What you see here is a Mercedes customized by Brabus! This Brabus Cabriolet is literally a rocket sled and is called the Brabus 850 Biturbo 6.0 Cabrio! The donor vehicle which is the Mercedes AMG S63 packs 577HP! However, Brabus totally overhauled the engine!
Brabus tuned the engine from 5.5L to 6.0L! The Brabus has a new crankshaft, connecting rods, forged pistons, intake module, cylinder heads, exhaust system and turbochargers as well! All these modifications increased output to insane 838HP! The Brabus Cabriolet 850 can go up to 62mph from zero in just 3.5 seconds! It also has a top speed of 217mph!!
