Mercedes-Benz GLA250 vs Audi Q5

What's the difference?

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"?

Audi’s latest Q5 Sportback brings mild-hybrid power, updated underpinnings, more technology and a genuinely impressive interior glow-up. 

It’s clearly aimed at buyers drawn to a more athletic take on the mid-size SUV, where style plays a bigger role than outright practicality. We're testing the base petrol spec to see how it sits alongside the BMW X4 xDrive20i, Genesis GV70 2.5T and Mercedes-Benz GLC300 Coupe.
