Mercedes-Benz GLA250 vs Lexus UX250H

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"?

Most cars get secretly cheapened as they travel through their model lifecycles.

Yes, while facelifts often usher in headline advances like updated electronics and more equipment to boost attention, in too many cases, engineers are forced to cut costs, especially where they cannot be very easily detected, such as with removed sound-deadening, inferior carpet quality and deleted minor items, like bonnet struts.

Every cent saved is extra profit made.

Now, we cannot tell at what level – if any – the penny-pinchers pilfered the Lexus UX for its Series II update last year, but the completely unexpected result is a small SUV/crossover that feels and drives noticeably better than before.
