Diesel Vs. Electric: Why Diesel Cars Still Outperform In 2023

why diesel cars are better than electric cars

Diesel cars offer several advantages over electric vehicles, particularly in terms of range, refueling convenience, and infrastructure availability. Unlike electric cars, which often require hours to charge and have limited driving ranges, diesel vehicles can travel significantly farther on a single tank of fuel, making them more suitable for long-distance travel. Additionally, the widespread availability of diesel fueling stations ensures that drivers are less likely to face range anxiety or struggle to find a place to refuel. Diesel engines also tend to be more durable and require less maintenance compared to electric powertrains, providing long-term reliability. Furthermore, diesel technology has advanced to reduce emissions, addressing environmental concerns while maintaining the efficiency and power that make diesel cars a practical choice for many drivers.

Longer Range: Diesel cars offer greater driving range per fuel fill compared to electric vehicles

One of the most compelling advantages of diesel cars over electric vehicles (EVs) is their superior driving range per fuel fill. A typical diesel car can travel between 600 to 1,000 miles on a single tank, depending on the model and driving conditions. In contrast, even the most advanced EVs struggle to exceed 400 miles on a full charge, with many models averaging around 250 to 300 miles. This disparity becomes particularly significant for long-distance travel, where diesel vehicles offer uninterrupted journeys without the need for frequent stops. For instance, a diesel-powered Volkswagen Passat can cover over 800 miles on a single tank, while a Tesla Model 3 Long Range, one of the top-performing EVs, maxes out at approximately 360 miles.

Consider the practical implications of this range difference. A family planning a 700-mile road trip in a diesel car could complete the journey with just one fuel stop, assuming a 1,000-mile range. In contrast, the same trip in an EV would require at least two charging stops, each lasting 30 to 60 minutes, depending on the charging station’s speed. This not only extends travel time but also introduces uncertainty, as public charging infrastructure remains inconsistent in many regions. For drivers who prioritize efficiency and convenience, diesel’s longer range provides a clear edge, especially in areas where charging stations are scarce or unreliable.

From an analytical perspective, the energy density of diesel fuel plays a critical role in this range advantage. Diesel contains approximately 35.8 megajoules per liter, compared to the 0.1 megajoules per kilowatt-hour (kWh) of lithium-ion batteries commonly used in EVs. This means diesel fuel packs significantly more energy into a smaller, lighter package, enabling vehicles to travel farther without the added weight of larger batteries. While battery technology continues to improve, it has yet to match the energy density of diesel, making it a limiting factor for EV range. Until breakthroughs in battery efficiency occur, diesel’s inherent energy advantage will remain a key differentiator.

For those considering a switch from diesel to electric, it’s essential to weigh the trade-offs carefully. While EVs offer environmental benefits and lower operating costs, their limited range can be a deal-breaker for certain lifestyles. If your daily commute is under 100 miles, an EV might suffice, but for frequent long-distance travelers, diesel remains the more practical choice. To maximize efficiency, diesel drivers can adopt habits like maintaining steady speeds, avoiding rapid acceleration, and ensuring proper vehicle maintenance, which can further extend range. Conversely, EV owners must plan routes meticulously, factoring in charging times and station availability, which can add complexity to travel.

In conclusion, the longer range of diesel cars provides a tangible benefit that addresses a critical pain point for drivers: the ability to travel farther without interruption. While EVs have made strides in range and infrastructure, they still fall short of diesel’s capabilities, particularly for extended journeys. For consumers who value reliability and convenience, diesel’s range advantage remains a strong argument in its favor, making it a superior choice in scenarios where distance and efficiency are paramount.

Faster Refueling: Diesel refueling takes minutes, while electric charging can take hours

One of the most tangible advantages of diesel cars over electric vehicles (EVs) is the stark difference in refueling times. Filling a diesel tank typically takes 5 to 10 minutes, a process so quick it can be completed during a short break. In contrast, charging an electric car, even with fast chargers, can take anywhere from 30 minutes to several hours, depending on the battery size and charging infrastructure. For drivers on tight schedules or long trips, this disparity is not just an inconvenience—it’s a deal-breaker. Imagine stopping for coffee while refueling your diesel car versus planning an extended lunch break just to charge your EV. The math is simple: diesel refueling aligns with the pace of modern life, while electric charging often demands patience and foresight.

Consider the practical implications for long-distance travel. A diesel car can cover 600 to 800 miles on a single tank, and refueling stops are brief and predictable. Electric vehicles, even with advanced batteries, often have a range of 250 to 350 miles per charge, and finding a fast charger en route can be hit or miss. For instance, a family driving from Los Angeles to Las Vegas (270 miles) in an EV might need to stop for at least 45 minutes to recharge, assuming a fast charger is available. In a diesel car, the same trip would require no stops, or at most a 10-minute refueling pause. This efficiency makes diesel cars more reliable for spontaneous or time-sensitive journeys.

The refueling time advantage of diesel cars also stems from the maturity of their infrastructure. Gas stations are ubiquitous, with diesel pumps readily available in urban and rural areas alike. In contrast, the EV charging network is still expanding, with fast chargers often concentrated in cities or along major highways. For diesel drivers, refueling is a seamless part of their routine, whereas EV owners must plan their routes around charging stations, adding complexity to their travel. This disparity is particularly pronounced in regions with limited charging infrastructure, where diesel cars maintain a clear edge in convenience.

Critics of diesel cars often point to environmental concerns, but the refueling speed argument remains a practical, immediate benefit. For drivers prioritizing time efficiency, diesel’s quick refueling process is a decisive factor. Until EV charging times are reduced significantly or infrastructure becomes as widespread as gas stations, diesel cars will continue to offer a faster, more predictable refueling experience. For those who value their time and flexibility, this alone can tip the scales in favor of diesel.

Established Infrastructure: Diesel stations are widely available, unlike limited EV charging networks

One of the most immediate advantages of diesel cars lies in the established infrastructure that supports them. With over 150,000 gas stations in the U.S. alone, diesel fuel is readily available in nearly every corner of the country. This contrasts sharply with the current state of EV charging networks, which, despite rapid growth, remain limited in both quantity and accessibility. For instance, a 2023 report by the International Energy Agency highlights that there are only about 130,000 public EV charging stations globally, many of which are concentrated in urban areas. This disparity means diesel drivers can embark on long journeys with confidence, knowing refueling is rarely more than a few miles away.

Consider the practical implications for a family planning a cross-country road trip. A diesel car, with its average range of 500–700 miles per tank, allows for seamless travel, requiring only brief stops every 8–10 hours. In contrast, an EV driver must meticulously plan their route around charging stations, factoring in the 30–60 minutes needed for a fast charge—a process that can disrupt schedules and add hours to travel time. For example, a Tesla Supercharger, while efficient, is still not as ubiquitous as diesel stations, particularly in rural areas. This logistical challenge underscores the reliability of diesel infrastructure for long-distance travel.

From a comparative standpoint, the density of diesel stations offers not just convenience but also peace of mind. A diesel driver in a remote area can rely on the likelihood of finding fuel within a reasonable distance, whereas an EV driver may face range anxiety due to the scarcity of charging options. Take the example of a rural highway in Montana, where diesel stations are often spaced every 50–100 miles, compared to EV chargers, which may be nonexistent for stretches of 200 miles or more. This gap in infrastructure highlights why diesel remains the more practical choice for drivers in less populated regions.

To illustrate further, imagine a scenario where a diesel and an EV driver both need to refuel in a small town. The diesel driver pulls into a local station, refuels in under five minutes, and continues their journey. The EV driver, however, must locate a charging station, which may be miles away, and then wait for at least 30 minutes to regain sufficient range. This example demonstrates how the established diesel infrastructure not only saves time but also reduces the stress associated with refueling.

In conclusion, the widespread availability of diesel stations provides a tangible advantage over the still-developing EV charging network. While electric vehicles offer environmental benefits, their practicality is hindered by infrastructure limitations. For drivers prioritizing reliability, convenience, and the ability to travel without constraints, diesel cars remain the superior choice—at least until EV charging networks achieve comparable accessibility.

Lower Upfront Cost: Diesel cars are generally cheaper to purchase than electric vehicles

For budget-conscious buyers, the sticker price remains a decisive factor. Diesel cars consistently undercut electric vehicles (EVs) in upfront cost, often by thousands of dollars. A mid-range diesel sedan, for instance, can be purchased for around $25,000–$35,000, while a comparable EV with similar features and range typically starts at $35,000–$45,000, even after federal tax incentives. This price gap widens further in the luxury segment, where diesel SUVs and sedans offer premium amenities at a fraction of the cost of their electric counterparts. For families or individuals prioritizing immediate affordability, diesel’s lower entry point makes it a pragmatic choice.

However, this cost advantage isn’t just about the initial purchase. Diesel vehicles also benefit from a mature, established market, meaning depreciation rates are more predictable and resale values tend to hold better than those of newer EV models. A three-year-old diesel car, for example, might retain 50–60% of its original value, whereas an EV of the same age could depreciate by 40–50% due to rapid technological advancements in battery technology. This makes diesel a safer bet for those concerned about long-term financial stability.

Critics argue that lower upfront costs ignore the total cost of ownership, but for many drivers, cash flow constraints dictate decisions. A diesel car’s affordability allows buyers to allocate savings to other financial priorities, such as home repairs or education. Additionally, diesel’s simpler drivetrain and fewer high-tech components often translate to lower maintenance costs compared to EVs, which may require specialized repairs for complex battery systems or electric motors.

To maximize the value of a diesel purchase, consider opting for models with proven reliability, such as the Volkswagen Golf TDI or Toyota Hilux diesel. Pairing this with regular maintenance—like oil changes every 10,000 miles and fuel filter replacements every 20,000 miles—ensures longevity and minimizes unexpected expenses. While diesel may not be the future, its present-day affordability and practicality make it a compelling option for those unwilling or unable to pay a premium for electric technology.
