Holden Acadia vs Mercedes-Benz GLA250

What's the difference?

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.

Buuuuuuuur, parp, buuuuuuuuuuuur, parp. Anyone who knows anything about cars immediately recognises the sound of a 45-engined A-class derivative. It's the sound you hear in a tunnel as old mate blasts past with a giant carbon-fibre wing atop his hatchback. It's the sound you hear at 3:00am on a summer morning (if your suburb has no speed bumps, of course).

In short, that sound means big power from a 2.0-litre turbocharged engine, a seven-speed transmission, and a bunch of Germans who clearly had a sense of humour in charge of tuning the exhaust note.

Sure, the GLA compact SUV is probably a slightly unexpected source of all that noise. But then, Merc's Ingolstadt rivals stuffed Audi's stupendous five-cylinder engine into a Q3 to make the hugely improbable RSQ3, so why not do the same with their skirts-lifted A-Class?

To be honest, my expectations for this car were low. So do I owe Mercedes a grovelling apology? Or can I still claim the moral high ground after a week of GLA 45 "ownership"?
