Top Five Electric Buses in the United States of America
With an aim to take the USA towards zero-emission transportation, the Joe Biden government has proposed a USD174 billion program for bolstering electric vehicle adoption. Innovation in the emerging heavy-duty electric bus sector by the major players operating in the market is boosting the efficiency and reducing maintenance costs of e-buses, which is boosting its market growth.
Increased focus on green and sustainable future has put a great emphasis on electrification. In the USA, vehicular pollution accounts for approx. 29% of the country’s net greenhouse gas emissions, therefore President Joe Biden’s plan has a broad intent in electrifying the automobile sector for reducing carbon footprint and reach environmental goals. Although passenger cars dominated the electric vehicles market, now electric bus adoption has been booming in the USA for reducing costs and carbon emissions from the public transport sector. According to Bloomberg’s Electric Vehicle Outlook 2020, e-buses are expected to hold a majority of the global bus fleet by 2040.
Here are the top five electric buses dominating the USA market.

NFI Group Inc. Xcelsior CHARGE™
Available in 35-foot, 40 foot, and 60-foot models with a passenger capacity of up to 88, Xcelsior Charge NG is a long-range electric bus, harnessing the best technology on the market. Its streamlined design enhances energy recovery, reduces weight, and increases energy density. The electric bus is sustainable, easier to maintain, and delivers high performance due to fewer parts in the vehicles. The new generation of batteries in the electric bus utilizes an active liquid cooling system to optimize temperature, enhance power efficiency, and increase battery life. Besides, the batteries are lightweight, easier to maintain, dustproof, and waterproof. The new fleet of electric buses by NFI consists of fewer parts as the manufacturer has reduced the parts from 250 to 50 (90% reduction).
The Siemens ELFA 3 traction system embedded in the Xcelsior CHARGE™ electric bus offers up to 90% energy recovery and even weighs 69% less than ELFA 2. The efficient design, compact inverters, and drive controllers allow greater capacity for passengers and ensure a safe experience. The Xcelsior CHARGE H2 utilizes eco-friendly hydrogen and fuel-cell technology to generate electricity for extended-range zero-emission transit operations. The vehicle can save around 85-175 tons of carbon emissions annually compared to traditional diesel buses as the only tailpipe output is clean water vapor. Besides, the electric bus features regenerative braking while decelerating, which aids in reducing energy consumption.
