Though its first official public debut isn't scheduled until early next week, the 2011 Chevy Volt has been introduced to the internet early courtesy of the The Car Connection, which published these apparently official pictures of the revolutionary series hybrid today. In the past few weeks we've seen official teasers shots of the car mixed with spy video taken on the set of Transformers 2: Revenge of the Fallen, all of which have only served to increase excitement ahead of the car's official debut next week. These pics give up the goods like no others, however, and show various GM execs and engineers directly responsible for its development posing alongside like proud papas. The list includes, in order, Tony Posawatz, Bob Lutz, Bob Boniface, Frank Weber, and Andrew Farah.

What we see is a vehicle about the size of the current Chevy Cobalt or next-gen Cruze with a very aerodynamic front end and high rear decklid. There are some futuristic design elements too, including the LED fog lights, black expanse beneath the windows and Volt badging attached to the sideview mirrors. Perhaps the most poignant pic of all is Lutz himself doing a double-handed lean on the production Volt, as GM's product czar has been the most visible figure during the car's very public development.

EPA mileage estimates can be such fuzzy things when you're dealing with hybrid powertrains. We've seen plenty of contention already about real-world results versus EPA numbers for current hybrids, and Chevrolet's upcoming Volt has GM butting heads with the Feds over how the series hybrid eFlex powertrain should be rated. Because the Volt can cover about 40 miles before it needs to fire its range-extending internal combustion engine, it can breeze through the EPA's test cycle with the engine off for 85 percent of the time. With the engine running so little, the Volt could earn an EPA rating above 100 mpg, but the agency is not comfortable with that and wants to change the test for the Volt.

GM argues that altering the test in the way the EPA proposes -- requiring the Volt finish the test with batteries near full charge -- is unfair and won't reflect reality. Moreover, in everyday commuting, the Volt will be an electric car for its first 40 miles, not ever even firing its engine for drivers with commutes short enough or recharging ability at work. The EPA's motivation is to come up with a meaningful mileage rating for the Volt, which will ace the current test. If the Volt gets a rating that is artificially low because the EPA can't figure out a test that correlates to reality, it could also hurt the Volt's case with consumers looking at the $40,000 price tag next to numbers barely better than what a diesel or parallel hybrid can earn.

Excitement around the production version of the Chevy Volt is reaching a fever pitch. Last week we brought you spy video and images of what appeared to be a production Volt on the set of Transformers 2: Revenge of the Fallen, and while General Motors has since revealed that what we saw was not necessarily the series hybrid's final form (and that it was actually a rebodied, gas-powered Malibu), it nonetheless proved that the Volt's design is nearing the end of its gestation. Today GM revealed to Automotive News that the production Volt will, in fact, be unveiled this month as part of the automaker's 100-year anniversary celebration. The main events for the celebration are Monday, Sept. 15th and Tuesday, Sept. 16th, so we expect the car to be unveiled on one of those two days.

Ford Motor Company celebrated its centennial in 2003 and used the occasion to debut an equally exciting yet very different vehicle: the Ford GT. Fast forward five years and the hottest vehicle on everyone's mind is not a supercar, but a series hybrid. Times have certainly changed.

When the Chevy Volt goes on sale in late 2010, it may be joined shortly thereafter by other GM-branded series hybrids using the eFlex architecture. But after the General's bread-and-butter bow-tie division, which brands make the most sense to get their own Volt? We've already seen a Cadillac with underlying eFlex technology, and GM's luxury arm could charge higher prices to offset the cost of the expensive powertrain. After Cadillac, Saturn might be a good bet considering we've already seen an eFlex-based Saturn-branded FlexStream concept.

Susan Docherty, GM's North American vice president of Buick, Pontiac and GMC, thinks GM's driving excitement team is a natural fit for a Volt-like hybrid. Her reason is that the Pontiac brand can attract a younger crowd that readily accepts new technology and cutting-edge design. We're not so sure. If Pontiac is supposed to build excitement, how does that jive with a heavy battery pack in a car that's engineered to save fuel rather than go fast? Then again, nothing says instant torque quite like an electric vehicle. Dealers who bought into building combined Buick, Pontiac and GMC stores will want at least one vehicle in their showrooms based on the eFlex architecture, though, and Pontiac makes more sense than Buick or GMC.

Autoblog reader Michael C has a knack for seeing things we miss. In 2006, he noticed that an image of Bob Lutz lifting the veil on one corner of the yet-to-be-released 2008 Cadillac CTS could be easily manipulated in Photoshop to reveal the car's entire front end. GM recently gave us a similar peek of the production Chevy Volt on a segment that aired on ABC News, and Michael C has once again used Photoshop to give us a very clear view of the production Volt's front end.

Yesterday, of course, we got our fill of the production Chevy Volt when video of it on the set of Transformers 2: Revenge of the Fallen hit the web and a spy shot of the car's iPod-like interior surfaced. While screen grabs from that video showed us an overall view of the Volt from a distance, this is the first time we have an idea of what the car looks like from point blank range. The front end is ultra slippery, a far cry from the concept's unaerodynamic face, but the general look is similar. We're not too far off from GM's official reveal of the production Volt, which could happen as soon as the Paris Motor Show in October. Check out a higher-res version by clicking the pic above, along with all the images we've collected of the production Chevy Volt so far.

The attention of the hybrid technology universe has been focused firmly on two vehicles: the Chevy Volt and the plug-in Prius. On the surface, these two vehicles are primed to be big-time competitors in the battle for mpg-conscious buyers. Not so, says the king of quote, Maximum Bob Lutz. According to Mr. Lutz, the two vehicles are very technologically different. Toyota also says that a plug-in Prius will be in production in 2009, a full year ahead of the Volt. Lutz hypothesizes that the Prius plug-ins will be available only to select fleets and not in large scale production, and the GM Vice Chairman says that the Volt will be available as part of a large test fleet in late 2009, as well.

We agree that the Volt and Prius are technologically different, but we're pretty sure the two vehicles will be competing for the same buyers. After all, Americans are calling for more fuel efficient vehicles and don't care if one's a plug-in parallel hybrid that runs on nickel-metal hydride batteries and the other is a series hybrid with lithium-ion batteries and a "range extender". They just care about whichever one can go further on a drop of fuel.

Ed sent us the top pic pilfered from the Transformers Live Action Blog and judging by the roofline, headlights and taillights, you're looking at the first picture of the production Chevy Volt. Not proof enough? Click on the image above and look closely at the metal plate in front of the sideview mirror. It's emblazoned with the four letters that spell out GM's savior. The Volt it is. Our boys at AutoblogGreen have already called upon the General's minions for a comment, but no response has been delivered to our inbox... yet.

The Chevy Volt is unique in that its engine is really just a generator that produces electricity for the batteries, which then power an electric motor that turns the front wheels for propulsion. While the Volt powertrain is pretty spectacular, it may not be unique for long. British car site AutoCar is reporting that Mazda is not only interested in a similar setup for a future plug-in hybrid, but it already has a working prototype on the road. Mazda engineers told AutoCar that a battery pack charged by a rotary engine is already being used in a Mazda5 mule, and that management is encouraged by the early results but wants to see battery costs go down before proceeding.

If Mazda is working on a series hybrid like the Chevy Volt, that means its owner, Ford, would have direct access to the same technology. We do, however, find it odd that Mazda would use a rotary engine in this setup. While the Wankel engine is very compact and light, it's not very efficient and sucks oil, at least in the RX-8.

General Motors continues to eek out teaser shots of the production Chevy Volt, but it appears that an image of the production interior has slipped through the Empire's net of control. All we have to go on for this image posted on the Motive.com forums is the image itself, which is part of a display panel at what appears to be a sneak preview of the vehicle for god knows who. What we see is a sleek, all-white center console with virtually no buttons. The controls appear to be touch sensitive instead, leaving the face of the console as smooth as a Frigidaire. Good luck installing an aftermarket stereo in this one. Completely flush air vents flank the console, which stands out in contrast to the black dash panel. On top of it all sits the information display, seen here showing the relationship between the "range extending" engine and lithium-ion batteries. What say you? We all know the production Volt isn't going to be as wild as the concept, but does this innovative center console meet your expectations? Also keep in mind that this might not be the real deal, but it seems to be from all appearances.

With enormous V8 land-yachts and even bigger Escalades rolling down America's boulevards, Cadillac doesn't have the most environmentally friendly of images. But that's a perception that the premium GM division is working hard to combat. After unveiling the Escalade two-mode hybrid, reports have begun to surface that Cadillac is considering a four-cylinder model for the American market like the Saab-based BLS it offers in Europe.

New emerging reports now suggest that Cadillac might get its own version of the highly-anticipated Volt plug-in hybrid from its sister-company Chevrolet. No telling at this point if the Cadillac version would be based on the Volt, transplant the Volt's powertrain into an existing Cadillac model, or breed an entirely new Caddy – or for that matter if there's any substance to the rumors – but sources suggest a higher sticker price than the Volt's anticipated $40k.
