Audi readies sales of new fuel-efficient A4, A5 and A6 models

As diesels continue to account for a minority of cars sold by Audi in the US, the German automaker and Volkswagen unit continues to expand its diesel models in Europe for the sake of fuel efficiency. Early this year, Audi will debut its new A4, A5 and A6 variants in Europe as part of what it calls its "ultra" strategy of pairing performance with fuel economy. Audi will have 11 new models for 2014, and the updated A4, A5 and A6 will use Audi's 2.0-liter turbodiesel powertrain. Versions of that engine will range from 136 to 190 horsepower, while torque will range from 236 to 295 pound-feet. More importantly, the models will get anywhere from 51 to 60 miles per gallon, when tested on the more lenient European driving cycle. And while manual transmission will be standard (this is Europe, after all), the A6 will have a seven-speed automatic transmission option. Pricing will start at 32,600 euros ($44,000 US) for the base A4 and work its way up to 45,000 euros (about $61,000) for the top of the line A6. Last year, Audi boosted its diesel sales in the US by 40 percent to just over 10,000 units, though that accounted for just a fraction of the approximately 158,000 cars the company sold domestically in 2013. Audi has a press release on the new models below. The new ultra models from Audi A4, A5 and A6 with impressive efficiency • New ultra models from Audi with 136 hp, 163 hp and 190 hp • Greater efficiency with unchanged driving dynamics • Emissions of just 104 to 119 grams of CO2 per kilometer (167.37 to 191.51 g/mile) Audi A6 2.0 TDI ultra, Audi A5 2.0 TDI ultra, Audi A3 1.6 TDI ultra Audi is expanding its ultra strategy with 11 new models: Especially efficient engine versions in the A4, A5 and A6 model lines will be launched in early 2014. A new and powerful two-liter TDI will provide the drive at 100 kW (136 hp), 120 kW (163 hp) or 140 kW (190 hp); the engine emits just 104 to 119 grams of CO2 per kilometer (167.37 to 191.51 g/mile) depending on the model. The "ultra" designation stands for sustainable mobility that is fully available for everyday use. With a combined fuel consumption rate of 3.9 to 4.6 liters per 100 kilometers (60.31 to 51.13 US mpg) and CO2 emissions of 104 to 119 grams per kilometer (167.37 to 191.51 g/mile), the new ultra models from Audi are among the most efficient cars of their segment – without any limitation on the driving dynamics or customary comfort.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

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.
