The little Merc CLA 45 AMG is already a fast machine but this has not stopped the famous German tuners, Brabus, from giving it an even bigger punch. Their PowerXtra B45 software upgrade takes the stocl 355 hp and pumps it upto a serious 394 hp. This means the car gets to 100 km/h a full 0.2 seconds faster than stock which is 4.4 seconds. Brabus are not known for keeping the car stock visually either and this is no exception. They have gone with a red and black theme which can be seen on the wheels and wing mirrors and other additions such as a carbon front splitter and bootlid spoiler complete the overhaul.
