The 3.0-liter, 240-hp diesel that first served in the Audi Q7 has been assigned to duty in the Audi A4. We drove the 3.0 in the Q7 during last year's Audi Mileage Marathon, and both mileage and power didn't disappoint. Put into the A4, the oil burner with 369 lb-ft should shine like Alpha Centauri.

Audi says it will get you to sixty in 6.2 seconds with the six-speed Tiptronic and return 35 mpg at the same time as it already meets the Euro 6 standards coming in 2014. It's unlikely we'll get the treat in this corner of the Western Hemisphere, but that doesn't mean we won't keep looking out for it... especially as an Avant... with those wheels...

PRESS RELEASE

The Audi A4 3.0 TDI clean diesel quattro – Highly efficient and extremely clean

* The world's cleanest diesel technology now also in the A4
* Midsize sedan consumes only 6.7 liters per 100 km (35.11 US mpg)
* Powerful engine with 240 hp and 500 Nm (368.78 lb-ft) of torque

Using the world's cleanest diesel technology, the 3.0 TDI clean diesel already meets the Euro 6 emission standard not scheduled to enter into force until 2014. Having debuted in the Audi Q7, the innovative engine is now coming to the A4. The powerful TDI is not only extremely clean, it is also highly efficient, using only 6.7 liters of fuel per 100 km (35.11 US mpg) in the EU cycle.

The technology package of the 3.0 TDI clean diesel quattro comprises the engine itself and the highly efficient exhaust gas after-treatment system. A new common rail injection system that develops pressures of up to 2,000 bar, innovative combustion chamber pressure sensors and an ultra-high-performance exhaust gas recirculation system ensure highly efficient combustion which produces minimal raw emissions.

A novel DeNOX catalytic converter at the end of the exhaust system reduces nitrogen oxides. Just upstream of it, a pump injects an aqueous additive named AdBlue into the hot exhaust flow, where this solution decomposes into ammonia, which splits the nitrogen oxides into nitrogen and water. The tank is large enough that the driver never has to refill it. This is done instead by the Audi dealership during scheduled maintenance.

Using the world's cleanest diesel technology, the Audi A4 3.0 TDI clean diesel quattro meets the Euro 6 emission standard announced for 2014. It is also very fuel-efficient, averaging only 6.7 liters (Avant: 6.8 liters) of fuel per 100 km (35.11 and 34.59 US mpg).

The innovative V6 TDI engine makes the A4 a powerful performer, needing only 6.2 seconds (Avant: 6.3 seconds) to go from zero to 100 km/h (62.14 mph). Top speed is electronically governed to 250 km/h (155.34 mph). The combination with the six-speed tiptronic and quattro permanent all-wheel drive ensures a high degree of comfort and superior traction.
