Toyota develops chips for hybrid cars to boost fuel efficiency

Toyota Motor Corp (7203.T) has developed a computer chip for its gas-electric hybrid cars that could boost fuel efficiency by 10 percent and allow the automaker to install the hybrid system on more of its vehicles.
The maker of Prius hybrids and auto parts maker Denso Corp (6902.T) have jointly developed a semiconductor using a silicon and carbon compound that limits power loss and allows for a smaller hybrid system, Toyota said on Tuesday.
