Suppliers are integral to new technology in the auto industry to an extent not true since the early years of the 20th century, when ventures such as Ford began as mere assemblers, not manufacturers. That will be highlighted on Monday at the 21st PACE “academy awards” for supplier innovation. (For those not in the know, Monday’s the opening night of the SAE [Society of Automotive Engineers] in Detroit.)
It’s always nice when you come across an answer that addresses a question that you’ve wondered about? When I saw that Vox, a relatively new site that says it has “the smartest thinkers, the toughest questions” to “explain” our confusing world to us, was running a post on which uses less fuel, running the A/C or opening the windows, I figured I could put the question to bed. While I did find out about the windows down vs air conditioning thing, I also found out that the smart thinkers over at Vox may not be as smart as they think they are. (Read More…)
Okay, so it’s not The Christmas Story, but while trying to track down a since deleted summary of an upcoming Society of Automotive Engineers paper that leaked details of the 8 speed automatic transaxle that the 2015 Corvette will offer, I came across another SAE paper concerning the Corvette, this one published in 1961, titled The Corvette Story. In 1961, just 8 years after the first Corvettes went on sale, fiberglass bodied cars were still a new thing. Chevrolet engineer P.J. Passon’s paper for the SAE goes over the processes involved in making the Corvette bodies and then how the cars are assembled. He discusses the 1961 Corvette’s engineering features and explains why GM went with fiberglass instead of steel and also why mass-market Chevrolet was making and selling a sports car with limited market appeal. I’m sure that anyone with an interest in Corvettes and Corvette history will find it worthwhile, though it’s also a nice snapshot of advanced materials manufacturing circa 1961.

BUILDING THE CORVETTE
In its brief life span of eight years, the Corvette has undergone rapid character development. It has built up a clientele all its own – demanding, but enthusiastic. Their attitude is contagious, and progress has come fast. I do not intend to cover the history of the Corvette this morning, except to say that its roadability has increased since 1953 in roughly the same proportion as its power-to-weight ratio or approximately two-to-one.

“Things they teach you in the classroom don’t matter until you have a chance to apply them.” So says Julia Cline, an incredibly bright and impressive woman. And for the past three years, Julia has been doing quite a bit of applying.
It’s not known if the leak was intentional or not, but the summary of a paper initially published by the Society of Automotive Engineers, since taken down from the SAE site, says that a new eight speed automatic transmission, given the designation 8L90 by General Motors, will be introduced in the 2015 Corvette, on sale next fall. The all-new 7th generation Corvette is currently offered with GM’s 6L80 six speed automatic and a seven speed manual gearbox. The 8L90 is described as being designed for rear-wheel-drive applications and variants will likely be used in GM’s fullsize pickups and in rear wheel drive Cadillacs.
The 8L90 has about the same overall dimensions as the 6L80, and is said to be able to handle up to 737 lb-ft of torque. It has a shorter first gear for better launch acceleration, an overall ratio spread of 7.0 and three speed sensors for better shift response. Other benefits are said to be better fuel economy, improved performance and a quieter car with improved NVH levels. (Read More…)
The SAE unveiled their latest standard for quick-charging electric vehicles and plug-in hybrids that could cut charging times to as short as 20 minutes.
Today, members of CHAdeMO congregated in the 7th floor auditorium of Tokyo’s Big Sight for CHAdeMO’s General Assembly 2012. CHAdeMO is a consortium of mostly Japanese companies with the target of establishing a standard for the charging of EVs. Also in the room was an invisible, but giant Godzilla. They called him “The Combo.” The combo is the product of (in Japanese views) an unholy alliance between U.S. and German OEMs which agreed on their own plug. The CHAdeMO and The Combo are utterly incompatible. Sparks are already flying. (Read More…)
Even though the Nissan Leaf and Mitsubishi i already have their own standard for “quick-charge” stations – known as CHAdeMO, a standard supported by Nissan, Mitsubishi, Fuji Heavy Industries (parent company of Subaru) - the SAE is apparently pitching its own standard of quick-charger outlets (pictured above), creating a situation that would be akin to having certain cars only compatible with certain gas pumps.
The Society of Automotive Engineers World Congress held in Detroit every April serves a number of functions for the automotive engineers’ professional association.
I am a mechanical engineering student looking to learn how to work on cars.
My friend has given me the opportunity to take his 1988 Mazda B2200 extra-cab 5-speed. When I drove it, I saw why. The catalytic converter has broken off, and apparently pieces of it are in the exhaust. Would it be possible to just replace the catalytic converter, or should I replace the whole exhaust?
