The least costly Sorento is the Sorento Si, which has cloth-covered seats, 17-inch wheels, and the features common to all Sorentos.
For about the same price, you can have an Si Limited, which has seats trimmed in a mix of real and fake leather, and a nicer steering wheel. Wheels are an inch bigger at 18 inches and mount lower profile tyres, which slightly sharpen the steering and look sportier.
Paying more for a Sorento SLi gets you a smart key and pushbutton start (which let you unlock and start the car with your key kept safely in a pocket or bag). Like the Si Premium, the SLi has 18-inch wheels and leather on the seats – but in addition the driver’s seat is power adjustable. You get a hands-free power-operated tailgate, the sound system is better, and taillights use very long-lived LEDs.
Spending more again on the Sorento Platinum adds power adjustment to the front passenger seat, and a memory for adjustments to the driver’s seat (which makes it easy to restore your settings after a companion has driven the car). The front and second-row seats are heated, as is the steering wheel, and the front seats are ventilated. There is a big, power operated sunroof that opens above the first two seat-rows. Very bright HID headlights abet the cornering lights by shining into turns as you enter them. Wheel size increases a further inch, to 19 inches.
The Platinum also brings you an active safety suite that includes automatic emergency braking, a blind spot monitor, lane change assist, lane departure warning, rear cross-traffic alert, and smart cruise control.
The most expensive Sorento is the GT-Line, essentially a Sorento Platinum with more flamboyant styling. The key functional change is the addition of paddle shifters, which allow you to control the auto gearbox from the steering wheel. Aesthetic changes include red brake calipers and red leather interior trim.
