Nothing like a little rental income to help make the monthly payment on the Caddy, huh?

General Motors, which said last fall that it reached an agreement with RelayRides to make people's personal vehicles available for car sharing, is doing just that. Tuesday, GM said that owners of cars equipped with the automaker's OnStar navigation service can rent out the vehicles to RelayRides subscribers. Through the service, RelayRides members can now use their smartphones to unlock participating GM vehicles. Subscribers can also get access to the cars by replying to certain text messages. GM says its vehicle owners may be able to earn "hundreds of dollars per month from their idle vehicles."

RelayRides debuted its peer-to-peer car-sharing service in Boston two years ago and took the service nationwide earlier this year. GM reached its agreement with RelayRides last fall, saying at the time that all GM vehicles built after 2010 and equipped with OnStar would be ready for the service.

RelayRides and OnStar: Baby, You Can Rent My Car
Millions of subscribers can instantly access nationwide peer-to-peer car sharing market


DETROIT – General Motors' OnStar subscribers can now rent out their idle vehicles through the RelayRides marketplace, leveraging OnStar connectivity already active in their vehicles to potentially earn hundreds of dollars a month to offset the cost of owning a vehicle.

RelayRides' renters can unlock reserved OnStar-enabled cars simply by using their smart phones. RelayRides is the first third-party developer to integrate with GM OnStar's proprietary application program interface (API) that will be available to other developers later this summer.

OnStar's connectivity solution provides RelayRides' members with increased security, reliability and accessibility. Individuals who forgo car ownership can conveniently access affordable and reliable transportation in a Chevrolet, Buick, GMC, or Cadillac. Owners of these OnStar-enabled GM vehicles rent out their cars and turn their idle vehicles into an income source without the hassle of installing expensive aftermarket hardware or having to meet a renter to hand off keys.

"General Motors, through OnStar, and RelayRides have joined forces to create an entirely new mobility solution for U.S. drivers interested in more affordable, sustainable and collaborative automobile options," said Nick Pudar vice president OnStar Strategy and New Business Development. "Our exclusive relationship with RelayRides provides an exciting new choice: the first automobiles to run on collaborative consumption."

Through OnStar's proprietary API, RelayRides developers were given access to key vehicle-centric features such as location and remote door lock and unlock. This means renters can unlock the doors with their smart phone or by replying to a text message. Depending on location and availability of the car, RelayRides marketplace participants can earn hundreds of dollars per month from their idle vehicles. Owners whose cars are not OnStar-enabled can still rent out their vehicles through the RelayRides' marketplace by exchanging keys with the renter, or reactivating their OnStar subscriptions.

OnStar services are enabled by its Advanced Telematics Operating Management System (ATOMS), which is the most powerful automotive cloud platform in the market today and connects about 6 million OnStar customers globally. Later this summer, OnStar will make its proprietary API available to third-party developers.

Studies show that each shared car results in up to 13 fewer cars on the road, leading to less- congested roads and less pollution.

"Using the OnStar API to access GM vehicles empowers RelayRides to make car sharing even safer and more convenient," said Shelby Clark, RelayRides founder and Chief Community Officer. "The sheer number of vehicles eligible for the program allows us to greatly expand across the U.S. and introduce the economic, environmental and community benefits of car sharing to regions that car sharing services have previously been unable to serve."

RelayRides pioneered peer-to-peer car sharing when it launched in Boston in June 2010 and expanded into San Francisco later that year. In March 2012, RelayRides became the first service to launch nationwide, introducing a key-exchange program to enable renters and owners to enjoy the benefits of car sharing. Relay Rides provides all vehicle owners with a $1 million insurance policy for owners for the duration of the rental and a $300,000 policy for renters.

      Seems like an interesting idea, but I don't expect many to participate.
        • 3 Years Ago
        Agreed, I'll keep an eye out for someone who wants to rent me their ZR1 or ZL1 though.
      • 3 Years Ago
      What could POSSIBLY go wrong?

      I like the idea but it seems like there would be a lot of complications and/or restrictions. It would be nice if the owner could track the car's location and speed in real time.

      I'm sure all that extra money will be well spent on insurance deductibles and having the car detailed after they spil their Big Gulp's all over the carpet!

      So what you are telling me, is that you are using an app on your phone to allow someone to use your car, on you phone that lacks protection from the many vulnerabilities to take your information?
      • 3 Years Ago
      hey i just texted you and this is crazy, but i'm going somewhere, give me a ride maybe? (I tried my best)
      • 3 Years Ago
      Great idea, pays you back some money... but I'd imagine your insurance company will have something to say about this.

      I don't even let people I know borrow my car, let alone a perfect stranger.
      • 3 Years Ago
      Who comes up with this crap? This is such a terrible idea it's not even funny. The only people I've let drive my car have been VERY close friends and only while I've been sitting in the passenger seat.

        I'm glad you represent the entire population. Could you please offer your opinion on gay marriage and abortion so we can just clear those issues right up?
      • 3 Years Ago
      I'll bet the auto insurance industry must just love this one! "where will the car be garaged?" "no clue". "will there be anyone under 21 who has access to the vehicle?" "I don't know". "how many miles per year will you be driving?" "I don't know". priceless.

        Yeah, insurers just won't know what to do! I mean maybe if there and industry that was based around the concept of RENTING a CAR to somebody then they could work out the legal issues similar to that business but it's a shame these CAR RENTAL companies just don't exist.

      I just can't imagine anyone allowing strangers to drive their personal car. If they are so hard up for cash, why do they even have a car they don't drive anyways?
      • 3 Years Ago
      RelayRides is a great idea, though I think the critical missing element is the social networking angle; it would be best if you could put your car up for rent but only to friends or friends of friends, limiting the degrees of separation based on your preferences. The marriage of RelayRides with OnStar is the best possible pairing that a car sharing service could hope for; it takes care of three major problems with shared vehicles, namely handing the key transfer, figuring out the location of the car before and after it's used, and the security issue as well. If I had an OnStar equipped car, I'd sign up for it today!

        @waetherman does kind of cut out all non-GM vehicles...
