Bisimoto tunes Hyundai Ioniq SEMA show car for efficiency, not power

But this year, the company tried something different, building a Hyundai Ioniq hybrid not for power, but for fuel economy. According to Hyundai and Bisimoto, the resulting HyperEconiq managed to repeatedly exceed 80 mpg, based on 83 tests by the tuning company. That's a seriously impressive gain considering the standard Ioniq hybrid is rated at 57 mpg city and 59 mpg highway.

Bisimoto was able to do this by enhancing just about every aspect of the car inside and out. But the most obvious changes are on the outside. The HyperEconiq features a custom body kit with front and side splitters, and a rear spoiler. There are also some prominent wheel spats, something we haven't really seen since the first-generation Honda Insight. The car also features lightweight, one-piece carbon fiber wheels from Carbon Revolution, and they're shod in high-silica low rolling resistance tires. Aluminum brake calipers further lighten the car, and coilover suspension lowers the car for better aerodynamics.

There are a few other mechanical changes under the skin, too. The engine features unique low-friction 0W20 oil from PurOl. It has also been tweaked so that more air can be pulled in during valve overlap, and the exhaust was upgraded to improve exhaust flow out of the engine.

The overall look is rather attractive. The body kit makes the car look sportier and more aggressive, and the carbon wheels are a nice accent to the dark gray color. We're still undecided on the looks of the wheel spats, but if they're functional, it's hard to argue with them. It will also be interesting to see if hypermiling upgrades enter the aftermarket mainstream.
