German tuner Posaidon has prepared a massive power upgrade for the Mercedes-Benz G63 AMG.

The G-Class never gets old so that is why many aftermarket specialists are still working on the legendary off-roader which is even more appealing in the AMG guise. Posaidon is a fine example as they have prepared a comprehensive upgrade kit for the G63 AMG which in its stock configuration provides 544 HP (400 kW) and 760 Nm (560 lb-ft) from a twin-turbo V8 5.5-liter engine.

Posaidon replaced the standard turbochargers with more powerful ones and they also worked on the air intake system and intercooler. There's also a custom sports exhaust system, remapped engine ECU and a revised 7G-Tronic gearbox which now has to handle no less than 830 HP (610 kW) and a torquetastic 1,350 Nm (997 lb-ft).

Despite its sheer size and weight, the tuned Mercedes G63 AMG will need only 4.2 seconds to reach 62 mph (100 km/h), thus making it 1.2s quicker than the standard G63 AMG. There's no word about the top speed but we remind you Mercedes-Benz electronically limits the off-roader to 130 mph (210 km/h).
