Volkswagen CEO Martin Winterkorn has revealed a new concept today called the Golf Twin Drive. The Twin Drive is a plug-in electric hybrid that uses a powerful 82-hp electric motor and a 2.0L turbodiesel producing 122 hp. The electric motor is fed energy from a pack of lithium-ion batteries that can sustain the car's mobility for about 50 kilometers or 31 miles, after which the diesel engine will take over propulsion duties. While we do know the Twin Drive also features start-stop technology and regenerative brakes, we're still a bit unclear on how everything works. From the way it's been described in the news and VW's somewhat vague press release that we've translated from German, the gas and electric motors are completely isolated, with one unable to provide the other assistance under heavy loads like in the Prius or a typical parallel hybrid. At the same time, the Twin Drive Golf doesn't sound like a series hybrid in the same vein as the Chevy Volt, as the gas engine (or diesel in this case) is directly connected to the drive wheels. In other words, the engine onboard is not simply a range-extending generator supplying power to recharge the batteries like in the Volt. What the Twin Drive appears to be is a plug-in hybrid with a very robust electric drivetrain that's forced to drag around an internal combustion engine in case it gets too far away from home. Regardless, when we find out exactly how Twin Drive works, we'll let you know.
Volkswagen is developing the Twin Drive system with eight German partners and is planning a trial fleet of 20 Golfs outfitted with the system in 2010. The German government is along for the ride, and for a good bit of green PR, VW promises the the electricity used to charge the fleet of test vehicles will be generated from renewable sources like wind and solar power.
Bob Lutz revealed to the Seattle Times that the price point for his company's Chevy Volt series hybrid electric vehicle will be $40,000, or around $10,000 more than originally estimated. Lutz also told the paper that the first-generation of the Volt would generate no profit for General Motors. There's still hope for buyers who were hoping to snag a Volt closer to $30,000, as potential tax incentives on state and federal levels could trim the price substantially. Congress is currently considering proposed legislation for plug-in hybrid tax credits on the order of around $7,000. Still, there's no telling what demand there will be for the Volt, and if it's higher than the supply, we could see markups on GM's high-tech hybrid from dealers who are trying to survive this transition from a market dominated by profitable trucks and SUVs to smaller, fuel-efficient vehicles. According to Lutz, however, cars like the Volt are the way of the future, and GM's car czar expects that between 2020 and 2025 a quarter to a half of all vehicles sold will be either electric- or hydrogen-powered. We'd put our money on electric, as this country has not gotten serious yet about building a distribution network for hydrogen.

In what seems like a convenient answer to Mark Fields' request just yesterday for government assistance for the development of plug-in hybrids, the Department of Energy has just announced that it will be granting up to $30 million for just this type of vehicle. Not that thirty-mill is a small sum or anything, but that amount of money will be spread rather thin, being divided across three separate projects from three different manufacturers. Ford is one of them, while General Motors will receive funding for battery development and Chrysler, in partnership with General Electric, will also get some love.
The end-goal of this funding is a plug-in hybrid vehicle that is capable of traveling 40 miles on electric power alone. The DOE hopes that these specifications can be cost-effective by the year 2014 with vehicles on the road around 2016. We're a little puzzled, however, by the relatively small amount of money being handed out to reach these goals. Hydrogen fuel cell technology has received over four times as much funding and is nowhere near as close to production as PHEVs. Regardless, we look forward to seeing some of these investments bear fruit as soon as possible.
If you read our post yesterday that talked about a lithium Ion-powered plug-in Prius for 2010, thoughts of 100 mpg cars may have danced in your head. Well, take it easy, because the think tank over at Toyota doesn't want you to get your hopes too high. Toyota Advanced Technology manager Bill Reinert spoke in Washington yesterday at a plug-in conference and said that real-world driving conditions will make 100 mpg unattainable for many drivers. While plugging in more powerful batteries will give drivers a full battery and greater EV range, hard acceleration could limit electric-only driving to well under 40 miles.
While it's nice of Toyota to give a plug-in reality check to an efficiency-hungry public, we don't think this message is going to get through to the masses. Besides, if Toyota's next-gen hybrids can reach anything close to 100 mpg, we think shoppers of fuel-efficient vehicles will be too busy foaming at the mouth to even notice.
In these days of nearly nonexistent profits for every one of Detroit's Big Three automakers, R&D funds must be allocated very carefully. In contrast, Japanese manufacturers such as Toyota and Honda have been earning profits on a yearly basis. Not long ago, a mild spat arose regarding whether or not the Japanese government helped fund the development of Toyota's Hybrid Synergy Drive. Even if they didn't do it in the past, Ford's President of the Americas Mark Fields indicated that they are doing it now at a conference held today in Washington, D.C. by Brookings and Google.org titled Plug-In Electric Vehicles 2008: What Role for Washington?
Fields called on the U.S. government to step up to the plate, mentioning tax breaks and incentives as one option to aid consumers who'd like to purchase these ultimately expensive vehicles one day. On the manufacturing side, Fields suggests that plug-in hybrids should be a "national priority", with Washington needing to allocate funds for research and development. Another area singled out is a domestic supply of batteries, since most of the units used in today's hybrids are being manufactured overseas.
It should be noted that General Motors already has a head start towards PHEVs with its upcoming Chevy Volt. As far as we're aware, the development costs for this vehicle and its batteries has been moving forward without direct assistance from the government. Feel free to read Field's entire speech after the break.
The current Prius is baked from a refined recipe that results in a roomy, practical and efficient vehicle lurking under an eco-statement exterior, or at least we thought so. Five years on, it's still the most popular way to conspicuously consume under the guise of saving the planet. Toyota hasn't been resting on the success of its green badge of targeted consumerism, so we're going to see a new Prius at the 2009 North American International Auto Show in January, according to Toyota President Watanabe. The 3rd-generation Prius will grow in size, and engine displacement will be bumped to 1.8 liters to increase performance. Despite the increase in size and sprightliness, weight will reportedly hold steady. Further changes are in store after the launch, with plug-in and Li-Ion updates to come.
The nameplate will also move beyond a single model and become a sub-brand during the reign of Prius the III. More body styles are coming, and if you think the Prius is a roachy-looking thing, the concept hints Toyota has given us are possibly even weirder. The sub-1,000 pound 1/X might offer a glimpse at another type of Prius, though more realistically, the sad-eyed Hybrid X vannish concept suggests the way things are headed without the ridiculous pronunciation of its featherweight companion. If things go according to Toyota's plan for world domination, the Prius will become one of the pillars upon which the marque is built, next to the Corolla and Camry institutions.
As we've heard before, the next generation of AMG-massaged Mercs will have to balance high output with low emissions. That means more turbos, less displacement and (gasp) hybrids.
The big and bad 6.2-liter V8 won't be around much longer. Instead, AMG is turning its focus towards a new, twin-turbo 5.0-liter V8 that will produce 570 hp and 665 lb.-ft. of torque, with output possibly reaching 700 hp and 885 lb.-ft. to replace the outgoing 612-hp V12 mill.
Forced induction is only part of the equation, as AMG is looking to a new hybrid-equipped V8, dubbed BluePower, that will either come with the X-Trac Flybrid system or a 100-hp electric motor integrated into the transmission. There's also talk that AMG will be releasing its own plug-in hybrid by 2012 and that diesels will continue to become an important part of the brand.
The other issue with which AMG has to contend is Mercedes' own turbocharged offerings. Future M-Bs will be sporting turbo'd V8s displacing 4.0-, 4.6- and 5.5-liters, with outputs ranging from 355 to 544 hp.
And what of the upcoming AMG supercar? Car says that the gullwing super coupe, codenamed C197, will debut in March of 2010 and be powered by the same 6.2-liter V8 (likely the last application of that engine) while sending all that energy through an eight-speed automatic gearbox.
Judging by the vast array of plug-in hybrids at the past few auto show, it's reasonable to assume that at some point in the next ten to 15 years there could be millions of vehicles plugging into our nation's power grid. The Michigan Public Service Commission will be looking at this issue over the course of the next several years as part of its effort to assess the state and region's future power needs.
The MPSC will use real plug-in hybrid electric vehicles to judge how the vehicles will effect the power grid at different times of the day, and the study will also gauge the possibility of plug-ins giving power back to the grid during peak times. The MPSC is inviting Detroit automakers, the utility companies, advocacy groups and others to participate in the ongoing study, and the group's first report is scheduled to go public in June 2009.
If the plug-in electric vehicle is going to be a major means of future propulsion, it's good someone is studying whether our aging power grid can actually handle the extra load.
General Motors, which has been blasted for having too many fuel-thirsty trucks and SUVs in the past, has recognized that the Chevy Volt has some serious momentum, and the Detroit automaker is redoubling its efforts to make the series hybrid a reality on time. Bob Lutz told us that the Volt would begin production by the end of decade, and despite Rick Wagoner preparing us for a missed deadline, Maximum Bob is reiterating his original 2010 deadline. Lutz points out that 400 advanced fuel scientists, 200 dedicated engineers and 40 designers are pumping heart and soul into the project, and we get the feeling failure is not an option. With skyrocketing fuel prices continuing to gradually increase and real consumer demand for a high mileage production vehicle growing, we're looking forward to Bob being right.
Shortly after the turn of the decade, Toyota expects sales of its hybrid vehicles to crest the one million unit per year mark. ToMoCo's goal may seem a bit ambitious considering that it's only sold about 1.25 million hybrids since the Prius' introduction in 1997, but the alternative-power push will mainly be fueled by sales of upcoming plug-in hybrid models and Toyota's aim to equip every vehicle in its lineup with a hybrid drivetrain by 2020.
Testing of the plug-in version of the Prius is about to begin in the U.S., Europe and Japan, equipped with a fancy-schmancy lithium-ion battery that's being developed by Toyota and Panasonic EV Energy Co. Sales should start around 2010, assuming that all is well with the power-pack, and we're expecting even more Synergy-Drive models to bow during the upcoming 2008 show season.
