Technical trends and developments in the five major powertrain areas. Analysis, discussion of recent events and developments and assessment of their likely impact.

Attention has recently been focused on self-driving vehicles and full electrification as major disruptors for the auto sector in the next decade.

But for the next several years the industry is likely to be dominated by radical changes occurring WITHIN the internal combustion (IC)-engined automotive model, as new engine management and optimization technologies and partial electrification address changes demanded by regulators and markets, such as achieving carbon emission reductions and fuel economy gains despite the sidelining of diesels.

“Powertrain to 2025: Trends  and Risks” examines the impact of these developments on the five major elements of the future powertrain:

  • IC engines
  • Transmissions
  • Control Systems
  • Batteries
  • Electric Motors

The report looks at technical trends and developments in each of these areas, and projects how those they might develop through to 2025 and 2030.

The report takes a unique approach to assessing the central track of the industry’s technological roadmap – and then discusses the threats and challenges to that projection as way of analyzing the risks and opportunities that will dominate the next decade.

In other words it establishes the consensus view, and then challenges it by identifying key uncertainties and potential disruptors.

Each chapter summarizes current developments for each of the technology areas, and then pulls them together into plausible, alternate scenarios to the central outlook to help planners “bookend” the best and worst cases.

The report builds on a series of in-depth studies of different powertrain technologies, as well as surveys of experts.

Who is the report for?

Chief Executive Officers, Marketing Directors, Business and Sales Development executives, Product and Project management, Purchasing and Technical Directors that need a powerful third party perspective and overview of the trends and issues in their sector and the potential ramifications for their business.

Author of this report: Bruce Morey

With over twenty five years of experience in technology development, research, and management, Bruce Morey brings a unique perspective to looking at the future of automotive engineering.  Sixteen years in the defense industry exposed him to a number of forward-looking methodologies, including scenario and contingency planning.  Six years in automotive product development at Ford Motor Company gave him an inside look at the day-to-day challenges and pressures of delivering quality vehicles and engines that customers want to buy, at an affordable price to both customer and company.

Mr Morey has published articles have covered computer simulation in support of engine development, future fuels, fuel cell vehicles, manufacturing, automotive engineering and product development.  He is also the author of two books, Automotive 2030 North America and Future Automotive Fuels and Energy, both published by SAE International.

Mr. Morey earned both Bachelors and Masters degrees in mechanical engineering from the University of Michigan. Mr. Morey is a member of SAE International and the Society of Manufacturing Engineers.

What the industry is saying

“Gone are the days when a gasoline engine and a transmission designed independently would meet a customer’s expectations. Today’s customer is demanding unprecedented technology integration that requires unprecedented engineering and supplier partnerships.” Dan Nicholson, Vice President, GM Global Propulsion Systems

“With many automotive markets worldwide, e-mobility is still a niche market. However, this will quickly change when lawmakers introduce stricter international emissions limits in the coming years.” Jörg Grotendorst, Head of the ZF E-Mobility Division

“Electrification has to come to Europe to meet tougher emission standards and the diesel is going to pay the highest toll. This will cause huge challenges for automakers and suppliers because they will need to change their powertrain manufacturing infrastructure.”  Stefano Aversa, deputy chairman, AlixPartners
