This is the first sighting of Mercedes's facelifted hot crossover model and shows that its visual updates will mirror those applied to the 2017 GLA, which has itself only just been previewed in a single teaser image.
The biggest changes to the GLA 45 are focused around its front and rear, where new bumpers and sleeker headlights will give the car a refreshed look. The styling tweaks will bring the GLA models more into line with the closely-related A-Class range.
Unlike the regular GLA, the more potent 45 model doesn't look to have gained a raised ride height compared to its predecessor, and instead continues to sit only slightly higher than the AMG A 45 hatchback with which it shares many parts.
Along with the rest of the 2017 GLA range, the 45 will get Apple Carplay and Android Auto integration in its infotainment system, as well as a redesigned touch screen.
Under the bonnet of the GLA 45 will be the same turbocharged 2.0-litre four-cylinder engine that's featured in the A 45 hatch. Peak power output is expected to remain 376bhp like the outgoing car, as is torque, which currently tops out at 350lb ft at 2250rpm.
This should mean the facelifted all-wheel drive performance crossover will match the straight-line performance figures of the pre-facelift car, which can accelerate from 0-62mph in 4.4sec and onto a limited top speed of 155mph.
