根据美国耶鲁大学和哥伦比亚大学共同发布178国环境表现指数报告，中国排名118，具体到空气质量这一项上，中国则排到了176名，其中汽车尾气对大气污染占比达到7成，环境问题不容忽视，中国消费者的节能减排意识日益增强。在此情况下，高动力输出、低燃油消耗的小排量涡轮增压发动机应运而生。

出于对动力趋势的准确把握和对消费者需求的深刻洞见，从2012年起东风标致旗下的车型陆续开始搭载“E动战略”下的多款全新发动机，将领先的动力科技付诸于产品，顺应时代需求更引领行业技术趋势。老款408搭载“E动战略”下首款发动机——1.6L CVVT技术发动机， 成功验证了“E动战略”高效、经济、环保的技术领先性，今天运用更多革新性技术的1.2THP涡轮增压直喷发动机又率先助力新一代408，也再一次证明了408之于东风标致不可动摇的战略地位。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  

“小T大作”的1.2THP发动机

作为“E动战略”的最新成果，1.2THP涡轮增压直喷发动机高性能、低油耗、超平顺的性能优势，显示了PSA集团在核心动力领域的研发实力。1.2THP发动机以136马力的最大功率、230N•m的最大扭矩，领先实现比肩主流2.0L、1.4T发动机的动力输出水平。同时，匹配STT发动机智能启停系统，使得东风标致408的1.2THP车型百公里综合油耗低至5.2L，可满足欧6排放标准，是真正的“小T大作”。

与连续8年荣膺“国际发动机大奖”的1.6THP涡轮增压直喷发动机一样，1.2THP发动机也采用了连续可变排气正时系统，在有效提升低速扭矩、保证低速动力性能的同时，显著增强高速功率表现；高压缸内直喷技术使燃油雾化更加充分，加上精确控制的喷油时刻和喷油量，燃油利用率得以显著提升；另外，全铝合金缸体技术的应用使其比同排量铸铁缸体机身减重接近1/3，有效实现车身轻量化，结合涡轮增压、中冷技术、排气歧管耦合技术、ECU控制连续可调变排量机油泵等众多先进技术，让每滴燃油都不虚耗；尤其值得一提的是，1.2THP发动机还采用了特别的平衡轴技术，有效减少了运转振动，首次采用的内置湿式正时皮带系统，使发动机运转噪音进一步降低，平衡轴与曲轴之间优化设计的传动齿轮则明显减轻了运动噪音，轻松抵达全新“静”界。

1.2THP涡轮增压直喷发动机在技术上不仅延续了1.6THP明星发动机的性能优势，也凭借多项革新性技术的应用，完成了小排量发动机的性能突破，从而实现了高性能、低油耗、超平顺的过人表现。
