What is Car Sharing?

Car sharing is a service that provides members with access to a fleet of vehicles on an hourly basis. Once you become a member (by completing the application process), you can choose to reserve any car you like, in advance, and drive it for as long as you need!

Use your reservation time to run your daily errands. Go grocery shopping at your favorite market, visit a friend across town, or take a client out to lunch. Show your commitment to GREEN transportation solutions while doing the things you do everyday, but now in an altcar.

Rates start as low as $7.50 per hour and include Gas (in this case electricity), Premium Auto Insurance, and Maintenance.

Membership is just around the corner!

Follow these three simple steps:

  1. Make sure car sharing is right for you and that you are eligible for enrollment.
  2. Choose your membership type and fill out the application –
  3. Complete the online orientation for new members. After applying you'll be taken to a short orientation that explains how the system works.

Reserve (24/7):

Registered altcar members can reserve an altcar vehicle through our website or contact an altcar representative via telephone for help. Reservations are generally made on an hourly basis, with daily reservations as an option. Our fleet is parked in spaces that are reserved only for our vehicles. Currently our fleet is located at the Maryland Science Center (Inner Harbor). As we grow you will be able to choose from a variety of vehicles at different locations with various amenities.


altcar car-sharing members will be given an electronic membership card that will grant them access to a vehicle at the time of rental. All you have to do is swipe the card across the card reader, and the GPS enabled system will recognize your reservation and unlock the doors. The vehicle keys will be stored inside the car for easy access (check the glovebox).


Use your altcar to run errands, visit friends, or anything else around town. Once finished, just park the vehicle back in the same parking spot you reserved it from. (No one else is allowed to park in your designation parking location) And swipe your card again over the reader to end your reservation.

Benefits to Baltimore

Car-sharing is a service that is great for the environment. It is designed to reduce traffic, reduce parking congestion, Reduce Green House Gas (GHG) emissions and provide freedom of mobility to people who do not own cars.

altcar takes this philosophy a bit further, as our fleet is made up of 100% electric vehicles!

Did I read that right? 100% electric?

Yes, altcar is the first fleet of Lithium Ion Powered electric vehicles to be used in a car sharing operation in the United States. Our vehicles drive much like traditional automobiles, except they have zero emissions. Currently our vehicles are City Cars*, which means they can not travel on streets with posted speed limits above 35mph, but that is okay, because 95% of Baltimore’s roadways are within this range. Stay tuned, as we will be bringing Highway capable electric vehicles to our fleet in the coming months.

As our membership grows, we will continue to grow our fleet. Our promise to you and the environment, is that we will only use the cleanest most fuel efficient vehicles available. So expect to see either 100% Electric altcar’s, Plug-In Hybrid altcars, and whatever new technology is around the corner.
