One of the questions I‘m most frequently asked is, “When will electric vehicles become mainstream?” to which I invariably reply, “They already are.”

The electrification of the automobile is arguably the greatest force transforming our industry. Appearing as early as the 1800‘s, electricity has served us increasingly well across the automotive spectrum, giving rise to continuous advances in lighting, ignition, communications, processing, propelling, regenerating, all manner of efficiencies, and more. Today, electricity—along with the connectivity and autonomy that it enables—is powering the industry‘s transformation towards a new paradigm of sustainable mobility for all.

So, electrification is with us, it‘s pervasive, and it‘s transformative. And it‘s also a core strength of what we do at Toyota. Three exciting examples help illustrate this. The first is Toyota‘s dynamic and holistic “mobility for all” electric lineup set to transform the 2020 Tokyo Olympics into the greenest global games in history. The second is Toyota‘s development of market–shaping, transformational–transport–enabling electrification initiatives with worldwide collaborators like Uber, Shell, Panasonic, BMW, SoftBank, Subaru, BYD and Mazda. The third is Toyota’s commitment and, crucially, capability to offer an electrified version of every vehicle model we make by 2025.

And we‘re not stopping there. In fact, as revealed earlier this year, Toyota is teaming up with Japan‘s national aerospace and space agency to develop what many might call the ultimate, out–of–this–world, electric SUV—a pressurized manned lunar expedition rover—to take our advanced, versatile and durable Toyota fuel cell electric technology to the moon.

Our electrification roots themselves are grounded in another history–making launch—that of our very first hybrid–electric, the Toyota Prius, 20 years ago. With revolutionary vehicles like the Prius, and equally transformative descendants like our zero–emissions fuel cell electric Mirai, Toyota has long helped pioneer the path to electrification, providing a range of products intelligently engineered to meet our customers‘ diverse needs via varying levels of electric generation, regeneration and propulsion.

This layering, or stratification, of electrification is perhaps best illustrated by its efficiency and emissions benefits. If we begin with a vehicle powered by a conventional gasoline-fueled internal combustion engine, adding an initial layer of electrification via a regenerative braking, battery and motor system enables virtuous reductions in fuel consumption, engine size and harmful emissions. An example of this hybrid–electric approach is the class–leading 2019 Toyota Prius L Eco, with its impressive available 58 mpg city EPA rating, incredibly efficient 1.8L engine, and Super–Ultra–Low–Emissions output.

Adding a second level of electrification—in the form of expanded battery, electric motor, power control and operating capabilities—enables even greater efficiency and emissions gains. An example of a vehicle incorporating such advantages is the 2020 Toyota Prius Prime hybrid–electric plug–in, which allows customers to fuel either conventionally or electrically, with the ability to operate on battery power alone for up to 25 miles of zero–emissions driving. In a showcase of its versatility, the Prius Prime offers owners an EPA–estimated 133 MPGe efficiency and 640 miles of total driving range.

Highest on our efficiency scale is the third stratum of electrification—pure electric vehicles. These completely replace carbon–emitting internal combustion engines with electric motors to provide silent, smooth, clean propulsion. Traditional pure electric vehicles are powered by batteries upsized to provide sufficient performance, range and longevity. An example of such a battery–electric vehicle is the Accessible People Mover, or APM, that Toyota will introduce to help transform transport at the 2020 Tokyo Olympic and Paralympic Games.

An even more promising form of pure electric mobility is the fuel cell electric vehicle, such as the trailblazing Toyota Mirai. Vehicles like the Mirai utilize hydrogen to generate their own electricity onboard, while emitting nothing but water vapor from the tailpipe. Fuel cell electrics overcome many issues associated with battery electrics — lengthy recharging times, reduced range, diminished performance and lower infrastructure throughput. Fuel cell electric vehicles do require hydrogen fueling stations1, but nearly 40 such retail stations already exist in California to serve a growing population of thousands of vehicles. More hydrogen fueling stations are under development with the prioritized support of the state, and station development in the Northeast is also underway. For fundamental reasons such as these, our fuel cell electric vehicle program — based on our core, layered, hybrid–technology strength — is a central pillar in Toyota‘s pursuit of sustainable mobility (see Figure 1).

F1 / Toyota’s Global Electrification Strategy

Perhaps the most exciting aspect of fuel–cell–driven electrification, however, is its scalability. The need to reduce emissions across the transportation, commercial and community sectors is dramatic, increasing and global. And where these sectors converge, such as in the teeming goods–movement in port communities and their surrounding regions all over the world, this emissions issue has become critical.

A key means of addressing this problem is to electrify commercial freight transport, converting aging and polluting heavy–duty diesel fleets to pure, zero–emissions, electric propulsion. And Toyota is helping directly architect this transformation through our pioneering Project Portal Class 8 fuel cell electric truck initiative.

Established as a feasibility study to explore the potential application of our light–duty Toyota Mirai fuel cell electric technology to the high–emission heavy–duty truck sector, Project Portal has progressed rapidly from concept phase, to a pair of advanced demonstration prototypes, and now to the development of a large–scale, $82 million pilot program featuring 10 in–service trial trucks in conjunction with the State of California, the Los Angeles ports, Kenworth, Shell, UPS and many more. Through this transformative “Shore to Store” pilot, Toyota‘s Project Portal is helping prove that heavy–duty fuel cell electrics—with their range, weight, performance, refueling time, cargo capacity and infrastructure scalability advantages beyond battery electrics—have the potential to be the optimal solution for electrifying — and revolutionizing — global transport.

This transformational potential is visually summarized in Figure 2 below. Overall, fuel cell electric vehicles offer a compelling combination of market and societal benefits, particularly at scale, and, therefore, are an emerging core of Toyota‘s layered, customer-needs-based portfolio approach to electrification.

So, in summary, when someone asks you, “When will electric cars become mainstream? And how is Toyota participating?” you‘ll be able to smile and reply, “They already are, and we’re helping lead the way.”
