The range will also become incrementally more powerful, with GT models getting small boosts in power and torque.
More importantly, Mercedes has announced the addition of the AMG GT R Coupé to Australia's line-up.
The 430kW/700Nm halo car recently set a new production car record of 2 minutes 16.5 seconds around Mount Panorama in Bathurst.
As well as the GT R Coupe making its way Down Under, the GT and GT S will benefit from little increases in power.
The GT will gain 10kW to bring output to 350kW and gets another 30Nm to total 630Nm. The GT S gets an extra 9kW to bring power up to 384kW and 20Nm to give the car 670Nm.
Mercedes will also bring the AMG GT and GT C Roadsters to Australia, “in preparation for the warmer months to come.”
While the GT Roadster is essentially the same as the Coupe, sans roof, the GT C is an angrier, 410kW/980Nm version of the model.
It also gets rear-axle steering and similar styling to the GT R. The GT C will also be available in Edition 50 Coupe spec until next year. This adds AMG Performance seats and steering wheel, extra detailing, and a plethora of other styling cues.
The GT range updates are due to take effect in October, with MRLP pricing as announced by M-B below:
GT Coupé $258,711
GT Roadster $283,711
GT S Coupé $298,711
