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 Mercedes-Benz C-Class Summary

When it comes to choosing a family car, sedans are often overlooked for their long-legged wagon or beefy SUV cousins.

They're a bit of a forgotten hero but they'll always hold a piece of my heart for their practicality and (often) sexier kerb-side appeal.

If you can get used to your body cracking like a glow stick when you get in and out of them, the sedan may make a comeback!

The new Mercedes-Benz C-Class, in entry-level C200 form, has definitely tempted my family to consider a sedan in the future – it looks stately and refined but the driving experience also makes it fun.

Let's see what else it did right and if there was anything that could be improved.

Did I mention, I'm fond of sedans... ?

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 Mercedes-Benz C-Class C200 is such a stylish sedan and I would totally have one. The driving performance, luxurious features and practical size made it a winning combo for my family. The price point is definitely up there but you do get a high-end build for the cash. I've seen bigger boots in other sedans and not being able to fit a third child seat will limit some families, but this still easily earns an 8.5/10 from me.

My son really loved this one. The ambient lighting was the highlight for him and he thought it looked like a "space car" inside. He gave it a 9/10.
