Admit it: the 10-year-old in you is doing a little happy-dance right now. This is the gloriously excessive Brabus Rocket 900, and yes, it does have one of the most childishly awesome names ever given to a car. It’s called that because it has 900 metric horsepower, or 888bhp in English, and goes like the proverbial Soyuz. Brabus, which has a long and hilarious history of tuning Mercedes cars to their extremes and beyond, has taken the 6.0-litre V12-poweredMercedes-AMG S65 Cabriolet and decided that, actually, it wasn’t fast enough. Someone in Bottrop might have had one beer too many this time… The tuning process starts with more capacity. The V12 has been bored and stroked to 6.3 litres, with a special Brabus billet steel crankshaft and con-rod set. The exhaust manifolds are new, the new turbochargers are larger and there’s a free-breathing exhaust system making all the noise.
