Why choose an EV?

  • Environmental Benefits

    Fewer CO2 emissions than gas-powered vehicles

  • Fuel Savings

    On average save $1,000 per year on fuel cost*

  • Maintenance Savings

    Only tires and windshield wipers for fully electric EVs

  • Tax Incentives

    Get up to $7,500 in federal tax credit for qualifying EV models

  • Easy Charging

    Plug in at home or at one of the many public chargers

  • More Storage

    No engine means more storage space in the frunk

  • Safety

    Small electric motors allow for car designs with larger crumple zones

*Significant additional savings can come from a reduction in maintenance costs as EVs do not require oil changes and have far fewer moving parts.

EV Maintenance

  • Maintaining an EV could not be easier. In addition to saving money on things like oil changes, tune ups, brake replacements and fluid flushing, you’ll save time. EVs typically require less maintenance than conventional vehicles because:
    • The battery, motor, and associated electronics require little to no regular maintenance
    • There are fewer fluids, such as engine oil, that require regular maintenance
    • Brake wear is significantly reduced due to regenerative braking
    • There are far fewer moving parts relative to a conventional gasoline engine.
  • The most regular maintenance you’ll be required to do with an electric car is replacing the windshield wipers and tires.

EV vs. Hybrid

Learn about the differences between a fully electric car and a hybrid electric car.
Plug-In Hybrid Electric Vehicles (PHEVs) Fully Electric Vehicles (EVs)
Powered by batteries until the energy is depleted, and then they switch to gas power. Powered solely by batteries.
Require oil changes and other combustion engine-related maintenance. Do not have a combustion engine, reducing maintenance and increasing storage capacity.
Can travel anywhere from 10 to 53 miles solely on their battery. There are no tailpipe emissions.
Have enough range for the average American's commute so most daily driving would be electric, and the combustion engine allows flexibility for long-distance travel. Some cars can travel from 150 up to 335 miles on a single charge, depending on the model.
Using regenerative braking, the car can recharge the batteries instead of wearing down the brake pads when braking. Using regenerative braking, the car can recharge the batteries instead of wearing down the brake pads when braking.
Batteries are charged by plugging the car into a standard electrical outlet or charging station. Batteries are charged by plugging the car into a standard electrical outlet or charging station.
Are eligible for the federal tax credit up to $7,500, depending on battery size. Are eligible for the full $7,500 federal tax credit.

Charging Options

Level 1: Standard Wall Outlet (120 Volt)

  • Up to 5 miles of range per hour
  • No installation required – every EV will come with a standard Level 1 charger that you plug into the wall
  • Best used for overnight charging and low-mileage daily driving – a good option for plug-in hybrid vehicles because of their smaller batteries
  • J1772 connector or Tesla connector (comes with vehicle)

Level 2: 240-Volt Outlet (Dryer Plug)

  • Average of 25 miles of range per hour
  • Often found in public areas (rest areas, shopping centers, restaurants, etc.)
  • Option to purchase and have it installed by a qualified electrician – can be either hardwired or plugged into an existing 240-volt outlet (dryer plug)
  • Best for quick charging – can get a full charge from empty overnight (8-10 hours)
  • J1772 connector or Tesla connector (comes with vehicle)

DC Fast Charging

  • Fastest EV charging option – provides up to 250 miles of range per hour, depending on the car and charging equipment
  • Can charge up to 80% typically in about 20-30 minutes
  • Used to facilitate longer distance driving or road trips or for a quick recharge
  • Most non-Tesla chargers have a CCS/SAE Combo connector
  • Tesla DC fast chargers will only work with Tesla vehicles

Tax Incentives

There is a federal tax credit of up to $7,500 for buying a new electric car. Once the car manufacturer reaches 200,000 EVs sold, the tax credit is halved for the next two quarters, then halved again for the two following quarters before expiring. Plug-in hybrids can receive a smaller credit depending on their battery size, while fully electric EVs receive the full credit. For more info, visit the U.S. Department of Energy’s Tax Credit website.
