document: Hyundai Shows Off Blue 2 Fuel Cell Concept , Delays Two Hybrid Models Blue 2 offers a vision of the future , while the Sonata Hybrid and Kia Optima Hybrid should hit dealer showrooms within the coming months Hyundai has unveiled a new concept car at the 2011 Soul Motor Show that is called Blue 2 . The car is a mid-size sedan that offers some hints at the future blueprint for mid-size sedans from Hyundai . The car is a FCEV or a Fuel Cell Electric Vehicle that is powered by hydrogen and is an attempt by Hyundai to capture some leadership for the emerging fuel cell vehicle market . There are some huge hurdles for FCEVs though , namely an infrastructure around the world for producing and distributing hydrogen . Hyundai notes that the Blue 2 concept has a stack power of 90kW and a fuel economy of 34.9 km/L . The car has special low-resistance tires and light alloy wheels to reduce weight and help extend the driving range of the car . The concept has LED screen panels on the exterior of the car that allow the driver to see the vehicles status located on the front and rear . The car also has a welcome system that recognizes the driver and automatically opens the door . The concept has no side mirrors , using cameras on the sides mounted on the roof allowing the driver to see behind the car . The dash of the car uses OLED panels rather than normal gauges . While Hyundai is showing off its new concept car , a few details on the production hybrids from Hyundai and Kia have surfaced at Wards Auto . In other Hyundai news , Wards Auto reports that the Hyundai Sonata hybrids have been promised for delivery to the U.S. in later-April . The car has been officially on sale since December of 2010 , but few dealers have actually been able to get the cars in stock . Hyundai reports that the delay in delivery was to give the automaker time to remove a switch that was integrated into the vehicles that allowed the driver to disable a warning system that makes noise to alert blind pedestrians . Wards notes that the car has been criticized by reviewers for having real world fuel economy that is much lower than the published EPA ratings . Hyundai spokesman Jim Trainor says , '' `` The slow rollout has nothing to do with some of the early results that folks got . '' '' `` Even with the early prototypes that were making the rounds last fall -LRB- in California -RRB- , many media got well over 40 mpg on the drive , '' Trainor says , adding `` production units will be better . '' While the Sonata Hybrid is being promised by the end of the month , its kissing cousin - the Kia Optima Hybrid - has been set to go on sale in the U.S. in Q2 rather than the January 2011 launch that Kia originally planned .
