LG Chem's troubled Chevy Volt battery plant hiring once again

The Michigan battery plant known for paying its workers to do nothing has turned things around and is now hiring more workers, specifically to do something. South Korea-based LG Chem, which runs the factory to supply the Chevrolet Volt extended-range plug-in vehicle with its lithium-ion batteries, held a job fair recently to bring on 40 new employees in order to meet higher battery demand, according to WZZM, the ABC affiliate for Grand Rapids, MI. The LG Chem factory is in Holland, MI, about 30 miles west of Grand Rapids, and it made its first batteries last year. Prior to that, though, the factory gained notoriety after a US Department of Energy (DOE) probe found that workers there were getting paid to do, well, nothing. That's because demand for the battery packs was so low that it cost less for the plant to sit idle. The DOE was conducting the probe because of its financial grant to LG Chem. But that was then and today is today. LG Chem is looking to ramp up production in advance of the second-generation Volt. That 2016 model-year version is said to have a longer all-electric range and better performance and will ride on a new chassis, but few official details have surfaced. We will know more when we get our first look at the car at the Detroit Auto Show in January.

2019 Toyota Corolla vs. compact hatchbacks: How they compare

So you've read what we thought about the 2019 Toyota Corolla Hatchback. Oh, you didn't? Well, click to your left, we'll still be here. Just made some coffee, we're good for a while. Welcome back! Wasn't that riveting? The blue paint sure is bright, eh? Well, now you must be wondering how that new 2019 Corolla stacks up with all the other hatchbacks. And, despite long thinking that hatchbacks were doomed, there are actually quite a lot of them these days. So many, in fact, that we couldn't fit them all in our space-limited comparison chart. So, with apologies to the Hyundai Elantra GT, Kia Forte and the dead-man-walking Ford Focus, these were the cars we chose based on sales and competitiveness: the Honda Civic Hatchback, Mazda3 5-Door, Volkswagen Golf, Chevrolet Cruze and Subaru Impreza. We also included the outgoing Corolla iM for reference. If you think we've left something of interest out, you can always create your own comparison. Performance and fuel economy There is but one king here, and its name is Civic. While the sedan and coupe come with a naturally aspirated 2.0-liter 158-horsepower four-cylinder that's less potent than the Corolla's, the hatchback comes standard with the 1.5-liter turbo that aces the segment in terms of both acceleration and fuel economy. The Golf's acceleration should be comparable, but as you can see, it trails on fuel economy (still not bad, though). The new Corolla ends up being better than the rest with its new 168-hp four-cylinder paired to novel transmissions: a six-speed manual with rev-matched downshifting (!) and a CVT that mimics the actions of a 10-speed automatic. The Corolla does weigh more than everything else, though, so that could hamper its acceleration. Fuel economy data also wasn't announced, but Toyota indicated it would be a bit better than the old Corolla iM. Something akin to the 2.0-liter Mazda 3's numbers seems likely. As for the Mazda, its top two trim levels actually come standard with its bigger engine. In any event, despite its ample power, testing has often showed that the Civic is still the quicker car from 0 to 60 mph. And finally, let's not leave out the two on the end. The Subaru is the only car in the segment that offers all-wheel drive (the Focus RS and Golf R don't count), but is also the segment weakling now that the Corolla iM has been discontinued.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
