Volkswagen is recognized as one of
the leading small diesel engine manufacturers, and is partnering with Mercedes and other companies to market BlueTec clean diesel technology, calling it BlueMotion.
As demand for
diesel engines in standard sedan and station wagon cars in the United States has traditionally been much lower than in saloon and estate cars in Europe, the development of
smaller automotive turbodiesels has (in general) been
led by European manufacturers in recent years.
