GM Tests Car-Sharing in Manhattan, Taking Aim at Zipcar and Uber
David Welch / Bloomberg Business :
Context & Ripple Effects
This 2015 Manhattan pilot is the seed of what GM would formalize months later as Maven, the brand unifying its City, Residential, Campus, and German peer-to-peer sharing operations into one car-sharing business. Starting in Manhattan — the densest, most contested U.S. market for short-term car access — put GM directly against Zipcar's established model and Uber's on-demand network rather than testing in easier secondary cities.
The arc that follows is striking: within a year Maven had scaled to nine U.S. markets including San Francisco (its ninth-market expansion), and by late 2016 the rival relationship flipped — Uber partnered with Maven on a 90-day rental pilot supplying cars to San Francisco drivers.
First-order effects
- Zipcar faces a factory-backed competitor in its core dense-urban segment, where GM can subsidize fleet costs out of manufacturing scale; Uber sees an automaker positioning itself between drivers and vehicles they'd otherwise rent or own.
Second-order effects
- The competitive pressure converts into complementarity — Maven ends up renting cars to Uber drivers through the San Francisco pilot, showing incumbents can absorb a challenger by becoming its supplier.
Third-order effects
- If the pattern holds, automakers stop selling only to owners and build layered mobility platforms: Maven's later move into letting owners rent out their own GM cars via Peer Cars extends the same Manhattan test logic from company fleets to customer assets.
The trend: Legacy automakers are building shared-mobility platforms alongside vehicle sales, turning competitors like Uber into customers and owners into fleet suppliers.
