The lithium-upgraded Prius Eco is rated 53 for highway MPG. I thought that was impressive until I saw the Hyundai Ioniq blue's score:
59 highway MPG
WOW.
Only the manual-shift Honda Insight ever scored higher (61). Hyundai does it by using an exhaust intercooler to improve EGR efficiency by 200%. They also have two separate water jackets for the block & the head, so the block can run hotter (220), the oil can run hotter, and reduce viscosity losses. Plus each cylinder has multiple holes to inject the fuel where it needs to be. WARRANTY: When your battery eventually needs replaced 10+ years from now, other carmakers will charge you $2500-to-3000 replacement cost. Hyundai warranties their batteries forever (if it's the original owner).
I never imagined an upstart Korean company would be able to out-engineer the Japanese working at Toyota.
