Carsharing is a big deal in many urban centers, and it's only going to get bigger. Last fall, one study predicted that the 2.3 million users around today will grow to more than 12 million by 2020. While that's good news for cities already dealing with congestion, some are sounding the alarm that all of this shared consumption is going to hurt car sales.

"The auto industry ignores or minimizes this trend at its peril" - Mark Wakefield

A new study by AlixPartners says that each carsharing vehicle will "avoid" 32 personal vehicle purchases in "bellwether markets" and that a total of 1.2 million vehicles will not be sold in the US through 2020. Roughly 16 million new cars will be sold in the US this year, so 1.2 million over six years - not counting the used car market - is small potatoes. AlixPartners got its data by asking 1,000 licensed drivers in ten cities with an established carsharing fleet and then 1,000 drivers nationally as a control sample about their purchasing intentions. The ten cities were Austin, Boston, Chicago, Miami, New York, Portland, San Diego, San Francisco-Oakland, Seattle and Washington, DC, where respondents said they found carsharing to be easier and more economical than owning a car.

The company's press release is full of dramatic language, saying the numbers are "sobering." AlixPartners' managing director Mark Wakefield is quoted as saying, "the auto industry ignores or minimizes this trend at its peril. ... The impact on the traditional automotive market could be explosive." Leaving aside the fact that AlixPartners' numbers are much higher than other predictions, if it is true that 32 new car purchases could all be satisfied by sharing one car, then that's a good thing. The streets will be less crowded and fewer resources will be used to make cars that are apparently not needed. Plus, automakers are not ignoring the trend, with Daimler starting up the Car2go service, BMW offering DriveNow and Ford partnering with Zipcar.

The official line at Zipcar is that each shared car takes 15 personally-owned vehicles off the road.

It's tough to know for sure how sharing a car affects ownership. Some older data from Carsharing Library shows that carsharing programs run at an average of 23 people per vehicle. And then this: "One study showed that when people joined the program 54 renounced a car purchase that they were planning. About one third never owned a car." The official line at Zipcar, the biggest carsharing service in the US, is that, "Each and every Zipcar takes 15 personally-owned vehicles off the road."

UPDATE: The AlixPartners report actually looks at used and new car sales, so this post has been updated to reflect that.

Lindsay Wester, public relations specialist at Zipcar, told AutoblogGreen that, "Since Zipcar's inception in 2000, our members have reported selling a primary or secondary car, or avoiding buying one altogether. Generally speaking, it's because they simply don't need a car full time. We're proud of the fact that we have played a role in reducing congestion and demand for parking in cities around the world.

Car2go's popularity is climbing as well, to the point where a new carsharing trip using a Smart Fortwo is started every 2.5 seconds. Paul DeLong, chief marketing officer at Car2go, told AutoblogGreen that Car2go is aware of the AlixPartner study, and says that there is, "no doubt [that] carsharing has played a role in purchasing decisions, especially for members that have 2-3 vehicles and wanting to downsize." He also said that carsharing can be good for auto companies. "Carsharing offers OEMs a great opportunity to expose those same members and their passengers to different models, new technology, and brands that they might never have considered driving or using before," he said.

AlixPartners Study Indicates Greater Negative Effect of Car Sharing on Vehicle Purchases

Estimated 32 personal-vehicle purchases avoided per each car-sharing vehicle in bellwether markets; projections suggest 1.2 million in avoided sales nationally through 2020


Though the auto industry in America is enjoying much better times of late, the global business advisory firm AlixPartners today released a sobering study suggesting that car-sharing services, in which drivers rent vehicles commercially or through peer-to-peer networks without going to a traditional car-rental location, are having-- and will increasingly have -- a greater impact than previously thought on the vehicle market.

According to the study, which surveyed 1,000 licensed drivers in 10 developed metropolitan car-sharing markets in the U.S. and 1,000 drivers nationally as a control sample, car sharing in the 10 key markets appears to be displacing vehicle purchases at a rate of 32 to 1 (one car-sharing fleet vehicle displacing 32 vehicles that would have otherwise been purchased). That's more than double the rate of many studies that have focused only on national averages. To date, according to the AlixPartners study, approximately 500,000 vehicle purchases nationally have been avoided due to car sharing. In addition, the study suggests that as car sharing grows in popularity, it could account for approximately 1.2 million more purchases avoided through 2020.

The 10 key car-sharing markets covered in the first part of the AlixPartners survey were Austin, Texas; Boston; Chicago; Miami; New York; Portland, Ore.; San Diego; San Francisco-Oakland; Seattle; and Washington, D.C.

"We focused on the markets where car-sharing services have achieved a degree of scale," said Mark Wakefield, managing director at AlixPartners and leader of the firm's Automotive Practice in North America. "Our study suggests that Americans' willingness to avoid vehicle purchases due to growing car-sharing options is higher than many have thought, further suggesting that the auto industry ignores or minimizes this trend at its peril.

"While the approximately 500,000 vehicle purchases avoided to date is itself a large number," continued Wakefield, "this study suggests that car sharing nationally could scale up as these 10 markets have, and if that happens, the impact on the traditional automotive market could be explosive."

Respondents in the 10 key markets picked ease of access, convenience and economics as key reasons for car sharing. Environmentalism, often regarded as a chief motivator for car sharing, was last among reasons selected (out of five possibilities). Meanwhile, 51 percent said they have avoided vehicle purchases due to car sharing and 45 percent indicated that they expect to avoid a future purchase. The survey also revealed that avoidance of personal-vehicle purchase is highest among younger consumers and, perhaps somewhat surprisingly, households with children – both possible harbingers for the auto industry.

The merger of Zipcar and Flexcar in 2007 is thought by many to have ratcheted up the commercialization of car sharing in North America. The recent advance by larger corporations -- including Avis (which bought Zipcar), Daimler, BMW and Enterprise -- into car sharing suggests that the industry is accelerating up an adoption S-curve, according to the study.

According to Wakefield, while smartphones and increasing urban density have driven adoption thus far, automated and driverless cars could be key enabling technologies for car sharing to grow well beyond the current early-adopters.

"Car sharing could really get traction as smartphone and automated-vehicle technologies pave the way for new mobility systems throughout America and much of the world," said Wakefield. "In the future, automated and, especially, driverless cars could be the killer apps for car sharing."

He continued: "The auto industry can be bypassed by these trends or can seize the opportunity to get out in front of them. It can do that by addressing the dissatisfaction with car ownership that many people, especially urbanites, have today, but also by leveraging the new technologies underpinning car sharing, being relevant in auxiliary services and adapting to what some are calling the new 'sharing economy,' where pay-by-use is often preferred over ownership for many types of products."

About the Study

The AlixPartners Car Sharing Outlook surveyed 1,000 adults (18 and older) with driver's licenses in 10 key metropolitan car-sharing markets in the U.S. (Austin, Texas; Boston; Chicago; Miami; New York; Portland, Ore.; San Diego; San Francisco-Oakland; Seattle; and Washington, D.C.) and 1,000 adults (18 and older) with driver's licenses nationally as a baseline. Respondents were representative of the U.S. population across key demographics and income ranges. The 10 key markets were chosen based on car-sharing fleet size, number of car-sharing competitors, population, affluence, urban density and university population.

      Type your comment hereWell Mercedes might have missed the chance to make a own Tesla but their car2go ist working really well. Especially the new electric smart cars with the tesla battery run like heck. the acceleration is brisk and as the car is so light it has a go cart like feel to it. mercedes knows that for cities they need a different solution. especially in europe. take amsterdam, it has narrow streets and very limited space. ppl do not want to sacrifice that to a car. also in stuttgart, germany I tried a lease. it is so convenient for short city trips. now it is so successful that the business area was expanded to the naighbour cities and ppl drive no larger distances with the cars. so mercedes targets the audience that would not buy a car at all. you get a small chip, take the internet or smartphone and there is always a car near you. you open it, enter your code and off you go. it was winter and the heater worked well. after the trip, park the car, end the lease and done. and if one takes a car with an "empty" battery and returns it to a charger one gets bonus miles. even as car owner for short trips, this is perfect.

      I'm afraid this article further confuses the issue by citing data that is hardly comparable. The good news is that there is quite detailed and reliable data on the impact of traditional carsharing services, such as Zipcar, on vehicle ownership, purchase, etc. The 32 vehicles reported by Alix Partners is on the low end of that reported by Dr. Susan Shaheen, Transportation Sustainability Research Center at UC Berkeley and other researchers. A good place to start is here: And finally, the article references to Car2Go one-way carsharing. There is virtually no public data about the consumer impacts of Car2Go membership, such as on vehicle ownership, purchase or parking. Only half the cities included in the Alix Partners have Car2Go service so that will affect the response.

      No. That is marketing puffery.

      This is great news if it's true! In future, I suspect cars will more and more become a service and not something that people fantasize about owning. As they sit doing nothing but corroding, denaturing, discharging, congealing, and otherwise depreciating 95+% of the time, owning one, especially in urban areas, is not very appealing. The day will come when one can order a self-driving vehicle whenever and wherever they are. Car sharing is a transitional step towards that day. What will folks do with all their new found garage space?!

      Great news! I like to see the car sharing industry expanding. Less cars = less pollution, etc. A lot of critics of car sharing say that insurance/liability in the main issue. That's only because your average insurance policy doesn't allow other drivers...Solution? Just get an insurance add-on that allows other people to drive your vehicle. 4autoinsurancequote has them for less than $10/month (just get quote), and you can share your car all you want. Other sites probably have it for even cheaper. It's the way of the future, and it's what I do. My vehicle is being rented out right now (relayrides). It's earning me money while I sit here at home.

      If each shared car eliminated 32 cars, then that would be a net gain to our economy as we would be allocating resources so much more efficiently. You would make more money selling a certain quantity of metal/plastic and people would save money by skipping out of car payments. win/win. But it's not true. Sorry.

      It's an interesting point and in its ultimate expression would truly decimate car production. And it might well just become the ultimate expression when cars can drive themselves. What greater luxury than Jeeves coming to pick you up whenever you want and only having to pay for the tiny bit when you actually use it. Never having to bother with parking, you just get out wherever you want and the car is gone. And your car is there no matter what city you are in. And the car is just the right size you need. 'Your' car drives you to a high speed transit center and your car will be waiting for you when you arrive. And if you want to take it to extremes then AI and 3D manufacture technology makes and maintains the vehicles so nothing costs anything at all. And this will happen. We just have to build some zombie interment camps first for tea party members, republican politicians, soldiers and oil and autoexecs.

      Yeah, so that is a good thing. Times are tough and not everyone can affort to purchase and maintain a car.

      No, it prevents city people from further crowding our already crowded mass transit system. It prevents countless minutes/hours each day from being wasted on public transportation. On the other hand, carsharing does result in a bit more emissions than taking public transportation, since buses are either electric, natural gas, or biodiesel, and trains are electric... and have a much lower footprint per passenger than a car carrying one person. But the wrong answer, is assuming that people will stay home without carsharing, or that people will go out and buy cars without carsharing.

      Well, if car shares run 23 people per vehicle, and 54% of those people sell a car when they join the program, then that is a pretty strong indicator that each carshare car removes about 12.4 private cars from the road. And as to whether it's a bad thing; No of course not. If they get their transportation needs met while spending less money, that is a net gain in the economy, and they will spend that saved money on other things, building other industries.

      Can't wait for the inevitable: unamerican, socialist, evil urbanites, latte liberals comments this story will engender as soon as it is cross posted to autoblog.
