All of them belong to different classes.
Honda Vezel: Subcompact crossover SUV
Kia Sportage: Compact SUV
Toyota Fortuner: Mid-size SUV
I was talking about local market. Technically, Sportage is in direct competition with Suzuki Vitara, but Vitara is already a failure because of poor brand image and boring interior.
Fortuner is in competition because its a very basic SUV that lacks modern features and comfort. If Sportage can offer those, then people will definitely consider Sportage over Fortuner.
