This week's unveiling also confirms speculation that the GLA's design would not stray far from the muscular look of its concept progenitor.
Its proportions have changed however, measuring 44mm longer, 84mm lower and a significant 173mm narrower than the concept.
That also makes the GLA noteably larger now than the A-Class hatch, although both ride on the same 2.69 metre wheelbase.
The cabin of the new crossover also takes more than a few cues from the A-Class, while adding a number of bespoke showcar-only features.
The GLA's engine options will be familiar fare, and we can likely also expect a top-shelf 265kW GLA 45 AMG hero model.
The GLA 200 will feature a 115kW 1.6 petrol engine, and the GLA 200 CDI will get a 100kW 1.8 litre diesel.
Moving up to the top end, there's the 155kW/350Nm 2.0 litre turbocharged GLA 250, and leading the diesel end is the 125kW/350Nm GLA 220 CDI.
Fuel consumption figures vary from an impressive 4.3 l/100km for the GLA 200 CDI to 7.1 l/100km for the GLA 250 sports model.
All-wheel-drive 4Matic versions will also be available for all but the GLA 200, which will be front-wheel-drive only.
Rear storage capacity ranges from 421 litres with the back seats upright, to 836 litres with those seats laid down.
The GLA is expected to hit Australia in the second half of 2014, with more details to be confirmed closer to launch.
