The deadline for automakers to comment on the latest CAFE standard proposal is today, and at least one manufacturer has decided to speak up. BMW is calling the fuel efficiency standards it would be required to meet 'unattainable.' As you may be aware, the latest proposal takes into account the overall footprint of the vehicle, and manufacturers which sell large vehicles won't be required to meet the same goals as those which produce smaller vehicles. While that's great for manufacturers with truck-heavy lineups, automakers like BMW are in for a world of hurt as they tend to produce smaller, sportier machines. For this reason, BMW would be required to average 37.3 miles per gallon for its cars, quite a bit higher than the 35.7 mpg industry average. The Bavarian's trucks would need to achieve 31.7 mpg, compared to an industry average of 28.6 mpg.

While it may seem a bit unfair (or maybe not) that BMW should be required to hit higher numbers than some other manufacturers, it should be pointed out that BMW currently offers no engines with fewer than six cylinders and is on a bit of a crossover binge as of late. What's more, the marque has proven rather adept at squeezing high power outputs from relatively small displacement, so we'd stop a bit short of suggesting that the numbers being asked of it are unattainable.

During a media preview of the new BlueTec diesel powered Mercedes SUVs here in Vermont, Thomas Ruhl Director of R-Class, SUV hybrid and BlueTec discussed some of the alternative drive systems coming from Stuttgart in the near future. While he didn't get into any of the electric car programs that have been discussed recently, he did talk about hybrids. Ruhl confirmed that the S400 BlueHybrid and ML450 BlueHybrid will be launched in the U.S. in 2009. BlueHybrid does not mean these are diesel hybrids, Blue is just the color that Mercedes and others are using to denote their cleaner, more efficient vehicles. When a diesel hybrid arrives it will be called a BlueTec Hybrid.

The S400 will use the mild hybrid system jointly developed by Mercedes and BMW and will be equipped with a lithium ion battery. The ML450 will be the first Mercedes application of the Two-Mode hybrid system. General Motors is building the Two-Mode hybrid transmissions for its own applications as well as supplying Chrylser. Similarly, Ruhl revealed that Mercedes would build the Two-Mode transmissions for both its own and BMW's vehicles. The X6 will be the first Munich model to get the hybrid treatment. The guts of the Mercedes-built units will be identical for both German brands and, like the American version, the only difference is the mechanical interface to connect the respective automakers engines as well as the control software. One item Ruhl declined to discuss is the battery for use with the Two-Mode hybrids. GM and Chrysler are both using nickel metal hydride. Mercedes is using lithium ion for the mild hybrid and the 'no comment' from Ruhl indicates that the same may be true for the Two-Mode.

While Mercedes-Benz is a leader in clean diesel technology, the German luxury brand has been lagging behind its arch-rival BMW when it comes to the adoption of green technology such as stop/start in its lower-end models. This omission will soon change, as the A-Class and B-Class models, which are not sold in the U.S. market, will be granted the technology shortly. While consumers will likely appreciate the fuel savings most, the brand will be happy to report the reduction in carbon dioxide, which is regulated in most of the world.

The stop/start technology that will be used by Mercedes-Benz is a very basic system and is shared with the smart brand. Because the starter will be used much more often than normal, a larger starter motor and battery is required. BMW harnesses a portion of the energy usually lost when braking to recharge this more powerful battery. Mercedes' system does not allow this capability, though the automaker claims it is hard at work on the next-generation version of this technology which they say will incorporate regenerative braking.

In the race to bring hydrogen-fueled cars to market, virtually every manufacturer has settled on the compressed gaseous form with one notable exception. BMW has been the lone holdout for the use of liquid hydrogen. BMW's rationale is that liquid hydrogen is more dense than hydrogen gas, even when compressed to 10,000psi. Unfortunately getting hydrogen into liquid form, requires chilling it down to -282.57C -252.87C. Keeping it at that temperature requires a lot of insulation and hence a very bulky storage tank. Nonetheless, insulation is not perfect and the liquid hydrogen still warms up over time and boils. The vapor hydrogen then has to be vented to atmosphere. A BMW Hydrogen 7 left sitting for a week will end up with an empty hydrogen tank.

BMW has been working with a consortium of 34 automakers, aerospace, fuel companies, and universities for the past four and a half years to develop a new storage system for liquid hydrogen. The current cylindrical steel tanks are both heavy and challenging to package in a car and end up absorbing most of the trunk space. BMW's research and development arm Forschung und Technik, along with the consortium, has developed a new composite modular design that can be formed into different shapes allowing greater packaging flexibility. The new tank is claimed to be one third of the weight of the current tank design. It's not known if the new tank does anything to address the issue of fluid boiling. BMW will display the new tank at the StorHy conference in Poissy, France this week.

Last year, Lexus became the first automaker to introduce a production eight-speed automatic transmission in the latest LS460. Recently, German transmission manufacturer ZF announced a new eight-speed of its own which is claimed to provide a 14-percent boost in fuel efficiency compared to a five-speed. It looks like Audi and BMW will likely be the first to directly challenge Lexus when they start using the ZF. Audi may be first out of the gate in 2009, with eight-speed installations in the A8, Q7 and the expected A7 coupe. BMW will probably follow a year later with the X6 and the next-generation 7 series getting the extra gears. Mercedes-Benz already has a seven-speed that it builds on its own. Mercedes' powertrain chief admits that an extra gear could be added to the unit but that the incremental improvement would be limited. As more gears are added, the weight and complexity of the system increases and the improvements become smaller and smaller. Seven and eight-speed transmissions will likely remain the maximum for the foreseeable future and six-speeds will probably take the bulk of volume in mainstream segments.

We've seen the renderings - some fanciful, like the ones above, some unsurprising - and heard the rumors about the new all-electric BMW/iSetta vehicle. If we trust the phrasing in a short story in Global Insight (no direct link, sorry; found the story in Lexis Nexis thanks to the EDTA), then we can celebrate a new development at BMW. The story, written by Tim Urquhart, starts, "BMW will give the green light to an all-new zero-emission vehicle (ZEV) city car that will see the premium carmaker enter an all-new segment." This fits with the news that came out about a month ago that said that a decision would be made sometime this year. The new EV - which might be called the iSetta or potentially co-branded (?) with Smart - will likely have li-ion batteries. We're ready for some official confirmation on this one, don't you think?

They're doing it again. Somebody out there has come up with yet another rendering of what the new electric Isetta from BMW might look like. In contrast to the other ones we've shown you, this looks more like the BMW of today rather than the Isetta of yesteryear. The fancy speculative drawing appeared on AUTOCAR.co.uk along with conjecture that the city car could be powered by a rear-mounted petrol (or possibly diesel) engine in addition to the battery model. It could even have a BMW motorcycle engine. Since there is a strong possibility the car will be based on the underpinnings of the Mila Alpin concept and that its maker, Magna, is currently hard at work on a plug-in hybrid, we feel this seems a likely powertrain option as well.

The article goes on quote BMW CEO Norbert Reithofer as saying, "co-operation [with another car maker (*cough* Mercedes)] is possible" and added that the decision would be made by the end of 2008 "whether to go it alone". With a target production date of 2012 we expect an officially official announcement and drawings any day now.

Pretty soon, we're going to have to list the people who aren't driving a BMW Hydrogen 7. BMW is offering the car to celebrities, average citizens and politicians the world over. Some of us get to drive it around the block, others get to keep it for a week or two. The latest to be handed the keys is EU Parliamentary president Hans-Gert Pöttering (pictured), who stepped into the car yesterday in Strasburg. BMW says (after the jump) that this move was "In line with the European Parliament's efforts to take measures to reduce its own CO₂ emissions." Pöttering will use the car for work-related trips. For his part, Dr. Norbert Reithofer, Chairman of the Board of BMW AG, said the Hydrogen 7 "shows that we have initial solutions and are on the right track" and that for "regeneratively produced hydrogen has the most potential to secure our mobility in the future." Potential, always with the potential.

When we first heard about the new mono-fuel BMW Hydrogen 7, we were rather impressed by the extremely low emissions numbers posted by the model when tested at Argonne National Laboratory. The fact that BMW was able to reduce the emissions, boast better range and make more power as compared to their previous-generation Hydrogen 7 was pretty cool. According to Dr. Thomas Wallner, lead engineer in Argonne's hydrogen vehicle testing activities, "[The Hydrogen 7's] engine actively cleans the air. Argonne's testing shows that the Hydrogen 7's engine actually shows emissions levels that, for certain components, such as Non Methane Organic Gases (NMOG's) and Carbon Monoxides (CO's), are cleaner than the ambient air that comes into the car's engine."

So, because air is required for the hydrogen combustion, and there are pollutants already present in the air, at times the exhaust from the BMW is cleaner than the air it took in. Does that warrant BMW referring to their hydrogen-burner as a "pollution-consuming internal combustion engine?" Perhaps we're just picking nits, but that sounds a wee bit like greenwashing. It's not like the overall air is cleaner after going through the system, after all. Read their entire press release after the break.

So far all the Hydrogen 7s that BMW has produced and distributed have been dual fuel vehicles that are capable of running on either hydrogen or gasoline. This is helpful since the H7 only has a range of about 100 miles from its tank of liquid hydrogen. BMW has now built a mono-fuel hydrogen only version of the H7 that has been optimized for running on the alternative fuel. By not having to compromise the engine to run on gasoline, BMW has been able to improve performance, reduce fuel consumption and extend the range. The mono-fuel H7 was recently tested at the Argonne National Lab which found out the exhaust gases were actually cleaner than the ambient air going into the engine. BMW will release more specifics about the mono-fuel H7 in two weeks at the SAE World Congress. For now, the mono-fuel H7 is just a tech demonstrator with no production plans.

Since the debut of the original BMW M3 in the mid-eighties, the high-performance editions of most of BMW models have garnered plenty of praise for their dynamic abilities. Unfortunately, over several generations, the M3, M5, and M6 have grown progressively porkier as they have grown more powerful. The engines have grown from the original four and six cylinder units to six, eight and then ten cylinder units.

As gas prices continue to climb and revised CO₂ and fuel consumption regulations hover on the horizon, BMW looks set to join the likes of Volkswagen, Ford and others as displacements and cylinder counts are reduced. BMW has already introduced turbocharged four, six and eight cylinder engines in recent models and these engines, combined with reductions in mass, are likely to result in both increased performance and efficiency in the next generation models from the M division.

The rumors of BMW's new green brand have been circulating for months. We talked about the possibility back in January and November. A bit of news came in early February with the discussion of a revived Isetta small car. Automotive News (subs req'd) is now reporting that the Isetta rumors - or, as one of our readers said, iSetta - might be coming true. BMW CEO Norbert Reithofer told AN that a 12-member planning group called "Project i" has been working behind the scenes for about a year to discuss forming a new brand just for BMW's alternative-fuel vehicles. Reithofer said that the group, "Is fully independent and even free to act beyond BMW structures if necessary." BMW may build a small EV and if it does, the badge is just as unknown at this point as the look and battery type.

Of course, there's no reason BMW can't find religion on just greening up the BMW brand itself. I mean, a 520d gets better mileage than a Prius, don't ya know? Would an all-electric BMW city car be too much brand dilution?

Efficient Dynamics has claimed its first scalps of the year, taking the World Car of the Year Green Award. The three finalists were all Rudolph's children, being of the diesel variety: the BMW 118d, the smart fortwo cdi, and the Volkswagen Passat 1.9 TDi BlueMotion. The specific rationale for choosing the BMW wasn't given, but the roominess, real world practicality, miserly emissions and fuel needs, and Efficient Dynamics are probably all good suspects. It's a nifty little car and a well deserved award, so kudos to you, BMW. Now if you could get that diesel Isetta going, we'd really get to cheering for you.

When I (an American) think about the Lexus brand, the first thing that comes to mind is not its hybrid option. In Europe, it seems Lexus and hybrid are synonymous because a Lexus official told the BBC, "Hybrid is Lexus brand defining technology." We have written about the increasing Lexus hybrid sales in Europe over the years and even the shocker that hybrid Lexus vehicles were outselling the gas versions 4-to-1 in Europe. Sainsbury's chief executive, Justin King, gave up his Maserati Quattroporte for a hybrid Lexus. Overall, though, Europeans still love diesel and aren't big fans of hybrids. Also, and you might find this hard to believe (he wrote sarcastically) but Europe already has one (or two?) luxury car brands.

So, why is the Lexus hybrid doing well in Europe when hybrids and even Lexus is not doing well? Complete lack of competition! "Only Lexus has hybrid, and we have three while others have yet to launch one" the Lexus company official said. Lexus was the only hybrid we could recommend to Yoko Ono when she lamented the lack of a comfortable hybrid because, as the BBC notes, Audi, BMW and Mercedes don't currently sell a hybrid.

So, word to GM and Ford (two companies apprehensive about hybrids in Europe), here's how you get hybrids to work in Europe: make them high-end. Diesel is "a more honest technology" than the hybrid system, said BMW's outgoing sales and marketing director, Stefan Krause. Still, we'd rather see a hybrid BMW on the sales lot than more concepts.

The BMW Hydrogen 7 "green" message is going to Asia. While many of the cars are still tooling around Hollywood with various celebrities at the wheel (who's the latest? check back in a few hours), five have been sent to Singapore for a two-and-a-half-week promotion. Two government representatives, the Minister for the Environment and Water Resources, Dr. Yaacob Ibrahim, and the chief of Singapore's national environment agency, Mr. Lee Yuen Hee, came to the BMW CleanEnergy pavilion a week ago to kick off the event. Like the celebrity vehicles here in the U.S. and Europe, the dual-fueled 7 Series will be used to ferry VIPs around Singapore. One, though, will remain on display "in a futuristic, glass-and-steel pavilion located on state land in the heart of Singapore," to make sure everyone gets a chance to be awed at just how unavailable the hydrogen economy is. The vehicles will be in Singapore until the 23rd. There's more after the jump.
