In August 2019, the Bargersville Police Department introduced its first all-electric patrol vehicle, making it one of the first departments in the United States to implement the Tesla Model 3 as a squad car. Since then, three more Tesla Model 3 vehicles have been added to the department’s fleet.

For many years it was believed electric vehicles could not provide the speed, handling, and power needed in pursuit vehicles. Police Chief Todd Bertram of the Bargersville Police Department said, “That is not the case.”

Following Bargersville’s lead, the Westport Police Department in Connecticut and the Windham County Sherriff’s Office in Virginia have purchased their first Tesla vehicles.

Chief Todd Bertram and the Bargersville Police Department found the Tesla Model 3 vehicles are saving the department each month. August of 2020 marked the one-year birthday of the first Tesla Model 3 purchased by the department. Bertram reported over the course of its first year, the Tesla Model 3 saved the department $6,320 in fuel and maintenance costs in comparison to the gasoline-powered sedan the department traditionally purchases. 

The Tesla Model 3 vehicle purchase price is $14,500 more than its traditional vehicle. With the fuel and maintenance savings the department has seen over the course of the first year, the department expects to recoup its investment in just 19 months.

Over the course of the six-year span the department typically has a vehicle, each Tesla will save the department approximately $38,000. After recovering the $14,500 from the increased purchase price, the department will net approximately $23,500 for each Tesla in the fleet. With the four Tesla Model 3s currently in the department, the Bargersville Police Department is on track to save approximately $152,000 over the next six years.

The department currently has 14 patrol cars. With an all-electric police fleet, Chief Bertram hopes Bargersville will one day achieve a goal of saving more than $88,500 each year. The additional savings will go a long way for the Bargersville Police Department. Like many police departments, Bargersville has a finite budget. With the introduction of the all-electric patrol cars, the department could repurpose the dollars saved on fleet fueling and maintenance to fund other budget items without needing to increase the overall budget.

Environmental Benefits

In addition to the cost savings experienced with the addition of an electric vehicle, fleets also benefit from reduced emissions resulting in cleaner air. Each electric vehicle introduced to the Bargersville Police Department fleet reduced the carbon monoxide (CO) and nitrogen oxide (NOx) emissions by 100% compared to the conventional vehicle being replaced. Overall, the addition of four electric vehicles reduced the fleet’s NOx emissions by 28.5% and CO emissions by 28.5%.

Maintenance and Fuel Costs, Travel During COVID-19

Despite COVID-19, Chief Bertram reported the department saw an “increase in trips taken.” He went on to say, “The electric vehicles saw increased mileage and savings” during the months of March and April 2020, when the pandemic prompted a sharp decrease in travel throughout Indiana.

Overall, the department budgeted $49,000 for fuel in 2020 and by June, 75% of the department’s fuel budget was still available.

The department installed one electric vehicle charger to the side of the Police Department Building and another on town property. In total, the department spent $1,000 to install the EV chargers. Moving forward, the department hopes to expand the charging infrastructure available to six level 2 chargers and one DC Fast Charger.

Since August 2019, the department has experienced minimal maintenance related expenses for its electric vehicles. “The only time the cars have been up on a lift was to have the tires replaced,” Chief Bertram explained. The vehicles have minimal maintenance requirements, keeping the vehicles on the road and out of the shop.

Maintenance Schedule Analysis

A significant portion of the cost savings associated with EV comes from the reduction in fuel costs. However, when considering the nature of working vehicles, the maintenance cost savings are often significant over the vehicle’s operational lifetime. Analyzing the maintenance schedule of EVs reveal not only a reduction in the cost of maintenance, but a reduction in the frequency of service. This includes time spent off the road, adding to the opportunity costs of operating their gas-powered equivalents. Below is a list of the maintenance requirements and schedule from the manufacturer.

Yearly Maintenance:

Brakes: Brake pads do not require replacement due to regenerative braking. However Tesla recommends cleaning and lubricating all brake calipers every 12 months or 12,500 miles for cars in cold weather regions.

Tires – Rotation, Balance, and Wheel Alignments: Tesla recommends rotating tires every 6,250 miles or if tread depth difference is 2/32 in or greater, whichever comes first. Unbalanced and misaligned wheels affect handling, tire life, and steering components.

Scheduled Maintenance:

Cabin Air Filter: Teslas are equipped with an air filter that prevents pollen, industrial fallout, road dust, and other particles from entering through the vents. Tesla recommends replacing your cabin air filter every two years. If your Tesla is equipped with a HEPA filter, Tesla recommends replacing it every three years.

Brake Fluid Test: Tesla recommends testing brake fluid lines for contamination every two years and replacing as needed.

Air Conditioning Service: An air conditioning service replaces the desiccant to help the longevity and efficiency of the air conditioning system. Tesla recommends an air conditioning service every two years for Model S, every four years for Model X and Model Y, and every six years for Model 3.

EV Patrol Car: Myth vs Fact

Pursuit: When considering vehicles for law enforcement, pursuit and high-speed chase are often the first challenges posed by officers and police councils. When asked about the EV’s pursuit rating, chief Bertram gave a brief background of these ratings saying, “The performance is what you rate it on.” He continued to highlight a few of the specifications that set it apart from its traditional incumbent, stating, “You don’t have all of the junk that happens in a gas car.”

He recalls a pursuit early on while in the Model 3 and highlighted a few facts from the chase. “It was not a high-speed pursuit, most of them are not.” The idea that every pursuit result in a high-speed chase doesn’t reflect in his experience. “They’re trying to get away from you, they’re not trying to race you,” he said. During these types of pursuits, the EV’s instant acceleration and low volume makes it more agile in urban and suburban areas.

Range: When considering the area of operation for officers, range is often highlighted as the second biggest concern. Rural police departments often have larger jurisdictions, leading some to believe the range of an EV may cause limitations. To address the topic of range, Chief Bertram said, “When you start your shift out on an empty tank, the same thing will happen in a gas car.” He went on to say that even with the heat or air-conditioning, lights, and computer running the car could “run for days.”

When asked how the department has addressed their charging situation, Chief Bertram gave some insight, stating, “We’ve since put another charger on town property, resulting in more charging options.” With plans for a new building, the department is also factoring in more Level 2 chargers and a DC fast charging station.

Equipment: Some manufacturers offer pre-outfitted patrol vehicles that come fully equipped with traditional equipment like lighting and auxiliary power. However, in most cases, police departments purchase their vehicles without the added equipment, opting to install after the purchase. Chief Bertram remarked that its traditional vehicle is no different in that it also comes stripped down. When asked if the Tesla Model 3 had the features he needed, Chief Bertram replied, “Of course the Tesla has all of that, and it gets better over time.” This is in reference to the Tesla’s ability to improve through software updates over the air (wireless capability).

Surveillance: Over the last year, surveillance has been a priority for police departments across the country. The Tesla Model 3 is equipped with eight surround cameras that provide 360 degrees of visibility around the car at up to 250 meters of range. Not only do the built-in cameras aid in accident prevention, they have aided Chief Bertram in picking up useful footage in the field even before he has begun recording, proving invaluable to the department.

Overall, Todd Bertram has found their new electric patrol cars have “outperformed the other patrol cars” the department uses.

Advice for Fellow Departments

When asked if there were any lessons learned during his experience, Bertram said, “I’ve talked to hundreds of police departments from all over the country. People have called wanting to know how it’s going, what we did, and how we did it.”

“I’ve become a spokesperson for police Tesla adoption. Because of the savings we’ve experienced and the fact the cars have multiple capabilities, we continue to add them to our fleet,” he added. “Eventually, we would like to have an all-electric vehicle fleet.”

He expressed departments should “do their homework” when considering an electric patrol car to find out more about the vehicles, their capabilities, and the availability of charging stations in the area. Bertram said he couldn’t see how the electric cars wouldn’t work for an agency or municipality, encouraging departments interested to take a look at the available options and test drive an electric car to see for themselves.
