Posaidon Boosts Mercedes-AMG GT R To 880 HP, Keeps Original Looks

Tuning company Posaidon has unveiled its most powerful Mercedes-AMG GT model to date based around the track-focused R version.

Powering the AMG GT R is a 4.0-liter twin-turbocharged V8 pumping out 585 HP and 516 lb-ft (700 Nm) of torque. Posaidon managed to bump that up significantly, to 880 HP and 738 lb-ft (1000 Nm), allowing the sports car to reach 100 km/h (62 mph) in a mere 2.9 seconds and hit a 360 km/h top speed.

The key ingredients to this power increase are two bespoke ball-bearing turbochargers, forged high-performance pistons and sports air filters. Posaidon has also upgraded the fuel pumps, fitted new spark plugs, replaced the manifolds and installed new downpipes with sports catalysts, and rounded everything out with some ECU tuning.

Although this particular car is a GT R, Posaidon offers the same upgrade package to the lesser AMG GT, GT S, and GT C models, as they all feature the same engine, only in different states of tune.

What’s refreshing about this tuning job is, that unlike most, it doesn’t including any bold new exterior panels that provide onlookers with a hint of the vehicle’s superior performance. If you were to roll up alongside an AMG GT R like this at a red light, you wouldn’t be able to tell it apart from a stock one. It’s certainly no Q-car (no AMG really is), but it’s as discreet as they come despite the colossal power bump.
