- Northstar project manager Greg Prior drives cross-country in an STS-V
By John Heinricy
Director, GM High Performance Vehicle Operations
It’s just after sunrise in Germany’s Eifel region of dense forests and mountains. Myself, and a small crew of fellow engineers and technicians, are getting ready for a day on the Nordscliefe – the “North Course” of the famed Nurburgring track.
I settle inside the 2006 STS-V, a pre-production example of the model Cadillac will start selling later this fall. I tighten my helmet and belts, secure the HANS device, and make a last check of the radio and the track’s safety lights. A push of the ignition button brings the 4.4-liter Supercharged Northstar to life.
We recently learned that additional development from the engineering team has resulted in a final number of 469 horsepower, making STS-V the most powerful production Cadillac ever. From the moment the first test lap starts, the Northstar’s power and refinement is apparent.
We’ve been coming to the ’Ring regularly for a few years. Testing at the ‘Ring is special. I’ve had a lot of experience racing and testing cars, including more than 250 professional races. But there is nothing else like this place. The Nordschliefe spans 13 miles. The course includes more than 170 turns and more than 1000 feet of elevation change. This, combined with high speeds, places huge energy into the chassis. That’s why we’re here. There is very little room for error.
To perform well at speed, the dynamic behavior of the vehicle needs to be impeccable. Predictability, precision, response, balance, control . . . as well as confidence and even comfort. These are attributes we’re looking for to describe the experience of driving a well integrated car on the ‘Ring. All the vehicle systems must be engineered to work together in harmony. Driving quickly – safely -- shouldn’t be a stressful experience. It’s an experience to savor. When it’s right you’ll know it. It’s our job to make it right and we take it very seriously. While we do time some of our laps, this is not about racing. Lap times are just one of the huge files of data collected each lap, all used to develop this Cadillac to be the best it can be.
The first couple of minutes on the track include many cornering transitions in which hard braking and accelerating occur in quick succession. The STS-V steering is precise and predictable. Brakes are responsive and very powerful, inspiring a lot of confidence, which is important given that the fastest portions of the circuit are imminent. The first of many long, undulating and sweeping turns calls for prolonged acceleration. The Supercharged Northstar provides constant hard pulling, with a strong-sounding intake and exhaust with a hint of supercharger whine. This is punctuated by smooth transmission upshifts taking us well into triple digit speeds (mph, not kilometers!) Braking for the upcoming sharper turn is a non-event. The huge Brembos grip with quiet efficiency.
Huge elevation changes start coming at me in the next few minutes of the Nordschliefe. These are fast descending and ascending sections with swells that get the Cadillac nearly airborne. The control engineered into the shock, spring and stabilizer bars can really be appreciated as the car swallows up the worst conditions the Ring can throw at it. The engine and transmission must work together with the chassis so that shifts and power delivery are seamless during these periods in which the chassis is being heavily loaded and unloaded repeatedly. The STS-V handles this with balance and control. This is exactly what we’re looking for – systems in the powertrain and chassis working together.
At the conclusion of the lap, I know it’s a success before the team looks at our data. I’ve made it through safely, for one. Secondly, the STS-V was smooth and well composed. This speaks to integration. We’re pleased that we turn laps in roughly 8 min., 30 seconds. But, STS-V is not a race car or an exotic sports car like the Corvette Z06 we’ll drive later in the day. STS-V is a tremendously powerful and refined luxury sedan.
Taken nearly to its limits, we have verified that the car maintains its composure under extreme conditions. That translates to outstanding driving dynamics for the customer. Being engineers, we of course find some things we want to tweak when we get back home. But our clear conclusion is that our STS-V development has taken the already-excellent performance and luxury of this sedan to its full extent – which is exactly our mission with Cadillac’s V-Series.

Solstice Delivers

2006 Pontiac Solstice
By Bob Lutz
GM Vice Chairman
As I write this, I'm on an airplane, returning from Portland, Oregon, where a group of leading auto journalists got their first opportunity to drive, or should I say, wring out the Pontiac Solstice on some of the world's nicest mountain roads, including a closed-course, private mountain pass put in by the legendary Sam Hill (origin of the question "Where in the Sam Hill....?", testifying to the high-altitude remoteness of his chosen luxury residence).
Compared to earlier pre-production examples, these cars had the latest air induction system for vastly reduced induction noise, and a freer (but still legal) exhaust system, which produces a very pleasant sporting exhaust note and adds greatly to the character of the car.
While most professional journalist-evaluators hate the question, "So, what did you think?" (it is considered bad form for the host to ask this question, which puts the guest on the spot), in this case the reaction to the car was offered spontaneously: it was declared an overwhelmingly competent and desirable car by all, with special praise going to style, refinement, compliant ride, sharp steering, high grip, and neutral handling at outrageous cornering speeds, especially considering the almost-incredible price.
I do believe the car made the point we intended for it to make: the product development process at GM is back on track. We understand beauty, excellence, the best-in-class imperative, and value for money, and the organization has the will and the capability to deliver. I felt huge pride in the GM team that created this exceptional car, and optimism knowing it is but an early signal to the public, and a warning to our competitors, of more to come, as GM finally musters its enormous global talent pool and focuses it on winning products.
And, speaking of delivering, I am told that the First 1,000 Solstices are being built now in our Wilmington, Delaware, assembly plant and will be shipped the first week of August.
P.S. And here's the bitter orange marmalade recipe.

Transportation From a Different View
By Joe Katona
Director, Vehicle Architecture
General Motors Product Engineering

Joe and John Katona
This site speaks to GM’s products, but there hasn’t been much written about the products my family and I have had to start thinking about since April. That’s when my 17-year-old son, John, was in a car accident that left him paralyzed from the shoulders down with a severe spinal cord injury.
As an engineer, I’ve always been interested in and involved with how our cars and trucks work, but after my son’s accident I was thrown into a situation where I had to think differently about what my family needed for transportation. Our lives and needs had changed dramatically.
At Craig Hospital in Colorado, where my son is being treated, other families who learned I worked at GM had questions because their transportation needs had changed, too. I couldn’t answer many of the questions because I’d never been in position where I had to think about them. Parents at the hospital wanted to know:
--What products does GM offer for families dealing with mobility issues?
--What incentives does GM offer on mobility-equipped vehicles?
--How does one best compare product offerings and information in an unbiased way?
Nearly all of it was new to me. I knew that being a GM engineer gave me an advantage, but I still felt overwhelmed with the many aspects of dealing with disability, including those associated with mobility. It seems there are reams of information, but no way to evaluate how credible and accurate the information is. There are no reliable, third party resources for my family and others like ours – all facing these important decisions, which will affect how well we get around to shop, visit the doctor or see family and friends.
Fortunately, I was able to reach out to a team at GM working on products and services for people with special transportation needs. You can see much of their work at www.gmmobility.com. I am trying to get as much information as I can from GM’s mobility team, but they also want to learn from me and others facing similar family issues. They want to know what we think and what we need.
The GM Mobility team and I want to learn what has worked for you. Please post your thoughts and experiences. I'll do the same through periodic updates on this site as I learn more about GM’s offerings and gather additional information.
I look forward to hearing from you.
Here is the Katona family blog.

Q&A with Bob Lutz
The following is an interview with Bob Lutz that appears in the latest issue of Pontiac Performance magazine. (Visit www.myGMmagazine.com to sign up for a free one-year subscription.)
Q: You've often said that Pontiac is near to your heart. What is it about this brand and its image that draws you to it?
A: Its glorious history and its legitimate place in the GM brand lineup as an aggressive, performance-oriented brand, appealing to younger people who want a car or truck to be more than just transportation.
Q: Talk to us about Solstice and the impact you expect it to have on Pontiac's image. Will you buy one?
A: Let's start with the second question: Clearly, I've already placed an order for one, and very definitely intend to own a Solstice. I see Solstice as playing an image revitalization role for Pontiac, in that it's very hard to improve brand perceptions through advertising. The best way to change perceptions of a brand is through an iconic, breakthrough product like Solstice that captures everyone's attention. And I enjoy getting e-mails that say, "I never thought I would set foot in a Pontiac dealership but the Solstice is going to make me do it." That benefits the whole brand. In fact, Pontiac dealers are saying they're selling other cars because of people coming in for the Solstice, so it's already generating traffic.
Q: You were the catalyst that brought the GTO back, which was an exciting event for enthusiasts. But the reaction to the car has been mixed. How do you answer the critics?
A: Well, it was a fast program, and the only way we could get it was to adopt an existing Australian car. We never intended it to be a "retro" car; we intended it to be a modern interpretation of the GTO. It was intended to get some performance credibility back for Pontiac and get the brand back in the market with a rear-wheel-drive, great-handling, V8-powered car. It's done that. And I might add the '05 GTO is not disappointing at all. We're selling every one we can get, and we're selling many in markets where we have to break through again with Pontiac, like on the West Coast.
Q: What are your goals for GTO in the future?
A: The future is ill-defined at this point. But it is definitely safe to say Pontiac will not give up on rear-drive V8 performance.
Q: The public response to the GM FastLane blog has been very positive. Why did you think it was important to give customers a conduit to you on the Web?
A: I think blogs and the Internet have given us a way to have direct contact with a number of our customers and with auto enthusiasts and to get unfiltered feedback from the marketplace - both good and bad. In the past, that feedback either had to be formal research, or it was what you got as interpreted by your dealer organization. It was always filtered. And our dialogue with the customers was always either through advertising, which doesn't enjoy a very high trust or credibility factor, or it was through the media, who have their own agenda. Blogs permit a clear, unfiltered, direct person-to-person dialogue with customers, which is where we think the huge benefit lies.
Q: We've been reading a lot of cloudy forecasts for GM. Why should people be more optimistic about GM's future?
A: Because the best of our product onslaught is yet to come. The new design direction, as exemplified by the Solstice, the Saturn SKY, and the Saturn AURA has yet to really be demonstrated in cars and trucks across the board. But the HUMMER H3, the Chevy HHR, the Buick Lucerne, and others coming this year feature much bolder, more "breakthrough" design. They and our new lineup of utilities and crossovers will contribute to GM's turnaround. We do not intend to slow down in rolling out dramatic new products. On the contrary: we've increased our product spending for this year.
Q: You're obviously a strong advocate for performance, but what about styling - what do the designers have to do to attract new consumers to GM vehicles?
A: Well, that relates to the last question. We do realize that a purely research-driven and rationality-based product development process doesn't work. That's why we are actively encouraging our designers to be much bolder and we are learning to be a design-driven company again, one in which the designer originates trendsetting new concepts, as opposed to responding to a series of planning inputs. Good examples of this, cars that were inspired pieces of work by the designers, are ones like the Solstice and the Saturn SKY. And there are more to come like that. This is perhaps the element that's been absent from the mix, especially in GM North America, and it's one that we are aiming to fix.
Q: What do you think is the biggest change or development in the auto industry over the past 20 years?
A: It would have to be the advent and the growing strength of the Asian auto industry, which you could look at as three waves. The first big wave was Japanese. The second big wave, which is coming in now, is Korean. And the third big wave, which is yet to come in but we have inklings of it, is indigenous Chinese car companies exporting to the rest of the world. That development is a huge challenge to the established automotive companies of the West.
Q: What do you think will be the biggest change in the industry over the next 10 or 20 years?
A: Increasing globalization... to where country of origin will play an ever smaller role. Of course, there are obstacles to attaining that vision, such as national regulation and work force issues, but it really is, I think, an unstoppable phenomenon. The large companies will survive but they won't be national; they'll be producing cars around the globe, and shipping them to other markets as necessary.
Q: Is the SUV revolution starting to wind down? Are we going to see more cars and crossovers?
A: I think cars will stabilize ... I don't see them making a huge comeback. I think we may have seen the end of growth, but by no means will we see a decline, in large body-on-frame sport-utilities. But medium-size and smaller sport-utilities, both body-on-frame and body-frame integral, will continue to grow and rise in importance. Because of its two-box design, an SUV or a "crossover", regardless of all the criticism of SUVs, is simply a wonderfully rational body style.
Q: You made a comment in the past that many of the concept vehicles these days are like angry kitchen appliances. What did you think of the vehicles on this year's auto show circuit?
A: Actually I said that about seven or eight years ago, when there was a series of concepts at the Detroit show ... it seemed every company was trying to outdo the others in producing concepts that had a hard-edged, mechanical, Transformer-Robot look to them, which were obviously done by students of design - but not students of automotive design. Many of these themes were visually interesting, but not particularly effective or useful automotive designs. Most of the concepts this year have been excellent. GM's were focused more on the future of propulsion, in the form of the GM Sequel, and the GMC Graphyte, both of which I thought were very well done from a design standpoint. I also thought some of our competitors' concepts were very well executed, especially Chrysler and Jeep's.
Q: You have said fun is a lost art in the automotive business. Can you explain what you meant by that?
A: I said that in the context of performance, and performance vehicles and performance parts and the aftermarket and so forth. But in a larger sense, let's just say that I believe enjoying a car or truck used to be a guilt-free experience. More and more people are being swayed by sentiments of social guilt and environmental awareness into not admitting to themselves that motor vehicles that are dynamically excellent and have a good driver-machine relationship are one of life's greatest pleasures.
Q: Can you tell us something about Bob Lutz that people may be surprised to hear?
A: Well, people probably don't realize that I like to cook. I'm very fond of animals - I'm actively engaged with the Michigan Humane Society. I'm also probably one of the world's greatest amateur producers of bitter orange marmalade.
Q: What kinds of planes are you flying these days?
A: I'm flying a Czech-built L39 Albatros 1S, which was a Soviet Bloc advanced fighter trainer and attack aircraft. And since last summer I own a former German Air Force Alpha jet, a swept-wing fighter attack aircraft, almost new, and with twice the power-to-weight ratio of the Albatros. That's a very exciting airplane to fly. And I still fly my McDonnell-Douglas MD 500 helicopter, for commuting and getting to the military planes.
Q: Let's say GM is enjoying record sales in three years and the country is still facing some tough challenges. If somebody begins a "Bob Lutz for President" campaign, would you be interested? If you started a third party, what would you call it?
A: First of all, being more on the conservative side of the political spectrum, I doubt that I would feel the need to form a third party. But the remote possibility that someone would see me as qualified for that particular political office would be immediately nullified by the fact that I was born in Switzerland. Therefore the question is purely hypothetical and requires no further answer (laughs).
Q: I understand you're chairman of the New Common School Foundation... are you particularly interested in education?
A: Yes, because I think it's a very depressing fact that we have one of the worst K-12 school systems in the world. We are constantly lowering the bar to make it easier for everybody to step over. It's no longer a meritocracy. We are falling farther and farther behind other nations like China, Korea, India, and Japan in what we actually successfully teach our kids, especially in the area of math and science. I'm a member of the board of the Center for Education Reform. I'm actively engaged in the New Common School Foundation, which is focused on trying to improve the K-12 education system in Detroit. I think that we don't talk about it enough, but the quality of education is one of the greatest factors helping to reduce America's competitiveness versus the rest of the world. This comes at a very bad time, as the challenge from better educated societies is becoming greater.
