CLK 270CDI with soot filter?

Hello MB CLK Freak`s, someone has already heard of the soot filter offensive for diesel vehicles from DB at the Frankfurt Motor Show? Mercedes should equip its diesel engines from the 400 CDI upwards with soot filter so that they reach the pollutant standard 4. What about the power and when will the “smaller diesel” like the 270 CDI get in the CLK? For the built-in soot filterer, which cannot be retrofitted, a car tax saving of over 650.00 euros from the St That would be a positive Diesel message, wouldn’t it? Who has heard something more about it, please report!!! Greetings to all CLK drivers, Josti, the CLK Newbie.
