The New Flyer Xcelsior is a line of transit buses available in 35-foot rigid, 40-foot rigid, and 60-foot articulated nominal lengths manufactured by New Flyer Industries since 2008. In addition to the different available lengths, the buses are sold with a variety of propulsion systems: conventional diesel, compressed natural gas (CNG), diesel-electric hybrid, hydrogen fuel cell, overhead electric wire (Trolleybus) and battery electric. A future autonomous bus variant was announced in January 2021.

The New Flyer Low Floor is a line of low-floor transit buses that was manufactured by New Flyer Industries between 1991 and 2014. It was available in 30-foot rigid, 35-foot rigid, 40-foot rigid, and 60-foot articulated lengths. In addition to the different available lengths, the buses were sold with a variety of prime movers, ranging from conventional diesel and CNG combustion engines to diesel-electric hybrid, gasoline hybrid, and hydrogen fuel cell.

The Gillig Low Floor (originally named Gillig H2000LF and also nicknamed Gillig Advantage) is a transit bus manufactured by Gillig since 1997. Introduced as a second product range by the company (alongside the Gillig Phantom), the Low Floor later replaced the Phantom entirely. Since 2008, the model line has become the sole vehicle platform produced by Gillig. They are used for MBTA rail shuttles.

Since 2004, the Gillig Low Floor has been available in a diesel-electric hybrid configuration with the Cummins ISB engine; hybrid models are identified by their roof-mounted battery pack. Hybrid models have been produced with Allison BAE, and Voith series- and parallel-hybrid powertrains. In 2008, the Allison hybrid drivetrain was 81% more expensive than a conventional bus, which was partially subsidized by federal grants and expected savings in fuel and maintenance costs.

The Rapid Transit Series (RTS) city bus is a long-running series of transit buses that was originally manufactured by GMC Truck and Coach Division during 1977, in Pontiac, Michigan. First produced in 1977, the RTS was GMC's offering of an Advanced Design Bus design (the other entry was the Grumman 870 by competitor Flxible) and is the descendant of GMC's prototype for the U.S. Department of Transportation's Transbus project.

The Ford E-Series (also known as the Ford Econoline, Ford Econovan or Ford Club Wagon) is a range of full-size vans manufactured and marketed by the Ford Motor Company. Introduced for 1961 as the replacement of the Ford F-Series panel van, four generations of the model line have been produced. Marketed for both cargo and passenger transport, the E-Series has had multiple designs for both retail and commercial sale, including vans, and commercial-grade cutaway van chassis and stripped chassis (a chassis without bodywork).
