Messing with already potent AMG materiel is Carlsson's raison d'etre. This time, they've applied their epic — if not completely ludicrous — tuning capabilities toward the Mercedes SL 55 AMG, to create the CK 55 RS. What they've come up with is a 601-hp fire breather that can top out at 206 mph. As is their MO, they've done it by tweaking the supercharger to increase compressor RPM to, in turn, raise boost pressure. Then, they recast the engine software and added a stainless-steel exhaust kit designed to reduce backpressure. Simple. Such futzing reduces zero-to-62 time to 4.2 seconds. Next, the company plans to offer its C-Tronic automatic suspension lowering kit — coming soon to a left lane near the river Saar.
