Diesel lirthei hrang hrangte hian an thawh dan a inang lo a, mahse a tlangpuiin speed 200 km/h aia chak an thleng thei. Dik tak chuan, a hlutna bik chu thil hrang hrangin a nghawng a, chu chu lirthei engine power, drivetrain, body design, leh performance atana optimized a nih leh nih loh te hi a ni.
High-performance diesel lirthei thenkhat chuan top speed 250 km/h emaw a aia sang emaw pawh an thleng thei. Mahse, nitin diesel lirthei tam zawk tan chuan hetiang speed sang tak thleng hi a tlem hle.
