The Brabus Rocket is the world's fastest four door at 227.2 miles per hour. It does 0-60 in four seconds flat and is quite simply an amazing and terrifying vehicle. It is, however, based on the old Mercedes CLS and we would like to see a new one. Jusging by this teaser photo that Brabus recently released a new one could very much be in the works... excellent.
