Chief Executive Officer
The transition to electrified vehicles in OEM portfolios
is progressing, but internal combustion engines
(ICE) will continue to power millions of new
vehicles for a still undetermined period, according
to top powertrain executives. " Let's just say that
by the end of the decade, it's a 50/50 mix of ICE
and BEV [battery electric vehicles]. But that 50
percent ICE is going to be heavily influenced by
the hybrids, " David Filipe, VP of vehicle hardware
modules at Ford Motor Co., said during the April 7
" The Future Powertrain-Propulsion Portfolio
Challenge " panel session at April's SAE WCX
2022 conference in Detroit.
Filipe offered this statistic: Of the orders
taken to date for the 2022 Ford Maverick, 67%
are for the compact pickup's standard hybrid
powertrain, a 2.5-L Atkinson-cycle 4-cylinder
SAE-rated at 191 hp (142 kW) when combined
with the electric motor. Maverick's optional
engine is a 2.0-L EcoBoost 250-hp (186-kW)
gasoline engine. Ford will launch more hybrids
in the future, Filipe confirmed.
One-quarter of vehicle sales last year for
Toyota were electrified vehicles, the vast majority
hybrids. The automaker's future includes
BEVs, hybrid- and plug-in hybrid vehicles and
fuel cell EVs. " We don't believe a one-size-fitsall
approach will work, " Dante Boutell, VP of
powertrain design for Toyota North America,
told the SAE audience. " There are customers
out there that have specific needs that require
multiple technologies and systems. "
General Motors' road to zero emissions
6 May 2022
includes 30 new EVs by 2025. The automaker
is investing $35 billion through 2025 for its EV
and autonomous-vehicle portfolios. " We intend
to be the electric-vehicle market leader
in the U.S. market by the end of decade, " asserted
Dan Nicholson, GM's VP of global electrification,
controls, software and electronics.
Even though electrified vehicles are making
significant inroads, Ford's Filipe predicts that
ICEs will be in-play for another 10, 15, possibly
20 years. Said GM's Nicholson, " I don't know
of any OEM that has made its last [IC] engine
or is done with [ICE]. "
Supporting ICEs
The protracted shift from ICE-powered to electrified
vehicles is keeping the supply chain very
busy. " There's going to remain a market for
ICE, and the supply base is going to be challenged
with the diversity of technologies required, "
said Andrew Clemence, senior VP of
green technology and the electrification business
unit leader at Denso North America.
The progression to electrified vehicles requires
a balance with ICE. Ford's Filipe noted
that in the past decade, conventional powertrains
were typically upgraded every three to
five years - " a very quick rate of updates in
technology, " Filipe said. " We're going to slow
that down. But we still need to make the updates "
to meet ongoing emission requirements.
According to Toyota's Boutell, whether ICE
technology updates are compliance-related,

SAE International Sections
SAE International Sections are local
units comprised of 100 or more SAE
International Members in a defined
technical or geographic area. The purpose
of local Sections is to meet the technical,
developmental, and personal needs of the
SAE Members in a given area. For more
information, please visit sae.org/sections
or contact SAE Member Relations Specialist
Abby Hartman at abby.hartman@sae.org.
SAE International
Collegiate Chapters
Collegiate Chapters are a way for SAE
International Student Members to get
together on their campus and develop
skills in a student-run and -elected
environment. Student Members are vital
to the continued success and future of
SAE. While your course work teaches
you the engineering knowledge you
need, participation in your SAE Collegiate
Chapter can develop or enhance other
important skills, including leadership,
time management, project management,
communications, organization, planning,
delegation, budgeting, and finance. For
more information, please visit students.
