Cars like Cadillac’s 556 HP, rear-drive, manual transmission-equipped CTS-V SportWagon are the kind of offering that enthusiasts lust after, even if a relative “value-price” of $70k-ish keeps it in aspirational territory. And by offering a CTS “Performance Edition” with the option of mating a six-speed manual to GM’s well-liked 3.6 liter V6, Cadillac gives enthusiasts an appealing opportunity to bask in some of the V’s reflected glory. But apparently not many enthusiasts are interested in pursuing this opportunity, as InsideLine reports that the manual transmission option will be dropped from the 2012 CTS 3.6.

What is luxury? In the American car market, that question doesn’t have an easy answer. Driver-focused performers like BMW’s 3-series sell well here, but so do feature-loaded versions of mass market sedans, like the Lexus ES. Blinged-out baroque still has its adherents, but as the Napa Valley hotel where the Cadillac CTS Coupe was launched proves, a more subtle, sophisticated version of luxury is gaining popularity as well, differentiated by the use of recycled materials and environmentally-friendly technologies. So where in this fragmented and changing category does the CTS Coupe belong?

Chrysler is sending out recall notices to owners of 25,000 Dodge Calibers and Jeeps. The reason: Accelerator pedals could become stuck and cause unintended acceleration, Chrysler said according to a report in Reuters. Sound familiar? Wait, there is more …

First developed by Holden in 2004, GM’s Zeta platform now underpins vehicles as diverse as the Statesman/Lumina/G8/Caprice sedans, and the Chevy Camaro. Originally designed for full-sized , rear-drive Australian sedans, Zeta was downsized as far as it could be for the Camaro, which reviewers largely view as overweight and rather too ungainly for true sportscar status. Accordingly, GM has been developing a new rear-drive platform known as “Alpha,” which will form the basis of GM’s performance and luxury RWD models for the considerable future. Last we heard about Alpha was last August, when Bob Lutz swore there was no development underway of the platform he compared to BMW’s 1-/3-series. According to Motor Trend, work on the Alpha platform has begun… but there are already signs of trouble.

I’m too young to remember the 1970s, but I have recollections of a Cadillac-based abomination known as the “ Castilian Fleetwood Estate Wagon.” Perhaps the recent success of Cadillac-based trucks made someone at the RenCen give the Cadillac Wagon a second look. Yet the CTS Sport Wagon isn’t a cobbled-up engineering afterthought, though it reeks of branding desperation: the American icon formerly known as the pinnacle of everything now goes for entry-level luxury success in a station wagon. And that’s why this mirage hailing from the days of Motorized Malaise has some ‘splaining to do.

Update: a portal to all of TTAC’s articles on the subject of Toyota gas pedals is here:

Toyota has sent instructions and the shims for the field fix of the recalled sticky CTS gas pedals to dealers as of today. We have obtained the instructions (pdf here) [Hat Tip: Roxer], shims, and carried out the fix on a new CTS pedal accordingly. Follow along as we carry out the fix, and how we arrived at our unhappy conclusion.

One of the lingering concerns over the Toyota recall is whether Toyota’s “precision steel” shim fix to the recalled CTS gas pedal assembly will be a reliable long-term solution. Our analysis indicates that these questions might be well-founded, and we’re not the only ones concerned about the viability of Toyota’s proposed fix. In an interview with Toyota’s Jim Lentz yesterday evening, NPR asked why Toyota was using a redesigned pedal for new production, but only offering the shim fix to existing customers. Lentz insisted that the repaired pedals would be as good as the redesigned pedal, that the costs of repair and replacement were about the same, and that the main reason Toyota was repairing rather than replacing recalled pedals was the desire to “get customers back on the road… as quickly as we possibly can.” That’s when NPR went for the jugular.

According to a PR Newswire release, a class action suit has been filed against Toyota and supplier CTS, alleging “inherent design defects,” specifically a “lack of failsafes” in Toyota’s ETCS-i (Electronic Throttle Control System-intelligent), in use since 2001. As in not the pedal assembly. A similar suit was filed in the US last November. Today, Toyota’s Jim Lentz was emphatic that electronics were not the issue with the ongoing recall, but shortly after the US suit was filed, Toyota quietly announced that an electronic brake override system would be installed on certain vehicles with automatic transmissions. Is that as good as an admission of guilt? You can bet the lawyers are already saying so. The full release is available after the jump.

Update: A portal to all of TTAC’s related articles on Toyota gas pedals is here:

Toyota has released their official “fix” for the sticky CTS-made gas pedals on the recalled models affected. From their graphic, it’s difficult to understand what parts are involved, and how they work. Thanks to our recent tear-down of the CTS pedal, we have the pictures and familiarity with the unit to explain it in detail.

In yesterday’s post , we offered a bounty for anyone to open up both the CTS (bottom) and Denso (top) Toyota gas pedal assemblies. No one took us up, and no one anywhere else has done it, so we took it upon ourselves . Here they are, both e-pedal assemblies taken apart and examined, in our quest to understand if and what the significant differences are, and how Toyota’s possible “shim” fix would work. On initial observation, it appears that the CTS may be perceived as being the more solidly engineered/built unit, in that the pedal pivots on a traditional and solid steel axle whose bearings are brass or bronze sleeves. The Denso’s whole pivot and bearing surfaces are relatively flimsy-feeling plastic. But that can be deceptive, and we’re not qualified to judge properly if it is indeed inferior or superior. So the question that goes beyond the analysis of these e-pedals is this: are these units really the full source of the problem, or are they scape goats for an electronics and/or software glitch? Pictures and tear down examination and analysis follows:

Update #2: It’s clear to me now that the CTS unit I took apart already had the side cover plates (sheet metal) removed before I examined it. One can see where they fit, and are obviously intended to protect the exposed axle pivot and bushing seen above and below:

(Update #3: Also see our follow-up stories on Toyota’s fix and our replication of the fix and its results)

Supplier CTS, who produced the gas pedals now under recall from Toyota, tells Automotive News [sub] that it “built parts to the automaker’s specifications and says it has no knowledge that its parts were responsible for any accidents or injuries.” Sources at CTS tell AN that although they are working on a fix with Toyota and that new pedals have been tested and are shipping to Toyota plants, “this is their recall.” That would seem to contradict the facts of the case, as Denso, Toyota’s gas pedal supplier for Japanese-built models, has not been involved in the recall. According to Inside Line, the issue with pedal return damping that has plagued CTS-supplied, US-built Toyotas has not turned up in Denso-produced gas pedals.

When someone pays tax, they generally like to think it’s going to towards something that will benefit society. Maybe it might be a repaired road? Or funding towards a crumbling school? I doubt they would want the money to go towards shifting a supposed CamCord killer or an alleged 3 series rival, but that’s what’s going to happen. BusinessWeek reports that executives at “New” General Motors are going to cut prices and rework adverts to boost flagging sales of the Chevrolet Malibu and the Cadillac CTS; two saloons considered critical to meeting Ed Whitacre’s target of a profitable 2010. That’s right, “New” GM are going to cut prices (A.K.A “Cash on hood”) to make more sales. Sound familiar?
