That's really impressive. Actually, I'm impressed with Hyundai's whole lineup these days; they're the only manufacturer with air curtains and grill shutters on every model, and the packaging on the Sonata plug-in is quite impressive--no loss of trunk space compared to the non-hybrid.

Someone at the university here--I'm guessing in the chemistry department--has an Ioniq with the license plate "CVLNT."

Excellent! I'm likewise consistently impressed with Hyundais. It's numbers like that which are at least partly responsible for that.

Hyundai is an excellent car maker. Rented a 2012 or 2013 Sonata a few years ago (for work), and that auto gear box was amazing. Sixth gear sat way down at like 1900 rpms at 55 mph or something like that. Just loved the car all around too.

That's right. I remember now trying to figure out how close to right between 1500 and 2000 the tach needle was, IIRC.

I think ~35-38% is probably a fair estimate of that engine's peak efficiency. It's likely to be drastically lower above 3000rpm, however.

Got both a 2013 automatic AND 2016 manual Elantra(same color, too). As you state for your 2017, our 2016 manual is lower geared than the 2013 automatic. In overall driving, their MPG are similar, as the EPA indicates. Just due to their gearing, MAYBE the automatic could get better MPG at higher speed on the highway. But the manual appears very efficient & able to get better MPG, once speeds are less than 55-60MPH & sweeps the automatic away on slow backroads, if the manual can maintain 6th gear. With the lower gearing AND no automatic losses, the manual has spritely acceleration, & is favored on hills & mountain passes. Love both our automatic & manual transmissions..... altho the wife loves only the manual transmission.
