Volkswagen announced at the International Vienna Motor Symposium in Austria that it has completed development of its U.S.-spec BlueTDI diesel. The first use of the clean diesel will be in the Volkswagen Jetta diesel, which will be the first Tier2 Bin5 complaint diesel not to require urea injection.
The Jetta’s clean diesel engine is based on the European 2.0 TDI. Through the use of cylinder pressure sensors and the engine management system, VW engineers were able to control combustion temperature and therefore eliminated 60 percent of NOx emissions. An NOx trap further downstream is able to convert the remaining NOx to nitrogen and water.
According to VW, the new BlueTDI will get about 60 mpg on the highway — a 12 percent improvement over the last diesel-powered Jetta.
The first Jetta BlueTDIs will start showing up at VW dealerships for test drives in June, with the car officially going on sale in September.
