There's a variety of flavors of in-car networking standards that corral the large number of embedded computers and nodes present in the modern automobile. BMW Research and Technology, an R&D division of BMW, has found Internet Protocol up to the tasks that the other standards currently perform. BMW engineers used a standard PC and connected it up to the expected gear -- ECUs, engine and chassis control systems, even a multimedia server for the entertainment system. The reasoning behind using IP versus the more specialized protocols is to anticipate future needs and requirements, as well as reducing costs. Costs drop because fewer specialized components are needed, and the new version of IPv6 is even better than the more than fine performance from IPv4. It's a little spooky to think that your fly-by-wire throttle could be trying to chat with the engine using the same technology that we use to send instant messages, but IP proved itself capable enough even for critical safety functions. The research is ongoing, but BMW's work bodes well for adding functionality and decreasing costs. Adding aftermarket goodies should be fairly painless and service shops will also have an easier time of it by going with a more universal language. Imagine surfing the web with iDrive, though. Blech.

From 1990 to 2005, Nissan's carbon emission levels have grown more than any of the other top six automakers selling cars in the US -- and not by a little. The company's 2005 fleet is responsible for 9.2% more carbon output over its lifetime than the 1990 fleet, according to a study by Environmental Defense. The next highest gain was Daimler Chrysler at 4.8%, then Honda at 4.4%. GM -- often the whipping boy in studies like this -- had the smallest rise with 3%, and Toyota's comparative carbon output actually dropped 3%.

Not knowing the study's methodology, a host of factors could skew the outcome. Nissan replied to the study by saying "Since the end of this report in 2005, we have added the subcompact Nissan Versa, Altima Hybrid and flex-fuel-capable trucks." It's interesting to note, though, that Nissan has stood apart from the group of automakers fighting the CAFE battle in Congress, which is all about carbon emissions. It has also stayed out of the environmental debate spotlight, except to say that it is committed to being good to the earth. With Congress soon returning to the CAFE debate, Nissan might want to speak a little louder.

Thanks for the tip, Emanuel!

Faced with a bucket full of potatoes, cashew shells, hemp, rapeseed oil, wheat, and sugar beet, most of us would try and find some pigs to feed. If your name were Ben Wood, however, you'd snag that bucket, shells and all, add 20,000 British pounds sterling and make a car called the Eco One Speedster.

Designed by a researcher at Warwick University's Manufacturing Group, the department that works with industry, the car took Wood two months to build. The tires are partly made with potato starch, which creates less friction on the road. The brake pads are made from cashew shells blended into a resin, which means brake dust that doesn't hurt the environment. The body is fashioned from hemp and rapeseed oil. It's powered by a Triumph Daytona engine, which was not made from fruits or legumes, but steel. Yet that engine runs on fermented wheat and sugar beet, and still gets to 60 in under 4 and is good all the way up to 150 mph.

The car is 95% biodegradable or recyclable, that last 5% comprising things like its steering wheel, seat and electrics. It is nearly the ultimate expression of what can be done with food -- and we say "nearly" because it still has some plastic components that Ben says could be made from organic items. Ultimately, the aim is to race the car and convert many of its applications to motorsport. In the mean time, for those of you England-way, the car will be on show at the National Science Museum in London from August 28-30.

Honda took four categories in the latest J.D. Power's 2007 Automotive Performance, Execution and Layout (APEAL) Study. APEAL measures how happy an owner is with the design, content, layout, and performance of their car within 90 days of purchase. When the votes were tallied from the 91,000 respondents, Honda won with the Fit (Sub-compact), CR-V (MAV), Ridgeline (Mid-size pickup), and Odyssey (Van), beating Mercedes and BMW who both took three categories each.

Among the domestics, Ford was the only winner, with the Mustang and the Edge. According to J.D. Power, new or redesigned vehicles tend to score the best, and that cars that score well in the APEAL Study need lower incentives to lure buyers. And in case you were wondering, closely following another study that took the same measure of owner happiness, the Jaguar S-Type did not make the list this time.

"Accidents happen." It's the oft-quoted mantra of anyone who spends time behind the wheel. Sooner or later, you'll witness or partake in a vehicular mishap. The Japan Automobile Research Institute aims to take a less stoic attitude about accidents and have set up a model street to evaluate accident prevention systems and practices.

The model street, which is larger than three football fields, includes straight and curved sections and will offer Institute researchers better insight into the conditions that cause accidents. We can't speak for what causes fender benders in Japan, but in the US, the number one cause has got to be drivers with absolutely no training paying limited attention to the task at hand. Who can blame them? The allure of text messaging is so much more enticing than piloting a 3500-pound projectile rendered in metal, composite and glass. Familiarize yourself with good car-brandishing skills and then observe the idiots that surround you. There's no institute needed to discern that inattention and ineptitude often play roles, but there are often plenty of other factors. That's what the model street has been developed to study. Here's to safer travels for drivers and pedestrians alike -- and let's hope they export the stuff that actually works at reducing incidents.

High fuel prices and energy mandates bring all sorts of alternative fuel research and technology to the fore. University and government researchers recently whipped up a special blend of 13 enzymes and spices that releases hydrogen from a mixture of starch and water. There's no word on how it tastes, but it will definitely give you some pep, packing into six pounds the same wallop as a gallon of gasoline. The process produces hydrogen efficiently, so a vehicle using a hydrogen-powered fuel cell would only need to carry 12 gallons of water and 60 pounds of solid starch (96 lbs total), plus the enzyme blend, to achieve a 300-mile range. While this process appears to be an economical way to produce hydrogen in a manner quick enough for use in an automotive fuel cell, it does generate carbon dioxide. The reaction also requires a temperature of 86 degrees farenheit. Neither problem sounds as difficult as cold fusion, and the technique will be test driven in small fuel cells for mobile phones before testing in vehicles. Sugar water, pasta power, call it what you will, wouldn't it be nice to fizz up some power to get you on your way?

Much has been said about Hyundai's rise from being a pusher of Point-A-to-Point-B transportation to the purveyor of high value, safe and stylish vehicles. Nearly its entire lineup is full of ready for primetime hardware, save the Tiburon that idles into 2007 with merely a refresh of its aging design. The Azera debuted as a 2006 model to replace the XG350, a Korean import that filled a hole in the company's lineup but whose claws weren't sharp enough to play in the tiger pit that is the large car market in North America.

Like all the new models Hyundai has marched out in the past few years, the Azera looks great on paper and stacks up extremely well against other large cars in its class, like the Toyota Avalon, Ford Five-Hundred, Buick Lucerne and Chrysler 300. It starts with a low base price and piles on a big V6, lots of standard safety equipment and a sheetmetal suit that fits just right. But does the Azera have that something special that makes a contender into a champion, or do the sum of its parts equal no more than just the sum of its parts?
