Why do Kia and Hyundai offer different length warranties for cars that are co-developed?

Am I right in thinking that Hyundai has a significant ownership stake in Kia? I'm trying to understand why one brand offers a five-year warranty while the other offers a seven-year warranty on cars that are co-developed. Is it merely an exercise in differentiating the brands? Do your readers provide evidence that Hyundai cars are just as reliable as the Kia counterparts, but just don't have such a long manufacturer warranty offered as standard? I see that the Hyundai seem to be a shade less expensive in the low to mid range, so is this the trade-off?

Same conglomerate split apart by Monopoly legislation in South Korea, so operating as two separate companies. In the UK, Kia offers a seven-year warranty up to 100,000 miles (excluding taxis). Hyundai offers an unlimited mileage five-year warranty (excluding taxis). So if you are a high mileage driver, the Hyundai warranty makes more sense. We get very few complaints about both manufacturer's vehicles.
