BMW 630I vs Holden Acadia

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.

If the Acadia had an accent it would be a southern drawl because this big seven-seat SUV is built in Tennessee, USA, and wears a GMC badge when it’s at home.

In Australia of course it wears a Holden one and comes straight from the factory in right-hand drive. So how does it suit Aussie conditions? Does it even know the importance of a sausage on a piece of bread bought outside a hardware store on a Saturday?

All this and more was learnt when the entry grade LT front-wheel drive came to live with my family.
