Mazda First Automaker to use 1,800 MPa Ultra-High Tensile Steel In Bumpers

HIROSHIMA, Japan—
Mazda Motor Corporation, in collaboration with Sumitomo Metal Industries, Ltd. and Aisin Takaoka Co., Ltd., has become the first automaker to successfully develop vehicle components using 1,800 MPa ultra-high tensile steel. The super strength steel will debut in the all-new Mazda CX-5 crossover SUV that will commence its global launch in early 2012.
Mazda's new production technology uses 1,800 MPa ultra-high tensile steel to fabricate bumper beams, which fit inside the front and rear bumpers and mitigate damage in the event of a collision. The bumper bars are 20 percent stronger and 4.8 kilograms lighter than previous versions and are a key part of Mazda's next-generation, lightweight and highly rigid vehicle architecture. The new body architecture was developed as part of Mazda's breakthrough SKYACTIV TECHNOLOGY program and incorporates a new energy absorbing structure as well as an expanded use of high tensile steel to reduce weight.
The use of high tensile steel enables vehicle parts to be thinner yet still retain the same degree of strength. This leads to significant savings in vehicle weight. Reducing the weight of bumper beams is particularly important because, as they are incorporated into the body structure at the farthest point from the vehicle's centre of gravity, their weight has a considerable effect on dynamic performance and responsiveness. They must also be strong to provide sufficient collision protection. For these reasons, a method of mass producing the parts using stronger steel has been highly sought after.
However, stronger materials are less pliant and therefore absorb less energy in a collision. To overcome this, Mazda conducted extensive research into how bumper beams deform in a crash, and created a new design that absorbs energy more efficiently. Additionally, in order to ensure the bumpers provide maximum strength in the CX-5, Mazda collaborated with Futaba Kogyo Co., Ltd. to optimize the welding techniques and establish a reliable manufacturing process.
Going forward, Mazda remains committed to reducing vehicle weight and improving dynamic performance while also maintaining a high level of body rigidity and excellent crash worthiness, in order to provide all its customers with driving pleasure and outstanding environmental and safety performance

. They are not about to re-engineer anything on a car from the past without serious safety or legal reasons.Regarding CX-5, I would think April of next year. Not too far away my friend. The diesel version is a slight wait though.

Then this GEM...
Mazda last year announced it had done a deal with Toyota to produce cars using a Prius-style Hybrid Synergy Drive under licence from its big Japanese rival.
This system will be powered by a SkyActiv-G engine, and will go into production in 2013.
But Mr Saruwatari said the vehicle to receive the hybrid powertrain would be sold in only two markets – Japan and one other – as a test case.
“We need some technology knowledge from hybrid,” he said.
Mazda reportedly has no plans to produce a more widespread hybrid-powered vehicle before 2015
Good god I hope not...WHY would Mazda even bother with this rubbish...Bloody Hybrids are just an abortion of a product...and I don't care who makes them.
Why do Americans even buy this crap...WHAT do YOU REALLY SAVE....??
