Hyundai Santa Fe blue Hybrid

One of the models Hyundai will unveil at the Paris Auto Show will be the Santa Fe blue Hybrid. The company plans to sell its first hybrid-electric vehicle in its home market of Korea by July 2009. The gas-electric hybrid technology featured in the Santa Fe blue Hybrid reduces CO2 emissions to 148 g/km and delivers a fuel economy of about 39 mpg.

One of the ways Hyundai is maximizing fuel economy is by using a "start-stop" system that is also found on other economy-minded vehicles. Engine control software automatically shuts off the engine when the vehicle comes to a halt, cutting emissions to zero. When pressure is reapplied to the accelerator pedal, the Integrated Starter Generator (ISG) automatically restarts the engine. The Theta’s engine control software governing injection pressure, engine cycle timing and exhaust retreatment rates has been revised to further reduce fuel consumption.
