But margins could come under pressure as the South Korean duo - which together rank fifth in global sales - plan to add capacity in China and Mexico, just as many analysts expect those markets and the United States to slow.
"With the global economy continuing its low growth, trade protectionism spreading and competition intensifying in the automobile industry, uncertainty is growing more than ever," Hyundai Motor Group Chairman Chung Mong-koo said in his New Year message to employees.
The 78-year-old chief said the automakers will launch more than 10 new models every year, including a new SUV for advanced markets and a Genesis G70 sedan this year.
The projected 5 percent rise in global sales for 2017 to 8.25 million vehicles easily beats the 1.9 percent rise forecast earlier by Hyundai Motor Group's own think-tank.
"The 2017 goal is slightly higher than my projection," said Ko Tae-bong, an auto analyst at Hi Investment & Securities.
Hyundai Motor likely clocked its fourth straight annual profit decline in 2016. Sales were hit by its sedan-heavy line-up, which meant it missed a boom in SUV demand, and sluggish emerging markets.
Hyundai Motor sold 4.86 million vehicles compared with its target of 5.01 million last year. Kia Motors sold 3.02 million vehicles, shy of its goal of 3.12 million.
