Safety trumped aerodynamic vacuum. At unpredictable times, the vacuum would vanish (maybe caused by winds or air currents) and the car would become "unstuck", leaving it in a very dangerous situation.
I fully agree with the reliability and handling of racecars. What good is a racecar if it breaks (fails) before the end of the race? I've seen many interviews from top competitive drivers sorely disappointed in their provided equipment that broke just before the race ended. Racecars that can't handle well look slow on the race tracks compared to the better handling cars, and that very much includes NASCAR. Tires and suspension adjustments are critical to success (tires can be adjusted by air pressure).
The comment about the aerodynamic vacuum under these cars at speed reminded me of the Chaparral 2J car from the Can-Am series in the 70's. The car has side skirts and an on-board "vacuum cleaner' powered by a snowmobile engine which generated a downforce which exceeded the weight of the car. It was so much faster than the competition that it was banned under a questionable rule interpretation. Unfortunately, engineering brilliance in car racing can be overruled by the need to put on a good race for the fans (unfortunate) or by the need to hold down top speeds for safety reasons (probably a good idea).
One comment at Detroit was that all the cars look exactly the same and no longer can we see wild variants and that fact is a shame. Now like dodgems at the amusement park.
Apparently it has all been engineered out and development has led to near perfection in the handling of the aerodynamics.
So now we get to see some good and some very bad painting schemes.
Interesting how the track repairs were lifted out by the cars, someone saying that there is a tremendous vacuum on the underside of the cars.
One Drivers comment that it was like a Michigan Road brought cheers.
No passing spaces in Detroit. He who gets the Pole gets to win the race.
Absolutely, there is far less room for error (likely no room in fact) for those 500 miles since at those speeds, lives are at stake. One teensy, little glitch in something as small as a misplaced fastener, and you could be primed for disaster.
Good point, Beth. It's amazing to learn that IndyCar's number one engineering challenge -- vehicle reliability -- is the same as for production cars. It's true they only need to go 500 miles at the Indy 500, but it doesn't mean that reliability is any less important. In fact, a simple failure -- like the one on Parnelli Jones' vehicle in 1967 -- can be devastating.
Nice job Chuck, on translating the thrill of racing into engineering challenges that other engineers, even if they don't work on the race car circuit, can relate to and are grappling with every day for their own types of products. Those minor design tweaks and keen attention to simulation outcome are what can set one company's offering apart from another--whether it's a highly competitive IndyCar race or components for commercial cars.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
Using almost 200 light-emitting diodes in the front and back of the new 2014 CTS, Cadillac designers are showing how LEDs can change the character of a vehicle.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
