Popular Post kscarbel Posted July 4, 2013 Popular Post Share Posted July 4, 2013 Always leading the country’s trucking companies in innovation and efficiency, Preston Trucking independently modified unit #2451, a 1980 GMC model J9C064 “Brigadier”, to create a highly aerodynamic road tractor. All modifications were made at the company shop in Preston, Maryland in 1981. The results were phenomenal. Equipped with a mechanically governed 290 horsepower Caterpillar 3406 tweaked by Alban CAT, Preston’s creation averaged 7.5 miles per gallon in regular service, aided by super-single drive tires and aerodynamic rear hub caps. At the Caterpillar-sponsored National Fuel Conservation Challenge in Peoria on September 22, 1981, with the nation’s leading trucking companies participating, Preston’s entry with driver Norman Bennett behind the wheel stole the event averaging 7.63 miles per gallon (The Preston fleet at that time averaged 5.7 mpg). The closest challenger was 6.91 mpg. For the contest, the truck was equipped with a 200 degree engine thermostat, as the philosophy of Preston’s maintenance staff was a warm engine is more fuel efficient. Friction-reducing synthetic oil was used in the transmission and drive axle. The belt-driven engine cooling fan was replaced by three electric fans which could be turned on progressively (individually) for optimized efficiency. The truck’s unique fiberglass aerodynamic hood was designed and produced in-house by Preston Trucking. “Winning the Fuel Conservation Challenge,” said Preston President Will Potter, “is a good example of what we’re trying to do to improve productivity, fight inflation and keep our rates at a reasonable level for the public.” Preston Trucking, “The 151 Line", was one of the finest trucking companies in the history of the United States (despite not having been a Mack customer). Preston people were of the highest character. The Preston slogan, “Our people make the difference”, couldn’t have been more true. Yellow Freight purchased the Eastern Shore-headquartered Preston Trucking in 1993. Yellow sold Preston in 1998 to new owners, who closed the 67 year old trucking company in 1999. . 4 Quote Link to comment https://www.bigmacktrucks.com/topic/31813-the-preston-aero-%E2%80%93-how-to-make-a-brigadier-slice-through-the-wind/ Share on other sites More sharing options...

kscarbel Posted July 5, 2013 Author Share Posted July 5, 2013 Great Coastal ran 250 horsepower Caterpillar 3406B-powered Freightliner FLTs governed at 1600 rpm that delivered superior fuel economy. Absolutely super people across the board at Great Coastal. It was troubling to see the company purchased by Heartland Express in 2002.

bulldog man Posted July 5, 2013 Share Posted July 5, 2013 Ive been a fan of the GMC Brigadier since I was a kid . , my family has owned them ... & I've owned my share w/ Cummins & Detroit in them & made a decent living w/ them also . always liked the looks of the Jimmy Brig till I seen these pics .I Seen these pics somewhere before & I thought it was ugly then . then again I thought the same of the CH Mack & T600 KW Anteater . & they slow grew on me im guessing this was a concept truck for Preston ? as these are the only pics of a Brigadier in an Aerodynamic style I've ever seen . & never seen 1 like it in person . it was definitely way ahead of its time .

Thanks.I drove an 84 Brigadier with a NTC Cummins 290 under the dash, we had to re seal the valve covers and you did the back one from in the cab thru the hole the doghouse covered up, it was overfull of engine and I'm sure a 3406 was the same way. 1 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/31813-the-preston-aero-%E2%80%93-how-to-make-a-brigadier-slice-through-the-wind/#findComment-192700 Share on other sites More sharing options...
kscarbel Posted July 10, 2013 Author Share Posted July 10, 2013 At the GM Heritage center lies proof that GMC pondered the production of an "Aero Brigadier". GM Design proposed the first truly all-new GMC Brigadier, which would have debuted in 1988. GM planned to use the then-new GMT 400 (C/K) light and medium truck cab. However, once the decision was made to sell GM’s heavy truck unit to Volvo, GM focused on its GMT 530 medium duty program (Topkick/Kodiak) then under development by GM’s UK truck unit Bedford for introduction in late 1989. Clearly, the Aero Brigadier influenced the GMC TopKick/Chevrolet Kodiak. Note: 1987 was the last year of the GMC-badged Brigadier (the Series 60 was an option that year). Volvo GM Heavy Truck Corporation, the successor to Volvo White Truck Corporation. began operations in January 1988. For year 1988, the Brigadier was manufactured by GM but marketed by Volvo GM, and carried the WHITEGMC nameplate. In 1989, the Brigadier was replaced by the WG model. Brigadiers were manufactured in Orrville, Ohio; Ogden, Utah (the former Autocar plant); and New River Valley, Virginia (the former White plant). Volvo GM developed and assembled several Brigadier engineering prototypes at their Greensboro, North Carolina headquarters, but nothing came of it. .

kscarbel2 Posted February 24, 2017 Share Posted February 24, 2017 Preston truck wins national honors The Star-Democrat (Easton, Maryland) / October 6, 1981 A specially-modified tractor from Preston Trucking, a company with local facilities, took top honors at the National Fuel Conservation Challenge competition in Peoria, Illinois, on September 22. The contest, sponsored by Caterpillar’s Engine Division, capped a nationwide series of events in which the U.S.'s leading trucking companies participated. The Preston tractor, aerodynamically modified exclusively by Preston employees at the company's headquarters in Preston, Maryland, easily won the challenge with a mileage per gallon figure of 7.63. The closest challengers posted a reading of 6.91 miles per gallon. The Preston fleet averages 5.7 miles per gallon. While Preston officials give much credit to their maintenance people for the victory, they also said that road driver Norman Bennett's effort was of championship caliber.. ."our engineering expertise could have been squandered by an inefficient driving performance." Company officials also pointed out that since the inception of a fuel conservation program, Preston' drivers have improved the company's over-all miles-per-gallon statistics by some 15 percent, resulting in a fuel savings of over 2.1 million gallons since May, 1979. "Winning the Fuel Conservation Challenge," said company President Will Potter, "is a good example of what we're trying to do to improve productivity, fight inflation and keep our rates at a reasonable level for the public." A company spokesman said the tractor's 3406 Caterpillar, 290-horsepower engine was equipped with a 200-degree thermostat specifically for the contest Quote Link to comment https://www.bigmacktrucks.com/topic/31813-the-preston-aero-%E2%80%93-how-to-make-a-brigadier-slice-through-the-wind/#findComment-362517 Share on other sites More sharing options...
Popular Post Underdog Posted February 24, 2017 Popular Post Share Posted February 24, 2017 Interesting... Fuel mileage numbers that would be enviable today, from 1981! And from a Caterpillar no less! An engine hardly known for fuel mileage. Seems to me 30 years later we should be getting 15mpg. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/31813-the-preston-aero-%E2%80%93-how-to-make-a-brigadier-slice-through-the-wind/#findComment-362522 Share on other sites More sharing options...
kscarbel2 Posted February 27, 2017 Share Posted February 27, 2017 As I mentioned above, Great Coastal ran 250hp Caterpillar engines in their Freightliner COEs that were governed at 1600rpm. They were engineered to lug and deliver great MPG, which they did. So it's no surprise to me that Preston did well with their eco-spec 290hp engine. Preston did not run Macks, but the company had the most wonderful group of people I've ever met.

Underdog Posted February 28, 2017 Share Posted February 28, 2017 I know a few former Preston drivers, and none have anything bad to say about the company. Yellow Freight, however, illicits a different response. Preston employees never forgave Yellow Freight for what they did to that company. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/31813-the-preston-aero-%E2%80%93-how-to-make-a-brigadier-slice-through-the-wind/#findComment-362858 Share on other sites More sharing options...

james j neiweem Posted July 8, 2019 Share Posted July 8, 2019 Loved those wide grills. GM along with Penske did the US a disservice by selling out to Volvo and Daimler. White wasn't at fault other than White management over extending themselves leading the company into bankruptcy. Mack and White should have followed the Paccar model slow and easy one step at a time. I wonder if yellow still has any Brigadiers left. Mack U's , Brigadiers , L 9000's and White 9000's were great competitors back in the day. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/31813-the-preston-aero-%E2%80%93-how-to-make-a-brigadier-slice-through-the-wind/#findComment-427263 Share on other sites More sharing options...

RoadwayR Posted July 8, 2019 Share Posted July 8, 2019 That orange dump is another set back axle prototype. I don't think any Brig's were sold so equipped, even under the WhiteGMC name. The Brigadier was replaced in 1990 by the White WG, probably not a move in the right direction......

RoadwayR Posted July 9, 2019 Share Posted July 9, 2019 The Brigadier was an inexpensive truck, mainly because it had been in production a long time and many units had been sold. Started off as the H/J series in 1966. The WG was a cheap truck because Volvo cut a lot of corners on it. Big difference.
