2021 BMW 8 Series Summary

The right lane on Aussie freeways is occasionally referred to as the ‘fast lane’, which is laughable because the highest legal speed in the entire country is 130km/h (81mph). And that’s only on a few stretches in the Top End. Other than that, 110km/h (68mph) is all you’re getting.

Sure, a 'buck thirty' isn’t hanging around, but the subject of this review is a 460kW (625hp) four-door missile, capable of accelerating from 0-100 km/h in 3.2 seconds, and on to a maximum velocity somewhat in excess of our legal limit. 

Fact is, the BMW M8 Competition Gran Coupe is born and bred in Germany, where the autobahn’s left lane is serious territory, with open speed sections, and the car itself the only thing holding you back. In this case, to no less than 305km/h (190mph)!

Which begs the question, isn’t steering this machine onto an Aussie highway like cracking a walnut with a twin-turbo, V8-powered sledgehammer?

Well, yes, But by that logic a whole bunch of high-end, ultra high-performance cars would instantly become surplus to requirements here. Yet they continue to sell, in healthy numbers.  

So, there’s got to be more to it. Time to investigate.

2025 Mercedes-Benz AMG GT Summary

Once upon a time, people would dream about owning a Mercedes-Benz 450SLC – the C107 sports/luxury coupe flagship of the 1970s.

Sexy, stylish, secure and incredibly solid, it embodied the brand’s ‘Engineered Like No Other Car' mantra of the era.

Today’s all-new, second-generation, C192 AMG GT Coupe is something of an indirect descendant of this sort of thinking, changing tack from its supercar-esque 2014 C190 predecessor, with more space, more seats, more sensibility and, conversely, even more steak and sizzle from its glorious V8.

A modern-day SLC? The Porsche 911, Aston Martin DB12, Maserati GranTurismo and Bentley Continental GT’s worst nightmare? Or something else entirely?

These questions and more are answered below.
