BMW 6 Series vs BMW 8 Series

What's the difference?

What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.

That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.

Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.

I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.

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.
