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?
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.
Let’s get one thing out of the way: the new M5 is a very good car. Considering the emissions limitations and size increase of its base model, it is an impressive bit of engineering.
What’s trickier is deciding whether the new car is really better to drive. Less edgy but supremely comfortable and quiet; BMW leaned into the daily usability of the plug-in hybrid M5 rather than amping the petrol-electric system for maximum thrills. And do you know what? That’s fine with me.
The new M5 still performs on road and track and does an incredible job of hiding its weight (most of the time). Perhaps the G90 is a little more Audi RS6 than F90 in its demeanour but some would argue that’s no bad thing.
The concept of the BMW M5 is not static, it evolves with the times, and the G90 is no exception. Expect future Competition and CS variants to unlock some extra lunacy.

Overall, then, the flagship G80 tries to be docile Clark Kent and the amazing Superman in one. As such, it stretches itself trying to be both a luxury GT and high-functioning sports sedan.
But while it doesn’t quite achieve either perfectly the Genesis gets near enough for most – especially at its exceptional price point.
