2025 BMW M5 Summary

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?

2018 Hyundai I40 Summary

A wagon and not an SUV, eh? Respect. You see, when most people now think of a new car they think of an SUV, especially when they want something with a bit of cargo space. But not you.

And for thinking outside the box you’ll be rewarded with something that’s better to drive than most SUVs – like the Hyundai i40 Tourer in the Active grade and a diesel engine we’ve road tested here.

So, what are the strengths and weaknesses of this Korean wagon, and should you wait or buy it now? Read on to find out.

Verdict

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.

Verdict

The i40 Tourer in the Active grade is great to drive, it’s practical, and should be low-cost to run. But you can bet the new version, due to arrive soon, will be, too. If you can wait, it's a safe bet the new i40 Tourer will have an updated look, improved safety equipment and retain all the good points of the previous model.
