Summary:
First Gen automative steel: DP steel, CP steel, TRIP steel what every car has nowadays.
Second Gen automative steel: TWIP steel, too expensive to beused on cars
Third Gen automative steel: started developing in 2007 in USA and China, tested in 2009. Will be introduced and applied in 2014 VW models in China
Cost: A compact sedan using 3rd gen will cost 240EURO more than 1st gen
Fuel Efficiency: 5% less
Safety: 2x better (as they claim)

The China Iron and Steel Research Institute Group announced in Beijing on Feb. 21 that it took the lead in successfully developing the third generation of automotive steel and applied this technology into the industrial products trial stage.
According to the group, the newly-developed material is expected to be applied commercially in 2014 in China by some automakers, including Beijing Hyundai and FAW-Volkswagen, a major passenger sedan manufacturer jointly ventured by First Automobile Works Group Corporation of China and Volkswagen AG, Audi AG and Volkswagen Automobile (China) Investment Co., Ltd.
As the largest auto producer in the world, China manufactured around 18.3 million cars in 2010, which has meant an increasing number of traffic accidents. According to data from the Traffic Management Bureau, there were 99,000 traffic accidents in the first six months of 2010, which killed 27,000 and caused 117,000 injured as well as 410 million yuan of direct property loss.
"After the application of the third generation of automotive steel, it is more likely for drivers to survive in the accident," said Weng Yuqing, an academician from the Chinese Academy of Engineering.
Weng said at present, basically all cars in the world were made of the first generation of automotive steel. The third generation steel possesses high strength and high ductility, which he said was two times better than the first generation in terms of tensile strength and extensibility.
^ That is a HUGE difference. Let's see some test results. For all we know the info's cooked. This IS China after all.
The thing is that we may not see the overall effects of this (other than possibly weight reduction), since you can bet that car manufacturers will probably start using thinner sheets too, if this were true.
So, if you crash a Chinese car you're only going to be horribly injured and not guaranteed dead. It'll be interesting to see how it goes though, new technology is always nice.
LOL. 99,000 accidents and 27,000 dead. So basically 1 in 3 accidents result in a death? WOW. Just WOW.
Besides, it's not really the strength of the steel that's the most important. It's how it's shaped and formed that gives the final structure (vehicle body) it's strength. Posted via RS Mobile
True enough. Depending on what they mean by 2x safer though. If it meant that the same amount of material could absorb twice the usual force of impact, then using the same design, crap or otherwise, would result in a car that's twice as safe. Otherwise you could use x amount less material for a car with the same crash ratings. Given the price difference between 1st and 3rd gen you'd have something between the current steel chassis and, say, aluminum or cf for a relatively low price.
