New Flyer Low Floor
American low-floor transit buses
The New Flyer Low Floor series is a line of low-floor transit buses that was manufactured by New Flyer Industries for the North American market from 1991 to 2014. It was produced in a variety of variants, available in four nominal lengths (ranging from 30 to 60 feet) and three body styles, and with a variety of powertrains, including diesel and compressed natural gas engines, and hybrid electric systems.
Variants
The Low Floor series includes 38 individual variants, each named according to their powertrain, length, and body style. For example, the D40LF (the most common variant) is a diesel-powered, 40-foot rigid bus with the original styling; while a DE60LFR is a diesel-electric hybrid, 60-foot articulated bus with the "Restyled" body.
Not all possible combinations of models, lengths, and powertrains were actually built; those which saw production are noted below:
History
The original design of the New Flyer Low Floor was based on the B85/B86, a European-market bus produced from 1984 to 1988 by Den Oudsten, a Dutch bus manufacturer which owned New Flyer from 1986 to 2002. A B85 was sent to the United States for testing in 1988, and served as the basis for the development of the Low Floor series.
Production of the Low Floor Series began in 1991 at New Flyer's assembly plant in Grand Forks, North Dakota. The first unit, of the D40LF variant, was delivered to the Port Authority of New York and New Jersey in 1992. The first articulated Low Floor (a D60LF), an ex-demonstration unit, was sold to Strathcona County Transit in Alberta in 1996.
New Flyer introduced the Invero series of buses in 1999 with the intent that it would replace the Low Floor line; few were sold, and the Invero was discontinued in 2007.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
