One of the makers that we encountered setting up of theMaker Faire Detroiton Friday afternoon was Douglas Amick. Amick was unloading the A2, a three-wheeled, battery-powered, wind-assisted tandem-two-seater. The A2 was originally built by Amick's late father James. The elder Amick devised the aerodynamic arch on the rear of the vehicle which is claimed to help propel the vehicle forward in cross-winds. Apparently, airflow coming in at an angle to the vehicle will swirl around as it passes through the arch actually applying force to the rear of the vehicle giving it some boost. We'll have to check with some contacts with aerodynamic expertise on the veracity of this claim, but the vehicle is kind of cool looking. Apparently, it originally had aluminum air batteries installed but they are no longer functional.

Porsche confirms 2011 launch of Panamera S Hybrid— Autoblog Green

Buried withinPorsche'srecent announcement regarding itsplans to test three electric Boxsters, the company openly confirmed that the launch of the Panamera S Hybrid is on track for 2011. Though perhaps not as innovative or as those racy electric vehicles, the Panamera S Hybrid still hails from Stuttgart and, therefore, is bound to be one exhilarating ride.
The upcoming Panamera will borrow the hybrid hardware found in the currentCayenne S Hybrid. That means it will sport a 329-horsepower 3.0-liter V6 engine mated to a 46 hp electric motor. Like the Cayenne S Hybrid, the Panamera's parallel hybrid setupboasts the ability to operate at low speeds under electric power alone. When the production Panamera S Hybrid takes to the streets in 2011, it will become the company's second model to sport a hybrid powertrain, a remarkable achievement considering that few people associate Porsche with fuel efficiency. Follow the jump for more info on Porsche's fuel-saving plans.

PRESS RELEASE
Porsche Develops Research Cars with Electric Drive
Stuttgart. Electric drive will take on an increasingly important role in the further enhancement of Porsche Intelligent Performance. To combine greater efficiency with even lower fuel consumption and emissions, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is working consistently not only on the ongoing development of hybrid concepts already in regular production, but also on practical tests as part of the Stuttgart Model Region for Electromobility, using three research cars with all-electric drive based on the Porsche Boxster.
In the test process, these three electric Boxsters are to provide an initial first important insight into new electric drive components and battery systems for all-electric vehicle drive. This field test intended to also provide further findings on the infrastructure required for electromobility, user behaviour and the demands made of future products, is to start in early 2011.
Michael Macht, the President and Chief Executive Officer of Porsche AG, sees this contribution made by Porsche as absolutely essential:"We will definitely be offering an electric sports car in future. But such a concept only makes sense if it offers product qualities typical of a Porsche."
Porsche has been committed to electric mobility for a long time, thus helping to preserve the environment and save resources in our world: The spectacular concept study of the 918 Spyder high-performance mid-engined sports car with plug-in hybrid combines high-tech breakthroughs in engine technology and electromobility with a truly fascinating range of further qualities. Emissions otherwise to be found only on a super-mini of just 70 g/km CO2 with three litres fuel consumption for 100 kilometres in the NEDC (equal to 94.1 mpg imp), come with the performance of a super sportscar developing well over 600 horsepower.
The hybrid system of the 911 GT3 R Hybrid has been developed especially for racing, with two 60 kW (82 hp) electric motors on the front axle boosting the 480 hp six-cylinder power unit fitted at the rear. Replacing conventional batteries there is an electrical flywheel power storage system re-charged whenever the driver applies the brakes and thus delivering energy to the electric motors. The 911 GT3 R Hybrid has already proven its racing qualities in the 24 Hours of Nürburgring.
Introducing the Cayenne S Hybrid, Porsche also offers the first production car in the range able to run under electric power alone. With maximum output of 380 hp, the Cayenne S Hybrid makes do in the NEDC cycle with just 8.2 ltr/100 km (equal to 34.5 mpg imp), and CO2 emissions reduced to a mere 193 g/km. This hybrid technology will also be featured in the future Panamera S Hybrid due to enter the market next year.

Plug-In 2010: Bill Nye, Chelsea Sexton return for public night panel— Autoblog Green

Bill Nye,"The Science Guy,"Jessie Deeter, the producer ofWho Killed The Electric Car?andRevenge of the Electric Car, and our ownChelsea Sextontook to the stage at the close of public night at thePlug-in 2010 Conference. With this line-up, it was more than 66 percentthe same as last year, when Nye, Sexton and Electric Car director Chris Paine answered audience questions. Given the"preaching to the choir,"audience-led nature of the event, we thought there would probably be a lot of readers who would want to"attend,"digitally, so we're posting an audio recording of the entire two-hour eventafter the jump. What does it contain?
How about a short preview (verbal, not video) of Revenge of the Electric Car? Deeter said that the film will focus on three main stories:General Motorsand theChevrolet Volt,Tesla Motors,Nissanand theLeafand electric car mechanic Gadget. How about the panelists' predictions of the percentage of new cars that are plug-ins by 2020? Nye said he doesn't think it'll be 10 percent, Sexton said it'll totally be determined by how many the OEMs are willing to build. How about lots of disparaging comments about adding sound to silent electric cars? How about Nye calling lithium supply worries the"reddest of herrings"? How about one member of the audience proudly saying he's been driving an EV1 since 1998, and Nye replying,"You must be exhausted"? Zing! All these classics and more await youafter the jump.

First Drive: 2011 Nissan Leaf doesn't change the game, just the players— Autoblog Green
We've met theNissan Leafbefore. Firstat its coming-out party in Japan, followed by an all-too-brief stint behind the wheel of aVersa-based prototypelate last year. Now we've had a chance to sample Nissan's first foray into the world of electric vehicles in production form and the automaker picked one of its most important markets– the heart of Silicon Valley– to give us some seat time.
If there's any area ripe for early-EV adoption, it's San Jose, CA. And during a quick test loop through the tight confines of Santana Row and a run through the city's suburban surrounds, it's obvious that the first mass-produced EV is officially ready for prime-time.

If you're anything like the 16,300 people who have reserved a Leaf for lease ahead of its December launch, you've already devoured all the salient details in the run-up to its release. For those of you late to the party, here's the quick and dirty version of what you get for your $32,780– or just over $25,000 after you factor in applicable federal incentives (in some states, like California, you can lop off another $5,000).
The Leaf is a five-door, five-passenger city car fitted with a 24kW lithium-ion battery pack complete with 48 separate modules housing four cells a piece. We're pointing out the number of cells because if one fails, Nissan can replace the individual modules without having to replace the entire battery pack– further proof that the Japanese automaker is keenly aware of the issues that could plague a mass-market EV.



All those crazed electronics get routed to the front wheels through a front-mounted motor producing 107 horsepower and 208 pound-feet of torque. Top speed comes in at just under 90 mph and Nissan claims a 0-60 mph time under ten seconds. Neither figure matters much in this particular slice of the auto world, but both numbers suggest this isn't yet another four-wheeled electric toy.
What arguably matters most is range, and with the Leaf, Nissan contends the slippery hatch (.29 cD) is good for 100 miles per charge– a reasonable amount for its target demographic of urban dwellers and inner-city commuters. When the juice does run out, you can plug one of three different cables into one of two front-mounted ports: 110-, 220- or 440-volt.
The first option is available to anyone who can plug in a toaster, but it provides barely enough juice to top up the batteries after 20 hours of charge time and it doesn't do bagels.

The two other options are far more advantageous. An electrician can adapt your existing 220-volt clothes dryer outlet, thus reducing charge time to around seven hours total. The cost of the in-house charger runs around $2,200, but the Feds will take care of half that amount and Nissan will not only arrange for the installation, it'll allow you to roll the cost of the setup into your monthly payments. If you're lucky enough to live around one of the 440-volt"Quick Charge"stations, you can get up to 80 percent of the battery's capacity in around 30 minutes. Expect to see these popping up all over the U.S.– from California to New York– in the coming months and years... assuming all goes according to plan.
On the subject of cost, the aforementioned $32,780 sticker is the base price (again, not including any government rebates), but if you want the backup camera and spoiler-mounted solar panel, you can option up for the SL model at a $940 premium. The rearview camera is a reasonable accessory, much more so than the solar panel, which simply trickle charges a 12-volt battery to supply electrons to the headlights, clock and a few low-power accessories. Nissan officials admit it's more of a marketing ploy than a functional addition, but that hasn't stopped 85 percent of pre-order customers from optioning up for the SL trim. And for just under a grand to burnish your soon-to-be unassailable green halo, why not?


So, with the facts and figures out of the way, what's it like? To begin with, bigger than we expected.
On our initial approach, we thought the Leaf was sitting on a podium. Once we got a clear view, it was obvious that not only is the greenhouse expansive, but it's on the large side of the B-segment. The footprint is like any other subcompact, but the beltline rises high and there's copious quantities of glass expanding from the windshield back.
Although aerodynamic efficiency is a top priority, it's not immediately obvious that the Leaf is anything other than a standard around-town runabout. The only tell-tales are the panel up front that hides the two charging ports and the rather rotund rump that protrudes several inches past the rear wheels in a rather Gallic fashion (fitting, considering Nissan's Renault ties). The taillamps are thin and long, running from below the functional spoiler to halfway down the hatch, and a quartet of diffusers at the rear tip you off to the smooth underbody tray beneath.




The headlights are more compelling, bulging out from the fenders more than some concepts displayed on the auto show circuit every year. Predictably, they serve a functional purpose. When Nissan was testing the Leaf, they noticed a fair amount of wind noise coming off the side mirrors. And with any EV, exterior noise is amplified due to the lack of racket emanating from under-hood. So the lights were redesigned to split the air leading towards the mirrors, eliminating buffeting and drawing a clear line through the atmosphere.
However, noise had to be added back in. To assuage the fears of the sight-impaired, Nissan fitted a small speaker to the left-front side of the Leaf that emits a subtle tone up to 18 mph. After that, Nissan believes wind and tire noise will be enough to warn pedestrians of an approaching Leaf. And no, customized sounds aren't in the cards, but when you shift the drive selector into Reverse, it does emit a faint, commercial truck-like beep.


Our first stint inside was in the back seat, and after throwing our camera bag and coat into the commodious trunk (despite the fact that 900 pounds worth of batteries are mounted behind and under the rear seats), we were pleasantly surprised by the amount of space in back. Nissan claims you can fit three people in the rear, but as always, make sure the person in the middle is suitably malnourished and amiable.
Situated behind the driver, the ride was suitably smooth thanks to an independent suspension up front and a torsion beam in the rear, while 16-inch wheels wrapped in low-rolling resistance tires soaked up what little bumps were found in and around the city.
The materials inside are a few degrees better than what you'd find in an economy car of similar size, with cloth seating as the only material (dead cow wouldn't be P.C.) and a combination of plastics that ran the gamut from mildly plush to the high side of acceptable.


From behind the wheel, the seating position is surprisingly elevated, necessary to see over the acres of dash in front of you. A two-tiered instrument cluster is front-and-center, with a digital speedometer up top, flanked by a clock, exterior temperature gauge and an LCD"tree"to let you know if you're being a good boy with the electric throttle.
The second display, nestled in the traditional space behind the steering wheel, provides more information, including temperature and range, a power indicator and the normal assortment of trip and transmission information. It's relatively straight-forward, as is the navigation screen at the center of the dash that can display a myriad of power, charge and travel information. Taken as a whole, it's technofabulous, but the learning curve doesn't seem out of reach of your average iPhone user.
To get things underway, you press a small, glowing button to the right of the steering wheel, release the electronic parking brake, then move the silver, 'hockey puck' drive selector to the left and then down to select Drive. Release the brake, press the accelerator and you're whisked forward to the sound of... nothing.
As we experienced in theTesla Roadster, this initial lack of noise is slightly unnerving at first, but as speeds increase, the sound of wind and the low rumbling of the tires take over. The steering is commuter-friendly light, slightly overboosted, but perfect for running around town.
Give the throttle a determined shove and the Leaf gets moving with authority. It's not blazing, certainly but it's adequately quick, with plenty of punch to motivate the Leaf's portly 3,700-pound curb weight. In Normal mode, throttle resistance is minimal, but switching to Eco stiffens things up to promote lighter inputs. However, if you take it to the floor, the Leaf responds with the same amount of thrust you'd get in the standard mode.

On the other hand, braking was slightly less endearing, with a wooden feel accentuated by the minimal amount of travel before things get biting. With the system set back to Normal, the regenerative brakes provide a subtle amount of"engine braking,"but in Eco it becomes more pronounced, slowing the Leaf down quicker and giving the batteries a minimal jolt of energy. We were expecting something akin to what we enjoyed in the Tesla– the regenerative braking remained one of our favorite driving features– but it's decidedly less aggressive in the Leaf. And considering the application, it should be.
If there's any overarching sense from behind the wheel, it's that the Leaf is simply a car. The gadgetry is impressive, but no more so than some of the hybrid options available from Nissan's competitors. The interior is comfortable and spacious, with more than enough room for four people and their assorted trappings. Few things stand out, and that's exactly its point. Nissan isn't out to change the driving experience, it's just changing the method of motivation. And more than anything else, that's what's going to bring electric vehicles into the mainstream.
