On the Lookout for Diesel-Engined Cars and Trucks That Can Save You Money

The Diesel Advantage: Fuel Efficiency and Beyond

Diesel engines are renowned for their superior 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 efficiency translates to significant savings at the pump, especially for high-mileage drivers.

The Hidden Costs of Diesel Ownership

However, the initial purchase price of diesel vehicles is often higher. For instance, the average diesel vehicle costs about $5,000 more than a comparable gasoline vehicle (source). Additionally, diesel engines require a urea tank for emissions control, which adds to maintenance costs. This urea, often referred to as Diesel Exhaust Fluid (DEF), needs to be refilled periodically, adding another layer of expense.

Maintenance and Insurance

Diesel engines are more complex and can be more expensive to maintain. According to Vincentric, a company specializing in cost-of-ownership analysis, diesel vehicles generally have higher insurance and maintenance costs. Vincentric's research indicates that diesel vehicles can have maintenance costs up to 10% higher than their gasoline counterparts (source).

Depreciation and Resale Value

One often overlooked aspect is depreciation. Diesel vehicles tend to depreciate at a slower rate compared to gasoline vehicles. However, because they are more expensive initially, the total dollar amount lost to depreciation can be higher. Vincentric's analysis shows that while diesel vehicles have a lower percentage depreciation, the absolute dollar amount can be greater due to the higher initial cost.

Case Studies: Diesel vs. Gasoline

Vincentric analyzed 12 diesel vehicles, comparing their five-year ownership costs to their gasoline counterparts. Here are some notable findings:

Mercedes-Benz GL350 Bluetec

The Mercedes-Benz GL350 Bluetec stands out with significant fuel savings. Over five years, it can save approximately $4,700 in fuel costs compared to its gasoline counterpart, the GL450 4Matic. Despite a slightly higher purchase price, the overall savings make it a compelling option.

BMW 328d

The BMW 328d is another example where diesel proves advantageous. It offers a combined fuel economy of 36 mpg, compared to 26 mpg for the gasoline-powered 328i. Over five years, this translates to substantial fuel savings, making the 328d a cost-effective choice despite its higher initial cost.

Volkswagen Golf TDI

The Volkswagen Golf TDI is known for its excellent fuel efficiency, achieving up to 43 mpg on the highway. Over five years, it can save owners around $3,000 in fuel costs compared to the gasoline-powered Golf. However, potential buyers should be aware of the higher maintenance costs associated with diesel engines.

Lesser-Known Facts About Diesel Vehicles

1. Global Popularity: While diesel vehicles make up only about 3% of the U.S. market, they account for nearly 50% of the market in Europe (source).
2. Longevity: Diesel engines are known for their durability and can often last 30% longer than gasoline engines (source).
3. Torque Advantage: Diesel engines produce more torque, making them ideal for towing and heavy-duty applications.

Conclusion

While diesel vehicles offer impressive fuel efficiency and potential long-term savings, they come with higher initial costs and maintenance expenses. It's essential to consider these factors and conduct a thorough cost-benefit analysis before making a decision. For those who drive long distances or require a vehicle with high torque, diesel can be a worthwhile investment.
