目次

The simultaneous emergence of four megatrends - electrification, automated driving, connectivity, and shared mobility are making it more difficult for manufacturers to forecast trends to guide them in investment and development.

This report examines current trends influencing the design of automotive transmissions for light duty vehicles and offers educated predictions of how these might play out by 2030.

Over the next several years, if not decades, the industry will likely continue to develop a wide variety of transmissions to support both traditional and electric powertrain technologies.

So what transmission development trends should companies focus on to be sure they remain competitive in the rapidly shifting global markets?

Five key strategic questions on the future of automotive transmissions:

  • 1. What is the probability that the emissions and fuel economy regulations projected for 2025 through 2030 will remain as currently envisioned? If they change, in what direction?
  • 2. Will the current trend of downspeeding to optimize the operating range of the ICE continue?
  • 3. How will electrification impact the development of the transmission?
  • 4. Will electrified powertrains demand significantly different development paths for hybrid and full EVs?
  • 5. What is the likelihood that a significant technical disruptor will be introduced in the next few years, significant enough and early enough to change the outcome predicted by the consensus view by 2030, all other factors remaining equal?

What this report offers:

This report explores possible answers to these and other key questions, and attempts to assign probabilities to the outcomes. The purpose of these probabilities is not to attempt to predict the future so much as imagine the possibilities available, and attempt to do so with as much insight as is possible today. The focus of the report is understanding the trends behind current developments and extracting insights to help the reader plan and make sense of the rapidly changing environment for automotive transmission manufacturers and suppliers.

Who buys Autelligence reports?

Currently over 250 companies have corporate or individual subscriptions to reports from Autelligence. Most reports are bought by CEOs, other C-level executives, partners, directors, vice-presidents and country managers at automotive suppliers across marketing, engineering, R&D, and purchasing functions. Subscribers also include OEMs, financial analysts and management consultants.

What the experts say:

Dr Joerg Gindele, Senior Director of Core Engineering, Magna Powertrain
“Multispeed transmissions will still be required, even with the move towards electric vehicles. Non-hybrid combustion engines now have up to ten gears, and in mild and full hybrids it still makes sense to have seven speeds”

Prof. Dr. Leopold Mikulic, Managing Director of Mikulic Consulting
“By 2030, it's likely that electrified CVTs and AMTs with integrated electric motors will gain market share in the more cost-sensitive volume segments”

Larry Nitz, Executive Director of Global Propulsion Systems, General Motors
“Combustion engines and multi-gear / CVT transmissions will retain significant market share, but by 2030 most will have significant connected and electrified content for regenerative braking, load shifting and EV driving”

Professor Dr.-Ing. Stefan Pischinger President & CEO, FEV Group
“ICE-only drives will still require multispeed transmissions in 2030. Multispeed transmissions will also gain market share in BEVs seeking to improve efficiencies across the operating range”

Carsten Weber, manager of Engine and Powertrain Systems, Ford
“The role of transmissions will change. Instead of being the element that adjusts torque and speed between engine and wheel, they will become intelligent performance distributors that manage energy consumption, emissions and driving behavior”

Oscar Sarmiento, Head of Engineering, Japan, Continental
“Electrification will further push CVT applications in vehicles with large comfort demands for megacities”
