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.

Who sold the most heavy-duty pickups in 2012? PickupTrucks.com investigates

Domestic manufacturers enjoyed a good year for heavy-duty pickup sales in 2012. PickupTrucks.com has taken a close look at exactly how those sales broke down between each manufacturer and between three-quarter and one-ton pickups. Ford sold some 67,786 F-250 Super Duty models last year with the Chevrolet Silverado 2500 HD falling just behind at 56,359 units. The Ram 2500 HD came in third at 41,918, while the GMC Sierra 2500 HD earned itself fourth place with 27,616 deliveries. While Ford held onto the top spot in the one-ton market, Ram easily nailed down second place by selling more 3500 HD models last year than General Motors sold Silverado 3500 HD and Sierra 3500 HD trucks combined.
So, did GM manage to sell more trucks than Ford with its two brands? Very nearly. Ford sold a total of 119,338 heavy-duty pickups to GM's 111,555. Ram, meanwhile, moved a distant 77,583. But perhaps more interesting is the diesel take rate in this segment. PickupTrucks.com says 80 percent of all domestic one-ton trucks roll from the dealer lot with a turbo-diesel under the hood. Head over to the site for a closer look at the breakdown.

Watch this time-lapse build of the Chevy SS for NASCAR

There's only about a week left until we get our first look at the production version of the 2014 Chevrolet SS sedan, but Chevrolet NASCAR teams have been looking at the race version of the car all winter. Autoweek has posted a really neat time-lapse video showing just a portion of what it takes to build one of NASCAR's new Gen6 stock cars.
Though the video is quite brief, it does show almost the entire build process starting with just the car's nose, and it gives us a good look at how integral the template is to the final product. As a bonus, Hendrick Motorsports also provided some videos showing two of its teams performing pit stop tests over the winter. The second video shows some of the more detailed aspects of the racecar's rear end, including the stock-looking trunk cutout and a newly mandated rear bumper extension that will be used on super speedways like Daytona and Talladega.
