When cars first get released, many tuners jump headfirst into trying to come out with a tuning package that outdoes anything the automaker has already provided. Others seem to be a little slow on the uptake and end up providing packages for vehicles that have been on the market for a little while longer. The Mercedes CLS 63 AMG was unveiled in 2010, but German tuner, MKB, have only recently revealed their upgrade for the luxury sedan, and the added power was well worth the wait.
MKB popped the hood of the CLS63 AMG and tuned the boost pressure, high flow exhaust systems, and ECU management. These powerful modifications gave the 5.5L twin turbo V8 engine a boost to the tune of 122 HP and 221 lb-ft of torque. As a result, the CLS 63 AMG now delivers a total of 640 HP and 737 lb-ft of torque.
With this added power, the Mercedes CLS63 AMG will sprint from 0 to 60 mph in just 4.1 seconds, while top speed goes up to an impressive 211 mph. That top speed is like forbidden fruit, however, because it was kept limited to 186 mph. The added punch is controlled with a new set of 19" or 20" aluminum wheels wrapped around Michelin Pilot Super Sport tires.
