It’s cheaper to drive a diesel-powered vehicle than a gas-powered vehicle over the course of three to five years, according to a new study commissioned by Robert Bosch LLC – a company that makes plenty of diesel engine parts – using data compiled by The University of Michigan Transportation Research Institute. The savings stem not just from improved fuel efficiency but also overall fuel costs and better retention of value, and take into account the added purchase price of a diesel engine over its gasoline counterpart.
According to the study, “most of the savings are in the $2000 to $6000 range.” The highest return on investment comes from the Mercedes-Benz GL-Class. Buyers of a diesel GL will save a shocking $13,514 over the course of three years and $15,619 in five. Another star performer is the Volkswagen Golf TDI, which can save its owner more than $5,000 over three years.
