Kia Sorento Plug-In Hybrid Road Handling Review: Pacific Northwest Winter Edition
Sounds like the kind of driving conditions we all dream about, right? Well, that might be a stretch but until recently, I hadn’t actually gotten to do too much driving in harsh conditions in our Sorento PHEV. To be clear, it isn’t that I want to drive in challenging conditions, but I do want to know how well our Kia can handle inclement weather and road conditions in the Pacific Northwest where we live. It’s the principle of knowing what to expect, from the vehicle, when things get ugly outside. It is also useful to get practice driving in such conditions now and then too, so I don’t grow complacent and lazy about the more challenging aspects of driving in inclement weather.
So how bad were those driving conditions? This time, it wasn’t about snow and or ice (which I tend to use the Kia’s Snow Mode for), but rather an excess of water. The highways and rural two lane roads were mostly drenched in either a steady downfall or an outright deluge. In multiple places I had to drive through standing water, including one spot where it was at least 6 inches deep (this was on a slower stretch going through a small town on the way to our destination). Mostly the standing water was just puddles and or streams of water draining down or off the highway, but at no point did I experience any loss of traction. In terms of grip, it felt like we might as well have been on dry pavement as Kia’s AWD and the Blizzak snow and ice tires handled these conditions with aplomb. Honestly wet handling was the main reason I bought Blizzak tires instead of the Michelin X-ice snow tires I have purchased for other vehicles (they don’t seem to have the best wet road handling and are acceptable at best). This being the case, I highly recommend that anyone living in a region with extreme winter weather conditions consider investing in quality traction tires that are appropriate for your weather (be that lots of snow or lots of rain, or both as in our case). Of course there’s no replacement for driving safely too, especially adjusting your driving for conditions as warranted.
Here’s more detail about our drive in these appalling conditions: For the longest side trip (108 miles) I had 850 pounds or so of people and cargo in the vehicle and I managed to cover about 31 miles in electric only (EV) mode (16 going and 15 coming back). My tires were inflated to 39 psi, cold (or about 42 warm). I have my roof racks on still, but no cargo box and the speed limits when not passing through small towns were 40 - 60 MPH. I stayed within 3 MPH of the speed limit for most of the drive. I didn’t use cruise control (with the flowing water on the runway that would have been a little dangerous). Outside temps were in the low 40’s to low 50’s F and the worst visibility I had at some points was about 300 feet due to low clouds/fog and heavy rain. I got about 2 MPG better fuel economy on the return leg than outbound, but for the entire 108 mile trip my blended average MPG was 37.6 which I consider to be quite impressive considering the full load, snow tires, and conditions of the drive. That is very close to similar trips I would have taken in summertime on my all season tires. I feel that my slower speed was the key to great fuel efficiency results.
At the end of our family holiday visit, we charged up the hybrid battery again and headed home the next day. Quite surprisingly, on the 59.2 mile trip home (we went a slightly different route) I managed to achieve 74.2 MPG, blended (EV and HEV). Also note that I used “Automatic” mode for about ⅔ of the trip home and only switched out of it when I noticed it wasn’t switching into EV mode on downhill stretches or flat sections, it just kept me in HEV mode from about 10 miles into the drive. I figured it was not going to use up the remainder of the battery before we got home so I wanted to force that change. It is possible the automatic mode would have changed to EV mode again, before I got off the freeway but I don’t think the algorithm is smart enough to know where I am going and when exactly to switch in order to use up the hybrid battery charge just before/as we arrive; I believe it just goes off of sustained speed, and how hard one accelerates. I’ll do more testing of that setting in particular, in the future. For reference, my guess on when to switch back to EV mode resulted in using up the battery about 1 mile before we reached home (missed it by that much!).
