Performance Metrics - Model Y Performance accelerates from 0 to 60 mph in 3.3 seconds and 0 to 100 km/h in 3.5 seconds [1] - Range increased to 306 miles (EPA cycle) or 580 km (WLTP) due to new cells and efficiency improvements [2] Aerodynamic Enhancements - New Model Y Performance features improved aerodynamics with a longer front splitter, rear diffuser, reduced ride height, and extended rear spoiler [2] - Aerodynamic drag is significantly reduced compared to the previous performance model, partly due to new arrow covers on the arcade wheels [4] Design and Comfort - The vehicle retains the confident cross car lamp from the premium Model Y [3] - The new Model Y Performance maintains the comfort of the premium product while offering a high-performing driving experience [5] - Sporty interior emphasized through carbon fiber, micro suede, badging, and aluminum features [6] Handling and Stability - Front fascia is re-profiled with a longer front splitter to improve downforce and high-speed stability [3] - New tires provide significant lateral and longitudinal grip, enhancing acceleration and deceleration [4] - Suspension and aerodynamic changes soften the rear end for an overall better riding experience [7]

车速越快、风阻越大、能耗越高，为了降低能耗，现在的汽车流行卷风阻系数，不少汽车带有一些 空气动力学配置，比如隐藏式门把手、尾翼，有的配备扩散器。什么是扩散器？能干啥？ 什么是扩散器？ 扩散器，是一种装在车尾底部的扰流装置，多见于性能车和超级跑车。大部分扩散器外观比较低 调，但也能增加运动氛围。 作为一个空气动力学的组件，扩散器主要利用流体速度的大小与压强成反比的原理，将车辆底盘下 部的气流梳理后快速导出，增加赛车底盘下部气流的速度，从而形成低压区，达到增强车辆下压力的效 果。目前，F1赛车上前翼与尾翼可提供约60%的下压力，而底盘扩散器能提供40%的下压力。 扩散器如何产生下压力？ 汽车在高速行驶时，空气会从四面八方绕过汽车，但相较于底盘，车顶距离更长、表面更光滑平 整，使得上方空气流速较下方更快。根据伯努利方程，流速大的地方压强小，因此汽车上方压强小于下 方，从而产生向上的升力。 向上的升力对普通民用车来说问题不大，但在极高速或赛道上，一点点升力都会影响动态（安全） 性能，因此需要一个较为稳定的力，让车辆较稳定地呆在地面，或者说将其"按"在地面，于是就有了扩 散器。 当空气进入车辆底盘区域后，在扩散器的抽吸 ...
