I got the full set of Kia spec sheets for the 2019 model when I decided on that. Every comparison is listed which helped with my selection of a '4'. Fuel was a no brainer as I detest diseasels, and I intended upgrading to LPG (still 57.7p/litre at Morrison's).
If you need them, pm me with your email address, and I'll send them over. I also got some other models - Niro, - not big enough , Picanto - t'other half bought one - same year specs.
