Porsche still deciding on one or two new 911 plug-in hybrids

Back in March, Porsche CEO Oliver Blume told Autocar that the coming Porsche 911 plug-in hybrid "will be the most powerful 911 we've ever had." That quote portended a 992-series 911 with 700 horsepower or more. A new report in Auto Express, however, suggests Porsche is having energetic debates about just what the 911's hybrid strategy will be, and that the only agreed-upon plug-in hybrid 911 so far is a milder version to sit in the middle of the range. Putting all our rumors in a row, in January, Automobile reported on an electrically-assisted 911 with 485 hp and 561 pound-feet of torque. The new AE piece effectively endorses that, saying the mid-range hybrid would follow the program established by the all-wheel drive Cayenne e-Hybrid that produces a combined 455 hp and 516 lb-ft. The 911 would naturally use a flat-six instead of the Cayenne's 3.0-liter V6, and the sports car would be tuned for better sound response and sharper reflexes. AE says fuel economy for this hybrid should be at least 80 eMPG, with emissions of less than 80 grams per kilometer. The current base Carrera is currently rated at a maximum 38.2 mpg in the UK, with minimum emissions of 169 g/km. The hybrid, fitted with a double-clutch gearbox and Porsche's mechanical all-wheel-drive system, could run from a stop to 62 miles per hour in less than four seconds, making it more efficient than a base Carrera and much faster than a Carrera 4S. AE says there remains only "the potential for Porsche to add a second, more powerful hybrid 911," and says its sources claim that's what's "causing the most consternation behind closed doors." This one would be the twin-turbocharged, 700-hp beastie that, as a series production car, would have a hard time not usurping the 540-hp Turbo, 580-hp Turbo S, and 607-hp Turbo S Exclusive. True, the hybrid would be handicapped with a 550-pound battery pack, but the instant acceleration and handling benefits of electric AWD — with no connection between the axles — could provide the final edge over the other three. As such, it makes sense that there'd be a whole lot of debate about a flagship 911 hybrid. On the other hand, such a monster seems like an eventuality in view of Porsche's electrified aspirations, the lessons gained from the 918 Hybrid and the 919 Hybrid Le Mans racer, and the fact that CEO Blume has already spoken. The Stuttgart carmaker expects a sales mix of 25 percent electric, 25 percent hybrid, and 50 percent conventional powertrains by 2025.

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.

GM reintroduces Tripower name in the worst way possible

The story of General Motors' use of the Tripower moniker begins way back in 1957, when Semon E. "Bunkie" Knudsen, then General Manager of GM's Pontiac division, directed his engineers to inject more performance into his brand's line of V8-powered automobiles. Fuel injection was an option, but hot rodders flocked instead to Tri-Power (marketed way back when with a hyphen), which grafted a trio of two-barrel Rochester carburetors onto a single intake manifold. A legend was born. And that legend was born of performance. At idle and when full power wasn't required, Pontiac's Tri-Power system used just the middle carburetor, which helped make the setup easier to tune. Depending on the year and model, either a vacuum system or a mechanical linkage opened up the two outer carbs, thereby switching from two barrels to six, and allowing the engine to take in more fuel and air. And it was an easy marketing win – six barrels is better than four barrels, right? Because performance! So, when news filtered in that GM has resurrected the Tripower name, those of us who grew up attending classic car shows and wrenching on old Pontiacs did a double-take. And then we all collectively sighed. Turns out that today's Tripower refers to a trio of fuel-saving measures that include cylinder deactivation, active thermal management, and intake valve lift control, according to Automotive News. And, at least for now, it applies to GM's line of fullsize trucks powered by a 2.7-liter turbocharged four-cylinder engine. We're all for saving fuel whenever possible. And we have zero say in how any automaker chooses to market its products and technologies. But, we'll offer our two cents anyway: Relaunching a storied name from the past is fine. Relaunching a storied name from the past while completely overlooking the reasons the name got famous in the first place is only going to irritate the people who remember the name in the first place. Couldn't they just call this new technology package something else?
