BMW M5 vs Range Rover Sport

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?

The current Range Rover Sport arrived in 2022, the third-generation version of what has been a super-successful model line for Land Rover, combining sleek looks with top-shelf luxury and a wide range of power and model grade options.

On test here is the P460e Dynamic HSE, a petrol-electric plug-in hybrid sitting in the thick of the upper-luxury five-seat SUV market.

We spent a week behind the wheel to see if it has what it takes to put its nose in front of an impressive bunch of European, more specifically, German rivals.
