Clean Diesel Jetta by Volkswagen

Diesel-powered engines are mostly considered as emitting harmful emissions and used mostly on trucks and sports utility vehicles. Hybrid is the “in thing” when it comes to saving the environment from harmful emissions and many automakers have contributed their share of Hybrid vehicles.

However, Volkswagen didn’t follow that stereotype on diesel engines and they came up with their own clean diesel technology and incorporated it into their 2008 Jetta Diesel prototypes. Its clean diesel technology runs in the form of a 2.0L four cylinder common-rail diesel engine that meets the Tier 2 Bin 5 emissions standards of the 50 US states.
