Mazda has announced that the upcoming CX-5 SUV arriving this spring will debut a Smart City Brake Support (SCBS) system, which helps a driver to avoid a frontal collision when driving at low speeds in the city or in slow traffic.

The system uses a laser sensor to detect a vehicle or obstacle in front and automatically reduces the extent of the brake rotor travel to quicken braking operation. If the driver fails to perform any operation to avoid a collision, such as applying the brake, SCBC automatically activates the brakes and reduces the engine output at the same time. Not exactly new hat, the tech, but it is for the brand, and the CX-5 will be the first to wear it.

In related tech news, the company has announced the development of a new resin that offers the same rigidity as conventional materials, with the result being that less material is needed to make a part, while offering the same structural integrity.

Jointly developed with Japan Polypropylene Corporation, the new resin thus offers a lighter manufactured part. It’s set to feature as material in the production of front and rear bumpers, where it contributes to a weight reduction of approximately 20%.

The company blended two components found in polypropylene and rubber (the constituents of resin) that have different properties, and succeeded in distributing them in a double-layer structure in line with the required function for the surface and the inside of the base bumper material. The net result is a bumper with an inner section that retains high rigidity and impact absorption, with reduced thickness.

Additionally, the use of the material also offers faster build times. In the production process, the reduced thickness allows for a shorter cooling period for molding, and bumper molding time, previously 60 seconds, will be halved to 30 seconds utilising the resin, leading to major reductions in the amount of energy consumed in the production process. Needless to say, the resin will be used for the CX-5’s bumpers.
