2021 BMW M8 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.

2026 Mercedes-Benz GLE450 Summary

Well into its second generation, the Mercedes-Benz GLE remains a key player in the luxury large SUV space.

Though it lags well behind the BMW X5 in terms of sales, by about half in fact, the GLE still aims to exude status and luxury, helped by a facelift in 2023.

In its category, there are however plenty of badges with the power to lure buyers away: Audi, Porsche and Range Rover. Even non-Euros like Genesis and Lexus.

Despite the facelift, the category is moving on with big screens and more tech, where the GLE still has to rely on some traditional charm to win over wallets - especially in our big diesel ‘450d’ guise.

A week behind the wheel around and out of the city should reveal whether the GLE still has a strong-enough USP in 2025.
