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 34.9km/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 (in California), 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.

Two questions:

#1. Liter of What? Liter of Hydrogen? Liquid? Gas at what PSI?

#2. What testing cycle? (According to the link, the Sonata Hybrid gets 21 km/1 liter)

#3. What is the cost to get to Hydrogen into the car. Hydrogen isn't created as a liquid or a pressurized gas. Its going to take significant energy to turn it into either a liquid or a pressurized gas.

Hydrogen gives up a great deal of efficieny for the sake of "immediate" refueling. The worst part is that a Hydrogen Car is essentially an EREV car with a Hydrogen Fuel Cell Extender. For the cost increase of the Hydrogen Fuel Cell Stack, one could put in a much larger Plug-in Battery and simple BioFuels/NG Extender.


Hydrogen Fuel Path
Electricity --> Hydrogen (Using Electrolysis today is ~60% efficient)
Hydrogen Gas --> 5000 psi Gas (Compression is around 90% efficient)
5000 psi Gas --> Electricity (Fuel Cell is less than 50% efficient when put through varying load conditions)
Electricity --> Forward Motion (Electric Drivetrains are around 95% efficient)

Overall Pathway is ~25% efficient. Using NG as the source material helps... maybe get up to ~30% efficient.

(The Honda Clarity goes 60 miles on 1 kg of Hydrogen. To get 1 kg of Hydrogen, one needs to expend ~65 kWh of electricity or ~55 kWh of NG for ~.92-1.1 miles per kWh)

Electric Path
Generation-->Home (Tranmission 93% efficient)
Home --> Battery (Charging 84% efficient)
Battery --> Forward Motion (Drivetain of Tesla 92% efficient)

Overall Pathway is ~72% efficient... for a car you can buy today (Its possible with better charging and electronics, its more like 85% possible). Its true if use NG as the source, your looking at more like 40% efficient... but thats also better than the Hydrogen pathway.

(The Leaf goes 100 miles on 34 kWhs from your wall. This requires ~37 kWh of source electricity or ~62 kWh of NG... this is 1.6-2.7 miles per kWh)

thats 3 questions...

also I love how when something isnt going to work everyone trots out that old standby... efficiency. Oh the gasoline engine is very inefficient we should all use electric cars because they use 92.283928342% of their power to move the vehicle and dont emit any horrible co2 gasses *pushes up nerd glasses*... Meanwhile in the real world your puny EV is stuck on the side of the road waiting for a battery truck to come along and save you with an 8 hour recharge and Im flying by in my gasoline powered 150 year old technology hydrocarbon powered vehicle. Have a nice day!
