外文原文： Cars of TomorrowAutomotive Engineers Team Up to Improve Energy-Saving Technology October 1, 2006?— Mechanical and electrical engineers at DaimlerChrysler, General Motors and BMW have jointly developed a hybrid-vehicle technology that shuts the internal combustion engine off when the vehicle stops. Meanwhile, engineers are working to replace the platinum in fuel cells with cheaper materials, which could lead to viable hydrogen cars. AUBURN HILLS, Mich. -- The high cost of hybrids has kept many people from going green, and a new E study shows that with the cost of gas -- combined with tax credits -- it only takes about three years to break even. Now a new breed of hybrid is going to lessen that time even more. Its the brainchild of not one car company but DaimlerChrysler, General Motors and BMW! They are all working together to create the car of tomorrow. As gas prices go up, the pressure is on to create cars that use less. The hybrid system that were developing, we can apply to any vehicle that we have, Glenn Denomme, a chief engineer of Hybrid Powertrain Programs at DaimlerChrysler in Auburn Hills, Michigan, tells DBIS. It allows for increased performance compared to a conventional SUV and improves fuel economy by up to 25 percent. Denomme says, You can still haul your cargo, but you can still be environmentally sound too. Todays hybrid works best in stop-and-go traffic -- tomorrows hybrid will give you better fuel economy, not only in the city, but on the highway. When the new hybrid is stopped, the advanced system shuts the internal combustion engine off, conserving fuel. When the car starts to move, electric power is used to conserve fuel, adding power from the engine as needed. Speeding up even more, power from both the engine and electric motors are routed to the wheels for greater acceleration. The new technology doesnt stop there! A fuel cell car is 100-percent electric. It takes hydrogen and oxygen, combines it to form water, and at the same time prod
