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.

Fastest and most powerful SUVs in America for 2022

Here in the United States, we enjoy power almost as much as we like our SUVs. Thankfully, we’ve got plenty of both. Traditionally, the most powerful SUVs source their massive horsepower and torque from some form of a V8. While thatÂ’s still generally the case, electrification comes into play more and more, whether itÂ’s mild-hybrid tech, a plug-in hybrid powertrain or, as is the case with the two vehicles topping this list, fully electric vehicles. As we enter the 2022 model year, letÂ’s look at the most powerful SUVs available.  Before we dive in, letÂ’s address the elephant that is waiting just outside the door. Due to supply shortages, Mercedes-Benz is shelving most V8 models for the 2022 model year. Some 2021 models can still be found in dealer inventories, but we wonÂ’t include them. With that in mind, letÂ’s dive into the list. 2022 Audi RS Q8 — 591 hp / 190 mph Read our review of the Audi RS Q8 The only Audi on this list is a hot little number, which we characterized as “an uncompromising option in a field of compromised options.” Powered by a 4.0-liter twin-turbo V8 (which seems to be a popular format in this list), its 591 hp and 590 lb-ft of torque get it scootinÂ’ to 60 mph in just 3.7 seconds, and on to a top speed of 190 mph. It even has the bragging rights of holding the Nurburgring lap record for an SUV.   2022 Rolls-Royce Cullinan Black Badge — 592 hp / 155 mph (limited) Read our review of the Rolls-Royce Cullinan This is one SUV where being a passenger might be more exciting than sitting in the driverÂ’s seat, thanks to over-the-top luxury — what do you expect from a car that costs over $350,000? The driver doesnÂ’t go unrewarded, though, with a turbocharged 6.75-liter V12 at their disposal. Thanks to the Black BadgeÂ’s software upgrade, it makes 592 hp and 664 lb-ft of torque to help get to its electronically limited top speed of 155 mph that much quicker.    2022 BMW Alpina XB7 — 612 hp / 180 mph Read our review of the BMW Alpina XB7 Alpina takes already impressive BMW vehicles and turns them into even more powerful, more luxurious machines. The Alpina XB7 improves upon the BMW X7 with a biturbocharged 4.4-liter V8 offering up 612 hp and 590 lb-ft of torque. ThatÂ’s good for a 4.0-second 0-60 sprint and a 180-mph top speed. Alpina also adds its own transmission and drivetrain tuning, upgraded suspension, exhaust and a whole slew of unique appearance touches.

Audi TT Offroad concept packs 408 hybrid horsepower, yet returns 123 mpg

Audi took the wraps of its TT Offroad Concept at the Beijing Motor Show, after teasing us with sketches earlier this month. "The Audi TT offroad concept provides a glimpse of how we might imagine a new model in the future TT family," says Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development. "It combines the sporty genes of the TT with the strengths of a compact Audi SUV."
The latest in Audi's eTron show cars reminds us an awful lot of the the Audi Allroad Shooting Brake concept that debuted a few months ago at the Detroit Auto Show. In addition to very similar physical appearances, the two share the same plug-in hybrid propulsion systems (the "plug-in" part is a bit misleading, as the concept simply needs to be parked over an inductive pad to take advantage of Audi Wireless Charging technology).
Proving that hybrid power never has to be a compromise, the TT Offroad Concept packs a 292 horsepower turbocharged 2.0-liter four-cylinder under the hood. The combustion engine is assisted by two electric motors (rated at 40 kW at the front and 85 kW at the rear) to provide a total system output of 408 horsepower and nearly 480 pound-feet of torque. With all-wheel drive, the concept hits 60 mph in 5.2 seconds and tops out at 155 mph - while returning a provisional fuel efficiency of 123 miles per gallon equivalent.
