  • Carmakers Should Be Able to Meet Future Emissions Targets Mainly Through Improvements to Gas Engines, Says a New Report by The Boston Consulting Group

  • Conventional Technologies Offer the Potential to Cut CO2 Emissions by About 40 Percent, but Manufacturers Will Need to Pull Multiple Levers Simultaneously, New Research Shows

DETROIT, July 6, 2011—Internal combustion engines are improving their ability to cut CO2 emissions at a lower cost than expected, and, as a result, carmakers should be able to meet 2020 emissions targets mainly through improvements to conventional technologies, according to a new report by The Boston Consulting Group. The report, Powering Autos to 2020: The Era of the Electric Car?, is being released today.

Internal-combustion-engine (ICE) technologies offer the potential to cut tailpipe emissions of carbon dioxide by approximately 40 percent at a cost to consumers of $50 to $60 per percentage point of reduction for an average passenger car—roughly half the cost of what was expected three years ago, the report says. But original equipment manufacturers (OEMs) will need to pull multiple levers simultaneously to achieve such dramatic reductions. Modifications to combustion technologies, transmissions, vehicle mass, aerodynamics, and power management will all be necessary.

Although conventional technologies will pose stiff competition for electric vehicles (EVs), BCG’s research also found that there is a distinct “green” consumer segment that will be willing to pay a significant premium for EVs even if the total cost is higher.

“Electric cars will undoubtedly play an increasingly large role in many countries’ plans in the decades ahead as energy independence and environmental concerns intensify,” said Xavier Mosquet, a senior partner in the firm’s Detroit office, global coleader of BCG’s Automotive practice, and lead author of the report. “But they will gain only modest ground to 2020. Gasoline- and diesel-powered vehicles are improving faster than expected and will continue to dominate the global landscape.”

The report examines the challenges and opportunities facing EVs—including pure battery, range-extended, and plug-in hybrids—and identifies wildcard scenarios that could have a major impact on demand. It also looks at prospects for traditional ICEs and hybrid electric vehicles (HEVs), with a focus on the advanced ICE-technology choices carmakers will face as they wrestle with tightening emissions standards.

The report is based on proprietary economic analysis, BCG’s consumer research, and interviews with industry experts. Other key findings include the following: 

  •  China and Europe—not the U.S., as many believe—will be the largest markets for EVs in 2020. 

  •  Based solely on total-cost-of-ownership (TCO) economics, EVs will not be the preferred option for most consumers. Battery pack costs are forecast to fall sharply (approximately 64 percent from 2009 levels) to $360 to $400 per usable kilowatt-hour (kWh) by 2020. However, to the consumer, this still represents a cost of $9,600 per vehicle for the typical 20-kWh battery necessary for a pure battery EV.

  •  High costs notwithstanding, EVs will see relatively strong uptake from a distinct segment of environment-conscious consumers around the world who are willing to pay an average up-front premium of $4,500 to $6,000 to purchase a green vehicle, do not expect their up-front investment to be recouped over time through lower operating costs, and are willing to pay about 10 to 20 percent more in terms of the TCO over the vehicle’s life. These consumers represent 13 percent of consumers in China, 9 percent of those in Europe, and 6 percent of those in the U.S.

  •  China is a major wildcard. Assuming that the government remains committed to EVs, BCG projects that these vehicles will represent 7 percent of the country’s new-car sales in 2020. Despite this moderate penetration, China will become the world’s largest market for EVs due to its overall market size. 

  •  Europe will become the second-largest market for EVs in 2020 with a projected 8 percent share of new-car sales, supported by consumers’ willingness to pay for green technologies, the region’s stringent emissions standards, and high gasoline and diesel taxes. 

  •  Sales of EVs in Japan and the U.S., meanwhile, will rise steadily through the decade but remain below those in China and Europe. BCG expects EVs to account for 5 percent of new-car sales in Japan and 2 percent of new-car sales in North America in 2020. 

  •  Taken together, EVs and HEVs could claim 15 percent of aggregate new-car sales in the four major markets (North America, Europe, China, and Japan) in 2020. As OEMs ramp up capacity to meet this demand, they will have to simultaneously invest in advanced ICE technologies—adding complexity to their operations.

  •  As OEMs wrestle with advanced ICEs and EVs, they will have to keep an eye on a compelling alternative fuel source—compressed natural gas. CNG could expand beyond its current strongholds with transit buses and airport shuttles and see growing adoption by delivery vehicles, government fleets, and taxis.

“There is little doubt that regulations and oil prices, as well as technology and consumer preferences, create a high degree of uncertainty,” said Mosquet. “All market participants have to prepare for and retain the flexibility to switch among at least three different paths the industry could take: the pragmatist path, with a focus on ICE improvements, HEVs, and a limited share of EVs; the breakthrough path, marked by a game-changing improvement in battery technology; and the green path, where oil prices greater than $250 per barrel drive strong government support for EVs and HEVs and, potentially, CNG.”

Marco Gerrits, a partner in BCG’s Beijing office who heads the firm’s Automotive practice in Greater China and is a coauthor of the report, noted that demand for electric cars in China is especially hard to predict. The Chinese government has ambitious plans to drive adoption of EVs. Its latest draft plan calls for 500,000 EVs—passenger cars, trucks, and buses—on the road by 2015 and 5 million by 2020. In 2010, however, only around 2,000 electric cars were sold despite central-government incentives worth up to $9,000.

“To secure a higher adoption of EVs, China’s government may resort to measures beyond the current incentives—for example, driving restrictions,” said Gerrits. “This makes the Chinese market a major wildcard. EV OEMs and suppliers should prepare for multiple volume and penetration scenarios.”
