A German tuning operation called Posaidon has developed a power upgrade package for the G-Class AMG.
The standard turbochargers on the 5,5-litre V8 engine have been replaced with bigger ones, while Posaidon has also done some work on the intercooler. Other upgrades include a louder sports exhaust system, reworked ECU and some minor modifications to the standard seven-speed automatic gearbox.
The result is 610kW and 1350Nm of torque, which is enough to get the massive G-Class to 100km/h in 4,2 seconds.
