Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.

Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

Recharge Wrap-up: Porsche adds third 919 Hybrid for Le Mans, Audi to heat factory with geothermal

Porsche will be running a third 919 Hybrid LMP1 car in the 2015 24 Hours of Le Mans endurance race. The extra Porsche will race in the six-hour May 2 WEC race at Spa-Francorchamps as a lead-up to the legendary 24-hour race on June 13 and 14. Porsche hasn't announced the driver lineup for the third 919 Hybrid, but drivers will remain the same for the other two cars. Including the third car is meant to help further test performance and efficiency as part of development for future hybrid systems. Read more at Green Car Congress. BMW i Ventures is investing in Zendrive, a driving focused data and analytics company. The cooperation of the two companies is meant to help advance safety and efficiency by making the "in-car mobility experience even smoother by optimizing commuting and driving patterns," according to BMW i's Ulrich Quay. The venture capital arm of BMW's i brand also invests in JustPark, Chargepoint, Life360, Chargemaster and MyCityWay, and says it will have more strategic investment announcements in the coming months.

When the facility is finished, Audi expects to source 82,000 megawatt hours of geothermal energy per year from it, or about six percent of its total heating needs. The clean energy helps Audi move "step by step along a path to developing a CO2-neutral production plant," says Audi's Dr. Hubert Waltl. "The mobility of the future must be CO2-neutral – and that applies not only to the use of our vehicles, but also to their production." Read more in the press release below. Supporters have begun a petition drive for the passage of an E15 ordinance in Chicago. Despite pushback from oil companies, the city council is close to passing the "Chicago Clean Air Choice Ordinance," which includes the requirement by retailers to sell the 15-percent ethanol gasoline blend in the city. The ordinance includes an exception for stations selling less than 850,000 gallons of fuel per year. More than 4,000 people have signed the petition so far, with others leaving messages to voice their opinion on the matter in opposition to Big Oil's attempt to block it. Read more at Domestic Fuel.
