TTAC has long seen stop-start systems (which turn off the engine at idle) as one of the many common-sense technologies that will continue to improve internal combustion engine efficiency at a relatively low cost. Outside of these digital pages, though, the systems have taken longer to gain awareness in the United States, resulting in the lagging adoption rate pictured in the chart above. Up to this point, we’ve assumed that this can largely be blamed on the EPA test’s unwillingness to acknowledge the urban-driving advantages of stop-start systems, pointing to Mazda’s protests on the matter as evidence that government intransigence was keeping the technology out of the market. But recently Mazda has announced that all of its vehicles will get stop-start as standard by 2015, and Ford has said that it will begin offering the technology on “some” four-cylinder models for the North American 2012 model-year… and the rest of Detroit isn’t far behind. So what’s the deal? The EPA hasn’t changed its test… why are stop-start systems finally starting to trickle over?

Thanks to new research obtained by TTAC from the cleantech investment fund Pacific Crest, we now have a better understanding of stop-start technology, and why we’re actually glad it’s taking so long for the systems to get here.

Every advertiser faces a basic choice at the outset of a campaign: come up with unique, relatable imagery for ads, or riff on an established cultural meme. Volkswagen went the latter route with its “Darth Vader” Super Bowl ad, achieving huge success: it was the most popular auto-related ad of the Super Bowl, and the Youtube version has received over 40 million views. The only problem with appropriating such popular imagery: you don’t enjoy unique rights to it, meaning you can be easily hoisted by your own petard. Which is exactly what’s happened here to Volkswagen. Greenpeace is angry that VW opposed a bid to bump the EU’s 2020 emissions goal from the agreed-upon 20% to 30% of 1990 levels (even though C02 emissions improved 3.7% last year and 5.1% in 2009, and average emissions are on track to hit the 130g/km 2015 goal ahead of schedule). As a result, they’ve turned VW’s hugely popular “Darth Vader” ad on its head, identifying the giant automaker with the evil Lord Vader, and encouraging fans to “join the rebellion.”

I’m planning a purchase this summer. The two cars I’m looking at most closely are the Mazda2 and the Scion xD. I noticed that the 2011 Mazda2s are spending an average of 109 days on the lot, and the 2010 xD is even worse at 239 days. Your February sales charts and March charts paint a similar picture. They’re both selling terribly, but I’m so far unable to find good deals on either, for different reasons.

In something of an ironic twist for an off-road brand, Jeep has had trouble figuring out which path to take lately. Jeep was late to the soft-roader party last decade, and got off to an “interesting” start when a focus group (allegedly) indicated the need for a Patriot to appeal to men and a Compass […]

From its very first paragraph, a recent New York Times article trolls hard for defenders of America’s car-centric culture:

While American cities are synchronizing green lights to improve traffic flow and offering apps to help drivers find parking, many European cities are doing the opposite: creating environments openly hostile to cars. The methods vary, but the mission is clear — to make car use expensive and just plain miserable enough to tilt drivers toward more environmentally friendly modes of transportation.

Does that not have your red American blood boiling? Stand by for some technocratic condescension from a Euro-crat

“In the United States, there has been much more of a tendency to adapt cities to accommodate driving,” said Peder Jensen, head of the Energy and Transport Group at the European Environment Agency. “Here there has been more movement to make cities more livable for people, to get cities relatively free of cars.”

Though the piece continues generally in this vein, the NYT has blessedly decided that there is “Room For Debate” on this issue, and has posted a number of diverging perspectives on it. Urban planning is a notoriously heated topic, accentuating the urban-rural divide as well as the central-planning-versus-absolute-freedom ideological divide, both of which are more pronounced in the US than in Europe. With this in mind, let’s make sure we approach this topic in a respectful, constructive manner. It’s a topic that will inevitably come up again in the future, so let’s take this opportunity to practice discussing it without resorting to ideological name-calling. [HT: David Holzman]

Our sharp-eyed, GM-obsessed buddies over at GMInsidenews.com captured this image from a video that appears to have disappeared from the GM.com website, and they’re pretty sure it shows a skin-off look at the forthcoming Cadillac ATS. Based on the troubled (think: 4,000 lbs)Alpha platform that will also underpin the next-gen CTS and Camaro, the ATS is likely to launch with four-cylinder engines in naturally-aspirated and turbocharged forms, with a possible twin-turbo V6 rumored for the “V” version. Unless, of course, GM has made the questionable decision to engineer the platform to take a small-block V8 (which actually would not be much harder to package than a twin-turbo V6). Meanwhile, the big news recently on the ATS front has been GM CEO Dan Akerson’s opinion that the ATS and XTS

are not going to blow the doors off, but they will be very competitive.

We can’t see any front or rear subframes, so rumors of a complex and “sub-optimal” multilink front suspension must remain rumors for now. Otherwise, the body seems to have some strong potential looks-wise. Let’s just hope the entire package is able to deliver something better than what the rumors are suggesting, otherwise GM will have squandered yet another opportunity to crack the lucrative 3-Series market.

With a new Viper being readied for a 2012 auto show debut ahead of a 2013 launch, Automotive News [sub]’s Rick Kranz has discovered something of an issue in the development process: suppliers don’t want in.

Ralph Gilles, who heads Chrysler Group’s design organization and SRT, the automaker’s performance group, says many suppliers said “thanks, but no thanks” when the automaker knocked on their doors.

“It has been tough to get low-volume suppliers,” Gilles says. “We have had a few hiccups here and there as we get suppliers. That type of fringe business has really dwindled. A lot of people are looking for big accounts now, but now that is behind us.”

Kranz blames low volume (2,103 units in its best year, 392 units last year) and supplier consolidation for the “hiccups.” But as it so happens, this has been a recurring problem for the Viper since day one…

How user-serviceable should a car be? Should special tools be required to perform basic tasks? If the car in question is a sporty car, should there be less effort on the manufacturer’s part to ensure serviceability (because it’s a “toy” and more likely to be owned by people with multiple cars) or more (because sporty cars tend to have longer in-service lifetimes and have a more self-service-oriented owner base)?

After performing most of the 30,000-miles service on my 2004 Boxster S “Anniversary Edition”, I believe I’ve become a little more passionate about my answers to the above questions.

When asked by thenational.ae if he preferred to drive his McLaren F1 or Mclaren-Mercedes SLR to work everyday, the man who designed both legendary hypercars, Gordon Murray demurs:

I wouldn’t say the SLR is quite an everyday car but I certainly like to drive it to work. But for me, despite all those cars and my single-seater Rocket [a car he privately designed], it’s the [eight year-old Smart Roadster] I’m most taken with. For one, it’s a great-looking car. It has a power roof, heated seats and air con, and it all weighs just 830kg. In fact, it’s got all you’d want from a car. It nips around corners and it’s fun to drive.

So, other than proving that Murray has exquisite taste (I’d kill you all for a Brabus Smart Roadster Coupe), what’s the point? That, having been there and done that in the world of high performance, Murray’s taking on a less obviously sexy but ultimately significant project that first occurred to him in a traffic jam back in 1993: the T.25 and T.27 city cars. We’ve written about Murray’s T.25 before, but the real news today is the release of specs for the T.27, an all-electric version of the tiny three-seater. And yes, it weighs 1,500 lbs on the nose (including batteries), and ekes 100 miles of range out of just 12 kWh. That beats the efficiency of competitors like the Smart EV (by 29%), the Mitsubishi iMiEV (by 36%) and MINI E (by 86%). So, how does it do it?

The Malaise Subaru Apocalypse is in full swing in Colorado, if we are to judge from the selection of old Leones in Denver junkyards these days. Yesterday, we saw this ’82 GL “Cyclops”, but that was just the beginning of the Subaru death toll in this yard. A few rows away, I found this brown GL wagon, a little rustier than the ’82 but still appearing to have plenty of life left in it. Is anyone restoring these things? (Read More…)

The battle over the Houston, Texas red light camera program returned to the legal spotlight Monday. A majority of voters agreed with Francis M. Kubosh and Randall Kubosh in November that the automated ticketing machines should be removed, but a federal judge intervened earlier this month and overturned the election (view ruling). The Kuboshes filed a reply brief with the US Court of Appeals for the Fifth Circuit Monday seeking to restore the result of the public vote.

Careful when transiting Nevada by car: Soon, there can be driverless cars on the roads of the desert state, legally. Nevada passed Bill 511 (full text here) that lays the framework for autonomous vehicles.

For instance, the bill authorizes the Nevada DMV to come up with rules for driverless cars. Just think of it: Will you need a driver’s license to operate a car that needs no driver? (Read More…)

Whereas speed cameras are plenty in Japan, the use of red light cameras has yet to catch on in the land of the rising sun. Instead of viewing red lights as revenue sources, Japan (which certainly could use the funds) is spending money in a big way to make red lights and stop signs safer. The Japanese National Police Agency is starting to roll out its Driving Safety Support System (DSSS) in Japan in July. Instead of waiting for someone to run a read light, and then dispatching a costly ticket, this system attempts to reduce the instances of red lights run. Toyota and other Japanese manufacturers are starting to integrate their cars into this system. (Read More…)
