Opting for the fuel-efficient diesel version of some cars or trucks could save you a lot of money.
Or not at all. Vincentric, a company that specializes in assessing total cost of ownership, just made those calculations, and found that diesels as a whole cost more over the long run (considering five years of ownership and 15,000 miles of driving per year) than the market-equivalent gasoline versions of the same model.
Over 35 vehicles that are available in gasoline and diesel form, the firm found just eleven models for which the cost of ownership was lower compared to the gasoline counterpart. Furthermore, the average cost of ownership for diesels is anticipated at $2,754 higher than their gasoline counterpart. That’s up $1,737 compared to the last time Vincentric performed this study in November 2013.
Pump price on diesel not dropping as steeply as gasoline
The sometimes shocking initial price premium for diesels—market-wide, an average $5,390—proved an insurmountable barrier toward long-term payoff in some models. Meanwhile, gas prices are down, while pump prices for diesel haven’t been falling at quite the same rate.
As of this week, U.S. average pump prices for regular-grade gasoline are at about $2.55 per gallon; diesel prices stand at $3.42 per gallon. And in general, higher refining and distribution costs for U.S. pump diesel mean that it likely won’t fall, proportionately, as much at the pump due to the sustained low price of crude oil.
But going with the diesel version likely does pay off if you’re considering it on a luxury model. Of all the vehicles for which Vincentric found diesel at an advantage, all but one were German luxury-brand models. Mercedes-Benz in particular ended up posting plenty of diesel deals because of a strategy that makes its BlueTec diesel models the ‘entry’ models in several of its vehicle lineups.
Diesel pays off for luxury but not mainstream models?
The Ram ProMaster Diesel 1500 is the only mainstream-brand diesel model that managed to make the cut in offering a cost-of-ownership savings over five years. Surprisingly, ‘TDI’ diesel versions of the the Volkswagen Golf, Jetta, Passat, and Beetle didn’t make the cut; neither did the VW Touareg SUV or the Chevrolet Cruze Diesel sedan. Diesel versions of full-size pickups from Chevrolet, GMC, Ford, and Ram also didn’t show a payoff for going diesel.
Vincentric’s calculations factor in a wide range of costs well beyond fuel cost—things like insurance premiums, and estimated maintenance expenses.
