Isuzu To Outsource Cummins Diesel Engines For Its Upcoming Truck Line

Japanese automaker Isuzu Motors is set to tap U.S. engine producer Cummins for its line of diesel powerplants in future Isuzu commercial trucks. Isuzu currently supplies the Low Cab Forward (LCF) truck line to Chevrolet, which means future Chevy LCF models may feature Cummins power.
In a recent post, Nikkei Asia reports that Isuzu will turn to Cummins for its diesel engines, which will be used in Isuzu’s “medium-size trucks requiring high horsepower.” It’s reported that the Cummins-powered Isuzu trucks will arrive in North America sometime later this year. The move is expected to save Isuzu tens of millions of dollars annually in research and development, which will help it focus on EV and next-generation technology.
Isuzu currently offers two commercial truck lines, including the N-Series, which Chevrolet sources for its LCF 3500, 4500, and 5500 models, and the Isuzu FTR, which Chevy sources for the LCF 6500XD.
As GM Authority exclusively reported last year, Chevy may be gearing up to offer a new LCF 7500XD Class 7 vehicle with a 33,000-pound gross vehicle weight rating (GVWR). The new 7500XD will be based on the Isuzu FVR, and it’s speculated that the Cummins diesel engine mentioned above will be found under the hood of an even bigger model.
Both the Isuzu FVR and Chevy LCF 7500XD are expected to launch with the same 5.2L four-cylinder diesel engine found in other variants of the Chevrolet LCF line. Standout features for the oil-burner include 215 horsepower at 2,500 rpm and 520 pound-feet of torque at 1,650 rpm, as well as DOHC, 16 valves, a cast-iron block, and cast-aluminum head.
Now, however, it looks as though a new Cummins diesel engine will be offered either parallel to the 5.2L four-cylinder diesel, or as an outright replacement in a new model line. Furthermore, it’s possible that a Chevy LCF truck line equivalent could offer the Cummins diesel engine as well.

Why did it take 3 model years for the brain trust at Isuzu to figure out that a 5.2 liter 215 HP 4 cylinder engine was not enough to climb the various hills and low mountains around the country? Even my Hino SG with the big 6 cylinder and 230 HP was barely enough to do the job. The only saving grace was that i had a 9 speed trans. You need at least 250 to 275 HP to climb the mountains in the west without slowing down. The Cummins will do the job as long as they offer a 7 speed trans with at least 250 HP.
Because these things are engineered and mostly sold in Asia where speeds are slow. The brain trust lives in a country where trucks have a 80 km/h (50 MPH) national speed limit.
The whole cab-over is because their country doesn’t have any space to turn trucks, and that constrains powertrain volume and factors like cooling.
If you want to drive fast, buy American.
re »buy American« — just beware that besides Paccar, they are all foreign owned.
Who owns paccar.. ?
Who owns PACCAR? Good question. I can’t find any information on a single most important and dominant shareholder.
I guess, the Paccar stock is traded on the New York Stock exchange.
Japan and Korea are essentially mountain ranges surrounding by coast.
This relates to a new, bigger sized rigid that they currently don’t make.
BTW, Cummins has a factory in China.
Cummins to the Rescue! BTW, they’re all over the World making Engines!
I wonder which cummins engine will it be? If it’s the 6.7, then why wouldn’t they use the 6.6 duramax? Besides Isuzu owns 40% of D-MAX and it’s already being used in Silverado MD.
Maybe because the Duramax plant has a hard time keeping up with demand as it is! I am thinking Isuzu might be interested in the ISL series, it’s about the same size and output as the Isuzu 6HK1. If Isuzu wanted to offer a tandem axle or tractor the ISL would be a better choice than the ISB. Anyone notice that Hino stopped selling new trucks in the U.S. for the remainder of 2021? They can’t get their engines to pass EPA/CARB regulations. Going with Cummins will save Isuzu a lot of money. Hope there is a Chevy version!
This is needed here stateside with higher speeds and mountains. A 6.x liter inline six would work nicely in these trucks.
I’m paying attention to the diesel line because I expect a new diesel engine to be put in their fine Savanah and Chevy vans which I hope they do not turn into UGHLEE dawgs like Ford and Ram. The 4 cylinder diesel is a fine engine but is a bit too small for them if you ask me.
Whatever happened to Duramax Engines They’re Joint venture between Isuzu and GM? Whom? Anyway Cummins has more engines to choose from than Duramax could ever produce!
What I can’t stand is that engine builders are now being outsourced to other countries to produce our products. I’m not against producing diesel engines in various parts of the world for various markets around the world, but what’s wrong with building here in the USA for the USA, Canada, Mexico, and possibly Central and South America? Why would anyone rely on one factory to produce one product for every country in the world? There is no such thing as “One Size Fits All”.
