US diesel model count to double for 2014?

While diesel cars are popular on most other continents, these less-complex alternative to hybrid-electric vehicles have yet to gain major traction in the US. As an increasing number of light cars and trucks start to offer these fuel-efficient engines, though, sales are expected to climb as well. While BMW, Mercedes-Benz and the Volkswagen Group (Volkswagen, Audi and Porsche) continue to lead the way, more non-German automakers like Mazda, Nissan, Chrysler and General Motors are starting to get serious about diesel in America.
TheDetroitBureau.com reports that the 2014 model year will see the number of diesel vehicles offered in the US double to about 40 nameplates, but the news gets even better for fans of these torquey and efficient powerplants. LMC Automotive has released data about future expectations of diesel cars in the US, and it predicts that sales should be very close to one million units in 2015 (up from an expected 600,000 units this year). By 2018, LMC's calculations suggest that sales will more than double from this year's expected totals accounting for almost 8 percent of new light-vehicle sales.

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.

Audi Quattro concept production hopes still alive, could be more radical

Remember the gestation period of the Lexus LFA, the one that, in automotive time, took so long that its origins could have been carbon dated? We feel like it's deja vu all over again, as Yogi Berra would have said, this time featuring the Audi Quattro and Audi Sport Quattro. It was 2010 when our cameras first glimpsed the Audi Quattro Concept (pictured right) at the Paris Motor Show, and we tasted its turbocharged 2.5-liter, five-cylinder powerplant not long after. Last year we met the hybrid, 700-horsepower Audi Sport Quattro concept at the Frankfurt Motor Show, but we got no closer to finding out if there'd ever be a version we could buy. A report in Autocar keeps the flame of hope burning, quoting Audi design chief Marc Lichte at the LA Auto Show saying, "We are working on Quattro, it is still alive." Lichte went on to say, however, that the next imagining is "more extreme" than those we've seen, and, "There will be surprises." Those words alone are a surprise. The last we heard about the Quattro revival was Audi boss Ulrich Hackenberg saying he wanted a more accessible homage to the original, and we don't know how "more extreme" jives with that. Seeing that Audi is serious about the idea, at least, we shouldn't have to wait long to find out. Just don't get your hopes up about its affordability yet.
