Audi unveiled the new Audi A6 sedan at the 2011 North American International Auto Show in Detroit earlier this year, but the wagon version has been withheld until now. It is expected to feature the same trim and engine packages as the Audi A6 sedan, revealed last December.

Kicking off the range of petrol options will likely be the 2.8-litre FSI V6 producing 150kW of power and 280Nm of torque. The 3.0-litre TFSI V6 engine producing 220kW and 440Nm is also said to make its way into the line-up. Respective fuel consumption ratings are 7.4L/100km and 8.2L/100km, although these figures are for the sedan and may change slightly for the Avant.

A range of diesel engines is set to make its way into the Avant range too, including the entry-level 2.0-litre TDI producing 130kW and 380Nm, as well as a 3.0-litre TDI V6 producing 180kW and 500Nm of torque. Fuel consumption figures for the sedan versions of these engines read 4.9L/100km and 6.0L/100km, respectively.

Some versions will be equipped with Audi's quattro all-wheel drive system and a hybrid setup is also rumoured to be on its way. We'll be sure to provide all the details from the unveiling next week. Stay tuned.
