Plug In 2014: VIA makes the case for 'free' plug-in hybrid work vans, trucks

If you're a fleet manager who's been waiting anxiously for the chance to buy a plug-in hybrid van from Via Motors, your wait is almost over. If you work for the right fleet, anyway. David West, the chief marketing efficer for VIA Motors, took AutoblogGreen for a ride around the San Jose Convention Center in a Via van sporting an Electric Blue paint job as part of the Plug In 2014 Conference this week and gave us an update on how things are coming along. The big news is that the Via PHEV van production is going to start by the end of September. Via can currently build two vans an hour at its production plant in Mexico, or about 16 a day and could easily double that. "That would get us to 20,000 a year with two full lines running," West said. "We have the capacity." "There is no way gas can compete with electric." – David West, Via Motors But they can't sell that many quite yet. By the end of December, around 350 Vans will be made, mostly for a $20-million program from the Department of Energy (DOE) and the South Coast Air Quality Management District that will see the vehicles used by fleets that will report energy data to the Idaho National Lab. Via is also finishing up CARB certification for both the van and the company's plug-in hybrid pick-up truck. About 50 percent of Via's technology in the truck will not need to be tested again, since it's the same as what's in the van, but things like crash tests will need to be done twice. Despite the progress, this is not where Via hoped it would be today. The bankruptcy of battery supplier A123, "took about a year off our timeline," West said. "It's been getting a little slow getting it to market, there have been some challenges, particuarly since we had the country's worst recession right in the middle of this wrap up, but it's inevitable in my mind. There is no way gas can compete with electric." Maybe that's why FedEx has expressed an interest in buying around 5,000 units, West said. FedEx already has some pilot vehicles, just like Verizon does, and PG&E wants to replace all of their gas trucks with electric vehicles, which would be another 3,000 sales, he said. Besides the fuel savings, vehicles like these, with easy on-site power generation, could also work wonders in post-disaster situations, he said, since they could replace the need for generators.

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.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
