2011-2012 Volkswagen Passat: The Details

Reviewers aren't sure what to make of the car because of that unusual status, floating between affordable and luxury classes. The 2010 Volkswagen Passat, most critics say, is an enjoyable car to drive. It offers a refined, smooth ride, and sharp handling for a family car. Its interior is a step up from those of most Affordable Midsize Cars, with high-quality materials and fine attention to detail.

The SCR catalytic converter of the Passat BlueTDI together with the additive AdBlue selectively converts nitrogen oxides (NOx) in the exhaust stream into nitrogen and water. This is in addition to an oxidation catalytic converter and diesel particulate filter which are also used to reduce the entire range of emissions. AdBlue is carried in an auxiliary tank. It is sprayed into the exhaust stream by a module downstream of the diesel particulate filter and oxidations catalytic converter. The fluid is metered according to the exhaust mass flow rate. Engine management ensures precise control based on information from the NOx sensor.
