One of the most persistent questions around the Chevrolet Volt - aside from whether or not GM will be around long enough to build it - is the fuel economy rating. The problem arises from the unique combination of plug-in electric drive and internal combustion range extender. The current standard test cycles used by the EPA for purposes of calculating the mileage of internal combustion cars are only 11 miles long for the urban cycle and 10.3 miles for the highway. Both of those distances are well within the 40 mile battery range of the Volt. If the current test procedure was used the car would use no gas and this is clearly not a realistic evaluation.

According to the New York Times, the current plan is to run car through each of the test cycles until the battery reaches the “depletion” point. From this data an equivalent mpg figure will be determined. The Volt will then be run on each cycle in charge sustaining mode to calculate fuel consumption. Researchers from the Argonne National Lab are currently studying real world driving habits to determine a “utility factor″ for blending the two figures. It is expected that this procedure will yield a final sticker value that tops 100 mpg. Of course, because all of these choices are somewhat arbitrary, the bickering will surely continue for the foreseeable future.

Perhaps one of the biggest fans on the planet of the Chevrolet Volt is Dr. Lyle Dennis, a New York city neuro-surgeon. Immediately after originally seeing the Volt concept in January 2007, Dennis launched GM-Volt.com. Ever since then he and his readers have been cheerleaders for GM’s extended-range EV. Dennis set up a waiting list for people to register their interest in the car, and over 45,000 people have signed up. With the financial crisis that’s engulfing General Motors right now, the Volt has remained the only upcoming product that hasn’t seen its development dollars cut yet. However, even though the engineering teams are still working on the Volt, the car is ultimately dependent on the survival of the company as a whole. Lyle Dennis wants to maker sure that GM, and thus the Volt, survive. To that end he has written a letter targeted at President Bush, Congress and Treasury secretary Henry Paulson urging them to provide financial aid to GM as soon as possible. If you’re interested in expressing your support you can print out the letter from the site, sign it and send it to your representatives.

Some of you may have noticed a story posted elsewhere on the interwebs late last evening about the Chevy Volt. As the story goes, a friend of a friend of a friend, etc told the writer that the Volt program was being put on indefinite hold due to the company’s money troubles. With GM releasing its third quarter results in a couple of hours and a huge loss expected, virtually every program at GM is being cut back or delayed. The one exception to that (so far at least) remains the Volt. We checked with the primary spokesman for the Volt program at GM Rob Peterson first thing this morning on this rumor. Peterson tells us that “there’s no truth in that statement whatsoever.” So the Volt remains on track but GM is expected to announce some other big cuts this morning including lay offs among engineering staff (not related to the E-Flex program).

According to a Reuters report, General Motors has chosen Troy, MI-based Compact Power Inc. as the supplier of battery packs for the initial production run of Chevrolet Volts. Compact Power is a subsidiary of South Korean conglomerate LG Chem and was one of two groups that were awarded development contracts for the Volt in June 2007. The other contract went to a partnership of Continental and A123 Systems. CPI has been rumored to have won the production contract for some time and GM acknowledged in late summer that a decision had been made. An official announcement is not expected until some time in November, perhaps at the Los Angeles Auto Show. While a technical decision has been made, GM and CPI still have to settle the commercial details including how the carmaker and supplier will split warranty costs. CPI has been considered to be in the lead since very early on when they delivered their first prototype battery packs almost two months before Continental/A123. When we spoke to Bob Lutz back in June he said although one supplier was in the lead, both companies were continuing to work on packs in the hope of accelerating the learning process.

Here in the U.S. market, the name Electra was used on big Buick sedans for more than four decades but it hasn’t appeared in a new car showroom since 1990. It looks like the Electra could be be making a comeback soon, but not in America. It turns out that Vauxhall, the brand that GM uses to sell right-hand drive Opels in the UK, filed a trademark application back in June for the Vauxhall Electra. GM officials have acknowledged previously that both the Chevy Volt and an Opel badged E-Flex vehicle would be offered in Europe. The Opel/Vauxhall vehicle will likely be based on the Flextreme concept that was shown at last year’s Frankfurt Motor Show. The Electra (if that’s what it’s called) will likely debut sometime in 2011. Saturn is also expected to get a version of the Flextreme here in the U.S., and it will be interesting to see if it revives the Electra name here.

After reaching an agreement with the California Air Resources Board recently that would essentially see the Chevy Volt classed as an electric car, it appears GM has now also worked things out with the EPA. The automaker and the environmental protection agency have been discussing just how extended range EVs like the Volt should be tested to evaluate fuel consumption and emissions. The federal agency responsible for enforcing the emissions and fuel economy standards had wanted to treat the Volt like a hybrid so that the battery would be charged at the end of the test cycle.

Although a new testing methodology has not been finalized, GM and the EPA have reportedly reached a preliminary agreement on new procedures that would see the Volt get a rating of at least 100 mpg. The new procedures would be applied to all plug-in vehicles and would rely more heavily on the electric drive capabilities than the internal combustion engine.

Update: GM Spokesman Rob Peterson has just let us know that the Seattle Times report is based on an earlier erroneous, Bloomberg report. GM is still talking to the EPA and nothing has changed in the last two weeks.

By now many of us around these parts know who Shai Agassi is and what he wants to do. He wants to build a distribution infrastructure of swappable batteries to be used in electric cars with the ultimate goal of making EVs mainstream. The problem is that electric cars remain an expensive proposition. Even with Agassi’s approach that would sell the EV without a battery and add on a subscription model for the battery, the up-front cost will remain higher than conventional cars. Nonetheless, in Paris last week Agassi was telling the Wall Street Journal that he doesn’t think the Chevy Volt would ever be more than a niche product. He bases that on price of the car, expected to be around $40,000 before any tax incentives.

Agassi thinks that is too high for what would otherwise be a $20,000 vehicle, like the Chevy Cruze on which it’s based. As far as he goes, he’s right, but he doesn’t go far enough. GM and everyone else know that any car that will be mainstream has to have an affordable up-front cost. That’s why GM originally wanted a $30,000 price point for the Volt. That’s why they went with a smaller battery and range extender. The realities of the battery situation will continue to make longer range electric driving unaffordable for the foreseeable future from a purchase standpoint regardless of whether you take the GM or Better Place approach.

While Agassi’s subscription-based software background may make sense for large deep pocketed corporations, for regular people the cost of entry is a much bigger hurdle than the total cost of ownership. If you can’t pay the door charge, it doesn’t matter if the drinks are free once you get inside. That’s why so many people relied on cheap lease deals and nothing down mortgages over the last decade. The current reality of what is happening in the financial markets means that there is a high probability that none of these approaches will prove to be viable anytime soon. Unless a manufacturer can find a way to get that entry cost down and soon, all EVs will likely remain niche products for many more years.

There has been a fair bit of discussion and controversy in the last couple of weeks on the interwebs about the exact nature of the powerflow and battery charging in the Chevy Volt. Back in July GM’s Larry Nitz discussed how the charge sustaining mode would work. As with parallel hybrids the battery is generally kept between about 35 and 85 percent charge. That means when the battery reaches its “depletion” point it still has a significant amount of charge left. The range extender has less power output than the the electric drive motor is capable of (100 hp vs 150 hp) but it has enough output to work in most day-to-day driving conditions. The range extender doesn’t normally try to charge the battery fully as that is deemed to be less efficient and more costly than holding the battery at the minimum until the car can be plugged in. For the times when more power is needed such as acceleration or hill climbing some of the reserve battery power is available to be used. The battery can be drawn down below the “depletion” point to about 25-30 percent. When this happens, a combination of regenerative braking and some surplus power from the range extender will bring the battery back up to the minimum. A video after the jump shows the various modes and the power flow.

Ever since the Chevrolet Volt appeared as a concept last year, debate has been hot and heavy over exactly what it is. Although many call it a hybrid because it has a battery and an engine, GM prefers to call it an extended range-electric vehicle (ER-EV). That poses a problem for GM when it comes to emissions and fuel economy testing. With its 40 mile electric only range the Volt could complete the US06 test cycle that is part of the current EPA test regimen without ever running its engine. So far this doesn’t sit well with the EPA which considers the Volt a hybrid and expects it to complete the test cycle with a charged battery. GM and the feds have been going back and forth on this for months. Reports out this morning on Bloomberg and the Detroit Free Press indicated that GM and the EPA had reached an agreement that would potentially see the Volt as the first car classified with a 100 mpg rating are erroneous. We called spokesman Rob Peterson to get the scoop, and it turns out that GM has reached an agreement with the California Air Resources Board, (CARB) on a unique classification for the Volt. Peterson told ABG that this classification would reflect the Volt’s true capability, essentially treating it as an EV. According to Peterson, “the classification helps us to optimize the Volt for what it does do, instead of being put into the category with a normal hybrid.” This will potentially allow GM to run the Volt with the planned charge sustaining mode rather than having to run the engine to fully recharge the battery at the end of the test.

The agreement with CARB gives GM a bargaining chip in its talks with the EPA, but Peterson cautions that the automaker and the federal agency “still have a long way to go” to finalize any agreement. The Volt may yet get that magic 100 mpg rating, but it’s not there yet.

General Motors made its case to a Detroit City Council committee on Wednesday in a bid to get some property tax brakes for its Hamtramck assembly plant. The Poletown plant is where General Motor is planning to build the Chevrolet Volt beginning in late 2010 and GM told the council that the new production vehicles there would add 550 jobs to the facility. In return for creating those jobs in the city, GM is seeking $136 million in property tax relief on the improvements over the next 25 years. The plant already employs 1,944 people who build the Buick Lucerne and Cadillac DTS. GM is planning on spending $336 million on the plant over the next two years in order to swtich over to the new, smaller ER-EV Volt. The full council is expected to vote to approve the abatements by sometime next week.

Now that you′ve had time to digest the look of the production Chevrolet Volt in a somewhat more flattering environment, it’s time to have your say. Obviously it changed a lot, but that was a necessity to get this first one out the door and meet the performance targets. The wheels shrunk, the greenhouse grew, and the transparent shoulders are now opaque. But this is now a real and buildable car. You′ve all been having your say in the comments, now let’s get some numbers from a thoroughly unscientific, self-selecting poll. Did Bob Boniface and his team break it or fix it?

A week after some admittedly bad photos of the production Chevrolet Volt were accidently released on the GM media website, the car itself was officially unveiled this morning as part of GM’s centennial celebration in Detroit. Fortunately, the vehicle we saw this morning looked vastly better than the car in the photos we saw last week. Unlike the unapproved shots that made the car look tall, wide and bloated, what we saw today was a far sleeker machine. Aside from some details such as the mirrors, the car actually looks much like the car we saw in the spy photos from the Transformers 2 film shoot.

That means it looks less like a Prius than we thought based on the leaked shots. As we’ve known for months, the production car had to change in order to optimize the aerodynamics. This had to be done to limit parasitic losses and maximize the car’s ability to recapture kinetic energy. The back end is the most obvious carryover from the concept while the front gets the smoother, more rounded look we’ve been seeing in teaser shots for months. There’s more after the jump.
