Audi bringing matrix 'organic' LED concept to Frankfurt

Audi has announced that it's bringing a new concept to the upcoming Frankfurt motor show in September, and now it is teasing the taillights. They adopt organic light-emitting diode technology, which takes advantage of several benefits. For one, it uses a relatively low amount of electricity, between three and four volts. It's also incredibly thin, made up of two layers, each less than a thousandth of a millimeter thick. It casts no shadows, requires no reflectors or any other elements, and emits very little heat. Plus the lights can be formed into different shapes, opening up new possibilities for designers. This isn't the first time we've seen Audi focus on lighting technology, and in recent years it's showcased matrix LED and matrix laser headlights. The company runs through the history of the evolution of its lighting tech in the video above. We'll have to wait a little longer to find out what the team from Ingolstadt will be putting these new taillights on. Audi presents latest lighting technology at the IAA in Frankfurt - Matrix OLED technology makes its debut in a concept car at the IAA - Light attains a new level of homogeneity - Flat light sources open up new design possibilities Audi is presenting its next step in automotive lighting technology at the IAA in Frankfurt. The new Matrix OLED lights enable a previously unattainable level of lighting homogeneity, opening up further creative opportunities for design. As the leading brand in automotive lighting technology, Audi has systematically developed all aspects of OLED technology over the years. Matrix OLED lights combine high-tech engineering and design ideally – initial projects are currently underway to implement OLED technology in production tail lights. They are being shown for the first time in a concept car at the IAA. OLED is an English acronym for "organic light emitting diode." In each OLED unit, two electrodes – of which at least one must be transparent – incorporate numerous thin layers of organic semiconductor materials. A low DC voltage – between three and four volts – activates the layers, each of which is less than one-thousandth of a millimeter thick, to light them. The color is based on the molecular composition of the light source. In contrast to point light sources – such as LEDs – which are made of semiconductor crystals, OLEDs are flat light sources. Their light attains a new level of homogeneity, and its dimming is continuously variable.

Best cars for snow and ice in 2023 and 2024

What's the best car for snow? The real answer is "the one with winter tires." What do we mean by that? You could have the finest, most advanced all-wheel-drive system or four-wheel drive in the world, but if you're running all-seasons (the spork of tires), your fancy four-wheeler won't matter much. The odds are, any vehicle on the road running good winter tires will probably perform adequately in slippery, slushy and/or snowy road conditions. (Here's a more complete explanation of why winter tires are totally worth it). In other words, you don't really need any of the cars on this list. With a set of winter tires, countless others will do the job, and even these will be at their best with proper rubber. You can find a variety of winter tires for your car here at Tire Rack. Keep in mind that you will need a full set of four snow tires for safety and performance, no matter what you're driving. The days of your dad putting just two snows on the family truckster to get it moving in a straight line are long gone. Don't get us wrong, getting a car that performs well in snow and ice is still a worthy criteria for car buyers. According to the U.S. Transportation Department, 70% of Americans live in places that get snow and ice. And much of the country has been blasted with arctic air for much of the new year. So let's look at the cars. First, we're highlighting choices for a variety of buyers and price points. Second, we're not just considering snow; we're considering general wintery conditions people will experience driving to work or school. As such, these are all choices with advanced all-wheel-drive systems, usually with "torque-vectoring" systems that not only automatically shunt power front and back, but side to side between the rear axles. Most have extra ground clearance for getting through deep snow, and we prefer those vehicles with more responsive steering, throttles and transmissions that provide a greater sense of vehicle control in slippery conditions.    Acura RDX Read our Acura RDX Review Acura's Super-Handling All-Wheel Drive system was one of the first to offer torque-vectoring, and besides often being touted for its ability to greatly enhanced dry-road handling, its benefits in the slick stuff can be profound. It's actually surprising that Acura hasn't leaned into this capability further by offering more rugged versions of its vehicles.

The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.
