SAE 100 Future look: What technology will drive passenger vehicles in the future? Ask a number of automotive engineers this question, and you'll likely get an equal numbers of answers.

I'd wager that's no less true today than it was when SAE began 100 years ago.

The speculation in those early days of SAE about the future of automobile propulsion and what technology would ultimately prevail centered on steam, electricity, internal combustion, or some combination of the three. As we know, by the mid-teens the internal-combustion engine had won out.
