Volkswagen’s BlueTDI engine technology, a next generation turbo diesel developed especially for the North American market is set to debut in the Jetta in mid 2008 according to a company release. This common rail engine is based on the high-tech TDI, which was first introduced in Europe in 2007 with the Tiguan. The BlueTDI engine already satisfies the Euro-5 standard that comes into effect in autumn 2009 but in order to meet specific operating conditions in some states of the U.S. (eg- California), this 4 cylinder engine was modified.

The Jetta BlueTDI is touted as one of the cleanest and most economic
cars of its class in the world. On the highway, for example, this engine can reach up to 60 miles per gallon! The 2.0 litre engine is also not a slouch with 140 PS and 320 Nm of torque.
