The signing of Ingolstadt has added to the range of new A8 engines like 3.0 TDI, which reduces fuel consumption and emissions to the point of overcoming future Euro 6 regulations.

Also available in the A8 L body, the 3.0 TDI Clean Diesel retains all its benefits: offers a power of 250 hp, has Quattro all-wheel drive and the multitronic gearbox eight-speed.

To comply with the new standard is necessary to reduce emissions of nitrogen oxides and unburned hydrocarbons. The Audi Clean Diesel incorporates a control system of the injection pressure in the cylinders, a supercharger system and the revised AdBlue catalyst, through which the gases are cleaned better.

The AdBlue consists of urea and water to 32.5% and is a liquid to be filled when playing a maintenance check since, otherwise, the vehicle will not start. AdBlue tanks are located on the underside of the car and have a capacity of 23 liters. So, we only have to travel 2,400 km with that capacity.

The 3.0 TDI Clean Diesel costs with 1,500 euros more than the A8 3.0 TDI basics. Audi introduced the first engine Clean Diesel in its range in 2009 and so far as this alternative offered in the A4, A6, A7 Sportback and Q7. Euro 6 legislation, which comes into force in 2014, requires all cars to not exceed 0.17 g / km of oxides of nitrogen and unburned hydrocarbons.
