BMW 8 Series vs Mercedes-Benz GLB

What's the difference?

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.

A new-generation Mercedes-Benz GLB is just around the corner, so the current model is now on its farewell tour.

When it launched in 2019 it stood out from the crowd as a premium small-to-medium SUV with the flexibility of seven seats. Even now no other premium carmaker offers a car that’s a direct rival to this. You need to look at mainstream options instead that are slightly larger.

A mid-life update that arrived in 2023 brought some minor tweaks including different exterior and interior styling, along with mild-hybrid power for certain variants.

On test here is the entry-level GLB200 which didn’t receive mild-hybrid assistance. Read along to find out whether it’s the pick of the line-up.
