dispensing with the need for a gearbox. This range of torque also gave them rapid
acceleration. Although electric motors were much lighter than internal combustion
engines, the weight advantages were offset by the need for heavy batteries, which were
also the most expensive part of an electric car, costing from $10,000 to $25,000.
Electric cars were either redesigns of existing gasoline-powered models (e.g., the
Ford Focus Electric and Volkswagen’s e-Golf) or newly designed electric cars (e.g., the
Tesla Roadster and Nissan’s Leaf). Complete redesign had major technical advantages:
the battery pack formed part of the floor of the passenger cabin, which saved on space
and improved stability and handling due to a lower center of gravity.
Predictions that electric cars would rapidly displace conventionally powered cars
proved false. In 2017, global registrations of plug-in EVs totaled 1,223,600. Although
this was a 58% increase on 2016, this still represented just 1.3% of total sales of cars and
light trucks, with China the world’s largest market. Forecasts of the growth in demand
varied substantially—most predicted that the market share of EVs would be between
7% and 20% by 2025. Much depended on government policy: by March 2018, eight
countries had announced their intention to ban the sale of new gasoline and diesel-
powered vehicles at some date between 2020 and 2040. The countries where EVs
had gained the highest market shares were those with the most generous government
incentives. Thus, in Norway, where plug-in EVs had a 39% market share in 2017, incen-
tives included exemption from purchase taxes on cars (including VAT), road tax, and
fees in public car parks, and the right to use bus lanes. In the US, federal government
incentives included development grants to the manufacturers of EVs and batteries, and
tax credits for purchases of EVs. Several countries had announced a phasing out or
scaling back of subsidies. The US federal government’s $7,500 tax credit to buyers of
Tesla cars would be halved In January 2019 and phased out a year later. The impact of
lower fiscal incentives would be offset, in part, by EVs falling prices relative to conven-
tional vehicles—in addition to lower battery prices, EVs benefitted from fewer compo-
nents than conventional vehicles.
“Range anxiety”—the threat of running out of battery charge—was seen as a major
obstacle to the market penetration of battery-powered EVs. However, by 2018, these
concerns were dissipating. Improved battery technology had doubled the average
range of EVs between 2015 and 2018. Secondly, the density of charging stations was
increasing rapidly. By the end of 2017, there were 210,000 publicly available charging
points in China, 43,000 in the US, 33,000 in Netherlands, and 24,000 in Germany.
Although battery-powered electric propulsion was the leading zero-emission tech-
nology available to automakers, it was not the only one: fuel cells offered an alternative.
Several automakers had developed prototypes of fuel-cell cars, but in 2018 only Toyota
was producing cars powered by fuel cells. The dependence of fuel cell vehicles on a
network of hydrogen fueling stations was the main disadvantage of this technology.

Tesla Motors, 2003–2018
Elon Musk is a South-African-born, serial entrepreneur, who moved to Canada at the
age of 17. He cofounded Zip2, a developer of Web-based publishing software, and then
PayPal, which earned him $165 million when it was acquired by eBay. His next start-
ups were SpaceX, which became the world’s leading satellite launch company, and
SolarCity, which aimed to become “the Walmart of solar panel installations.”
Tesla Motors Inc., founded in 2003, was named after Nikola Tesla, a pioneer of
electric motors and electrical power systems. In 2004, Musk became its lead shareholder
