简介：在AMG50周年之际,这款两座超跑带来了最新的、成熟的F1混动车技术.这款高性能混动车据说最大功率可达1000马力,极速超过350公里/小时,它结合了赛道性能和适合日常驾驶的F1混动技术,并具有绝佳的经济性.这辆车的动力系统由一个加了涡轮增压的燃油发动机和四个电动马达组成,其中一个和涡轮增压器整合在一起,另一个则是通过曲轴箱与燃油发动机直接相连,其余两个则是用来驱动前轮.里面的1.6升V6发动机来自F1赛车,转速可达11000转,在公路车中实属少见,而电动机的转速也高达50000转,一般的转速仅为20000转.这两个马达可独立为前轮提供加速和减速功能,换言之,ProjectONE的前轮可获得不同比率的扭力输送,令车身有更佳的动力表现.在日常情况下,马达可把80％的刹车车动能回收,然后储存在电池内.
