Brabus is the Mercedes-Benz tuning specialist that we've reported on before in the past. This tuning firm has presented a new Eco PowerXtra D6S performance kit for the S350 BlueTec. Brabus claims to have created the world's first tuned diesel-power car that meets the Euro 6 emissions standard that's set to go into effect in 2014. The kit's performance upgrade delivers an additional 55-horses to the engine, bringing the total to 313-horsepower.

The modified Mercedes can go from 0 to 60 mph in just 6.5 seconds and has an electronically limited top speed of 155 mph. The Brabus ECO PowerXtra D6S can also be fitted to all Mercedes E350 CDI BlueEfficiency variants, as well as the CLS 350 CDI BlueEfficiency model. The great part is that not only can you outfit your MBZ to be more eco-friendly, but you can also get the same output as described for the S350.
