Kia's all-new family SUV has been spotted during development testing, and it looks like Kia is using the BMW X5 as a benchmark.

Photographers have spied what is believed to be the next-generation Kia Sorento, ahead of an anticipated launch in late 2020 or early 2021.

The vehicle shown is heavily disguised, employing both camouflage wrap and false body panels to conceal its final design underneath.

While it's hard to see the finer details, it looks like the Sorento is going to get a squarer, more muscular look than the long and sleek proportions of the current model, likely inspired by the larger Telluride available in the US.

Being a generational update, the Sorento should get an overhauled design inside and out, while also getting a revised architecture that should open the window for electrification – hybrid and plug-in hybrids are mooted.

Expect up to seven seats to be offered as before, but we might see the Kia SUV move upmarket by increasing space available to second- and third-row passengers.

It also appears Kia might be focusing on enhancing the Sorento's dynamics, given the camouflaged prototype can be seen with a BMW X5 following closely behind – it's likely the engineers are using the Bavarian SUV as a benchmark.

A leaked product roadmap obtained by TheKeea indicates the new-generation Sorento will go into production from August 2020. That means we should see the new model revealed shortly before that before going on sale globally in the final quarter of 2020.
