Genesis G80 vs MG Im6

What's the difference?

Remember those extra-long Australian luxury sedans like the Ford Fairlane and Holden Statesman/Caprice?

The patriotic choice in an era where that mattered and further protected by tariffs on imports that made them barely any more expensive than a base mid-sized Euro like a BMW 318i, they dominated the top end of the market with their sheer size outside, vast space inside and big-six or V8 grunt.

Like they used to say, there is no substitute for cubic inches.

Well, the spirit of these beloved local social-climbing classics lives on in just one modern car in 2025, the Genesis G80. Over three generations since 2008, it has been Hyundai’s tilt at the premium establishment, in much the same way as the Fairlane and Caprice were, and Toyota’s Lexus luxury brand still is.

We take a dive into the latest petrol-powered range-topper version, the 3.5T All-Wheel Drive (AWD) Sport Luxury (SL), which gives off more than its fair share of vintage HSV Grange vibes.

Meet the IM6 Performance, “presented by MG”. And that last bit’s important, because while it’s marketed and sold by the Chinese mainstream player, it really is unlike any other MG going around.

Think of it as like a Lexus to Toyota, or an Audi to Volkswagen, with the Chinese brand going premium, and seemingly making a direct play for Tesla’s fan base. How so? Well, there’s only two models in IM line-up (sound familiar?) with the IM6 a rival for the Model Y, and the IM5 (which we’ve also tested) a competitor to the Model 3.

The IM6 is spacious, pretty sumptuous and ridiculously fast. And it offers up some features I’ve only ever really seen in high-end German metal. But it’s also got some quirks.

So, can MG run with the big dogs of the premium car world with the IM6 Performance? And should Tesla be worried? Let’s find out.
