The Fit went on sale in the United States and Canada in April of 2006 as a 2007 model year vehicle. It replaced the Civic hatchback for North America. Honda hopes to sell 33,000 Fits in 2006 and 50,000 per year afterwards to combat rival Toyota Motor Corporation's Scion marque. The Fit takes over for the Civic as Honda's chief entry-level subcompact; the Civic continues to grow in size and price and it was reclassified as a compact (larger than a subcompact) in 2001.

In keeping with Honda's safety initiative, the Fit is offered in North America with standard side airbags, side-curtain airbags, and ABS, in addition to the mandatory front airbags. Due to differing safety regulations, North American Fits have larger bumpers than the rest of the world, resulting in a slight increase in overall length. For the 2008 Model, US models come with a government mandated Tire Pressure Monitoring System (TPMS) to alert the driver of low pressure in any of the 4 stock wheels. Unlike some systems, the system in the 2008 Fit notifies the driver that a tire is low, but not which one.

The Fit is offered in two variants in the United States (Base and Sport), and three in Canada (DX, LX and Sport). Differences are primarily limited to cosmetics and standard equipment. All models share the same 1.5 L 109 hp (81 kW) engine and standard 5-speed manual transmission. A conventional 5-speed automatic transmission is optional, instead of the CVT found throughout the rest of the world. The Fit Sport receives paddle shifters mounted behind the steering wheel when ordered with the automatic. In the United States, the base model is priced at US$13,850, with the automatic transmission adding $800 and the Sport package adding $1,320. In Canada, it starts at CAD$14,980 for a DX with manual transmission, and goes to $20,880 for a Sport with automatic transmission.

For 2006, 27,934 Fits were sold in the United States. 45,953 units were sold between January 2007 and October 2007. A total of 73,887 Fits have been sold in the U.S. since its introduction in April 2006 through October 2007.^[4]

The 2008 Fit is largely unchanged from the 2007 with the exception of the TPMS and new windshield wipers that abandon the large rubber blade design to a more traditional rigid plastic with thin rubber blade design. MSRP has also increased roughly $100US
