Their first step is a new line of "Blue" vehicles which are essentially existing models in Hyundai's lineup optimized for fuel efficiency. Hyundai plans to offer lower priced Accents and Elantras with modifications to aerodynamics, gearing and tires to improve fuel economy. Direct injection will also be utilized in new Hyundai models and by 2011, a hybrid Sonata will be released. The hybrid powertrain, called, "Blue Drive" is a smaller, lighter, parallel system which Hyundai believes will out perform the Toyota Camry Hybrid.
By 2013 Hyundai expects to have a plugin hybrid on the road, but whether it will be an adaptation of a current model or a completely new offering is unknown. One thing is certain: Hyundai will be a significant player in putting more fuel efficient vehicles on the road.
