German tuners Posaidon has released the most powerful street legal Mercedes-AMG E 63 package it has ever created, called the RS850+.
The RS850+ is based on the Mercedes-AMG E 63, using a heavily modified 5.5-litre twin-turbo V8 now producing a mega 760kW of power (1020hp) and 1400Nm of torque.
In order to achieve this, the team at Posaidon had to swap out nearly all of AMG’s work on the powertrain, adding heavy-duty componentry, two larger turbochargers, a re-mapped ECU and a tweaked version of Merc’s 4Matic four-wheel drive system and limited-slip differential.
In addition, the team at Posaidon have added 420mm carbon-ceramic brakes with six-piston calipers up front, and 360mm four-piston brakes at the rear. These are hidden behind 20-inch alloy wheels wrapped in 255/30R front and 295/25R rear rubber.
The end result is a 0-100km/h sprint in a claimed 2.8 seconds, and a top speed of 368km/h, well above Mercedes’s speed limiter.
Weight saving has taken many shapes and forms in the RS850+, but none more-so than the removal of the E 63’s rear seats, and front seats that are replaced with C 63 AMG Black bucket seats, saving 40kg.
The exterior has received the Posaidon touch too, with a much more race-inspired aesthetic, including a carbon fibre bonnet, front bumper, rear diffuser, rear wing, mirror caps and exhaust tips.
