Did Posaidon Just Turn The Mercedes-AMG GT S Into A Proper Supercar?

A top speed of 216 mph is looking good to us.

The Mercedes-AMG GT S is without question an awesome car. That being said it's not really a supercar. It doesn't look the part as it has that roadster on steroids look that, while cool, doesn't really inspire awe. Under the hood, well let's just say its 4.0-liter twin-turbo V8 won't be striking fear into the hearts of engineers at Lamborghini or McLaren anytime soon. Now German tuning house Posaidon didn't change the look of the AMG GT S to make it more supercar-y, but it did beef up the engine a whole hell of a lot.

The Posaidon GT RS 700 has been tuned to put out 700 horsepower and an electronically limited 750 lb-ft of torque, although that torque limit can be lifted if the customer asks. To achieve this power boost an in-house turbo was installed along with a larger intercooler. There's also a custom exhaust and free-flow motorsport grade catalytic converters. The ECU and TCU (transmission control unit) were also remapped. The result is a 0 to 62 mph sprint of 3.2 seconds and an astonishing top speed of 216 mph. Maybe we spoke too soon when we said the AMG GT S wasn't a supercar...
