Mercedes has been plugging holes in its range over recent years, with cars such as the A-Class family hatch and GLA crossover finally offering real competition to big-selling cars from arch-rivals Audi and BMW.
But while we've had to wait a bit longer for Mercedes to build a mid-size SUV, the next stage in the luxury brand's model offensive is finally here, and the GLC is aimed straight at Audi Q5 and BMW X3 territory.
• Best SUVs to buy
There’s lots to like with these two stylish adversaries though, so the GLC won’t have it all its own way. Being the new kid could work in its favour as buyers look for the latest in a sector where image counts, but the Mercedes needs to have the combination of performance, space and equipment to back up its looks and rise to the top of the class. We’ve lined up high-spec and higher-powered four-cylinder diesel versions of each to see if the car has been worth the wait, and which model is the compact SUV king.

Looks are important in this sector, and the fresh-faced Mercedes arguably has the most appeal here. However, what the badge brings to the ownership experience will hold as much value for some buyers. Our three test cars all have premium images that mean they'll be suited to pretty much every occasion.

BMW's iDrive system is the slickest user interface, but Mercedes' touchpad and scroll wheel isn't far behind. Audi uses a similar set-up, but the small screen and low-res graphics take the shine off a polished system. Audi's newer products excel here, showing the Q5's age.
Adaptive dampers
Electronically controlled suspension is available on all of the cars on test. This widens all three cars' breadth of abilities, making them sportier when you want them to be, and more comfortable when you don't.
