而我最近发现，刘翔其实也“上车”了，他代言了新能源品牌：智己汽车。
这让我有点意外，也让我非常好奇。
意外是因为这是刘翔第一次代言新能源品牌，没想到选择了一家新势力。意外之余，我更加好奇，智己靠什么打动了这位体坛传奇、世界冠军？
带着这份好奇，我最近试驾了智己推出的最新产品LS8，顺道扒了扒产品背后的技术，尝试解答我的疑惑。
LS8是一款车长超5米的中大型SUV，和宝马X5、奥迪Q7尺寸相近，但没那么贵，预售价25.98万元起，最终价格将在4月16日正式上市时揭晓。
为了有更直接的对比，我还专门找了一位特殊的同事，共同体验了一下LS8。
这两天我开着智己LS8，直接在停车位原地启动智能辅助驾驶，早晚高峰通勤省了不少心。每天它都带着我在高架桥上丝滑行驶：
快下匝道时会主动变道。
!Image 23 加塞也非常果断。
需要掉头时，也是直接一把过，只跨了一个车道。
!Image 25 环岛这种复杂场景下的进出也很顺畅。
前面这些都算是“开胃菜”，最后重点介绍一个我在北京西三环遇到的场景，当时确实让我紧张了一下。
说实话，之前我很少开车到西三环这边，对路况不太熟，所以我一路上很小心，随时准备接管。
期间经过了一个让我印象非常深刻的桥洞，桥洞本来就是一个经典难题，因为它是一个盲区，相比前面提到的那些场景，风险要更高，很考验AI司机的预判和及时决策能力。
路不熟+盲区转向，本来这题就难，结果当时又遇到了“附加题”，这个桥洞转向的拐角特别小，这也就罢了。
没想到转弯后，迎面直接驶来了“一串小电驴”，让我头皮发麻。我紧盯着智己LS8，只见它迎着车流，辗转腾挪，顺利通过，表现还挺让我意外的。
有意思的是，智己LS8不仅给我配了个AI司机，还给我找了个AI助理。比如说我上班路上饿了，可以通过车机对话，提前点个饭送到公司。
全程不需要动手，通过对话就能完成支付下单，到公司直接开吃。
这种“司机+助理”的体验，由智己携手两位合作伙伴共同打造。
其中一位是阿里千问，这是千问大模型首次上车，有了千问赋能，智己车机就像长了“手脚”，不光能听懂我说的话，还能根据我的指令，执行任务，比如刚才帮我点餐。
据说这还是小试牛刀，智己未来会进一步打通阿里生态，在车端连接飞猪、淘宝等服务，动动嘴就能买票和购物。
另一位则是自动驾驶头部Momenta。目前LS8搭载的IM AD MAX系统，就是由Momenta与智己联合打造，可以说是我今年体验过最丝滑的智能辅助驾驶。
这种表现也符合我的心理预期，因为我在上车前就细扒了这套系统背后的技术，发现软件硬件都挺能打的。
先说软件，核心算法引入了Momenta一段式端到端大模型，用一个模型打通驾驶任务全过程，减少了信息损耗，更加拟人。
然后再看硬件，LS8的感知硬件包括了1个520线超视域激光雷达，最远有效感知距离达到了300米，具备智能凝视功能。所谓智能凝视，就是激光雷达在40°水平夹角范围内，通过提高收发器组的处理频率，使凝视区域的角分辨率达到0.05°×0.05°，让该区域的点云密度媲美1040线，感知更清楚。
而最底层的算力芯片，则采用了英伟达Thor，算力达到了700TOPS，这是目前主流方案的顶级水平，当下绝对够用，而且很长一段时间都不会过时，可以面向未来升级。
预埋的充沛算力给了智己底气，其明确表态LS8拥有更新到下一代系统IM AD ZETA的能力，据说到时大模型参数量会提升3-4倍，性能拔高20倍。
以上都是我一拿到智己LS8，直接就能感知到的智能化体验和技术。在使用了一段时间后，我还发现，原来LS8更底层的底盘和动力，也藏着不少黑科技。
先从最底层的底盘系统说起，LS8的底盘其实和传统汽车很不一样。举个例子，前面有提到，LS8跨一个车道掉头，而且一把过，这看似基操，实则不然。
首先，之前说过LS8车很大，车长超过了5米，这种车掉头一般都很困难，不会这么丝滑。
其次，注意看方向盘，掉头时也就打了半圈。为什么会这样？
这背后得益于LS8搭载的灵蜥数字底盘3.0，其核心技术是全线控四轮转向系统，先说线控技术，LS8搭载了行业首个符合最新国标的全线控底盘，也是行业首次将线控转向技术下放到三十万级。
所谓线控转向，是指拿掉了方向盘的机械管柱，改用电子信号控制底盘。转向的响应速度因此变得更快，具体到LS8这款产品， 速度达到了传统结构的4倍。 方向盘的转向比（方向盘转角：车轮转角）同时还会根据速度自动调节，比如说刚才我掉头时，车开得慢，转向比就很小，方向盘稍微一动，车轮就跟着转向，转半圈就打满了，完成了掉头。
而当车辆速度变快时，转向比也会跟着变大，比如我有一次去首都机场接朋友，在机场高速变道时，就感觉转向手感很不一样，车子明显开着更稳了。
这套系统同时也让车辆的后轮可以转向，最大转向角度达到了24°。所以LS8这台车长超5米的大车，才能有媲美4米小车的灵活度，实现轻松掉头。
灵蜥数字底盘让大车也好开，解决了家庭用户的一大痛点。LS8搭载的恒星超级增程系统，则回答了家庭用户另一个关心的问题：
大车能不能省钱？ LS8可油可电，平常上下班，用电就够了。因为这套系统装了一块66度的大电池，官方标的纯电续航参数是430km，我在实测后发现标得很实，我和同事两个人，从机场跑到市区，百公里驱动电耗是12.1度。
等到了周末或者节假日出远门，纯电续航可能顶不住了，再考虑用油。同样是在CLTC工况下，智己LS8满电满油能跑1605km，百公里综合油耗不过2.54L，而且可以加92号汽油。最近油价大涨，这套系统无疑能省不少钱。
总的来看，从智能到底盘，再到动力，这款车能盘的黑科技还真不少，而且都实打实地为用户创造了价值，让我日常开车更省心，用车更省钱。
与我一路同行的编辑部同事，则对这辆车有更深切的体会。 我的这位同事，其实是一位BBA车主。他之前不太关注新能源产品，一开始也不是很愿意跟着我试乘智己LS8。在我~~威胁要把他蒸馏成Skill~~一番好言相劝后，他才同意和我一起体验一下。 结果刚坐上车，直接啪啪打脸。他一坐上副驾，我就唤醒车机“你好智己，打开副驾零重力座椅、打开座椅加热和按摩”，在点击屏幕，确认后排无人后，车机按照我的指令，调整好了座椅。只见我这位同事，此时直接躺在副驾上说：
> 这绝对比我的车舒服。
然后他就打乱了我的计划。本来按照原计划，我打算只带他在车里坐一小会儿。
然后就要赶着去首都机场接人。
结果他非要让我再带着他兜一圈，我就打发他上了后排，然后一路上的他be like:
“这后排座椅有腿撑，比我那车舒服”。
“后排还有电视，‘你好智己，打开后排屏幕’，你B站会员呢？”
“这听着音质也很棒，哦用的是B&O的音响，挺地道。”
“诶这电视下面还有个冰箱”。
这一套冰箱彩电大沙发+B&O音响体验下来，我这位同事直接服了，对传统豪车的滤镜碎了一地。 类似的前后转变，这两年我已经见怪不怪了。像他这样的传统豪华车主我见过很多，这些老车主以前没得选，甘愿为豪华品牌支付溢价，现在则开始转投新能源的怀抱。 这意味着传统豪华的溢价时代，在中国已经终结。智己LS8正是这一时代趋势下的代表，背靠上汽集团，其率先将百万级的底盘素质、最前沿的智驾和智舱，同时下放到二十五万级，用AI重新定义豪华，从BBA手上夺回了定价权。
我想，这也是刘翔选择成为智己代言人的原因。世界级体坛传奇携手大厂国家队旗舰，源自精神上的同频共振，毕竟他们都在各自的赛场上，冲击了此前由欧美主导的格局。
他们共同证明，没有跨不过去的栏杆，也没有打不破的壁垒。
