Pricing will be announced closer to the car's launch date, Mercedes-Benz said.
"The new Mercedes-AMG C43 Coupe makes sports car technology and motor racing flair more attainable and appealing to a broader customer base," said the automaker in a statement.
The C43 Coupe is equipped with a 3.0-liter V6 biturbo engine that churns out 362 horsepower. It features a new nine-speed automatic transmission and sprints from zero to 60 mph in 4.6 seconds.
Mercedes-Benz did not provide fuel economy estimates.
Optional features include an AMG head-up display, AMG exterior carbon-fiber package and AMG performance exhaust system.
The cabin gets a multifunction sport steering wheel in black leather and red contrast topstitching.
"The extension of the C-Class family to include the new C43 Coupe is another component in our growth strategy," said Mercedes-AMG Chairman Tobias Moers in a statement. "It not only enriches the wide lineup of the C-Class family, but also starts the introduction of a whole series of new '43' models this year."
Edmunds says: Car shoppers seeking a sporty flair will want to check out the 2017 C434 Coupe.
