BMW's new intelligent lighting systems

BMW announces two new and interesting lighting technologies: the first device, the system Dynamic Spot Light, uses an infrared sensor (sensitive to the heat from the bodies) to recognize people or animals that are located 100 meters from the front of the car and it projects a beam of light to alert the driver.

The technology will soon be offered with Night Vision Package. I wonder if BMW has noted that some animals, if dazzled, they tend to paralyze their position until the light is not distract. The same, not dazzled, but could get away from the road heard the noise of the car approaching. However, in theory, a driver sees danger ahead should react faster with benefits in terms of handling and braking.

Volvo soon fly smart to consume -20%

Volvo will soon begin to test the benefits of adopting a carbon-fiber flywheel to the rear axle to reduce consumption by up to -20%, a solution that, according to the Scandinavian home, while providing the feeling of driving a 6 cylinder because the extra power generated by the device. The experimental project will begin in the fall with the Swedish contribution to the energy that has allocated € 740,000 to participate in the development of the second generation of energy recovery systems franante.
