BMW M5 vs BYD Sealion 6

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?

BYD has made a big impact in a short space of time in Australia and the arrival of this all-new mid-size SUV opens the door for an even bigger future.

BYD has taken the fight to Tesla in the electric vehicle contest, and while still some margin behind the American brand the Atto 3 and Seal remain amongst the most popular rivals to the Model 3 and Y, respectively.

At the same time it has out-sold established brands including Honda, Skoda and Renault, as well as fellow Chinese newcomers LDV and Chery. 

Now BYD has its sights set on upsetting the established order in one of the biggest segments in the Australian market - mid-size SUVs.

The Sealion 6 is not a name that rolls off the tongue but it does leave an impression, as does the car, as we discovered when we drove it.
