Opportunities are offered by improved battery technologies, more powerful materials or mechanical technologies that work with gas pressure or water. Innovations in this area will account for between 0.1 and 0.6 trillion US dollars in 2025. McKinsey expects at least 40% of new vehicles to have an electric motor by then.
