Battery-electric trucks (BEV) will have a plurality of sales in the medium- and heavy-duty segments. However, six fuel and powertrain types — diesel, gasoline, compressed/liquid natural gas (CNG/LNG), hybrid-electric (HEV), fuel-cell electric (FCEV), and hydrogen/internal combustion engines (H2-ICE) — will maintain significant percentages of sales.

Growth Driven by Regulations

In the midterm, electrification growth will be primarily driven by the regulatory environment, with subsequent sales driven by lower costs for zero-emissions vehicles (BEV, FCEV, and H2-ICE) compared to gas- and diesel-fueled vehicles, according to S&P Mobility.
