Nine Diesel Fuel Cars and Trucks That May Save You Money

The Economics of Diesel Vehicles

Diesel engines are renowned for their fuel efficiency, often delivering 20-30% better fuel economy than gasoline engines. However, the initial purchase price and maintenance costs can sometimes offset these savings. According to Vincentric, a research organization specializing in cost-of-ownership analysis, diesel vehicles often come with higher insurance, maintenance, and repair costs. This is partly due to the need for a urea reservoir, which injects urea into the exhaust to neutralize pollutants, a key component of modern clean-diesel technology.

Cost of Ownership Analysis

Vincentric's study examined 24 diesel vehicles available in the U.S., including 10 commercial trucks and 14 consumer cars. The analysis considered a five-year ownership period with an annual mileage of 15,000 miles. The study found that nine diesel models had lower five-year ownership costs compared to their gasoline counterparts. The factors considered in the analysis included:

• Depreciation
• Financing
• Taxes and Fees
• Fuel Costs
• Insurance
• Maintenance
• Repairs
• Opportunity Costs

The fuel price used in the analysis was a weighted national average over the past five months to reflect market trends accurately.

Notable Findings

One of the standout models in the study was the Mercedes-Benz GL350 Bluetec, which offered significant fuel savings of approximately $4,550 over five years. Despite its higher initial cost, the GL350 Bluetec's overall ownership cost was only $101 more than the gasoline-powered GL450 4Matic.

Another noteworthy model was the Mercedes-Benz S350 Bluetec 4Matic, the most affordable S-Class model in the study. It was one of the few diesel vehicles with a lower purchase price compared to its gasoline equivalent. The S350's fuel savings of $4,003 were particularly impressive, given that it is the only S-Class model with all-wheel drive.

The Hidden Costs of Diesel

While diesel vehicles offer fuel savings, they also come with hidden costs. Diesel engines are more complex and require more frequent maintenance. The urea reservoir, essential for clean-diesel technology, needs regular refilling and maintenance. Additionally, diesel vehicles often have higher insurance premiums due to their higher purchase price and repair costs.

Insurance and Maintenance

Donald Wurster, President of Vincentric, notes that diesel vehicles generally have higher insurance, maintenance, and repair costs. However, they also tend to have lower depreciation rates, which can offset some of these expenses. For example, diesel engines are known for their longevity, often lasting 30% longer than gasoline engines, which can result in lower long-term depreciation.

Conclusion

Diesel vehicles offer significant fuel savings and lower depreciation rates, but these benefits are often offset by higher initial purchase prices and maintenance costs. However, for those who drive long distances or use their vehicles for commercial purposes, the fuel savings can be substantial. The Mercedes-Benz GL350 Bluetec and S350 Bluetec are prime examples of diesel models that offer potential cost savings over their gasoline counterparts.
