Not an EV, but my 2021 Hyundai Elantra gets around 52mpg on the highway, though it's rated at "Up to 33 city / 43 highway" I've had an overall average of 46m

Not an EV, but my 2021 Hyundai Elantra gets around 52mpg on the highway, though it's rated at "Up to 33 city / 43 highway" I've had an overall average of 46mpg with mixed city/highway driving. Hyundai clearly is doing well with efficiency.

I've liked Hyundai's I've owned in the past for this exact reason. But in case people get a little high on the Hyundai hype in this thread... every Hyundai model before 2019, iirc, is extremely easy to steal. If you live in an auto theft-prone metro area like I used to, I would avoid those cars. Kia as well. IIRC it's so easy that a method of stealing a Hyundai using only a male USB port surfaced on TikTok a few weeks back. But it's been a huge problem in a few major US cities for the past 2+ years.

  I believe this applies to 2020 and 2021 models as well. According to NPR[1] Hyundai/Kia only decided to finally install engine immobilizers part way through the 2021 model year.

  Perhaps there is an up-side to Hyundai's general lack of attention to basic security practices: Apparently it's just as easy to hack the onboard infotainment system. Someone recently published a procedure that allows owners to install a customized Linux ROM using the normal firmware update procedure. Hyundai literally used a default and well known signing key to authenticate their software updates so it's almost trivially easy to circumvent. The details were discussed previously on hacker news, I don't have the link handy but I believe it is possible to (easily) take control of the infotainment screen as well as CANBUS-accessible systems, including the door locks and very likely access all of the telemetry data destined for the dashboard instrument displays. There are probably even more possibilities that I haven't mentioned. I really wish I had more free time to hack on it because I think it would be really fun and interesting.
