MPV segments have been in decline for some time, with many manufacturers choosing to replace MPVs with SUVs.
The Stonic is not a replacement for the Venga, but Kia's European COO Michael Cole said the Stonic's arrival made it "difficult to justify a next generation" for the Venga.
"The MPV segment is in constant decline," said Cole. "As it has shrunk and people have come out, it's actually created an opportunity for us and sales are going fine for us now.
"But there's no final decision on a replacement. It will run for a couple more years, we might limit production, but it'll get very difficult. People are getting what they want in a CUV (crossover utility vehicle) or an SUV instead of an MPV."
