Hyundai is headed to the Paris Motor Show with a bevy of environmentally friendly models and concepts. In addition to bringing along production-intent vehicles like the new i20, Genesis Coupe and Genesis sedan, the automaker will showcase two new concepts that will also carry its blue theme. Remember, blue is the new green. Anyway, the i20 blue features aero tweaks and low rolling-resistance tires in order to improve its efficiency, but it's the Santa Fe hybrid that's a bit more interesting. That new model features an electric motor that puts out 30kW of power along with a 2.4-liter four cylinder engine. Both powerplants feed their power through a six-speed automatic transmission with revised gear ratios optimized for fuel savings. A 270V lithium-polymer battery pack sends the juice to the electric motor, and it all adds up to 38 mpg in the U.S. and carbon emissions of 148 g/km. We'll be in Paris to see these things up close and personal, so stay tuned.
