BMW M5 vs Mercedes-AMG GLE63

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 SUV craze is such that high-riding wagons are increasingly being tasked with also doing the job of sports cars, despite the immutable laws of physics clearly working against them.

While the results have been mixed, Mercedes-AMG has some serious form in this area, so much so that it’s been confident enough to unleash the second-generation GLE63 S.

Yep, this large SUV is looking to do its best impersonation of a sports car, so we’re looking to find out if it’s a convincing Jekyll and Hyde. Read on.
