Despite his early, wilder visions of Automobiles of the Future (1966), Stambler notes here that the old internal combustion engine still unexpectedly reigns supreme, and that modifications on it are more likely in the short run than any radical alternative. The biggest change since the appearance of his Automobile Engines of Today and Tomorrow (1972) is that fuel conservation has been added to pollution and safety considerations as directives for research, and so his descriptions of the previously covered Wankel, gas turbine, and other alternatives (both operational and experimental) is likewise modified. Still implicitly rosy about the economy, Stambler foresees a two-car family garage with a large convertible transport/bus/camper for special trips and a very small runabout, possibly flywheel-powered, for everyday shopping and commuting. Also apparently in the works is a totally electronically-controlled vehicle which will maximize i.c.e. efficiency (and, as described, take over most of the driving). This ends, as such projects must, with visions of supercooled, solar, and laser-powered models; but Stambler's appeal to auto buffs lies not in such futuristic speculation but in his straightforward, uncondescending presentation of more immediate technical issues.
