全新一代宋DM采用比亚迪第三代DM技术,混动模式下,发动机和前后轴驱动电机三擎动力齐发,可输出最大功率333kW,最大扭矩740N?m,相当于6.0升排量燃油车的动力输出。踩下油门,反应十分迅速,能体会到强烈的推背感,0-100km/h加速仅需4.9秒,实力媲美180万左右的宝马X6M、保时捷Cayenne Turbo!

第三代DM技术最大的亮点在于全新BSG电机的加入,由此新增HEV串联驱动模式。在低速蠕行时,前驱电机不再兼顾发电任务,而是通过高电压、高功率密度的BSG电机快速发电,这比原来受车轮转速影响的前电机发电模式更高效。在车辆启停时,BSG电机还可将发动机拖至高转速再点火,不仅能达到良好的节油效果,还避免了低转速区间的抖动状况。
由BSG电机控制发动机转速,更加精准高效,辅助快速升降档,减小换挡顿挫,使动力输出更平顺。配合轻重适中的助力转向系统及前奔驰底盘专家汉斯专业调校的底盘,操控更精准,对颠簸路段的震动过滤的比较彻底,快速过弯也不会有明显的倾斜,扎实感十足。
在智能安全上,全新一代宋DM也毫不马虎。BSD盲区监测、LDWS车道偏离预警等对于新手司机来说尤为实用。360°高清全景影像显示在中控大屏上更为清晰,360度无死角显示车周围路况,停车入库都很轻松。

除此之外,一众越级智能配置一应俱全,脚踢感应式电动尾门,可根据用车习惯通过CarPad设定和调节开启高度,解放双手,十分方便。新一代宋DM依然搭载遥控驾驶、VtoL移动电站两大黑科技,来个“无人”移车或是野外烧烤,都能让同行的伙伴惊喜万分

我关注新能源车很久了,我是在今年新提的宋DM,这车在新能源方面采用的是比亚迪的第三代DM技术,这项技术的应用使得宋DM具有更加舒适的驾驶感和更加经济的燃油表现。

全新宋DM采用的第三代DM技术,最突出的特征就是配备的BSG电机,BGS英文的全称为Blet-driven Starter Generator,即皮带传动起动发电机。BSG电机通过皮带链接曲轴,实现自动启停发动机,能量回收,扭矩辅助等功能。

首先,全新宋DM配备BSG电机能够提高动力传输效率,BSG位于发动机前段的位置,通过皮带直接与发动机连接,这样可以最大化的增加能力传输效率。BSG电机为车带来了全新的驱动模式,发动机串联驱动。这样可实现发动机直接带动BGS电机发电,混动动力状态下能效更高。

其次,BSG电机除了提升效率上的,也提高了行车的舒适性,主要是由于皮带传动的BSG代替了起动机,能避免启动冲击,同时主动控制发动机转速,换挡时发动机的转速过高或者过低导致顿挫感,BSG将主动增加或者降低发动机转速,达到无缝衔接。

有了BSG电机电机,车辆在的启动拉升转速可以达到800rp/min,这样能够越过发动机抖动转速区间,实现发动机还未抖动是就能瞬间启动发动机,能避免启动时的抖动问题。

同时我还注意到第三代DM技术与传统的混动技术存在很大的不同,传统的混动技术采用的是48V弱电流,BSG的作用是代替启动发动机,做到快速启停发动机和发电作用。第三代DM技术中,BSG的工作电压为360V-518V,可直接用动力电池供电或者为其充电。BSG电机发电效率高达94%,能保证电量适中保持强劲,发电效率能提升25%,节油率提升15%。

从技术的角度来看,宋DM的采用的第三代混动技术还是很厉害的,BSG电机的配置不仅能提高车辆的动力系统的平顺度减少顿挫感,还能提升开车舒适性,感兴趣车主的话可以去附近4S点体验这车的驾驶感。
