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.

For some of us that day can't come soon enough, and in honor of Earth Day we've put together a list of our favorite car giveaways so you can save some green while being green.  Win a 2021 Porsche Taycan Turbo S and $20,000 - Enter Here If there’s one thing Porsche is good at, itÂ’s making fast, beautiful cars, and the Taycan Turbo S is no exception. Making 750 horsepower, 774 lb-ft of torque and a top speed of 161 miles per hour, punching the accelerator will surely throw you back in your seat. In fact, its 0-60 time of 2.6 seconds matches that of the quickest Porsche 911 ever made, the Turbo S. The difference between this Taycan Turbo S and that 911 Turbo S, of course, is that the only reason youÂ’ll ever need to stop off at a gas station is to fill up on snacks. That and the fact the Taycan doesn't actually have a turbo anywhere in the car. We wouldnÂ’t be reaching for a bag of FlaminÂ’ Hot Cheetos, though, because this incredibly comfortable leather interior is immaculate, and weÂ’d hope to keep it that way. Enter here for a chance to win this prize worth $220,000. Win a Himalaya Land Rover Defender 110 EV and $20,000 - Enter Here The Land Rover Defender is an icon: an intense, luxurious off-roader that turns heads and can crawl up nearly anything. The problem? For the past 20+ years it hasn't been available in the United States and it's never been what youÂ’d call environmentally friendly. But this Defender is different. ItÂ’s vintage, restored by Himalaya and itÂ’s all-electric. At 275 horsepower, you wonÂ’t be thrown back in your seat, but the 406 lb-ft of torque helps make this an incredibly capable rock crawler.

The 2017 Acura NSX will cost $156,000

Back in October, when our Editor-in-Chief Mike Austin drove the 2017 Acura NSX for the first time in the Bay Area and at Sonoma Raceway, we guessed that the hybrid supercar would start at around the $170,000 price point. We weren't that far off – it starts at $156,000, and tops out around $205,000. But now that we have a solid sense of what Acura thinks this car is worth, and we know what they benchmarked the NSX against, we can compare apples to apples. Let's be clear: we like this car. Austin described it as "makes you giggle" fast, everyday-comfortable, and chock full of impressive party tricks like seamless shifting – with only a few foibles, like numb steering, to spoil the illusion of perfection. Back to the benchmarked cars. Acura says the NSX will compete with the Audi R8, and was developed to compete with the now-superseded 458 Italia. Let's start with the 2017 R8 V10 Plus – pricing hasn't been released, and a direct Euro-to-USD conversion isn't the whole story, but it starts at the equivalent of $179,000 in Europe. For that, the R8 V10 Plus provides 610 horsepower, a seven-speed DCT, and a 3.2-second sprint to 60 mph. The 458's successor, the 488 GTB, should be more expensive than the $243,000 the old model started at, and provides 661 hp, a seven-speed dual-clutch, and a 0-60 time of around three seconds (official numbers haven't been released for acceleration). For less money than either of these cars, the NSX delivers ... less. Total system output is 573 hp. It has a slight edge in gear count, at nine speeds, and should beat the R8 to 60 mph. But there's no V10, let alone Ferrari's feral turbocharged V8. It'll be up to buyers to determine if the compromises involved are worth a few thousand dollars in savings, if no options are selected. It should also be noted that Acura describes this as its first "built-to-order" vehicle, but the limited external color options and interior schemes don't appear to be much different than the extent to which you can customize an Accord. The configurator goes live on February 25th, if you want to see for yourself. Lastly, in what now seems to be a necessary part of a new high-end car launch, Acura will auction off VIN 001, the first production NSX, at Barrett-Jackson in January. All proceeds from that auction will benefit two charities: the Pediatric Brain Tumor Foundation and Camp Southern Ground.
