Speedy new models from Porsche AG and Bayerische Motoren Werke AG can beat Toyota Motor Corp.’s Prius not just off the line but also at the fuel pump as efficiency becomes a key standard even for elite racers.

Porsche’s $845,000 918 Spyder hybrid, unveiled at the International Auto Show in Frankfurt, can reach 100 kilometers (62 miles) per hour in 2.8 seconds and gets the equivalent of about 72 miles per gallon, based on European fuel-economy data. That tops the 50 mpg of the basic Prius hybrid.
