Study claims diesel vehicles are cheaper to own

A new survey has been published looking at the cost of ownership for gasoline vehicles compared to diesel vehicles. The University of Michigan conducted the study for Robert Bosch, LLC.

The study determined that diesel vehicles save owners between $2,000 to $6,000 in total ownership costs during a 3- to 5-year period compared to similar gasoline vehicles. The data was compiled by the University of Michigan Transportation Research Institute.

"Overall, the results of our analyses show that diesel vehicles provide owners with a TCO (total cost of ownership) that is less than that of the gas versions of the same vehicles," according to the study. "The estimates of savings for three and five years of ownership vary from a low of $67 in three years to a high of $15,619 in five years.”

The study claims that Volkswagen Jetta owners saved $3,128 while Volkswagen Golf owners saved an estimated $5,013 compared to owners of similar gasoline-powered vehicles. The study also finds that all of the diesel vehicles had better miles per gallon figures then gasoline versions with diesel is offering between 8% and 44% higher fuel economy.

The study also shows that nine of the 10 diesel vehicles held their value better the comparable gasoline vehicles.
 
One has to keep in mind, however, that Bosch has quite a big financial stake in these results as it produces high-pressure fuel pumps for diesel manufactures like Volkswagen which have a tendency for failing in late model vehicles.

I think that's what makes the study valid. If you push the dates out it gets more interesting but harder to determine since once parts start failing it's hard to keep comparing information. Bare minimum over what should be the most reliable period of a vehicle's life, is a diesel still worth it? This says yes.

As you aluded to, most diesel owners also buy them for the longevity they have been known for, and that's a different animal. Diesel repairs can get very expensive very quick, it would be interesting to see how that advantage holds up over longer periods of time, but there are so many variables it would be impossible to really compare the two to the point no one could cry foul.
