BMW M5 vs Mercedes-Benz CLS53

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?

Mercedes-Benz loves to fill a niche. This is the company, after all, that has a coupe version of its GLC and GLE SUVS, four-door coupes ranging in size from the CLA to the AMG GT 4-door, and enough electric vehicles to make Tesla jealous.

The nichest of all though, might the CLS, which has been updated for the 2022 model year.

Positioned above the E-Class but below the S-Class in the line-up as a sporty sedan for customers after a blend of style, technology and performance, the new CLS is available in just one engine now, while styling and equipment have also been tweaked in the update.

Can the CLS earn its place in the Mercedes line-up or is it destined to be a bit player amongst more popular models?
