U.K. Hyundai Ioniq Review includes EV

Glendale (Ca.) Hyundai said they would be getting the Ioniq sometime in March. Thats the only Hyundai dealer that I called yesterday. If anyone hears about any other dealers getting one before then please let us know.

Just got this in my inbox...will be interesting to see if Tesla decides to match the lifetime battery warranty when the Model 3 hits the streets.

It is only a complete failure warranty. No warranty for range of which they will claim is normal wear.

¹The Lifetime Battery Warranty applies to all U.S. 2017 model-year IONIQ vehicles. The Lifetime Battery Warranty ensures that if the lithium-ion polymer battery fails, Hyundai will replace the battery and cover recycling costs for the old battery free of charge to the original owner. The Lifetime Battery Warranty excludes coverage for vehicles placed in commercial use (e.g., taxi, route delivery, rental, etc.).
 
Are you basing that solely on the text you quoted? I'm curious as to the full warranty verbiage. Even Nissan covers degradation (abnormal, at least).

If it's anything like their Kia division's Soul EV the warranty will guarantee no more than 30% degradation in ten years or 100,000 miles. I suspect the "lifetime" warranty is just against a complete failure and (if like other Hyundai warranties) only follows the original owner.
 
Did Kia/Hyundai resolve the premature cell decay shown during the INL testing? Or is the Ioniq going to have different cells than the Soul EV?

10% loss of capacity in 12,000 miles.

Unfortunately this is largely par for the course for the BEV batteries tested in this manner. These test cars are charged to 100% and baked outdoors in the Arizona heat; the test is as brutal as they come for BEVs .

The Ioniq uses cells from LG Chem while the Soul EV uses sells from SK Innovation. Only time will tell how the LGs in the Ioniq degrade in extreme circumstances but LG cells in the Spark EV and Focus EV degraded similarly to the Soul's SKI cells:

~4% degradation over 4,000 miles (the only data point available)

~9.5% degradation over 12,000 miles

There have likely been some chemistry advancements but I suspect the Ioniq's batteries (when subject to the same conditions) will fare similarly to the other LG Chem BEVs.
