Key additions in the Premium model included high-intensity discharge (HID) headlights, leather upholstery, heated front seats, a power moonroof, and an in-dash 6 disc CD changer.

The Navi model was only available as an upgrade to the Premium trim, adding a bilingual voice-activated navigation system, illuminated steering wheel controls, and a digital audio card reader.

Lastly, the 2.0 L DOHC i-VTEC engine, HID headlamps, chrome door handles, paddle shifters, and the 6 disc CD changer remained exclusive to the CSX as they were not available for Civics in Canada nor the United States.

The Type-S variant debuted as a 2007 model and uses the identical powertrain found in the US and Canadian market 2006-2011 Honda Civic Si, consisting of a 2.0L I4, 197 horsepower (147 kW) i-VTEC engine, 6-speed manual transmission and a helical limited-slip differential.

The "sport-tuned" suspension is identical to the US-only 2006+ Honda Civic Si sedan with stiffer springs, firmer damping and thicker stabilizer bars compared to the regular CSX and is supported on 215/45R17 all-season tires and 17-inch alloy wheels.

The 2007 CSX Type-S went on sale on November 6, 2006 with an MSRP of $33,400 Canadian at the same time as the Acura TL Type-S. For the 2008 model year the Honda Civic Si was offered as a sedan as well as a coupe, however the Acura CSX Type-S remained available since it has features not found in its Honda counterpart such as the navigation system and leather upholstery.

The decision to phase out the base CSX with cloth seats was due to the Honda Civic EX-L trim being available for the 2008 model year onwards.

Like the Honda Civic, the CSX received a mid-model change in 2009, most notably giving it Acura's trademark Power Plenum grille.
