According to FedEx, its hybrid delivery vehicles have saved approximately 83,000 gallons of fuel and eliminated 950 tons of greenhouse gas emissions while racking up an impressive 2 million miles overall. Because of this success, the global delivery giant will be adding 75 new hybrid vehicles to its fleet, making for a total of 172 hybrid vehicles. The hybrid trucks used by FedEx are said to improve fuel economy by 42 percent, reduce greenhouse gas emissions by approximately 30 percent and cut particulate pollution by 96 percent.

FedEx uses hybrid technology from Eaton, Isuzu, Iveco and Azure Dynamics with Ford engines and chassis. That's a lot of different systems for one company. Mitch Jackson, director of Environmental Affairs and Sustainability at FedEx, calls for "truck manufacturing industry to create its version of the Prius: clean, affordable and widely available for truck fleets."

FedEx also plans to test Class 6 vehicles using hybrid hydraulic technology from Parker Hannifin Corporation and replace some of their air fleet with more efficient Boeing 757 planes. All of these changes will result in less fuel consumption, helping FedEx's bottom line and, more importantly, reduce harmful emissions.

Corporate Express has announced that it will be one of the first U.S. companies to test an Isuzu hybrid delivery truck for its operations. The model will be a current Isuzu truck in which Enova Systems will retrofit their HybridPower drive system. The truck is expected to be completed in April 2008 and will be used in Los Angeles, CA.

The HybridPower system is described as a turnkey system that combines an enhanced electric motor and electronic controls to help power the vehicle, but there's no mention of the batteries. Enova has worked on lithium systems. Isuzu has currently other hybrid programs, including a large-scale commercial program in its homeland, Japan.

Last week, we told you that Isuzu and Toyota had announced that they were collaborating on a new small diesel engine. This week, they say that they are expanding that collaboration to also include new clean diesel exhaust technology. This agreement is between Hino Motors, Toyota's truck division, and Isuzu.

Although there have been some rumors that Toyota would like to get an Isuzu-designed diesel engine in their new full-size truck so that it can continue to compete in every market where its main rivals do, and these announcements sound like they could be baby steps towards that type of agreement, those rumors are just speculation. In the meantime, we can be satisfied that Hino Motors will be making their diesel exhaust as clean as they can.

Isuzu may not be particularly successful as a purveyor of cars - particularly in the US market - but they have done much better in the medium duty truck market and as a designer and producer of diesel engines. Their joint venture with General Motors to produce diesels under the Duramax brand for GM's heavy duty trucks has gotten excellent reviews.

Toyota and Isuzu agreed last fall to investigate building small diesel engines and they have now agreed to develop and build engines together. The first product will be 1.6L aluminum block four cylinder for European Toyota models and it's scheduled to go into production in 2012.

Since it's introduction for the 2001 model year the GM Duramax 6.6L diesel V-8 has been one of the most highly regarded truck diesels on the market. The engines were jointly developed with Isuzu Motors and built in a joint-venture plant in Dayton, Ohio. The DMAX plant has just produced the one millionth Duramax V-8. The 6.6L is four valve per cylinder V-8 with common rail injection and the 2007 version also has a particulate filter so that it can meet new emission standards. The engine is used in the heavy duty versions of the Siverado/Sierra pick up trucks, the Express/Savanna vans and also the larger medium duty Chevy Kodiak/GMC Topkick trucks.

After hooking up with Isuzu a couple of weeks ago, Toyota is now going to start taking advantage of Isuzu's diesel expertise. For the first time Toyota is going to combine their Synergy hybrid drive system with diesel engines. A diesel hybrid system has the potential to provide the best of both worlds. Hybrid systems really only provide a lot of benefit in stop and go driving where the regular deceleration can be used for regenerative braking to charge the battery. The battery is then used to re-start the engine after a stop and also to drive the vehicle when there is low demand and adequate charge. In highway cruising the limited battery capacity is of little value. A diesel engine works best in exactly those conditions, so a diesel hybrid should be the best combination of an internal combustion engine hybrid. The plan is for Toyota to offer a subcompact diesel hybrid as soon as 2010.

One of the technical highlights of the last generation GMT-800 full-size trucks from GM was the Duramax turbo-diesel V-8. This strong, efficient, refined engine was miles ahead of the Navistar engine in the Ford trucks and the Cummins engine that Dodge uses. The Duramax diesels are built by a General Motors-Isuzu joint-venture in Ohio called DMAX ltd. However, in the last year and a half, GM has been extricating themselves from most of their Japanese partnerships including Isuzu. Earlier this week, Isuzu announced that they were hooking up with Toyota and would work with Toyota on developing diesel engines for use in Toyota vehicles.

This caused the Japanese newspaper Nihon Keizai Shimbun to report that Isuzu was asking GM to sell their stake in the DMAX and another venture in Poland to Toyota. Today, both Isuzu and Toyota denied the report and in fact said that the issue had not even been discussed. The Japanese paper's report did say that the plant would continue to supply engines to GM after a Toyota deal, which would be critical to GM's truck programs. GM CEO Rick Wagoner is in Tokyo today so it remains to be seen what will happen.

Today, Toyota and Isuzu announced a collaboration which will be made possible by the former purchasing a 5.9 percent stake (100 million shares) in the latter. The two companies said in a public statement that the deal will allow them to work together in the research and development in three areas of green car technology. According to Automotive News (subscription required), Isuzu will take the lead in the development of small diesel engines and diesel emissions control while Toyota spearheads alternative-fuel drivetrains and environmental technologies for gas engines.

It seems as though most of the industry can't help but see an impending omen in the announcement. Just seven months ago, GM sold off the entirety of its stake (7.9 percent) in Isuzu in an effort to focus on falling profits in North America. And now, as Toyota makes one of GM's old alliances its own, the Japanese giant also gears up in an attempt to overtake GM as the world's number one automaker.

There's currently no word on the price of the deal, but it should hover somewhere around $354 million. "You have my word on it."

The Kathryn Kennedy Winery in Saratoga, California is a good example of how a green mindset can affect an entire business. I've never tasted the company's wine, but the sustainability information on their website makes me interested to see how the eco-conscious farmers there operate. The farm uses integrated pest management and on-farm composting, and the green attitude extends to the office, where the workers use recycled office supplies. All of the farm's vehicles are green, too, from the electric golf cart they use for small jobs and general transport to the B100-powered tractor out in the field. They say the tractor has not had any mechanical alterations and runs great. Even the family cars and the winery flatbed Isuzu NQR run on biodiesel. On the winery's website, the reasons behind the green vehicles are spelled out: "Our company has taken the position that America's intrenched [sic] dependence on petroleum is not only bad for the environment but also bad for our national security."

Diesel vehicle are receiving a lot of renewed interest in the U.S., and Isuzu's new diesel engine website is one more example of that. The site was launched to keep customers abreast of the new 2007 diesel emissions standards and, obviously, to promote Isuzu's diesel lineup. The site explains the features of Isuzu's 6H (7.8L) and the 4H (5.2L) engines and compares them to others. The company also enhanced its commercial vehicle website. The new diesel standards mean nitrogen oxide (NOx), hydrocarbons (HC) and particulate matter (PM) emissions must be 90 percent lower than the currently in effect 2004 standards. While some automakers have been forced to cancel their 2007 diesel vehicles in the U.S., Isuzu says it can meet the emissions standards because the low-emission technology has been in use in Isuzu trucks in Japan for the last two years.
