燃油经济性依然是影响消费者购车行为的主要因素,并日益成为在过去十年来购买决策的关键驱动力。尽管汽车整体重量和动力系统对燃油经济性具有重大的影响,然而,轮胎却可以提供进一步提高车辆燃油效率的机会。据估计,滚动阻力降低10%可以使乘用车的燃油经济性提高1～2%。过去的几十年中,轮胎技术研发团队已开发 Fuel economy continues to be a major factor affecting consumers’ car buying and is increasingly becoming a key driver of purchasing decisions over the past decade. While overall car weight and powertrain systems have a significant impact on fuel economy, tires can provide the opportunity to further increase vehicle fuel efficiency. It is estimated that reducing the rolling resistance by 10% can improve the fuel economy of passenger cars by 1-2%. Tire technology R & D team has been developed over the past few decades
