2021 Brabus 900 Rocket Edition: Tuned Mercedes-AMG G63 gets bigger engine, upgraded interior and more aero

The 2021 Brabus 900 Rocket Edition – which is an aftermarket tuned version of the already-formidable Mercedes-AMG G63 – has been revealed, with increased engine capacity, more power, new aerodynamic features, and a modified interior. Power comes from a 4.5-litre twin-turbo petrol V8, essentially a bored-out version of the 4.0-litre block in the G63. This has been retuned to put out 662kW/1250Nm, up from 430kW/850Nm in the 'garden-variety' performance SUV.
