The debut this week of the new topless top-shelf tourer follows the unveiling in December of the regular SL-Class, headlined by the flagship SL 550 variant.
In SL 63 AMG form, the new convertible is the company's new 5.5 litre twin-turbo V8 engine, delivering 400kW and 800Nm of torque.
Thanks to the new SL's lighter body and its new eco stop/start system, Merc says the new AMG version returns fuel consumption figures 30 percent better than the outgoing model.
Mercedes says the new SL 63 will hit 100km/h in 4.2 seconds, but opt for the AMG Performance Package, which lifts output to 510kW and 900Nm, and you'll unlock a slightly quicker 4.1-second sprint.
In both cases, power is sent to the rear wheels through AMG's trusty Speedshift seven-speed automated-manual transmission.
The SL 63 AMG also benefits from performance suspension, 19-inch alloy wheels and more powerful braking system, featuring six-piston calipers up front.
With the AMG Performance Package, the wheel arrangement is upgraded to 20-inch rims at the rear, and 19s at the front.
Speaking with TMR today, Mercedes-Benz Australia's Jerry Stamoulis confirmed a third-quarter debut for the new SL 63 AMG.
