BMW Carbon Technology

The i3 and the i8 are both built using new carbon fibre technology developed in the US together with a hitherto relatively unknown company at a facility in Moses Lake in Washington State.
"Carbon fibre technology will fundamentally change the car industry, becoming increasingly important in the quest for lighter-weight materials to reduce fuel consumption and lower CO2 emissions"

Carbon fibre composite material has long been used by the aerospace industry, for instance in nearby Seattle where plane maker Boeing has huge factories, as well as in big budget Formula 1 racing cars.
But with few exceptions, it has not been used by mainstream automotive companies, largely because it has been deemed too expensive.

This has now changed, thanks to SGL Group's carbon fibre products, which are not only affordable but also eminently flexible in the way they are produced.
Products made in a process that weaves a cellular carbon honeycomb into carbon fibre reinforced plastic mats can easily be shaped into slim-line seats or sleek body panels, such as doors or bonnets, or even into strong structural support beams to support a vehicle's rigidity.

It is also massively rigid, as well as ultra-lightweight; 30% lighter than aluminium and half the weight of steel.
"Carbon fibre technology will fundamentally change the car industry, becoming increasingly important in the quest for lighter-weight materials to reduce fuel consumption and lower CO2 emissions," the company says in a statement.

BMW carbon fibre car launch

Next week, at the Frankfurt motor show, BMW will be showing two futuristic vehicles that will reflect much of what the movement stood for.
The BMW i3 and the BMW i8 are both contemporary concepts of what the German carmaker envisions the future will require. Both will go into production in 2013.

The i3 is a small, electric city car that seats four, designed for tomorrow's burgeoning mega-cities.
The i8 is a fast, aggressive supercar, powered by a petrol-electric hybrid engine and set to appear in Tom Cruise's next violent Mission Impossible film.

The cars, which were first revealed at a media preview event during the summer, are very different in many ways.
But what makes them interesting is what they have in common - namely their shared technological characteristics.

BMW Laser Headlights

BMW is working on laser-powered headlights that could debut in vehicles "within a few years", BMW announced Tuesday.
"After LED technology, laser light is the next logical step in car light development," the company said in a statement.

The BMW laser diodes powering the next generation of headlights will have an intensity that is 1,000 times greater than conventional light-emitting diode, or LED technology but consume only half the energy.
Laser diodes will also be about 100 times smaller than the small, square-shaped LED cells.

While it would theoretically be possible for BMW to reduce the size of headlights using laser diodes, the german carmaker says it currently has no plans to do that.
Instead, "the size advantages could be used to reduce the depth of the headlight unit, and so open up new possibilities for headlight positioning and body styling," BMW said.

The light from the laser diodes is blue but will be converted into a pure white light that is "suitable for use in road traffic,” BMW said. This conversion also makes the laser light safe for humans and animals.
The laser headlights are expected to make their first appearance in the BMW concept vehicle, the BMW i8.
