ART Tuning released the performance kit “A55K” for the G 55 K. After optimizing the supercharger ratio and the engine management system, the engine’s output goes up from 476 bhp to an impressive 580 bhp. The torque increases from 700 to 790 Nm.
At the same time, A.R.T. also overrides the Vmax limit. As regards the gasoline engines, A.R.T. also takes account of the G 55 (performance boost by means of a supercharger to 440 bhp and 597 Nm) and G 500 (also with a supercharger: 402 bhp; 683 Nm). In terms of the diesels, thanks to A.R.T. DieselPower, the power classes 293 bhp (G 400 CDI, 624 Nm), 261 bhp (G 320 CDI, 600 Nm) and 192 bhp (G 270 CDI, 468 Nm) are possible.
The G-Model owes its new look to a large extent to the A.R.T. “monoART1” wheel rim in a 10x22 inch design, which is usually fitted as part of complete sets of wheels. This 10-spoke wheel rim is available in a stylish TITANIUM finish. A.R.T. also, however, offers its customers a range of different finishes. The wheel rim is fitted with size 285/35-22 tires.
