One thing to lookout for with KIA cars is the under stated reading of there MPG on the on board computer. My current car is coming up to 4 years old (KIA Carens heavy tank) and the ship’s computer says its doing 33 MPG but the true MPG is 38 MPG and using a computer program to calculate MPG on every refuel I get 100% accuracy. When I look at the difference between 33 and 38 MPG the maths adds up to the possibility that the cars computer is set to US gallons and my car being only a trim level of 3 out 4 does not have the option to change things like US gal to Imperial gals. There were a lot of users in the KIA Owners forums reporting their cars where set to US gallons on delivery and although with them having trim level 4 were able to change it, for myself I got shrugged off by the dealer saying it is correctly set but the true MPG says different. I would imagine this option is changeable in the new Sportage so worth having a look to see if it might be set to US gallons as the South Koreans think as we speak English we must be in the USA.
Unfortunately my mpg was even worse after doing manual calculation. The onboard computer stated 41.9mpg, but my fill-to-fill calculation is 40.96mpg. Not a massive difference, but unfortunately shows that my car isn’t set to US gallons. This was a 381 mile journey with 95% of it on A roads and motorways. For comparison, my previous car (2016 Golf GT) would have achieved around 57mpg on this journey.
