Mercedes-Benz previews its curvy sports-car and design future

Suggesting creases are passe for automotive design, Mercedes showed off ideas for its future styling directions this week at a forum in Germany, including previews of upcoming sports cars and sedans. We see images of a curvy sports car study (the silver car) with huge wheel arches flared out almost like pontoons. There's also what appears to be a rear-engine hypercar (white car); we've been reading reports about it for months. Additionally, there's a red sporty saloon, as Mercedes calls it, also among the photos. It features prominent rounded fenders and a bold horizontal grille. Mercedes also previewed its upcoming A-Class, in what it calls the Aesthetics A sculpture, which looks like a car covered in a red sheet. Though Mercedes says this is its next step to a purer design, creases and strong lines are still evident on the sides. Related Video:

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

Mercedes considering convertible SUV

Mercedes has been focusing a lot of attention lately on revitalizing and expanding its crossover and SUV lineup. So what's next for high-riding Benzes? It could be a convertible. According to Daimler's sport-ute and sports car chief Wolf-Dieter Kurz, the company is closely considering a drop-top SUV of some sort. "We will find a market," Kurz told the Australian website CarAdvice. The trouble is that "the convertible is a very slim niche in terms of the SUV portfolio." The biggest problem could be China, where luxury SUVs remain hugely popular – but where convertibles, by and large, are not. "There are lots of discussions," said Kurz, "but we didn't have any decision yet." The last time Mercedes offered a convertible SUV was with the short-wheelbase version of the Gelandewagen, pictured above. It was available (in some markets anyway) for 34 long years as part of the G-Class lineup, but was discontinued in 2013. That left the Jeep Wrangler and Land Rover Discovery as the only convertible SUVs to speak of currently available. Nissan tried its hand with the Murano CrossCabriolet, but that was phased out as well, while Land Rover prepares to take another stab at it with the upcoming Evoque convertible. It'd be interesting to see what approach Mercedes might take, and where it would position the model. Related Video:
