Mazda doesn’t want to get caught in a “what did you know and when did you know it” and has decided to put brake override systems into all models to be launched anywhere in the world from now on, reports The Nikkei [sub]. Read More >

Toyota and its contracted engineering auditing firm Exponent held a webcast today to refute the claims that Professor David Gilbert has leveled in an ABC report and recent congressional testimony. Gilbert claimed that he was able to induce sudden acceleration without triggering failsafe mode or an error code in Toyotas by hacking into a Toyota pedal. Toyota and Exponent’s central claims are that the conditions created in Gilbert’s test could not be replicated in real life and that similar tests produced identical results in competitor vehicles.

When it comes to mountains of data like the NHTSA vehicle complaint data base, one man’s junk is another man’s treasure(trove).  Yes, there are limitations. But the remarkable degree of similarity of the UA rate between most badge engineered cars, and GM’s consistently low UA ratings speak of statistical relevance to some of us. One of those is David Lapidus, (TTAC handle: David42), whose data diving and Excel skills vastly overshadow mine.

In the last data dive, I used numbers from Edmunds to come up with a UA complaint rate for 117 cars from MY 2005-2010, excluding the flurry of complaints filed with NHTSA after the Toyota mat recall 0f 9/29/09. But those are cumulative, over the five years. David has taken it to the next level, to the individual model year. We may come back to the whole list another time, but initially we decided to focus on the Toyota Camry, since its large volume of sales and UA complaints would inherently increase the statistical accuracy of the numbers. And although this data dive may not solve the UA puzzle, it does raise serious questions about the most recent recalls and the Congressional barbecue of Toyota. Read More >

Toyota has just started a live webcast intended to rebut some of the allegations made by Professor Gilbert, among others. Click here to watch the webcast, already in progress.

One of the arguments in favor of GM Chairman/CEO Ed Whitacre’s use of AT&T corporate jets is that “given the role he plays and the decisions that need to be made worldwide, you want this guy to be working 24/7.” But like so many of the “answers” we’re given about GM’s turnaround, this merely raises another question: besides learning such arcane auto-industry jargon as the term “segment,” what exactly is Ed Whitacre doing at GM? Thus far, the answer seems to be “firing executives,” as the last several months have seen a number of executive reshufflings at the RenCen. And though GM’s bailout left a number of GM lifers in positions they had mishandled prior to bankruptcy, the recent firings and re-orgs aren’t simply motivated by the desire to revitalize GM’s corporate culture. A look inside Whitacre’s reign of terror shows a more traditional GM impulse at play: the desire for quick spikes in volume.

Toyota has long insisted that the Lexus HS250h would be America’s luxury “dedicated hybrid” model, while the smaller CT200h would be a Europe-only model. That decision was an presumably based Lexus’s desire to match its US sales success in Europe by offering a unique model that was more attuned to European tastes, hence the CT’s trim, five-door-hatch packaging. But with Toyota and Lexus sales suddenly in trouble in the US, attracting “a whole new buyer to the Lexus brand,” as Lexus flacks put it to Automotive News [sub] suddenly took on a much higher priority. And so, the 1.8-liter Euro-hybrid will bring its “2.0-liter performance with class-leading CO2 emissions” to the US market beginning early next year. As a Euro-market model brought stateside to add youth-upscale appeal that its similarly-positioned US-market brand-mate is struggling to establish, the CT200h’s parallels with the forthcoming Buick Regal are intriguing. That Toyota is taking a page from GM’s product plan-thrashing playbook is just plain troubling.

The personal transportation choices of auto executives has always been an easy point of reference for members of the mainstream media looking for an easy story. From Alan Mulally’s Lexus to Akio Toyoda’s Davos Audi getaway, auto execs’ use of non-company vehicles is always good for a quick “gotcha” headline. But no story in this rich oeuvre has had quite the impact of Jet-Gate, the name given to the mini-scandal that erupted when the executives of Ford, Chrysler and GM arrived in Washington DC for bailout hearings in three separate private jets, prompting derisive comments from members of congress. The PR misstep has haunted Detroit ever since, inspiring federal rules barring bailed-out automakers from using executive jets, and making transportation choices for auto-related DC hearings a major priority for automaker PR: Toyota’s Jim Lentz clearly had the episode in mind when he arrived for recent hearings in a recalled and repaired Toyota Highlander. And thanks to a recent revelation about GM Chairman/CEO Ed Whitacre’s use of executive jets, furor over auto-exec transportation is clearly a long way from playing itself out.

Even since Landwind crash test, and the Brilliance crash test, the reputation of Chinese cars in Europe has been a little, shall we say, challenging. Watching the bonnet of a car crumble like Professor Gilbert’s theory on Toyota’s UA tofu does have its effect on prospective customers.

But none of this seems to worry BYD. Europe is their next target. Autocar reports that BYD, the maker of China’s biggest selling car, the F3, will be coming to Europe in 2011. Not with their bestselling F3, but with a pure electric E6. The car was introduced at the Geneva Motor Show. Read More >

Back from his hibachi-tour to the hill, and a trip to China, Akio Toyoda this afternoon paid his respects to Japan’s Transport Minister Seiji Maehara, to Economy Minister Masayuki Naoshima, and to the man himself, Prime Minister Yukio Hatoyama. And what a difference it was compared to the enhanced interrogation in Washington. Read More >

“What should I buy?” Well these days it really doesn’t matter as much as you would think. The marketplace is absolutely riddled with 300+ late models to choose from and most of them are perfectly fine daily drivers. A Toyota? A Buick? A Mitsubishi? For most folks it really doesn’t matter. I’m not kidding. Their footwear is going to have a bigger impact on their quality of life than the car they drive.

But even today’s automotive world has a few cars that will cost more money to maintain per capita than our national debt. I’m not kidding there either. Bad engines. Clunky transmissions. Electric Gremlins worthy of a Steven Spielberg Sequel. Not to mention safety recalls that could even make a Chinese bureaucrat nervous. So without further lawsuits or potential censorship issues from aspiring TTAC sponsors, here they are… Read More >

In the TTAC Pedal Series “Toyota Gas Pedal Fix Simulated: Friction Reduced, But By Too Much”, I anticipated that the crude shim fix for the recalled CTS “sticky pedals” would result in an uncomfortable pedal feel at the least and  quite possibly unsafe characteristics at worst. A quick refresher: a carefully controlled degree of friction (hysteresis) is essential in an e-pedal, otherwise smooth changes and maintaining steady states in throttle position become difficult if not impossible. I wrote: “Undoubtedly, Toyota’s intended degree of friction will be compromised by this fix, to one degree or another. And drivers may find the fix unpleasant or uncomfortable, also to some degree or another. Clearly, this fix is a band aid to fix the intrinsic limitations of this design.”

I’ve been counting the days until someone complained about the results of the pedal fix. Yesterday it came, from TTAC reader JAQUEBAUER:

My daughter took her 2009 Camry in to the dealer today for the Gas Pedal recall, and were very surprised and disjointedness with the “fix” that Toyota has chosen for this problem. We picked the car up, getting the keys and a copy of the repair order from the cashier. We were not told about any precautions to take or be aware of changes in the operation of the car. The Repair order indicated that the cars computer was reprogrammed, and some work was done on the gas pedal. I asked her to test drive the car in the dealers parking lot before she went home, to check for any problems.

There were 2 issues she found unacceptable, that I want to talk about here. Read More >

And while we are solidly in left brain mode, here the explanation of Toyota’s brake override. You can start on a steep hill, even brake with your left foot, says Toyota. Let their presser speak for itself: Read More >

This is left brain – right brain weekend. While the more image driven can submerge themselves in pictures of old car ads, the other faction can unleash their inner nerd with abandon. Yesterday, we covered how ABC had entered the grail of automotive disaster-fakery, previously populated by NBC and CBS. ABC’s smoking gun video had been torn to shreds.

Today, we turn our attention to the man who aided and abetted the tricksters: Associate professor David Gilbert of the renowned Southern Illinois University. His work has been inspected by Exponent, a research company hired by Toyota. Hired by Toyota? Well, that should discredit Exponent immediately. Not so fast.

Crash Sled thankfully has found a full copy of Exponent’s retort to Gilbert’s machinations. The report is hosted on the ABC website, so we can assume it passed ABC’s scrutiny, for what that may be worth. Let’s look at the report a little closer.

Warning: This discussion needs a basic understanding of electric circuitry. If that’s not your thing, then don’t waste you time reading further. We’ll leave you to Sunday’s pictures with the message that Gilbert is a charlatan extraordinaire, and that whoever put him on the stand to make a case against Toyota needs to have his or her head examined. However, should you own a 2010 Toyota Avalon, then you have slight cause for concern. Read More >

[Note: This piece first ran in May 2007. It seems particularly relevant again in light of the current Toyota unintended acceleration (UA) situation. But please note that the circumstance that caused the Audi UA may, or may not be very different, depending on the circumstances. In the early eighties, electronic gas pedals and complex engine controls and other interfaces such as with ABS/brakes were still on the horizon. Nevertheless, the rules of physics have not been repealed. And an unknown percentage of Toyota UA events undoubtedly are the result of pedal misapplication. Audi’s near collapse in the American market after this incident remains a painful lesson in the power of the media, the slowness of the NHTSA, and the critical PR choices manufacturers make in the wake of a crisis like this.

When I first heard about the Audi “sudden unintended acceleration” segment on CBS’s 60 Minutes in 1986, I knew instantly that they were blowing smoke. Literally. Read More >

Last week, Professor David W. Gilbert testified at a house hearing and said he had replicated the unintended sudden acceleration in Toyota’s vehicles. Toyota, and their testing lab Exponent tried Gilberts method and said he was right. “But Toyota said it also created the same response in vehicles made by competitors, which it said rendered Mr. Gilbert’s findings misleading,” writes the Washington Post.

In a statement, Toyota says: “The analysis of Professor’s Gilbert’s demonstration establishes that he has reengineered and rewired the signals from the accelerator pedal. This rewired circuit is highly unlikely to occur naturally and can only be contrived in a laboratory. There is no evidence to suggest that this highly unlikely scenario has ever occurred in the real world. As shown in the Exponent and Toyota evaluations, with such artificial modifications, similar results can be obtained in other vehicles. “ When Exponent applied Gilbert’s test to five models, including a Honda Accord and a BMW 325i, all five vehicles reacted similarly.
