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.

The hot hatch without a hatch | 2017 Audi S3 First Drive

The 2017 Audi S3 is a car without equal. That might end up on a billboard, but it's actually meant quite literally, as in the S3 has no direct competitor. Other compact luxury sedans, of which there are few, can't match its performance. The BMW 2 Series has two doors, plus it's rear-drive. The bonkers Mercedes-AMG CLA45 is on another power and price planet altogether. The mechanically related VW Golf R isn't a luxury car and has a hatch instead of a trunk. And so the S3 exists as an oddity. But it's a fun oddity, and a well-made one too. For 2017, it receives a number of noteworthy changes to keep it fresh and technologically relevant. Most also apply to the 2017 Audi A3, the car on which it's based, which itself gets a new 2.0-liter turbo four base engine in place of the old 1.8-liter. Paired with front-wheel drive and essentially a variation of the Quattro model's carry-over 2.0-liter, it produces 186 horsepower (up from 170) and returns 29 mpg combined (up from 27). That revamped A3 wasn't on hand for the press drive in Durham, North Carolina, so we were not-at-all stuck with the 2017 S3. Its own 2.0-liter turbo four is unchanged, still pumping out 292 hp and 280 pound-feet of torque through a six-speed DSG dual-clutch automatic transmission. Audi says it'll hit 60 mph in 4.7 seconds, which is a full second quicker than the 220-hp A3 Quattro as well as about a half-second quicker than the Audi A4 Quattro. That bonkers CLA45 is around the four-second mark. Indeed, having so much power in such a small sedan is a novel and grin-inducing experience. The throttle response is sharp enough in standard mode, but tap the dash-mounted Audi Drive Select toggle to choose Dynamic, and it comes even more alive, eagerly shooting the S3 forward with the merest hint of a toe wiggle. The DSG is also quite happy to downshift when called upon, either by said toe or by itself when under braking. Blipping down two gears when heading into a corner is commonplace here, as are the sharp little barks that emanate from the S3's quad exhaust tips. And then there's the S3's Quattro all-wheel drive, which has been updated for 2017 with the same performance-oriented system found in the TT and TTS. Although its front/rear torque split is constantly changing based on current traction conditions, it nevertheless skews towards a rear torque bias to the point that, when in Dynamic mode, it won't reduce power in oversteer situations.

Mixed sales results, but automaker stocks rise on need for cars in Houston

DETROIT — The Big Three Detroit automakers on Friday reported better-than-expected August sales and issued optimistic outlooks for demand as residents of the Houston area replace flood-damaged cars and trucks after Hurricane Harvey, sending their stocks higher. General Motors, Ford and Fiat Chrysler posted mixed August U.S. sales, with GM up 7.5 percent and Ford and Fiat Chrysler down. Japanese automaker Toyota improved sales by nearly 7 percent, while Honda fell 2.4 percent. Still, analysts focused on the potential for Detroit automakers to cut inventories and stabilize used vehicle prices as residents of Houston, the fourth largest city in the United States, are forced to replace tens of thousands, perhaps hundreds of thousands, of vehicles after the devastation from Hurricane Harvey. Mark LaNeve, Ford's U.S. sales chief, told analysts on Friday that following Hurricane Katrina in 2005 "we saw a very dramatic snapback" in demand. That said, Ford sales fell 2.1 percent in August. It sold 209,897 vehicles in the United States, compared with 214,482 a year earlier. Sales were down 1.9 percent in the Ford division and off 5.8 percent at Lincoln. Demand was down for cars, crossovers and SUVs. It was not clear how many vehicles in the Houston area will be scrapped, LaNeve said, saying he had seen estimates ranging from 200,000 to 400,000 to 1 million. Ford's Houston dealers may have lost fewer than 5,000 vehicles in inventory, he said. Ford is the No. 1 automaker in the Houston market, with 18 percent share, according to IHS Markit. The company plans to ship used vehicles to Houston dealers and has "every indication we would have to add some production" of new vehicles to meet demand, LaNeve said. Investor concerns about inventories of unsold vehicles and falling used car prices have weighed on Detroit automakers' shares most of this year. Now, automakers can anticipate a jolt of demand from a big market that is a stronghold for Detroit brand trucks and SUVs. "It's got to be a positive for the industry," LaNeve said. Investors appeared to agree. GM shares rose as much as 3.3 percent to their highest since early March. Ford increased 2.8 percent at $11.34, and Fiat Chrysler's U.S.-traded shares were up 5.2 percent $15.91, hitting their highest in more than five years. GM reported a 7.5 percent increase in U.S. auto sales in August, helped by robust sales of crossovers across its four brands.
