DETROIT – General Motors Maven car-sharing program will soon include peer-to-peer vehicle rentals, Marketing Daily reports. Peer Cars is being tested in Chicago, and Ann Arbor and Detroit, Michigan. The new program will allow owners and certain lessees to rent their personal Buick, Cadillac, Chevrolet or GMC car or truck model year 2015 or newer.

The on-demand mobility-sharing service Maven provides rentals of GM brand compacts, SUVs and electric vehicles by the hour, day, week or month. Peer Cars will operate much as Airbnb does for homeowners through the Maven app.

Maven has handled 180,000 reservations for more than 300 million miles driven, with vehicles insured through GM and driving members vetted prior to using the service. Maven will be looking at data from the beta test ahead of expanding Peer Cars to other U.S. locations this fall, according to Julia Steyn, vice president of General Motors urban mobility and Maven.

The car-sharing program was designed for urban environments or university campuses. Maven Gig provides car rentals by the week for delivery and rideshare drivers.

Peer Cars does have competition in the form of Turo, which has a presence in 5,500 cities across the globe with around 7 million members and more than 250,000 car rentals. “To have a big player like GM invest in the space gives validation to the work we are doing,” said a Turo spokesperson. “That said, we feel we have a pretty good advantage, and a big head start in building the marketplace.”
