Core Viewpoint - The article discusses the design and engineering principles behind the handling and comfort of the Li Auto i6, emphasizing the importance of physical attributes and user experience in vehicle performance [1][3][4]. Summary by Sections Vehicle Dynamics - Vehicle handling and comfort are determined by four main physical attributes: weight, wheelbase, center of gravity, and suspension structure [4][5]. - The tuning process involves a trade-off between "bouncing" and "swaying," where a stiffer suspension enhances handling but sacrifices comfort, while a softer suspension improves comfort but can lead to motion sickness [5][6]. Design Philosophy - The company aims to use rational quantitative data to address subjective user experiences, ensuring that the i6 provides enjoyable driving dynamics within a safe operational range [6][8]. - The i6 is designed to enhance "bouncing" to improve driving pleasure, particularly in the context of a mid-range SUV [5][7]. Hardware and Safety - The i6 features high-end hardware, including a front double-wishbone and rear multi-link suspension, which are typically found in luxury SUVs, contributing to its performance and safety [7][8]. - The vehicle's chassis performance is rated at 90% of its potential to maintain a safety buffer, reducing accident rates [2][8]. Control Systems - The company has developed its own control systems for the vehicle, integrating ESP, steering, and braking to enhance drivability, even for novice drivers [2][9]. - The i6 allows for adjustable performance settings, enabling users to experience driving pleasure without pushing the vehicle to its limits [9][10]. Emotional Experience - The i6 simulates the emotional excitement of driving a supercar without requiring extreme speeds, providing a unique driving experience [10][11]. - The development of the vehicle's chassis is a meticulous process, relying on the expertise of engineers and product managers to ensure high-quality performance [11][12]. Industry Context - The advancement of the Chinese automotive industry has enabled Li Auto to achieve significant self-research capabilities in chassis and software, enhancing the value proposition for consumers [13][14]. - The article highlights the positive feedback loop between improved product quality and rising consumer expectations, benefiting both users and manufacturers [14].
