Honda and Isuzu announce hydrogen partnership for heavy-duty trucks

TOKYO — Japan's Honda and Isuzu on Wednesday said they would jointly research the use of hydrogen fuel cells to power heavy-duty trucks, looking to expand fuel cell use by applying the zero-emission technology to larger vehicles. As part of a two-year deal, Isuzu will test Honda's fuel cell powertrain, which was designed for passenger cars, in Isuzu's commercial trucks, the companies said, which could pave the way for using the technology in a wider range of vehicles. Automakers are looking to develop more electric vehicles (EVs) to comply with tightening global emissions regulations. Many see battery-powered EVs as a solution for passenger cars in urban settings, but a growing number see hydrogen fuel cells as an effective way to power trucks, buses and other big vehicles. "Although we have done extensive R&D into passenger FCVs (fuel cell vehicles), we have not been able to study how best to apply the technology to commercial vehicles," a Honda spokesman told reporters at a briefing. "This partnership will allow us to do that." Fuel cell vehicles generate their own electricity using hydrogen stored in onboard tanks. This enables them to travel longer distances and refuel more quickly than battery EVs, while using less costly energy storage systems. "We think that FCV technology is well suited for heavier trucks which travel longer distances, and this partnership will enable us to examine this further," an Isuzu spokeswoman said, adding that the truck maker was also developing various lower-carbon powertrains including battery-electric technology for shorter-distance vehicles. With its Clarity Fuel Cell sedan, Honda is one of a handful of automakers which have developed and marketed fuel cell-powered passenger cars. Light- and medium-sized truck specialist Isuzu has for years has focused on diesel engine technology and has yet to market fully electric vehicles. But a price tag starting around $70,000 for the Clarity and scant hydrogen fueling infrastructure globally, Honda has seen limited take-up of that model and other FCVs since they began marketing them around 2015. In 2018 Honda sold just 654 Clarity FCVs, which are available only in Japan and the United States through leasing programs, compared with Honda's total annual global sales of 5.23 million cars.

Isuzu truck concepts include honeycombed ‘toaster on wheels’

Isuzu took to its hometown auto show to highlight its work in developing next-generation transport trucks, showing eight vehicles and four powertrain systems at the 45th Tokyo Motor Show. The most notable of the bunch are a pair of concepts: the FD-SI, a light-duty delivery truck designed around principles found in the insect kingdom, and the Elf EV, an all-electric version of its light-duty workhorse featuring a large-capacity battery with rapid-charging capability. From a design perspective, the FD-SI will get all the attention — much of it probably of the bemused sort. In truth, it looks like a futuristic toaster on wheels, a rolling box structure fitted with honeycomb patterns on the side panels and a glass cab windshield that seems borrowed from a heavy-duty construction crane. It turns out the honeycomb motif is no mere design whim; Isuzu says its designers focused on the "group intelligence" of insects and tried to apply that principle to the delivery vehicle. So the honeycomb exterior is replicated in the cargo space as hexagonal tube-shaped boxes, which the automaker says is a good compromise between strength and storage space. Inside the cab, the driver controls and seat have all been centralized, with the steering wheel retractable, to encourage smoother operability and more comfortable living space for the driver. "We want to support the drivers, the front-line people of "Transport," with unconventional ideas," Isuzu says. The Elf EV, on the other hand, is a zero-emissions, low-vibration delivery truck powered by a lithium-ion battery that'll take the vehicle at least 100 km, or 62 miles, on a single normal or fast-charge. It sports a 4x2, rear-wheel drive transmission with independent suspension in the front and leaf suspension in the rear. Here's a quick list of Isuzu's other Tokyo offerings: A 6x6 all-wheel-drive truck, featuring single wheels on all axles, built for rough terrain such as areas hit by major natural disasters. 80th anniversary editions of the Giga heavy-duty truck, geared with a remote monitoring system to transmit vehicle data for remote analysis to ensure safe driving; the Forward medium-duty truck, which boasts 10 percent higher fuel economy than its 2015 version; and the internal-combustion version of the Elf light-duty truck, which is sold in the U.S. as the N-Series.

GM-Isuzu joint venture assembles 1.5-millionth Duramax diesel

General Motors and Isuzu have officially stitched together 1.5 million Duramax 6.6-liter diesel engines. The joint venture between the two manufacturers started in 1998, and now the DMAX plant employs 517 workers in a 584,000 square-foot facility. GM introduced the Duramax turbo diesel engine to the US market for the 2001 model year, and it can be found trucks like the Chevrolet Silverado HD and GMC Sierra HD as well as the full-size Chevrolet Express and GMC Savana vans. In its current configuration, the engine yields 397 horsepower and 765 pound-feet of torque at just 1,600 rpm.
Of course, the big oil burner has plenty of tuning potential as well. As you may recall, a Duramax-powered truck recently set the land speed record for towing a vehicle at 142 miles per hour.
GM owns 60 percent of the joint venture, with Isuzu laying claim to the remaining 40 percent. The facility is located in Chicago. You can take a look at the brief press release below for more information on the milestone.
