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.
Abraham Drimmer writes about moving from South Florida to Michigan in his Miata
“You need to sell your car”, my father told me, when I informed him of my imminent departure. I got the call in mid-October, I’d be leaving Miami for Ann Arbor on short notice. “That thing is going to be absolutely worthless in the snow”.
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.
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 >
This review comes from reader Nicholas Naylor, who rented a Seat Altea XL for a recent trip to Spain.
My wife and I attended a wedding in southern Spain recently, along with another couple who are close friends of ours. We’re all taller than average, and being that we’re attending a wedding, the luggage load was heavy. So my idea of renting something small and Euro chic was out of the question; it had to be a wagon. Enter the Seat Altea XL.
Today’s edition of Ur-Turn comes from Brian Driggs, a long-time TTAC reader, Mitsubishi fan and published of Gearbox Magazine, a digital enthusiast publication that we highly recommend.
As a North American Mitsubishi enthusiast, I often find the dismissive comments about the brand disappointing. While the US might be the second largest market on the planet (second to China, I suspect), it’s far from being the only market. I believe Mitsubishi is diversified enough they can afford to be more proactive with regard to automotive trends. News of the Renault-Nissan-Mitsubishi partnership only supports that belief.
