Net profit for the January-March period fell 2.2 per cent to 1.98 trillion won (USD 1.83 billion), compared with 2.03 trillion won a year ago, the company said in a statement.
Chief financial officer Lee Won-Hee attributed the result - which still beat the 1.71 trillion won predicted by 23 analysts surveyed by Bloomberg News - to a "dramatic" weakening of the Russian and Brazilian currencies against the Korean won.
Hyundai books some 85 per cent of its sales overseas, so the strength of the won against other currencies can slash the value of the firm's profits at home.
Sales of its Russian and Brazilian plants calculated in the Korean currency dropped 41.2 per cent and 11.2 per cent from a year ago.
Lee said company had been trying to "offset the impact of currency swings in the emerging markets by raising prices... and trying to secure as much auto components locally as possible".
But the market cheered the results, with Hyundai's shares rising 3.24 per cent to 175,500 won.
"Hyundai has had a tough quarter," IBK Securities analyst Lee Sang-Hyun told Bloomberg. "Still, the company's sales are expected to recover."
The world's fifth-largest automaker has also struggled to meet shifting consumer demand for sport-utility vehicles, which have been growing in popularity thanks to their family image, Lee said.
Both domestic and international sales sank during the quarter, with 1.02 million cars sold abroad, down 3.6 per cent from a year earlier, and domestic sales sinking 3.7 per cent due to growing competition.
