We recently published a study to find if buying a hybrid car is worth it and the price per mile on an EV. While the initial price of the hybrid trim is more expensive than a non-hybrid, the savings with superior fuel economy pays off in the long run, right? The results were surprising and it got us thinking if diesel cars are really worth the extra coin.
We conducted this study in a similar fashion to the hybrid study. We found models available with both diesel and traditional unleaded gasoline engines, equipped them comparably and then found the difference in MSRP. We calculated how many miles someone would have to drive a diesel car for the savings in fuel consumption to outweigh the increased price. The only real difference between the two studies is accounting for the cost of diesel fuel. [keep reading]
