As expected, the high-riding hot-hatch is identical to its the 'concept' revealed in November, with only the lary graphics and large rear wing left out of the production formula. (The wing will likely return as an option.)
Debuting less than six months on from the international unveiling of the regular GLA range, the new AMG SUV continues the trend of offering a high-performance flagship in just about every range Mercedes has to offer.
Like the AMG-powered A and CLA models, the GLA 45 is driven by a turbo 2.0 litre four-cylinder petrol engine punching out a meaty 265kW and 450Nm, sending power to the all-wheel-drive system through a seven-speed dual-clutch auto.
AMG promises a 0-100km/h time of 4.8 seconds, making the compact SUV just 0.2 seconds slower than the punchy little A 45.
Top speed is listed at an electronically limited 250km/h, and fuel consumption is rated at 6.9 l/100km.
Being a performance hero model, the GLA 45 sits lower on AMG-specific sports suspension, adding stiffer knuckles and springs for a sharpened and firmer ride.
The production GLA does away with the concept's 21-inch matte-black wheels, riding instead on 19-inch alloy wheels finished in a titanium grey and wrapped in 235/45 rubber. There's also a 20-inch wheel option, wrapped in 235/40 tyres.
As an AMG model, there's also a unique bumper design at both ends, and an optional carbon package can also be added for exterior and interior upgrades.
Australian launch timing for the GLA 45 AMG is unclear, but expect it to follow the second-half launch of the regular GLA range.
