"A senior product development executive at Ford has warned that a dearth of US suppliers capable of producing key petrol-electric hybrid components places a big question mark over the future competitiveness of the country's automotive industry.
Phil Martens, Ford's executive vice-president of product development, said the car giant, which is preparing to ship a small hybrid sports-utility vehicle (SUV) later this year, had to turn to foreign suppliers for access to a majority of key components to build the company's first hybrid, the Escape Hybrid.
"What is it going to take for
suppliers to invest in this type of R&D in the United States?" Mr Martens asked in a recent interview. "It's a burning issue. We need to think about how complicated a task to launch the technology in the United States," he said. "We don't have battery suppliers that can deliver , we don't have regenerative brake suppliers that can deliver what we need, and we do not have the level of software engineering that we need."

Given that few automotive suppliers in Japan had practical expertise to help Toyota create a hybrid car, Toyota developed its own expertise internally in key areas, such as battery and regenerative brake technology, and a computer control system that helps the vehicle to switch seamlessly between the petrol engine and the electric propulsion system when driving the vehicle. Toyota then worked with suppliers to hone knowledge and skills to design and manufacture key hybrid components, the company said."
