GLC 63 Stage 3 and C63 Stage 4 – infinitas

GLC 63 700 hp & C63 860 hp

The infinitas AMG twin pack: two unique power monsters with impressive performance. After our cure, the GLC 63 has an output of 700 hp and 930 Nm with TÜV, while the C63 has been given a more brutal upgrade with 860 hp and 1050 Nm! Together, the vehicles have an output of almost 1600 hp.

Of course, technical modifications had to be made to both vehicles in order to achieve this level of performance.
The GLC 63 was fitted with an infinitas CPC control unit module (this removes the torque limiter, enables the VMAX boost and the flap control can be adjusted on request), a sports air filter, infinitas Stage 1 upgrade turbochargers with ball bearings, an adapter for the fresh air duct (spacer to increase the distance between the air filter and housing, increases the intake cross-section by over 100 %, provides more power, relieves the turbochargers and looks standard), reinforced recirculation valves and an infinitas rear silencer.
The C63 got almost identical changes, but it also got Stage 2 infinitas ball bearing upgrade turbochargers, downpipes without catalytic converters, an infinitas engine boost with compression-reduced pistons and external gearbox oil coolers to reduce the intake and charge air cooling temperature.
Both vehicles were then individually tuned on the in-house dyno.


Both vehicles were fitted with an infinitas AMG sports steering wheel, infinitas lettering and infinitas interior floor mats. The GLC also received an infinitas decor set. However, we also offer other options, such as a complete interior refinement, customized to your own individual wishes. < By request > you can refine your interior according to your own taste.

More power possible

infinitas stands for almost unlimited possibilities and the highest quality! That’s why 860 hp is not the end of the story, because we can also offer performance beyond that for vehicles with the M177 engine. Power above 860 hp is also possible on request. There are also expansion stages with the option of TÜV registration. < Send inquiry >
