333 km/h in a Mercedes-Benz CLS 63 AMG isn’t possible normally. The limiter is placed on 250 km/h and you have to pay some extra money to choose for the AMG Drivers package which has a top speed of 280 km/h. When this isn’t even fast enough there are several choices for a step further. Good choice is to visit Carlsson, a well-known tuner. They can make sure that your CLS reaches a top speed of 333 km/h, you can see this in the following movie!
