So far, Mercedes and BMW have played a game of tit-for-tat when it comes to fastback SUV models. First came the X5-based X6, then the X3-based X4. Mercedes-Benz countered with the GLE Coupe and now GLC Coupe models, both based upon their wagon counterparts.
If previous form is to be a guide, then, Mercedes should be looking at a 'coupe' derivative of the small GLA SUV to counter.

There was a bit of a buzz about the GLA Coupe earlier this year, when an internal Mercedes-Benz presentation was leaked, showing the GLA Coupe in line for a 2017 release. Mercedes quickly corrected the slide, claiming it was a typo and should have read GLA Facelift.
Clerical errors aside, could a GLA Coupe be the next cab off the rank? And what would it look like?
The GLA, in its hatchback form, is hardly a big car. Our reviews have noted that rear head room is already getting tight, plus the 421-litre boot would likely be further reduced.
Fair to note, though, the top-selling compact SUV in Australia, the Mazda CX-3, has just a 264-litre cargo hold, so maybe it isn't that big of an issue.
But could an updated MFA2 GLA also spawn a coupe?

One option would be in utilising a three-door layout. We haven't seen that on sale since the old second-generation A-Class, and then in 2012 as the Concept A-Class. It never made it to production, but Range Rover has persevered with a three-door Evoque (not to mention a new convertible), so it might be an option.
A three-door GLA Coupe would help deal with rear passenger and cargo space, by simply not being practical enough for four-up buyers to consider!
Imagine, a high-riding, three-door, GLA45 Coupe. It would be even more like a rally car than the GLA is now!
Or - and strap in for this one - is the GLA actually already the MFA-platform coupe, with the new GLB SUV swapping the order to become the missing-link wagon?
The BMW X2 is due to hit the streets in 2018, so if it's keen to follow suit, Mercedes-Benz would want to get its skates on.
