去看官网活动进度条。比如现在是5号和132的活动。
或者直接科技树上，看哪个有%符号的。就是有打折

巴哈有人統計最近幾年每個月的科技線打折是哪些車，不過參考性不大，要讓哪條線打折基本上還是看WG心情，目前比較能確定的就是有通行證那3個月的6條打折線通常有3條會和當前的通行證最終獎勵有關，剩下3條有時候會和平衡調整有關（例如不久前bc25剛加強就打折，更早之前7號和百夫長也在加強後不久開打折）

每个月底官网会通知下个月打折线 几年前的你只能去翻官网新闻 只要新闻没删就能查的到

美服官网以前有看到过练车线集合

什么，一样的I P我也一样买不起车，棺材车就是打折的时候练出来然后最后几天买的，但是本萌新玩无头TD是真玩不好92早点出来了不过毕竟不如5355直接不要了。60TP是我第一辆十级，当时倒是原价买的。有好多八九级车点出来了但没钱买就中断练线了。长期保持四到六条线一起练真的太耗银币了，现在M103又马上要点出来了，换完车又要没钱咯

打折的银币线会有％符号

任务那里有的！
