Click the S400 hybrid prototype for a high-res gallery

An attentive Autoblog reader spotted what appears to be a prototype Mercedes S400 Hybrid in a Houston Texas parking lot the other day. The test car's badges were all taped over, but the S400 and hybrid badging on the trunk lid seems to match the show concept. The S400 was shown at the Frankfurt Motor Show last fall and will launch into production in mid-2009 at about the same time as the ML450 Hybrid. While the SUV will use the Two-Mode hybrid system developed with GM, Chrysler, and BMW, the S400 will use the mild hybrid system created with BMW. The mild hybrid uses a 15kW motor sandwiched between the transmission and 3.5L V6. The Mercedes mild hybrid system is likely to be the first mass production hybrid with a lithium ion battery. At the auto show introduction, Mercedes claimed that the full-size hybrid luxury sedan will achieve nearly 30 mpg.

Ever since the initial hybrid version of the Saturn Vue, the "different kind of company" chose to go its own way by badging its fuel-saving wares as Green Lines. This designation will be going the way of the Dodo in favor of the much more simple and recognizable designation of simply "hybrid." The reasoning is that the Green Line badge adds unnecessary confusion to Saturn's line of vehicles and is too long for marketing purposes. This becomes especially true as General Motors rolls out new versions of its hybrid technology. Soon, the Saturn Vue will be granted the sophisticated 2-Mode technology as is used on full-size SUVs from GM such as the GMC Yukon, Chevrolet Tahoe and Cadillac Escalade. While the current Vue is well priced considering its decent fuel mileage of 25 mpg in the city and 32 on the highway, the new 2-Mode model will be capable of powering the vehicle on electricity alone and should be available in 2009.

Liquified petroleum gas (commonly referred to as propane) has never really caught as a motor fuel in the U.S. although it is used by some fleets. However, drivers in Australia may have a new LPG-fueled vehicle to choose from. In fact they may have an LPG mild hybrid available soon at Hyundai dealers. Hyundai Australia is considering local production of the LPG hybrid Elantra that goes on sale in Korea in 2009. Australia has sufficient domestic supplies of LPG that they don't have to import any. With 3,200 LPG filling stations, Australia significantly outnumbers the 2,500 stations in the US.

Even though consumption on LPG is slightly higher than gasoline, the total operating costs of an LPG hybrid Elentra are significantly less than a Prius. In Australia, LPG is $3.26/U.S. gallon less than gasoline. That means an average driver could operate the LPG hybrid Elantra on less than $10 a week. Hyundai has field tested about 100 LPG hybrid Elantras and is reportedly close to finishing validation of the system. The mild hybrid Elantra uses a 15kW motor, LG Chem lithium ion battery and 1.6L engine. The LPG hybrid is thought to get about 47mpg (U.S.) compared to 53mpg for the Prius. Gasoline currently runs $5.80 a gallon in Australia and an LPG mild hybrid could be much less expensive to operate. Hyundai is also developing both plug-in and non-plug variants of a strong hybrids and could begin limited production of a fuel cell vehicle by 2012.

While the issue of the nine-thousand recalled batteries from Cobasys remains a bit murky, General Motors may be inclined to just purchase the troubled battery-maker altogether. While we're not entirely sure that another money-losing operation is exactly what GM needs right about now, we can be sure that GM needs those nickel metal hydride batteries for its current range of mild hybrids. Right now, Cobasys is co-owned by Chevron and Energy Conversion Devices, though the two companies have been bickering a bit as of late regarding their joint-ownership responsibilities. It was revealed in court that some sort of offer to purchase Cobasys was being considered, which put an early end to those proceedings.

It's difficult to say what impact the purchase of Cobasys could have on future hybrid offerings from General Motors. We're certain, though, that fuel efficiency is on the minds of consumers these days, so we'd be surprised if GM didn't have big plans for the fuel-saving technology in the near future.

It's no secret that General Motors' hybrid sales are nothing to brag about, especially when compared to cross-town rival Ford and, especially, cross-ocean rival Toyota. While the overall sales direction is positive, sales were most certainly negatively impacted by a problem with battery packs manufactured by Cobasys which were intended for installation in mild hybrid versions of the Chevrolet Malibu, Saturn Vue and Saturn Aura. According to reports, some nine-thousand batteries had to be recalled and replaced due to an internal leak which made the entire pack inoperable. Although the vehicles themselves would still operate, the hybrid system would not.

GM spokesman Tom Wilkinson put it well when he said, "I don't know how many hybrids we could have sold, but we would have had at least 9,000 more batteries for the pipeline." There appears to be light at the end of the tunnel, though, as Cobasys claims to have resolved the problem and Chevrolet reports that production of the 2009 Malibu hybrid is on target for June 23.

Car-obsessed Americans will get another chance at the historic Alfa Romeo brand soon enough, as the company is planning on a resurgence for the U.S. market. As is the current trend among automakers, along with the beautiful range of automobiles that the Italian marque will be bringing to our shores, it plans on offering a crossover as well. Expect something in line with BMW's current utility vehicle offerings. What's more interesting to us at AutoblogGreen, though, is a possible hybrid system snagged from Fiat, which owns Alfa. Even if the full hybrid drivetrain is left off the docket, at the very least, a mild hybrid system in the form of stop/start will almost assuredly be available.

As an aside, take a good look at the Kamal concept from 2003. Looks a bit like the Subaru Tribeca before its last redesign, wouldn't you say?

Below the fold are three videos I think you'll find interesting. The first video is from the Aptera launch party. The Aptera video has lots of cool music and people enjoying the debut of this very cool car. The second video below the fold is filled with Nissan's concept cars. The Nissan concepts are debuting at the 2007 Tokyo Motor Show and the video includes the cool interior of the Round Box roadster. The third video is the Smart ForTwo Hybrid. The mild hybrid system makes the tiny smart that much greener.

Last year, Mercedes-Benz announced that in addition to working with GM and BMW on the Two-Mode hybrid system, they would also collaborate with BMW on a less complex mild hybrid that could be adapted to most of their vehicles. The first product of that collaboration is being displayed this week at the Frankfurt Motor Show. A pair of S-Class sedans with the mild hybrid system are on display in S400 and S300 Bluetec guises.

The S400 hybrid uses the 3.5L gasoline V-6 and has a total combined output of 299 hp/ 375 Nm with the electric assist. As you might expect, the S300 Bluetec hybrid mates the 3.0L Bluetec diesel V-6 to the new mild hybrid set up to peaks out at 560 Nm of torque. The two luxury sedans reach 29.8 mpg and 43.6 mpg (both in US gallons) respectively. That latter number is particularly impressive considering the girth of the S-Class.

The hybrid system itself consists of an electric motor/generator/starter sandwiched between the flywheel and transmission. It can provide power boost, start/stop capability, and regenerative braking. Energy is stored in a small lithium-ion battery pack that is mounted under-hood. This would make the S-Class hybrids the first such production vehicles to use a lithium battery. The S400 is due on the market in 2009 with the S300 a year later.

Today, we will be listing the top ten easiest to implement green technologies that already exist today. Now, this is a rough list, every car is different and not all of these technologies are applicable to each one. But, let's take a look at each one and see what gains there could be from them, starting with the easiest one, LED bulbs.

LED stands for light emitting diode, and they are already common in all types of devices. One very desirable trait that they posses is that they last a very long time. They also can be quite bright. Additionally, the bulbs draw very little electricity, which paves the way for some of our other gas-saving technologies later on the list.

Next on the list are smaller wheels. With DUBS being ultra-hip these days, I'm not going to go crazy and say we should all go back to fourteen inch wheels. But, style is getting in the way of substance when our wheels get much larger than seventeen or eighteen inches. Also, consider going narrower! Wide tires convince some that the car must be faster. In reality, most of the time they are just using more gas.

Keep reading after the jump for the rest of our commentary.

At the Chrysler's What's New preview of their 2008 lineup at their Chelsea, MI Proving Ground, executive VP of product development, Frank Klegon spoke about some of the companies powertrain plans for the next few years. While he didn't really get into too many specifics he did have some interesting things to say. Chrysler is definitely more bullish on diesels than their Detroit counterparts.

Over the next five to ten years Chrysler is predicting that diesels will reach a 10-15 percent share of the US market and hybrids will reach a similar penetration rate. Klegon also gave the assembled group a preview of what's coming as part of Chrysler's powertrain offensive in the next few years - now that the ownership question is settled they are moving full speed ahead.

The new aluminum block Phoenix V-6 engine family will get a six to eight percent improvement in fuel economy thanks to cylinder deactivation and dual variable valve timing. Further efficiency improvements will come thanks the new dual clutch gearboxes that will be mated to the new engines.

You can read about Chrysler's diesel and hybrid plans after the jump.

Parallel hybrid; serial hybrid; full hybrid; two mode hybrid; mild hybrid and now... micro hybrid. Yes, one more competing technology has entered the fray, with its very own nomenclature. The technology behind the stop/start system that is apparently being readied for the Smart FourTwo is nothing new to our readers. The start/stop Smart will have a 1.0-liter engine with 71 hp and a 5-speed sequential gearbox. Hybrids have the capability of turning off the internal combustion engine when it's not needed, and BMW has implemented a similar scheme for their non-hybrid models.

All of these competing technologies beg the question: what exactly is a hybrid? Perhaps I'm being too picky, but to me, a hybrid is not a hybrid unless it is capable of moving itself using either power source, be it electric, gasoline ICE, diesel ICE or hydraulic. But, anything that helps raise the fuel economy of any given vehicle is a good thing, even if they do call it a "micro hybrid". I wish we could get a diesel Smart over here, though.

The new Saturn Aura Green Line hybrids are now rolling off the assembly line at the General Motors Kansas City assembly plant and should start showing up in dealerships shortly, and with any luck in the AutoblogGreen garage as well. As tax day approaches the IRS has certified that the Aura is eligible for a tax credit of $1,300 which buyers this year will be able to take off on their tax return next year.

In addition to the tax credit, the hybrid Aura gets the lowest base price of any hybrid available on the US market this year, starting at $22,695. The EPA has also given the Aura an mileage rating of 28/35mpg city/highway. The Aura gets the same mild hybrid power-train as the Vue hybrid and the upcoming 2008 Malibu hybrid. The 2.4L four cylinder has a belt-driven starter alternator, start-stop capability when the vehicle is stopped and regenerative braking. The GM press release is after the jump.
