The annual Society of Automotive Engineers International Congress and Exposition has evolved into such a, well, glitzy affair, the uninitiated might easily confuse the glowing, sometimes humming show floor for that of the Consumer Electronics Show or maybe the Specialty Equipment Market Assn. (SEMA) circus.

It hasn't always been this way, and the proof is in what's going on upstairs in Detroit's Cobo Center. In those upstairs meeting rooms is the real deal, the nitty gritty, the backbone of SAE: the technical sessions and paper presentations.

If the hype and holler on the main floor is SAE's Super Bowl, then the technical sessions are where the offensive and defensive coordinators toil in earnest to make it all happen. What they're discussing in those sessions often develops into what's being hawked - eventually - by players on the main floor.

Hardcore SAE attendees don't even hit the main floor. They quietly file upstairs to find out what's really happening in the business. To them, the technologies and ideas on the show floor are yesterday's news.

For SAE '99, WAW's editors have subjectively highlighted some potentially intriguing technical sessions and paper presentations, so that you, too, might become one of the "inner circle." Some of our selections reflect personal biases. Some promise to be illuminating. Some are sublime. And some just look off-the-wall. Decide from these suggestions:
