Diesel vehicles are often touted for their superior fuel efficiency, but is that enough to make them a better financial choice compared to their gasoline counterparts? This article delves into the various factors that influence the cost of owning a diesel vehicle, including purchase price, maintenance, insurance, and depreciation. We also provide interesting statistics and insights that are often overlooked.
Diesel engines are renowned for their fuel efficiency. According to the U.S. Department of Energy, diesel engines can achieve 20-35% more miles per gallon than their gasoline counterparts (source). This translates to significant fuel savings over the life of the vehicle. For instance, a diesel vehicle that gets 30 miles per gallon (mpg) compared to a gasoline vehicle that gets 20 mpg can save approximately $750 annually, assuming an average of 15,000 miles driven per year and a fuel cost of $3 per gallon.
While diesel vehicles offer better fuel economy, they often come with a higher upfront cost. According to Vincentric, a research firm specializing in vehicle ownership costs, diesel vehicles can be $2,000 to $5,000 more expensive than their gasoline counterparts (source). However, diesel vehicles tend to depreciate more slowly. On average, diesel vehicles retain 63% of their value after three years, compared to 53% for gasoline vehicles (source).
Diesel engines are more complex and require specialized maintenance, which can be more expensive. For example, modern diesel engines use a urea-based solution to reduce emissions, adding to the maintenance costs. According to AAA, the average annual maintenance cost for a diesel vehicle is about $1,200, compared to $900 for a gasoline vehicle (source). Additionally, insurance premiums for diesel vehicles can be slightly higher due to their higher replacement costs.
Modern diesel engines are equipped with advanced emissions control technologies, making them cleaner than older models. The use of urea-based solutions helps neutralize harmful emissions, making diesel vehicles comparable to gasoline vehicles in terms of environmental impact. According to the Environmental Protection Agency (EPA), new diesel vehicles emit 10-20% less CO2 compared to gasoline vehicles (source).
The Mercedes-Benz GL350 Bluetec is a prime example of a diesel vehicle offering significant savings. According to Vincentric, the GL350 Bluetec has a five-year ownership cost that is $4,750 less than the gasoline-powered GL450 4Matic. Despite a purchase price that is only $101 higher, the fuel savings and lower depreciation make the GL350 Bluetec a more economical choice.
The BMW S350 Bluetec 4Matic is another diesel vehicle that stands out. It is the least expensive S-Class model and offers all-wheel drive, unlike its gasoline counterparts. The S350 achieves an impressive 25 mpg overall, with 21 mpg in the city and 31 mpg on the highway. Over five years, the S350 Bluetec saves approximately $4,003 in fuel costs compared to its gasoline equivalent.
While diesel vehicles come with higher upfront costs and potentially higher maintenance and insurance expenses, their superior fuel efficiency and slower depreciation can make them a more economical choice in the long run. However, the decision to opt for a diesel vehicle should be based on individual driving habits, fuel prices, and maintenance capabilities.
By considering these factors, you can make a more informed decision about whether a diesel vehicle is the right choice for you.
