And not only does the heavy-hitting GLA 45 AMG get a bump in output to 294kW/500Nm (up from an already substantial 265kW/450Nm), but even the GLA 220 CDI (not available in Australia) sees another 30kW added to its output.
With Brabus' tune, the GLA 45 zips to 100km/h in just 4.4 seconds - 0.2 seconds faster than an A 45 AMG - while the speed limiter is reset to 270km/h.
No power upgrades are listed for the mid-grade GLA 250, though Brabus sells an active exhaust for the 250 that increases exhaust volume at the press of a button.
Brabus has also revealed its cosmetic parts for the GLA, with a unique front bumper insert, rear bumper insert, a range of alloy wheels spanning sizes from 18 inches to a monstrous 21 inches and a rear spoiler.
Also available are two different suspension upgrades, one of which raises ride height by 30mm, the other lowering ride height by 25mm.
Inside, Brabus offers alloy pedals, illuminated kickplates and extended aluminium shift paddles, as well as alcantara or leather upholstery in your choice of colour.
