Hybrid car pioneers Toyota and Honda say they probably can't build enough of the fuel-saving models to meet demand this year as rising petrol prices ignite consumer interest, Bloomberg News reported. The news agency said sales of the three petrol-electric models, Toyota's Prius and Honda's Insight and Civic Hybrid, are up 50% so far this year but a Prius model change late this year and a production ceiling at Honda mean sales may be limited to about 50,000 cars in 2003.
