700 horsepower Porsche GT2 RS is the wildest 911 ever

The Porsche 911 comes in a variety of flavors, each filling a certain taste for a certain customer. Sitting atop the range is the new 911 GT2 RS. In previous generations, the GT2 had a bit of a reputation as a widowmaker, a 911 with massive power that could snap and bite with the slightest agitation. Porsche says the new model has been civilized, but with 700 horsepower going to the rear wheels, we're sure it's going to be as mad as ever. Power comes from a highly massaged version of the 3.8-liter flat-six from the 911 Turbo S. The rear-mounted engine makes an outrageous 700 horsepower and 553 lb-ft of torque. Like we previously reported, the new car will use water injection to help keep things cool. The only transmission is Porsche's PDK. While enthusiasts may lament the loss of the manual, the RS models have always been about performance above all else. Simply put, the PDK is the better performance option. All that power translates to a 0-60 mph time of 2.7 seconds and a top speed of 211 mph. The engine makes 80 more horsepower than the previous model. That makes it the most powerful road-going 911 ever built. In fact, the 887 horsepower 918 Spyder is the only road-going Porsche that makes more power. The fact that Porsche trusts all of that power to go to the rear is both thrilling and terrifying at the same time. In order to manage traction, the GT2 RS gets a number of upgrades. Rear-wheel steering has become commonplace in the 911 lineup, so it's no surprise to see it here. Sticky tires with 265/35 ZR 20 section rubber at the front and 325/30 ZR 21 section rubber at the rear keep things planted. That comically large rear wing adds downforce, adding to stability. The car gets standard carbon ceramic brakes. While some people prefer traditional rotors for the street, like the PDK, this is all about performance. A number of intakes and outlets complement the rear wing and maximize aerodynamic efficiency. It's a bit of a surprise that with all the focus on downforce, the GT2 RS still manages to top out at 211 mph. The hood, front wings, wheel housing vents, door mirrors, side air intakes, parts of the rear end, and a number of interior components are all made from carbon fiber. The roof has been made of magnesium. If you want to drop any pretense of civility and comfort in the pursuit of speed, Porsche is offering a Weissach package that shaves off another 40 pounds from the already impressive wet weight of 3,241.

Vitruvian Energy crowdfunding to make EEB, a trashy biofuel

When sewage is treated at a wastewater treatment facility, biosolids are the byproduct. After being separated from the water, biosolids are usually sent to a landfill or incinerated. That doesn't mean that they're without value, however. Vitruvian Energy has created a process to make a usable fuel out of this human waste product, and while the source is pretty gross, it is undeniably abundant, and the results are much cleaner. EEB can be made for less than $4 a gallon. In a process that Vitruvian Energy claims is energy efficient, biosolids are femented and introduced to a type of bacteria to create PHA plastic. Reacting the PHA with ethanol creates the ethyl-3-ethoxybutyrate (EEB) biofuel. Vitruvian says EEB can be blended up to 20 percent with gasoline or diesel without any engine modifications. This lowers the carbon footprint of the fuel it's blended into, and serves to oxygenate diesel, leading to fewer harmful emissions. EEB can also be made using other organic waste products, such as corn stover, rice straw and distillers grains. EEB can be made for less than $4 a gallon and isn't subject to the maddening market fluctuations and international politics of fossil fuels. Furthermore, EEB's carbon footprint is 70 percent less than that of fossil fuels. Vitruvian also sees potential for EEB to be used on its own to power vehicles or burned to produce electricity for the grid. So far, Vitruvian Energy has used grants from the California Energy Commission and National Science Foundation to develop EEB, and has tested the fuel in a Pontiac Solstice at Oak Ridge National Laboratory. Now, Vitruvian is wants to test EEB on a larger scale in the real world in order to prove EEB's viability to interested parties in the wastewater treatment industry. In an Indiegogo crowdfunding campaign, Vitruvian Energy hopes to raise $200,000 to build a prototype EEB production line and to run a test vehicle for a year on an EEB-diesel blend on the streets of Seattle. Donors can score some interesting perks such as shirts and bumper stickers that say "Get Clean with Poopaline." Learn more about EEB in the video and press release below.

This Hoonigan mechanic's twin-turbo Trans Am is wonderful

What do you drive when you work on rally machines for a living? Probably a Subaru WRX, and that's what Gregg Hamilton had for a while until working on his car felt too much like his day job. So when he moved from New Zealand to the US to work for Ken Block (with a few stops along the way) he bought something entirely different. This is Gregg's 1979 Pontiac Firebird Trans Am. It's a throwback to another time, but it's anything but stock. It has that magic combination of a big V8 with a manual transmission and rear drive, just like the tin-top racers Gregg watched in his Kiwi youth. He bought it sight unseen from its previous owner in Alabama, and has been tinkering with it ever since. There's something about the flared wheel arches and the classic Firebird gold-striped black livery that has us smitten. Scope out the six-minute clip above from Petrolicious and see if you don't fall for Gregg's Pontiac as well.
