Pricing will be announced in mid-October.
But the redesign pits it against top European contenders as well.
"This 10th-generation Civic is quite simply the most ambitious remake of Civic we've ever done," said John Mendel, American Honda Motor Co. executive vice president, in a statement.
This is also the first time that Honda will offer a turbocharged engine in the U.S.
Only the sedan version of the 2016 Civic was revealed late Wednesday.
The 2016 Civic sedan will feature two all-new engines.
The Civic LX and EX models are powered by a 2.0-liter four-cylinder engine linked to either a six-speed manual transmission on the LX or a continuously variable automatic transmission (CVT). Civic EX-T, EX-L and Touring sedan models are equipped with a new 1.5-liter turbocharged four-cylinder engine and a CVT.
Honda said the 1.5-liter engine is the most powerful engine ever offered on a non-Si Civic in the U.S.
Engine specifications and EPA fuel economy numbers will be released closer to launch.
The 2016 Civic sedan is nearly 2 inches wider and 1 inch lower with a 1.2-inch longer wheelbase.
Exterior changes include a more compact and sporty front overhang, a longer hood and fastback-style tail. LED headlights are optional, while LED daytime running lights and LED taillights are standard.
The Civic's body is 25 percent more rigid and aerodynamics have been improved by 12 percent, the automaker said.
In the cabin, new standard equipment includes automatic climate control and a larger, reconfigurable new center console.
Soft-touch materials add to the premium feel.
The 2016 Civic sedan will be available with the Honda Sensing safety and driver-assist technologies, including collision-mitigation braking, road-departure mitigation and adaptive cruise control with low-speed follow.
Edmunds says: The long list of improvements to the 2016 Civic should boost it to the top of many shopping lists.
