Powertrain to 2025: Trends and Risks

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

Modern powertrains are changing fast.

Modern powertrains are an integrated and jointly developed combination of internal combustion (IC) engines, batteries, transmissions (sometimes), generator/motors and complex control systems.

A lot of attention has been focused on smart cars, connectivity and full electrification as disruptors of the auto sector.

But a huge disruption is already happening in current powertrain developments.

“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 trends might develop by 2025 or 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 Autelligence surveys of experts.

The report is more than a one-off download – the package includes quarterly updates of development in powertrains electrification, written by the report author – for a year after the initial report purchase.

That ensures that between each major refresh edition of the report we supply you with on-going insight into developments and the changing balance of forces acting on powertrain development. Updates are issued in April, July, October and January

Topics covered in past updates include the current state of review of the US 2022 – 2025 CAFE standards, the impact on EV sales of US politics, as well as full results of the 2017 Autelligence Future of the Powertrain Industry Survey.

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
