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?

2023 BMW 3 Series Summary

Back in the day, the 3 Series sedan was often the entry to the brand for first time BMW owners, and for good reason. They offered practical interior space without compromising on engine performance.

And they simply looked good, no boring nanny design elements. Then the 1 Series came along and price points bumped up, so how does the ‘entry’ BMW 320i M Sport live up to its long-standing reputation?

With an updated dashboard that brings the interior and tech up to market and a sharper exterior design, it more than holds its own at the table of luxury sedans, despite hard competition from the likes of the Audi A4, Mercedes-Benz C200 and Jaguar XE.

However, if the Merc is a placid and well-behaved mare… the BMW is the barely-broken-in bronco and it takes a certain kind of ‘rider’ to enjoy what the 320i has to offer.

I’ve been discovering just that this week with my family of three. What did we find out? Read below!

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

I thoroughly enjoyed my time in the BMW 320i M Sport. It’s fun to drive and I felt connected to what the car was doing on the road. The harder ride may not appeal to some but I didn’t mind it. The cosy back seat and boot mean it will probably suit a smaller family best and one which doesn’t have to worry about carrying a lot of gear around regularly, but it suited my needs just fine.

I reckon this is a car for those drivers who don’t want to compromise on performance but still have a kid or two. If you’re after the cushioned comfort of a Merc, this won’t appeal but I didn't want to give this one back and happily give it a firm 8/10.

My son liked the sports car looks and enjoyed the amenities in his row. He gives it a 10/10.
