And they would be correct. New hybrids like the Ioniq are using much more efficient electric motor drives with Li-ion battery packs to propel themselves and take load off the ICE. There's just too much ICE energy wasted in internal friction, exhaust heat, heat lost in engine cooling, and just the basic operation of an ICE with its pistons that have to change directions totally many times per second. There's just not much more than can be done, and things that are being done (e.g., turbocharging) add cost and complexity and reduce reliability. Electric motors and battery packs are increasing in power while ICE's become smaller and less powerful thus using less fuel.but everyone said we are nearing the end of IC efficiency?
That steady speed MPG pretty strongly suggests the reason the first guy got 87 was because he was running the battery down for most of the drive.
considering it's a much smaller car with a smaller IC engine it's easy to imagine it could rather easily get 80+ mpg like many hypermilers with plenty of mods to their car.That steady speed MPG pretty strongly suggests the reason the first guy got 87 was because he was running the battery down for most of the drive.
90kmh is about 55MPH, and at that speed the ioniq was getting about 60MPG, while an Insight would be getting ~75, plus or minus 5. That being said, fuel efficiency has been creeping up, and it's probably only a matter of time before we have a new car with MPG as good as the Insight for average consumers (this car is pretty close), but for enthusiasts the Insight will still be king.
What I'd like to see is what kind of fuel economy the Insight would get in the same conditions when retrofitted with all the tech introduced since it was released: lithium, active grille shutters, replacing mirrors with cameras for aero, direct injection, etc.
