GM Reinvents the Data Center for Safety, Service

May 14th, 2013
General Motors Co. says a new supercomputing data center and a fledgling shift to bring software development in-house should help it limit the size of future safety recalls.

The Detroit automaker, which formally opened the giant data storage center in suburban Warren, Michigan, on Monday, said the changes are examples of how it is moving faster to cut costs and serve its customers better by bringing more computer technology inside the company.

In the past, GM's regional operations tracked problems by themselves, sometimes without communicating with other regions, even though many of its cars are now sold worldwide. Engineers in one region would check a problem part, but it wasn't studied worldwide, at least not at the early stages.

Now, with new software developed by GM's so-called innovation centers and the data storage, problems are spotted quickly when they crop up across the globe, and they're assigned to the right engineer who can work with parts makers to fix the problem faster, said Randy Mott, the company's chief information officer.

"You'd hope that if there is a problem with a set of components, that you understand which components were potentially susceptible and you would expect your recalls to be smaller," Mott said. "You identify it earlier and you certainly limit it to only the ones affected by whatever the problem was."

GM, which typically sells more than 9 million vehicles worldwide each year, makes cars and trucks in 30 different countries. Many of its parts are common worldwide, so if there is a recall, it can be large and costly. When problems are spotted and fixed early, the size and cost can be held down, Mott said.

GM also said Monday that during the next two years, the company will close 23 data centers worldwide and consolidate them into its two new Michigan facilities. GM says...

Tesla questions if Chevy is first OEM building electric vehicle motors in US?

April 18th, 2013

Filed under: EV/Plug-in, Manufacturing/Plants, Chevrolet, GM, Tesla Motors, AutoblogGreen Exclusive



Astute readers and Tesla Motors took issue with a line from a General Motors press release yesterday that claimed the start of electric motor production for the Chevy Spark EV made GM the "first domestic automaker to build electric motors and drive units in United States." The question was whether or not Tesla, which builds the Model S in California, isn't already doing exactly that.

So we asked GM, which told AutoblogGreen that, "from our understanding Tesla does not 'wind' their own motors. 'Wind' is a verb that has a broad meaning synonymous with 'build' since the winding processes are the most capital- and process-intensive part of motor making, whether it is round wire (like theirs) or square wire like ours ('winding' for us means all the wire forming, wire insertion, twist, and welding are done at the same facility)."

In response, Tesla told AutoblogGreen: "We manufacture all parts of Model S motors here at the factory in Fremont, California. We have a winding line at the factory where we wind our own stators off of spools. We also manufacture the rotors and other components to the unit."

This all might be a bit of a semantic disagreement, but it is nice to see automakers fighting over the rights to say they were first in this particular aspect of electric vehicle manufacturing. It also makes us smile that the two companies involved both have "Motors" in their names, so maybe it's a point of pride. Now, if anyone wants to look into the history books and see how EV motors were made in the early 20th Century, we assume neither GM and Tesla could lay claim to being "first."

Q&A: Larry Nitz says GM “committed to electrification as a long-term journey”

March 12th, 2013

2012 Buick Regal eAssist

larry nitzAnyone who still doesn't believe that General Motors is serious about advanced technology in general, and vehicle electrification in particular, hasn't yet learned that post-bankruptcy GM is a very different company run by different people with a different set of priorities, most of which we would all applaud. One clear sign of this was the company's offering of a long list of key executives, including top technology leaders, for media interviews during January's Detroit Auto Show.

"I hope that we can look back at the Volt in 20 years as the inflection point where we started this journey."

While it's typical for automakers to put sales, marketing and (sometimes) design execs out there, if anyone else sent its top technology types out for media grilling at Detroit this year, I was unaware of it. And that is why I had the opportunity to interview both GM chief technology officer John Lauckner and global electrification director Larry Nitz. I began by asking Nitz about the cost vs. benefit of GM's mild-hybrid eAssist system standard on the mid-size Buick Regal and available on the Buick LaCrosse and Chevy Malibu.

Q&A: John Lauckner, General Motors chief technology officer

February 25th, 2013

Filed under: EV/Plug-in, Hybrid, Cadillac, Chevrolet, GM, AutoblogGreen Exclusive, At Witz End

2011 cadillac elr concept

john lauckner gmJohn Lauckner, one of the masterminds behind General Motors' breakthrough Chevrolet Volt EREV, has a full bag of big responsibilities these days that he calls the "technology trifecta." First, he is GM's chief technology officer. Second, he's R&D vice president. Third, as if those two jobs were not enough, he's president of GM Ventures, the company's venture capital subsidiary. "Basically," he says, "I'm deeply involved in technology."

I caught up with him for a brief chat at the Detroit North American International Auto Show in January and started with the same big question I've asked a lot of industry executives lately:

ABG: How will GM, or any full-line manufacturer, meet future Corporate Average Fuel Economy (CAFE) mandates, and California's ZEV mandate? You will be required to sell increasing numbers of zero-emission EVs and other electrified vehicles regardless of consumer demand for them?

JL: We're going to have to schedule some invention. If you look at the technology we're working with today, you have one view of what's possible. But the technology is rapidly changing, so we focus on five areas where we think important breakthroughs will likely occur:
  • One, automotive clean tech and propulsion-related technologies. That means batteries. motors, power electronics, emissions control devices and fuel economy technologies.
  • Two, connected vehicles and infotainment, where information and entertainment intersect.
  • Three, advanced materials - lightweight, eco-friendly and space-change materials, and forming technologies - the kinds of materials that cars and trucks of the future will be made of.
  • Four, sensors, processors, and memory. There is a lot of capability that more advanced sensors, processors and memory will let us unlock.
  • And five, manufacturing-related technologies.

"Within the fuel-economy regulations, there is a "check-up" in 2017."

Those are not the only areas where we will see new technology, but those are the ones where we believe that having a competitive advantage will probably drive longer-term and more sustainable benefits. Also, within the fuel-economy regulations, there is a "check-up" in 2017, where we will see where we are and figure out what that means for the regulations in place for beyond that time.

Killing Tesla Slowly: Horse vs. Gas vs. Electric and 1 Foolish CEO

February 18th, 2013
I watched in horror last week as Tesla's CEO Elon Musk attempted to turn a New York Times reporter into the next Ralph Nader and kill his company. It brought back memories of the Chevrolet Corvair that died as a result of GM's decision to fight what turned out to be false allegations instead of just making the car better. Sadly, even though they made the improvements, folks walked away from the car because they believed it to be unsafe. Technology transitions are painful, and moving from horses to cars in the first place wasn't easy either.

Why GM’s 2.0-liter diesel is cleaner in America’s Cruze than it is in Europe

February 8th, 2013

Filed under: Diesel, Chevrolet, AutoblogGreen Exclusive, Chicago Auto Show

Chevrolet Cruze 2.0 Turbo Diesel Engine

The 2014 Chevrolet Cruze will have three different engine options soon, including the new 2.0-liter diesel powerplant that is debuting here at the Chicago Auto Show. The other powertrain choices include the made-in-Toledo 1.4 turbo gas engine used in the Eco and upper trim models and the 1.8-liter gas engine (made in Toluca, Mexico; it is also built elsewhere for other vehicles). The diesel is made in Kaiserslautern, Germany. In short, this is an example of GM's global network, and the oil-burner is a long-term player in the game: the basic architecture of this engine has been sold since 1985. GM sold over a half-million diesel-powered cars around the world in the last year, including 33,000 Cruze diesels. In Europe, 40-percent of Cruze sales are diesel. The engine is currently used in a number of General Motors vehicles in Europe, including Zafira, Astra and Insignia models from Opel.

Well, almost. Mike Siegrist, chief engineer behind the US engine, tells AutoblogGreen that Chevrolet engineers in the US worked with GM's team in Torino, Italy to adapt the powerplant for GM's first US diesel passenger car since the 1986 Chevette. To do this, the team tinkered with four main aspects: emissions, diagnostics, environmental conditions (that is, how hot or cold it is outside) and altitude. Siegrist notes the US has higher paved roads - Mount Evans in Colorado, for example - than Europe does, and it also has stricter emissions regulations, all of which necessitated the changes.

Thus, the US Cruze TD has a new intake manifold and throttle body system and an increased capacity exhaust gas recirculation (EGR) cooler that offers better NOx control, Siegrist said. A common rail piezo injection system running at 1,600 bar (the European engine runs at 2,000 bar) offers "really, really good fuel control," Siegrist says. To start in colder conditions, the US diesel engine has ceramic glow plugs while the Europeans get metal glow plugs. There is also an engine oil heater that can be plugged in if you're trying to start the Cruze in frostbite conditions.

With all of these changes, the US 2.0 turbodiesel engine actually ends up being cleaner than the European model. Siegrist wouldn't venture a guess as to how much cleaner, exactly, but he did say it meets the stricter US standards and that, "the margin's bigger than what you think." So, for all those times when we wished we could taste the forbidden fruit of a European powertrain, this is a chance for America to get the better - or at least cleaner - end of the bargain. Unfortunately, tuning for US emissions and fuel also means we get less power. The estimated power output of the 2.0-liter diesel in the US is 148 horsepower, but its European counterpart enjoys 163. The price of progress.

If you’re a fan of the Chevy Volt plug-in hybrid, but have wanted a bit more style, General Motors might have something for you. Next month GM is going to unveil the 2014 Cadillac ELR extended-range electric vehicle, which shares its electric drivetrain with the Volt, but is wrapped in a much sexier exterior. We’re just under a month away from its official debut at the 2013 Detroit Auto Show, but GM has released a teaser photo of the new electric luxury coupe.

The 2014 Cadillac ELR will borrow its design heavily from the Cadillac Converj concept. From this single teaser photo we can tell that the production version will retain the concept’s side profile, but we will have to wait until next month to see what has changed. GM hasn’t released any other details about the 2014 ELR, other than stating that it will enter production by the end of 2013 and be built at GM’s Detroit-Hamtramck plant.

“The ELR will be in a class by itself, further proof of our commitment to electric vehicles and advanced technology,” General Motors North America President Mark Reuss said in a keynote address at the SAE Convergence Conference in Detroit. “People will instantly recognize it as a Cadillac by its distinctive, signature look and true-to-concept exterior design.”

The 2014 Cadillac ELR will have its world debut on January 15th.
