BYD Sealion 6 vs MG Mgs6 Ev

What's the difference?

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.

BYD, Chery, GWM and MG - one of these Chinese car brands is not like the others.

While the first three all enjoyed major growth in 2025, MG had a year to forget. A flood of new models, rushed into the market with little or no fanfare, resulted in a nearly 20 per cent sales decline, when the brand should have been basking in the same growth as its rivals.

So, the old management has been swept away and MG Australia is attacking 2026 with a fresh outlook and a renewed purpose, fully aware that launching an affordable car and hoping the buyers come is not a sound strategy.

Which is why the brand is making a far more concerted effort with this all-new MGS6 (all one word, likely to avoid copyright issues with Audi). It’s an important model to get right, too, as the electric mid-size SUV is becoming an increasingly popular choice for Australian buyers, as witnessed by the success of the BYD Sealion 7 and Tesla Model Y.

But with those two, plus many more mid-size EV SUVs, including the Kia EV5, GAC Aion V, Geely EX5 and Zeekr 7X (to name a few), to compete with, MG will need to put its best foot forward to give the MGS6 its best chance of success.

This one model alone won’t determine the fortunes of MG in the final reckoning of the year, but if MG wants to turn around its sales numbers and enjoy the same growth as its Chinese rivals, having the MGS6 succeed would be an important step.
