Chevy Colorado Z71 Trail Boss 3.0 concept heads to SEMA

Chevrolet is presenting a new take on the Colorado pickup at the SEMA show this year. The show truck picks up where the Colorado Z71 Trail Boss Edition leaves off, with numerous accessories from the parts catalog as well as several custom additions. The SEMA truck is based on a Crew Cab model with four-wheel drive, painted red with rally stripes. Among the features added from the catalog are a sport bar with LED auxiliary lighting, mounted to the cargo bed. It's also stylistically augmented with fender blares, Bowtie emblems, and rocker steps all done up in black to match the 17-inch alloys shod with Goodyear DuraTrac all-terrain tires. Chevy has also equipped this truck with an automatic locking rear diff, a transfer case shield, recovery hooks at the front, a spray-in bedliner, projector-beam headlamps, fog lamps, and all-weather floor mats. Chevy has also fitted this pickup with color-keyed door handles and mirror caps, upgraded exhaust and air intake, rubber floor liners, brushed metal interior trim, and an illuminated grille badge. Public reception will determine how many of these and other additional features will be considered for production.

Chevrolet introduced the new concept vehicle at the SEMA Show today, where it joined concept versions of the Silverado 1500 and HD models to demonstrate the depth and breadth of the brand's three-truck lineup. "The Colorado Z71 Trail Boss Edition is made for tackling the tough terrain required to get away from it all and this concept version does it with rugged style," said Sandor Piszar, director of Chevrolet Truck Marketing. "And whether it's the Colorado, Silverado 1500 or Silverado HD, there's a Chevy truck to take you where you want to go, regardless of whether there's a road leading there." The production 2016 Colorado Z71 Trail Boss is offered in extended and crew cab configurations, with a choice of a long or short cargo bed and available 4WD – as well as the all-new 2.8L Duramax turbo-diesel, which takes the maximum trailering rating up to 7,700 pounds.

1972 Dodge Challenger on an M1009 CUCV military frame is YES

The subject of this post is cause for celebration, not reason to ask "But why?" We don't know why this random Craigslist seller chose to marry the body of a 1972 Dodge Challenger with the frame and axles from a 1987 Chevrolet M1009 military vehicle. We're here to appreciate it, thanks to The Drive, and maybe spend some time after dinner considering whether to buy it. Now that we're on the same page, an owner in Tucson wants to rid his garage — or his Bullet Farm — of what appears to be an exceptionally well built conversion. Starting from the bottom, the M1009 CUCV, for Commercial Utility Cargo Vehicle or "Cuckvee," emerged from a program turning K5 Blazers into supply rigs that were meant to support hardcore hardware like the AM General Humvee. The M1009 got GM's 6.2-liter Detroit Diesel V8, a TH400 transmission, an NP-208 chain-driven transfer case, a 10-bolt rear axle and 3.08 gears. Produced from 1983 to 1987, they returned "less than desirable" results in the field and the military unloaded them. Not much of that remains for this build. The diesel got dropped, replaced by a 5.7-liter GM gasser with a four-barrel carb and long-tube headers, shifting though a 4L80E automatic transmission attached to a U.S. Shift Quick 1 transmission controller in the cabin. The seller doesn't mention output, but if it's a more recent Chevy 350 then it'll certainly provide a healthy bump over the maximum 160 horsepower from the diesel, especially running through a custom Flowmaster dual exhaust. An NP-205 two-speed transfer case switches between 2H, 4L, and 4H. The Dana 44 front and Dana 60 rear axles feature lockers and 3.52 gearing in back. Skyjacker Black Max provides the suspension to keep the 37-inch BFG KM2 on the pavement or the dirt. About 11,000 miles ago the owner rebuilt and upgraded the drivetrain, installing new accessories like a high-rise intake, four-core radiator, new alternator and Holley fuel pump. Losing the K5 body for an E-body Challenger cap means losing M1009 features like the rifle rack and gas can mounts. But you gain style, something real hard to find on a vehicle stout enough to back you up when you tell the crew, "I've been to hell and I'm going back." As part of that rebuild a few miles back, the minimalist interior got all new panels, dash and custom gauges, headliner, seats, and a Sony audio system with Alpine amps, a sub, and Kenwood speakers.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC
