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.

Cummins and Isuzu to collaborate on prototype electric truck

Cummins, the company known best for its diesel engines, just announced a partnership with Isuzu to “create a prototype medium-duty, battery electric truck” for North America. Exploration of electric powertrains isnÂ’t totally new for Cummins, as itÂ’s talked about a transition to electric since 2017. In fact, Cummins even revealed a battery-powered truck back then, too. This electric truck with Isuzu is new, though, and itÂ’s going to put the Cummins PowerDrive6000 powertrain into IsuzuÂ’s F-Series truck that you can see in the photo above. Cummins does not detail specs for its PowerDrive6000, but weÂ’ve seen the drive unit used in a hybrid concept from Cummins previously. It provided 50 miles of electric range when the battery pack in that truck was full, but with this being a full battery electric vehicle, we suspect that Cummins and Isuzu are using a much larger battery pack for more range. We donÂ’t have any vital specs like range or power, but we suspect those will come at a later date. This year will see Isuzu and Cummins put the truck through a pilot and demonstration phase in North American fleets. After thatÂ’s been completed — assuming it is successful — the partnership could see Isuzu and Cummins collaborate on building battery electric trucks for commercial use here in North America. “We are excited to be working with Isuzu to accelerate decarbonization within the partnership,” said Amy Davis, Vice President and President of New Power at Cummins. “ItÂ’s through our joint commitment in innovation that we provide our customers with safe, reliable zero-emissions solutions.” Related video:

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."
