TTAC reader (and Pontiac G8/Holden conversion owner) David Obelcz gives us his thoughts on the current situation in the world of crude oil – and how that will affect car enthusiasts.
Over the Thanksgiving holiday in the United States, Saudi Arabia blocked a proposed production cut by OPEC, sending oil prices plummeting around the world. As I write this the price of oil and gasoline futures are in collapse. West Texas Intermediate (WTI) futures are down over 10% to $66.15 a barrel on the near-month (January 2015) contract, Brent is at $70.15, and gasoline futures are down to $1.90.
TTAC commenter Buickman, better known as Jim Dollinger to friends, colleagues and loved ones, was on Autoline Detroit last week to present his plan to save General Motors. Rather than present it in the form of an article, we’re posting Jim’s Autoline segment for your perusal The video should start right at Jim’s segment, but if it doesn’t fast forward to the 42 minute mark. Let us know what you think of the plan.
TTAC reader Majda shares his tale of becoming a driver for ridesharing app Lyft.
Few car enthusiasts get paid to drive soused, singing young women around town. I do. The price was zip-tying a pink moustache onto the grille of my Mazda3.
TTAC reader Evan Reisner thinks that a small pickup is just the ticket for GM. But it’s not the one you may expect.
The prevailing wisdom on TTAC is that many Americans are interested in a compact pickup truck – but the same wisdom also suggests that such a truck would be bad for GM’s CAFE ratings. Market demand aside, CAFE is one of the reasons that Chrysler and Ford got out of the small truck game.
Yet few people know that The General has a product that can combine the best of both worlds. But they’ve chosen not to offer it in the USA.
TTAC reader and former auto journalist Michael Banovsky writes about the inexorable move towards autonomous cars
Autonomous cars are already here.
It doesn’t matter if you’re testing an actual Google Car or cruising the Keys in a Pagoda-roof 230 SL, CUVing the kids to Hot Yoga or signing “11” on a deserted road. Autonomous cars are here, the debate is done, so enjoy driving while you still can.
Let’s start with a story.
Reader Daniel Latini is a car guy and has a baby on the way. He’s looking for your advice on a new ride that can carry around his family.
My wife is one of those generally temperate souls who has a few firecrackers strewn about her personality. New challenges can spark a little friction in any couple, and something popped when we saw the ultrasound pictures of our still-developing first child.
Her current steed, a middle-aged Korean compact hatch, lost a lot of luster that day. I’m sure the B&B will pelt me with shop manuals for trading a car with less than 100,000 miles, but I think there are some sound reasons to consider an upgrade.
We’re young, clueless and enthusiastic – click the jump and join us as we begin the misadventure of finding our first family hauler!
A TTAC reader is an engineer with a major powertrain company, and offered his extremely detailed analysis of the ZF 9-speed. Consider this an AP level course in powertrain engineering.
Before we dive right in to the 9-speed gearbox, let’s take a quick refresher on the basics of gears. The simplest gear set consists of 2 parallel gears mounted on 2 parallel shafts. Shown in Fig.1 is a gear set with a 20 tooth drive gear on the right and a 30 tooth driven gear on the left. For this gear set the speed of the driven gear is 1.5 times lower than the drive gear, and assuming no frictional losses anywhere, the torque on the driven gear is 1.5 times higher. This gear set has a ratio of 1.5:1. This type of a gear set is usually not favorable for packaging since it requires 2 parallel shafts, and there are largest separating forces that push the 2 gears apart which means that the bearings supporting the shafts have significant radial loads on them, in addition to an axial load if the gears are helical.
TTAC reader Dean Trombetta is back, giving an insider’s look at a widely reported but mis-understood story involving automotive plastics.
Last week, Aston Martin announced the recall of more than 17,000 vehicles for defective throttle pedals. The term “counterfeit plastic”, was frequently mentioned in the story, and for those not in the plastics business, the term may seem confusing. We usually associate the term “counterfeit” with consumer goods, specifically luxury items like watches, handbags and women’s accessories. Despite being in the plastics industry, I wasn’t sure what initial reports were referencing. But further research has shed some more light on the matter, and there seem to be two possible scenarios at play here.
This week’s Ur-Turn comes from David Ruggles, a noted industry figure, prolific TTAC commenter and author of the Autos and Economics blog.
In my 44 years in the auto industry there have been a couple of continuing themes I have observed. First, there is never ending change. Second, consumers are uncomfortable with the negotiating process required when buying a vehicle. These days vendors to auto dealers are trying to sell dealers on the concept that “transparency” is the key to success in selling cars.
TTAC reader Dean Trombetta sent us an article on anti-freeze resistant nylon and its applications in the automotive world.
In early 2011, a class action lawsuit was filed against Porsche alleging that the company knowingly installed defective coolant pipes made of nylon into engines of Cayenne model SUV’s. Apparently, the pipes are very likely to fail prematurely resulting in serious engine damage. If the vehicle is out of warranty, customers end up spending big bucks to repair their engines and replace the coolant pipes. The replacement coolant pipes are made of aluminum. (Read More…)
