When Will Detroit’s Auto Engineers Start Getting it Right?
Every day it seems there are new headlines about problems plaguing US auto manufacturers. Plunging stock prices. Layoffs. Cash burn rate. Impact of high fuel prices and global climate change. This isn’t all new, of course. Much of it a replay from the past 40 years when we first experienced explosions in oil prices and financial problems in Detroit, such as a possible bankruptcy at Chrysler.
I’m a huge fan of the US auto industry. I’m one of the last people on my street who still buys American cars (Pontiac). But I’m extremely concerned. And given what’s been going on, I am surprised at the engineering priorities in Detroit. I had the privilege last week of serving as a judge for the annual Society of Plastics Engineers Automotive Innovation competition. Unlike some design competitions, this one is a very big deal, and has been around a long time. Top engineering managers (mostly from the Detroit area) show what they consider to be their most important plastic designs in new production models. Winners are announced at a huge banquet (Nov. 20 this year) and the top brass show up because of the high quality of the SPE competition. It’s truly the Oscars for automotive plastics.
I didn’t get a sense of the urgency in Detroit as I listened to this year’s presentations. It seemed like business as usual.
For starters, there were only two finalists in the environmental category. In contrast, “body interior” had five. Ford has begun an impressive campaign to replace a small percentage (5 to 12) of oil-based polyols in foams with a soy-based alternate. GM is using recycled content in an air inlet panel in the Chevy Trailblazer, diverting 445,000 pounds of plastic from landfills. Is this all the better we can do? What about some efforts to use blends of bioplastics to reduce our carbon footprint? What about game-changing efforts to reduce weight?
The bigger issue, for the immediate moment, is economic. There were several entries that reduce weight and boost performance. After all, that’s been the name of the game for plastic since its dramatic arrival as a body material in the 1954 Corvette. One of the impressive entries was an injection molded oil pan module that integrates an oil deflector and baffles, cutting cost and weight. Awesome. But this design concept from DuPont dates back at least 20 years, and it is just now debutting on production cars. Adding insult to injury, the nylon oil pan is a feature on the 2008 Daimler C Class four-cylinder diesel, not an American car.
A handful of the entries that reached the final judging stage point to where American engineering executives continue to put an inordinate amount of attention: high-end flourishes instead of economy and fuel savings. The most outrageous example is the “first integrated floor console and compressor refrigerator with performance exceeding home refrigerators by 50 percent.” I’m not making this up. It’s a $760 option on the 2009 Ford Flex, and is planned for future Ford vehicles.
Maybe I’m just getting old. I also don’t like TVs in cars or people who talk on their cell phones while they drive. There are signs of change. GM is literally staking its future on the electric Chevy Volt. I hope the engineering priorities at Ford and Chrysler are changing too. I just hope we still have the time to get it right.

Remember the plastic intake manifolds and all the trouble GM has had with leaks and Ford with cracking.
Now go to Wards engine listing, and look at Toyota, last year not 1 single plastic intake.
I expect the same results for plastic oil pan.
If it has in integrated lifetime filter, even worse.
I admit I am an atypical consumer, since I am an engineer it is to be expected. I expect over 200K miles from all my cars, and I drive domestic GM. Most make it easily with minimum troubles, exception was the Buick with plastic intake. At least after the recall, I got my expensive repair money back.

When cost reduction overides common sense, which is more common in USA mis-managed companies, we have disasters.

Remember the exploding Pinto\’s that followed after penney pinching Executives took the novel plastic liner out of the gas tank to save a few bucks? They are still in charge.
An industrial chemist commented:
They can\’t. Americans do not want to buy cars from American carmakers. The don\’t trust them, their executives, or their unions. The only possibility, and it will still take time, is to pretty much copy the bestselling foreign models, adding the American nameplate, and invest in the future with \”free\” auto services, including tires and brakes. There\’s really no magic, though. Put real effort and money into a car that shows, and it will sell.

Doug: You are right on and not getting old. I fought friends and family and continue to buy American. Engineers can do better with technologies that will count economically and environmentally. The very Ford Flex you wrote about - supposed to be a cross over from SUV to car, got bigger than the largest van, why? The well made and excellent sized and featured Honda CRV also got bigger, again, why? Mass is weight and weight translates into gas mileage. Simple math. Engineers are going thr wrong way in size and choice of materials. Refidgerator, in-deed, I hope its big enough to be usefull as a refridgerator when you have to park it because you can no lnger afford the gas to drive it.
John E commented:
I bought American cars over a number of years, but the domestic automakers have abandoned my niche market, which is exemplified by my wife\’s four-cylinder 2001 VW Passat wagon. Its combination of fuel efficiency, safety, practicality, cargo space, ride comfort, styling, maneuverability, handling, workmanship, and fahrfegnugen make it a home-run product, in my view. The only Ford or GM competition in this niche comes from their respective captive Swedish import margues.
Shmooz commented:
I wonder how long these projects have been in development? Maybe 3 to 5 years? I don\’t think it is so easy to just change gears and start redirecting the engineering staff in a new direction. Was that considered in your analysis?
Derby ODonnell commented:
When the great ideas and designs presented as concept cars at trade shows are not dumbed down by overly-cautious executives based on data from focus groups made up of housewives and retirees, American automobile design will finally advance.
Stuart Scott commented:
I worked on a mild hybrid, the GM parallel hybrid pickup. I could see no likely savings based on the facts that there was extra weight to carry around, and the engine would not shut down if the air conditioning was running. I live near Phoenix and would not consider shutting off the AC. It also boasted of an inverter supplying 120 VAC. Using that required leaving the big V-8 running.
Gumby commented:
I just dont understand why mild hybrids is not a standard feature in all new cars by now.. It is so simple to implement right now.. It can boost gas mileage by 10-15% mostly in city mileage. It simply shut down the engine whenever one\’s lead foot is off the gas pedal anytime anywhere. Why are we skipping this important stage? I just dont understand!! Carbuyers can afford to pay extra for mild hybrids for energy conservation !
smurf commented:
I am retired GM saliried employee. Talked another of my friends into buying Cadilac. Now like last one, is in Lemon Law dispute. Engineers don\’t know what is wrong and can\’t seem to fix the engine/transmission noise.

Light Matters: The Unsung Heroes of
Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
