How Much Do You Save on Gas with a Tesla: Analyzing Electric Vehicle Economy

The shift from traditional gasoline vehicles to electric vehicles (EVs), such as those manufactured by Tesla, has introduced a new discussion about the cost-effectiveness of driving on electricity versus gasoline. Potential Tesla owners often weigh the initial investment against the long-term savings on fuel. While the savings can vary based on individual driving habits and local electricity rates, driving a Tesla often results in significant reductions in what drivers would typically spend on gas. Tesla’s electric vehicles are designed to be more energy-efficient than conventional gas cars, leading to lower per-mile fuel costs over time.

In the United States, the average driver covers approximately 14,263 miles per year. This driving pattern, when applied to a traditional internal combustion engine (ICE) vehicle with an average fuel economy of 24.9 miles per gallon at the 2011-2021 average gas price of $3.15 per gallon, presents a certain annual cost for fuel. In contrast, Tesla’s Model 3, which is one of the most popular models, exhibits different economics due to its electric nature. Electricity as a “fuel” for EVs like Tesla can be considerably cheaper on a per mile basis when compared to the costs associated with gasoline.

These savings can become even more apparent over time and with increasing mileage. A Tesla Model 3 owner, for example, can save a substantial amount of money in fuel costs over the course of several years. It’s important to consider, however, that actual savings can be influenced by factors such as the cost of electricity, which varies by region, and the driver’s access to home or public charging facilities. Despite these variables, the trend is clear: Tesla and other electric vehicles offer an opportunity for substantial fuel savings compared to traditional gas cars, reflecting their growing appeal as a cost-effective and environmentally friendly alternative.

Assessing Electric vs Gas Vehicle Costs

In evaluating the total cost of ownership between electric vehicles (EVs) such as Teslas and traditional gas vehicles, it’s important to consider not just the initial purchase price but also long-term expenses including fuel, electricity, and maintenance costs.

Purchase Price and Resale Value

The purchase price of electric cars, including various Tesla models, often presents a higher upfront cost, known as sticker shock, compared to similarly sized gas vehicles. However, EVs, especially high-end models, have been observed to hold their value over time, supported by data from Kelley Blue Book (KBB). Moreover, while mainstream electric cars were once priced significantly higher than gas vehicles, incentives and tax credits can reduce the difference, making EVs, such as Tesla, increasingly competitive.

Fuel Costs and Electricity Savings

When it comes to operation, the fuel cost for gas vehicles is subject to fluctuating gas prices. In contrast, electric cars require electricity for charging, and electricity costs tend to be more stable. Data shows a notable difference in the cost to charge an EV compared to the gasoline never purchased for driving the same number of miles. Tesla vehicles, noted for their energy efficiency and charging efficiency, can amplify these fuel savings, particularly when average price per kWh of electricity is compared to the equivalent cost per mile for gas vehicles.

Efficiency and Energy Consumption

Electric vehicles convert over 60% of the electrical energy from the grid to power at the wheels, while internal combustion engine (ICE) vehicles only convert about 20% of the energy stored in gasoline. This means Teslas and other EVs typically provide more miles driven per unit of energy consumption compared to gas vehicles. Their higher MPG equivalent, measured in miles per gallon of gasoline-equivalent (MPGe), showcases the increased energy efficient nature of electric cars, making them more cost-effective in terms of energy consumption over the range they can travel.

Ongoing Ownership Advantages

Owning a Tesla, like the popular Model 3 or the capacious Model X, presents a set of advantages that extend far beyond initial purchase, influencing both the wallet and the environment positively. These benefits include reduced maintenance needs as well as savings on fueling—qualities inherent to electric vehicles (EVs).

Maintenance and Repair Costs

Electric cars, including the Tesla Model S, typically require less maintenance than their gas-guzzling counterparts. This is due to having fewer moving parts to wear out or need replacement. For example, regenerative braking results in less brake wear. Tesla’s reduced service costs over time are supported by Consumer Reports, indicating ongoing financial advantages.

Typical Maintenance Costs:

  • Tesla Model 3: Lower maintenance requirements due to minimal mechanical complexity.
  • Comparative Gas Vehicle: Higher maintenance needs with engine oil, transmission fluid, exhaust systems, and more.

Public Charging and Home Charging Options

Tesla owners have access to a variety of charging options, including an extensive Supercharger network and the convenience of at-home charging. Public charging can vary in cost, with Supercharging being more expensive than home charging. However, the overall electricity cost for charging an EV remains substantially lower than the cost to fill up a traditional internal combustion engine vehicle.

  • Public Supercharging: Quick but typically more costly than home charging.
  • At-Home Charging: Slower but cost-effective, especially if using off-peak electricity rates.

Tax Incentives and Environmental Benefits

Purchasing a Tesla can lead to tax advantages, like federal income tax incentives, which can be up to $7,500, as mentioned in this CleanTechnica article, and vary depending on the model. Additionally, EVs contribute to environmental sustainability as they emit no tailpipe pollutants and can utilize clean, green energy sources.

  • Federal Tax Incentives: Up to $7,500, potentially more with state rebates.
  • Environmental Impact: Zero emissions during operation, leading to a cleaner and greener environment.
