Coming up in just a few short days will be the official reveal of Hyundai's Sonata Hybrid Blue Drive, along with a high-line 2.0 liter turbocharged Sonata.
The HBD's power mill is rumored to be the Sonata's 2.4 liter unit (usually making a naturally-aspirated 198 horsepower) hooked up to a hybrid system that uses LG Chem's air-cooled lithium polymer batteries. Why are they so speacial?
