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 drops diesel engines for 2020 Chevy Equinox and GMC Terrain crossovers

GM is officially discontinuing the diesel engine in the Chevy Equinox and GMC Terrain for the 2020 model year. The 1.6-liter turbodiesel was always an oddball of an engine in the compact crossover segment, and now the experiment has come to an end. The Car Connection initially reported the news, and a GMC spokesperson, Stuart Fowle, confirmed it to us this morning.  “A huge majority of our Terrain customers have opted for one of our two gas engines," says Fowle. We canÂ’t say this eventuality comes as a massive surprise, as we saw news from couple of months ago that GM was dropping all-wheel drive from the diesel-powered cars for 2020. Low demand was cited as the reason for that cull, and itÂ’s the same for the little GM crossovers this time around, too. These vehicles were the only ones powered with a diesel engine in their class, but thatÂ’s going to be changing. Just as GM is going away from the diesel, Mazda is finally bringing its diesel to market in the CX-5. YouÂ’ll only be able to get that engine in the most expensive ($42,045) trim level, combined with all-wheel drive, though. The cheapest Equinox diesel starts at a comparably low $30,795. ThatÂ’s a $2,400 upcharge over the base 1.5-liter turbo four-cylinder, and the value is questionable. Mileage is better, but diesel fuel is more expensive. Towing capability didnÂ’t increase over the base engineÂ’s 1,500-pound capacity, but the extra torque around town was nice. As diesels go in the U.S., this one was rather rough and noisy, possibly contributing to some turning their noses up after a test drive. Perhaps another reason for its demise was that the much quicker 2.0-liter turbo Equinox was only $100 more than the diesel. This engine offered significantly better towing at 3,500 pounds, too. You can read all about what we thought of the diesel in our first drive review here, but the 2019 model year is the last one if you had it on your shortlist.

Recharge Wrap-up: Volt makes up third of Quebec Chevy dealerships sales, Tesla seeks Aussie talent

A Chevrolet dealership in Quebec has had the Volt make up 35 percent of its sales so far this year. Bourgeois Chevrolet in Rawdon, Quebec received recognition for the feat at the 2014 Electric Vehicle Conference, where it won the award for Leading Plug-in Hybrid Electric Vehicle Dealership. To sell that many, Bourgeois Chevrolet had to import used Volts from the US, and keeps about 50 units on the lot in various configurations. The conference also saw Park Avenue Nissan of Brossard, Quebec win the Leading Battery Electric Vehicle Dealership Award, and Loch Lomond Mitsubishi of Saint John, New Brunswick receive the award for Electric Vehicle Dealership Inspiration.

Ford, General Motors and Toyota have announced that they will shut down their Australian factories, leaving behind a lot of unused talent. Tesla recently held a "Recruiting Open House" in Melbourne for engineers to fill positions at its plant in Fremont, CA, where they will be paired with other Aussie engineers already on staff.

Valeo recently showed an electric turbo it plans to supply to an unnamed automaker at a fuel economy showcase event at the EPA's National Vehicle Emissions and Fuel Lab. Electric turbochargers have the advantage of greatly reduced lag when compared to exhaust-driven turbos. They also work well when paired with cylinder deactivation, providing a much-needed boost when driving on a grade, which can help reduce the need for cylinders to reactivate. Independence from the exhaust system also makes it easier to package the turbocharger wherever there is room. Read more from Navigant Research. US crude oil futures have dropped to their lowest in more than two years. Saudi Arabia cut oil costs for the US and raised them for Europe and Asia as the US has increased output. On November 3, US crude futures fell as much as 2.2 percent in New York. West Texas Intermediate closed at $78.78, the lowest since June 2012. Brent crude slipped $1.08 to $84.78 a barrel.
