a top-spec I-Tech for a week to find out.
