The conventional diesel engine delivered fuel gas mileage better than their counterparts, and now, the technology give us new solution, the gas powertrains rivals by their emission output. So, there seem to make sense when diesel electric hybrids (adding an electric hybrid system to a diesel) would give us a superb fuel economy green vehicle.

For years, VW has showcased a various concept of diesel electric hybrids vehicles. Which might give us the impression that Volkswagen dealers will soon have them in their showroom? But I think it will not happen.

The spokesperson of Volkswagen who recently said that Great Britain’s Autocar that the “hybrid diesel is still not really good business sense.” The spokesman continued by saying, “the higher cost of clean diesel technology will make them even more expensive than gasoline-electric cars. The markets where the hybrid cars are most well-known are also the place where diesels are least well-known.

Keep in mind their business reality when you see a diesel electric hybrids concept car at the show.

At the same time, do not expect Volkswagen and others to stop showing of diesel electric hybrids combo, as they did in the year 2008 when it introduced the Golf TDI Hybrid concept and its 69 mpg at the Geneva Motor Show. Several months later, the green car fans are really in the foam about the possibility of plug-ins Golf Twin Drive diesel electric hybrids with lithium-ion batteries.

Or, how about last year at the Frankfurt show with the unveiling of the bullet-shaped L1 diesel electric hybrids that dished out a whopping 157.8 miles per gallon, had a top speed of 100 mph and an “impressive” driving range of 416 miles. And that wasn’t all. Three month later in Los Angeles, VW took the wraps off the Up! Lite, a three-door, four-passenger city car with a diesel hybrid system capable of 70 mpg on the highway.

Of course, we wondered why VW placing all the time, money and engineering resources to develop this concept vehicle, when not long after the Golf TDI Hybrid Concept was revealed in 2008, the company cited in Auto, Motor und Sport that they will not build car because it would be “too expensive.”

Oh well. That’s show business.
