40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Audi A8 super high-tech headlight teased, whole car coming Aug 21

We have to wait one more week before we get to see the 2015 Audi A8 and S8, but it doesn't look like Audi is going to stay quiet until then. After releasing a pair of teaser videos over the last week, it has now released a first detailed picture of the new A8 revealing the trick Matrix LED headlight.
Between the high-beam and low-beam lights, the headlights contain 43 LEDs (not including those for the DRL/turn signal), but the innovative part of Matrix LED system is that a camera can control the high-beam lights - by either dimming them or shutting them off - when other vehicles are detected on the road to prevent the lights from distracting other drivers. Of course the big question remaining is if Audi can get these new headlights to pass the National Highway Traffic Safety Administration and its Federal Motor Vehicle Safety Standards. The taillights also get a cool design with 24 LEDs that use a sequential turn signal
As for the debut of the A8 and S8, we already knew the sedans would be unveiled on August 21 ahead of the Frankfurt Motor Show, but Audi finally made it officially official in a press release, which is posted below. Also be sure to check out the pair of teaser videos Audi has released for these cars recently.

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.
