I don't understand the reference to Navistar. This engine is built by Power Systems International (PSI). I don't see any relationship between PSI and Navistar.

Since they claim it is a direct bolt-in for the previous 8.1L GM motor, that is entirely possible IF the current owner of the Workhorse brand and intellectual properties would simply re-introduce the R26 (UFO) chassis.

NOTE: that is a "big" if.

I agree with Steve. I think the only "relationship" is that Navistar MAY be a customer of PSI if they choose to use the 8.8L in some of their school busses.

The problem with the new engine is economy of scale, name recognition and market history that the current manufactures enjoy over any new competitor. We all like the idea improved performance numbers but are we willing to pay the price difference over what is currently available and are coach builders willing to risk going with what could be perceived as an unknown manufacture? Personally I hope they succeed in bringing the power train and chassis to market at a competitive price over what is available and poke a few manufactures in the eye doing so.

The engine is built by PSI, not Navistar. Navistar no longer owns The Workhorse chassis. It was sold to TMC in April 2014.

Exactly, International does make a gasoline engine any more and since they want to use it in IC products, they buy the engine just like Workhorse did with GM.

Should Workhorse Group, LLC buy engines from PSI, that has absolutely nothing to do with Navistar.

Navistar sold the entire operation and licenses to a company called "AMP" which has rebranded itself as Workhorse Group, LLC.

Workhorse Group currently operates a manufacturing facility in Union City, IN.

For availability and economies of scale...These engines are already made in large quantities for the industrial market (and LPG use in fleets - I think)
See: Industrial Engines | Power Solutions International, Inc. – Cleantech Engine Manufacturing

The EPA cert for "on-road gas" has been the hurdle for the last couple years. This reportedly can be a multi-million dollar process. I hope they can pull this off.

Especially significant since, as some might have read, the competition (Ford 6.8L V10 w/ 3 valve heads) just dropped their max HP from 362 (at 4,700RPM) to 320 (at 4,000RPM) on their new 2016's with the new-to-RV's 6 speed Torqshift. Odd since the 2 valve head version is still rated at 305HP.

I would LOVE to see a direct competitor to the F53! Competition typically means benefit for the consumer

My mistake, the holding company is AMP.

In my experience, gasoline engines loose power at higher altitudes. to the best of my knowledge, the PSI 8.8L engine is not turbo charged and as seen at the Louisville RVIA Exhibition will produce 265HP and is mated to an Allison automatic transmission. Unlike the previous year when the engine was first introduced, this example is fully belted with all the necessary driveline necessities and looks like it's ready to be lifted and installed in a chassis.
The spark plugs are featuring was appears to be Nomex (or equivalent) boots.
The exhibit is marketing in a banner that "It" is the most powerful gasoline engine in an RV chassis. The words "BIG BLOCK" are also prominently featured.

I can't speak to other diesels, but the 5.9 Cummins in my '89 Dodge W250 has 286k camper hauling trailer pulling miles on it, gets 18-23 mpg empty and 15-16 mpg with just the 11.5 Caribou on board at 70 mph, and 13.5-14 at 70 towing a Tracker. At this point the engine has had the starter and alternator rebuilt and I recently replaced the water pump and fuel lift pump because I was afraid they would fail somewhere far from home. Except for oil changes, filters, and belts that has been the total maintenance to the engine. IMHO, there are few gasoline engines that can match that overall, and it's still going strong.

Just my 2c.

Steve

Steve, Understand you're running a pre-DEF engine?

Thanks, DriVer for bringing me out of the dark ages. I just spent the last half hour or so learning about DEF and ours is definitely pre-DEF. I'm not sure I'd want to go post-DEF.

Steve
