2012 Mazda CX-5 introduces ultra-high tensile steel components

Article by Christian Andrei, on October 8, 2011

Mazda Motor Corporation is the very first automaker to successfully produce automobile parts utilizing 1,800 MPa super-strength steel. This ultra-high tensile metal will be first launched in the brand new Mazda CX-5 compact crossover sports utility vehicle which will go on sale next year. The company's new production technology employs 1,800 MPa ultra-high tensile steel to construct bumper beams, which fit within the front and back bumpers and reduce destruction during an accident. The bumper bars are 4.8 kilograms lighter and 20 percent more robust compared with prior variants.

They form an integral component of Mazda's next-generation, lightweight and extremely strict automobile structure. The new body-architecture was created as part of Mazda's innovative SKYACTIV Technology program. In addition, the CX-5’s bodyshell incorporates a new energy absorbing framework and broadened utilization of high-tensile steel to lower weight.

The latest bumper beams were created in cooperation with Aisin Takaoka Co Ltd. and Sumitomo Metal Industries Ltd. The usage of high tensile steel allows automobile components to become thin but still keep the same level of durability as previous, thicker pieces, resulting in substantial cost savings in terms of car weight.

Lowering the weight of bumper beams is very essential, as they're integrated into the body framework on the farthest point away from the automobile's center of gravity and outside of the wheelbase.

Moreover, their weight has a significant impact on responsiveness and dynamic performance when added to the polar moment of inertia. They should also be adequately sturdy to give greatest protection during collision. For these reasons, creating a method of mass-producing components using more robust or ultra-high tensile steel has become a top priority.

The new Mazda CX-5 is turning out to be a delightful and compelling proposition that those looking for compact crossover cannot refuse. After all, in terms of driving enjoyment, sustainability and safety, the Mazda CX-5 offers them all. It is the latest embodiment of Mazda’s Jinba Ittai, referring to the overall feeling of oneness between the vehicle and its driver.

Interestingly, the new CX-5 compact crossover is the first Mazda model to be laden with a complete range of brand-new SKYACTIV technologies, making it more efficient, lightweight, more eco-friendly and more enjoyable to driver and ride. Thus, it represents the pioneer model among a new generation of Mazda vehicles developed using the carmaker’s innovative approaches to vehicle design, engineering and manufacturing.

These approaches have allowed SKYACTIV's creators to resolve seemingly incompatible objectives by creating a line of engines, transmissions, bodies and chassis. In developing the new CX-5, people at Mazda focused on four specific attributes: sustainability in terms of safety and environmental imprint; appealing design; interior functionality and craftsmanship; and responsive yet predictable driving dynamics.

As the latest iteration of the Mazda’s Sustainable Zoom-Zoom, the new CX-5 responds according to the driver’s wants and expectation. This is primarily thanks to Mazda CX-5's SKYACTIV powertrains that do not only provide more torque, but are now more responsive and more fuel efficient. This is also thanks to the fact that Mazda is strongly implementing its lightweight strategy, with an aim of cutting the weight of its new generation models by around 100 kg.

Of course, Mazda engineers also sought to augment the strength and safety of these new generation models. Safety is well-provided for by the fact that the body and chassis of the new Mazda CX-5 have been redesigned to provide remarkable passive safety.

In addition, the new Mazda CX-5 is loaded with an array of active safety systems previously not available on the segment. Not to forget that fact that Mazda provided drivers of the new CX-5 with an exceptional field of vision.
