The NABI SFW is a line of standard (high)-floortransit buses available in 40-foot rigid (NABI 416) and 60-foot articulated (NABI 436) nominal lengths, manufactured by the Ikarus USA joint venture, then by American Ikarus and North American Bus Industries (NABI) between 1989 and 2013. In addition to the different lengths, the buses were sold with a variety of prime movers, including conventional diesel and CNG combustion engines and hybrid diesel-electric power.
NABI introduced the low-floorLFW line in 1997 to supplement the older SFW line; both of the NABI bus product lines featured similar styling, with the LFW having comparatively taller side windows over the low-floor portion of the bus. NABI was acquired by New Flyer in 2013, and NABI production was wound down by 2015; the last SFW order (for a set of NABI 416 buses) had been delivered in 2013.
