This report addresses the technical challenges engineers must face, including the issues of storage devices, generation of the 42 volts, and distribution of power. It contains information on all of the critical aspects related to the adoption of this technology.

Development of higher-voltage electrical systems in vehicles has been slowly progressing over the past few decades. However, tightening vehicle efficiency and emissions regulations and increasing demand for onboard electrical power means that higher voltages, in the form of supplemental 48 V subsystems, may soon be nearing production as the most cost-effective way to meet regulations. The displacement of high-wattage loads to more efficient 48 V networks is expected to be the next step in the development of a new generation of mild hybrid vehicles. In addition to improved fuel economy and reduced emissions, 48 V systems could potentially save costs on new electrical features and help better address the emerging needs of future drivers. Challenges to 48 V system implementation remain, leading to discussions by experts from leading car makers and suppliers on the need for an international 48 V standard. Initial steps toward a proposed standard have already been taken.

Aviation propulsion development continues to rely upon fossil fuels for the vast majority of commercial and military applications. Until these fuels are depleted or abandoned, burning them will continue to jeopardize air quality and provoke increased regulation. With those challenges in mind, research and development of more efficient and electric propulsion systems will expand. Fuel-cell technology is but one example that addresses such emission and resource challenges, and others, including negligible acoustic emissions and the potential to leverage current infrastructure models. For now, these technologies are consigned to smaller aircraft applications, but are expected to mature toward use in larger aircraft. Additionally, measures such as electric/conventional hybrid configurations will ultimately increase efficiencies and knowledge of electric systems while minimizing industrial costs.

This compendium presents the most complete design and engineering story available anywhere about this groundbreaking new vehicle. It also introduces you to the engineering team and how they made the world’s first production extended-range electric vehicle a reality. Combining articles from SAE International’s Vehicle Electrification and Automotive Engineering International magazines, new SAE technical papers, and all-new content, this full-color book is the only one of its kind that lifts the veil on how the GM team and key supplier partners met the difficult engineering challenges faced in developing the Volt. Topics include the Volt’s systems, components, and model-based design; a behind-the-wheel look at a Volt prototype; and how the Volt’s engineering team used OnStar to collect test drive data from preproduction Volt vehicles.

The aerospace ecosystem is a complex system of systems comprising of many stakeholders in exchanging technical, design, development, certification, operational, and maintenance data across the different lifecycle stages of an aircraft from concept, engineering, manufacturing, operations, and maintenance to its disposal. Many standards have been developed to standardize and improve the effectiveness, efficiency, and security of the data transfer processes in the aerospace ecosystem. There are still challenges in data transfer due to the lack of standards in certain areas and lack of awareness and implementation of some standards. G-31 standards committee of SAE International has conducted a study on the available digital data standards in aircraft asset life cycle to understand the current and future landscapes of the needed digital data standards and identify gaps. This technical paper presents the study conducted by the G-31 technical committee.

Ride along as three children take a spin in a self-driving car and share their thoughts at the SAE Demo Days at Babcock Ranch.

In 1990 in the USA, Section 206 of the Clean Air Act ushered in a new era in passenger car and light truck service and maintenance. Ensuing requirements led to introduction of sophisticated vehicle on-board diagnostic systems. These systems demand the increasing sophistication of service providers. The amount of service information has expanded exponentially. The sophistication of the tools needed to diagnose and repair vehicles has become increasingly complex. To meet the needs of today's service professionals, new systems had to be developed. The convergence of regulations, vehicle complexity, tool capabilities and the growing volume of service information required the vehicle producers and service communities to implement more efficient information delivery systems.

Dramatic changes in transportation are coming. Cities and states looking to be at the forefront and reap the benefits, need an engaged and informed citizenry. Hear how the SAE Demo Day in Tampa supported Florida's AV initiatives and can benefit states nationwide.

In May 2018, SAE International in partnership with THEA and leading AV technology companies gave citizens in Tampa a chance to test ride the future. The event included a pre- and post-ride survey, a ride in an automated vehicle, interactive displays and engagement with industry experts. See highlights of the event and feedback from participants.

The public sees endless reports about self-driving cars. Some are breathless, others scary. Yet outside of small tech and policy circles, few people have actually experienced this coming technology. SAE gave people the opportunity May 2018 in Tampa. Hear what they had to say after the experience.

It is ironic that as aircraft have gotten more sophisticated, much of their manufacture has remained manual. However, as orders for commercial aircraft have dramatically increased over the past years and are expected to remain on that trajectory, the competition has become not just about how fast new technologies can be put on the aircraft, but about how fast the aircraft can be manufactured and delivered. Enter ever increasing automation and robotics. Just as it has taken multiple years to reach the sophisticated content levels on current generation aircraft, so too has it been necessary to continually learn new ways and means to increase automation on the manufacturing floor. For both aircraft on the flight line and on the production line, safety is paramount.
