Audi specialist tuners B&B have been the first to take the super diesel V6 to the max in an A6 Avant. The 3.0-liter TDI Biturbo has been tuned with three levels of output - 340, 365 and 390 HP respectively.
The first kit brings the V6 diesel engine to 340 hp by only tweaking the electronics and boosting the pressure of the turbos, all for just under €1,500. The second level of performance raises the output of the engine to 365 hp via the same soft of improvements and costs €1,700.
The last stage of the program brings some more serious toys to the game - custom intake, injectors, air ducts and intercooler. All this, plus the 390 hp will cost you €4,950.
Besides these mods, the Audi A6 Avant can be retrofitted with a lowering kit that brings it 30 mm closer to the ground, or and adjustable coilover system for €1,500. A custom sports exhaust that adds anywhere between 5 and 8 hp is available for €1,300.
