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.

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

Chevrolet Malibu could last until 2024 before joining the dodo

Automotive News pieced together all available intel on the Chevrolet and GMC lineups, trying to ascertain how much life each model might have left. Concerning the Chevrolet Malibu, the answer is not too much, and the historic nameplate's final years don't look like the glory kind. After a major overhaul in 2016 boosted sales for the ninth-generation sedan to 227,881 units, the 2018 sales fell to 144,542, and this year's are down almost 15% through the end of June. The Malibu is one of two Chevrolet sedans still breathing - the other being the Impala for now - but only for about five more years. AN says there'll likely be a refresh in 2022, followed by a visit from the Reaper in 2024. After that, it could be "indirectly replaced" by an electric vehicle, one of the 23 EVs that GM is working on for 2023.     The Impala will meet the ax earlier despite a recent stay of execution. Production is still set to close in January 2020. In the entire GM stable, Cadillac might soon be the only marque with sedans. The Buick LaCrosse has a date with death, and Groupe PSA won't supply Opels-as-Regals forever.  The Sonic hatchback should say goodbye at the end of 2020, a year before the seemingly eternal Spark is thought to die. Two years after that, according to one report, the Camaro will go back into cold storage, perhaps forever, and AN says an "expected redesign of the car in 2021 was reportedly canceled." Finally, let's give one final shout-out to the Chevrolet Cruze, a global nameplate, which in the United States alone outsells the Malibu, outsold the Camaro by a factor of three last year, and absolutely trounces the Impala, Sonic, and Spark. Even that couldn't get a stay of execution. In more uplifting news, everything's happening on the crossover and truck side in the next few years. The Chevy Bolt is due for a refresh next year, even though it has "become more important for self-driving ride-hailing fleets that GM Cruise plans to operate than for consumers." In 2021, the Bolt-based crossover should bow, first in China, then here. It's said to look like "a mix of the Bolt and Trax" in spy shots. Still waiting for a green light: a possible subcompact GMC crossover called Granite that might make it to market by 2023. The full-sized SUV triplets Tahoe, Suburban, and Yukon could show their new faces in 2020. The Silverado might get an updated interior in 2020 or 2021, while the Colorado and Canyon mid-sized pickups won't get attention until perhaps 2023.
