Basically an auxiliary control unit that plugs into the engine’s ECU, the DS6’s forte is that after installation the car remains Euro 6 compliant.
Euro 6 is the tougher standard covering carbon monoxide, particulates, hydrocarbons and nitrogen oxide emissions which comes into force in September 2014. However, it doesn’t encompass CO2, and Brabus isn’t saying whether levels of that particular pollutant are affected or not.
Keeping things clean is not all it does, though. Output from the 2,987 cc turbo-diesel V6 is lifted by over 20% to 308 bhp (230 kW / 313 PS), which just eclipses what a standard petrol-powered S 350 BlueEFFICIENCY can muster. Torque is increased too, rising from 620 Nm (457 lb/ft) to 690 Nm (509 lb/ft).
Cleverly, Brabus has configured the DS6 Performance Kit to work with the different modes of the S-Class’s seven-speed automatic gearbox. In ‘Eco’ only the extra torque is applied, but switch into ‘Manual’ or ‘Sport’ and the additional horsepower is also unleashed.
With full power, the S 350 BlueTEC’s 0-62 mph (100 km/h) time is cut from 7.1 to 6.5 seconds, although top speed remains limited to 155 mph (250 km/h). What’s more, it’s claimed that fuel consumption might actually reduce compared to the stock car. But that will depend on driving style, and presumably sticking firmly to ‘Eco’ mode.
The Brabus Eco PowerXtra D6S Performance Kit is backed by a warranty that lasts three years, up to a maximum of 62,000 miles or 100,000 kilometres. It’s also available for the CLS 350 CDI BlueEFFICIENCY and all E 350 CDI BlueEFFICIENCY models.
