Looking back at the Citation IV concept that likely shaped the GM EV1

Those who forget history are condemned to repeat it. We're not sure how that applies to the GM EV1, but we'd still like to share something from Autoline Daily, an online automotive new show with our friend John McElroy. He's been covering the business for decades now and recently found something interesting: pictures of the 1984 Chevrolet Citation IV concept, seen above. Displayed half a decade before the first electric concept that would become the EV1 (inset), McElroy says it's now clear that the elegant, aerodynamic EV1 took a lot of styling cues from the Citation IV, which was developed in part thanks to GM's new-at-the-time Aerodynamics Laboratory. We agree with him that the spats over the rear wheels, the flush glass, and the covered headlights all bear a certain kind of similarity between the two cars. That the colors almost match is a nice coincidence. The Impact (the concept version of the EV1) looked "frumpier," McElroy says, because it wasn't as long as the Citation. You can read a lot more about the Citation IV here and check out McElroy's thoughts in the video below. Find the Citation starting at around 3:45. This content is hosted by a third party.

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.

NHTSA upgrades probe into 1.7 million GM vehicles over wiper failures

WASHINGTON — The U.S. National Highway Traffic Safety Administration (NHTSA) said Tuesday it is upgrading an investigation into 1.7 million General Motors vehicles for windshield wiper failures. The auto safety agency opened the probe in November 2018 to see if GM needed to expand a 2016 recall of 2013 model year Chevrolet Equinox and GMC Terrain SUVs to cover additional vehicles. The engineering analysis probe covers 2010-2012 and 2014-2016 Equinox and Terrain vehicles. NHTSA could demand a recall after it completes the probe. NHTSA said it has reviewed 1,900 complaints and reports related to the issue in the 1.7 million vehicles. NHTSA said it has seen elevated failure rates in the 1.7 million vehicles, even though GM said the recalled vehicles have "double the warranty rate and five times the complaint rate." GM said it will "fully cooperate to support their investigation. We do not believe these windshield washer systems are defective." The wiper failures that prompted the 2016 recall were attributed to water and debris intrusion into the windshield wiper assembly ball joints, leading to excessive wear and eventual detachment of the ball joint. GM said it was installing an improved windshield wiper motor and transmission assembly and relocating a drain hole at the base of the windshield. Related Video:
