Core Viewpoint - The article discusses the increasing accessibility and adoption of advanced automotive technologies, particularly rear-wheel steering, which was once exclusive to high-end luxury and performance vehicles. Group 1: Technology Accessibility - Many high-end features that were once exclusive to luxury vehicles are now becoming standard in various models, including electric vehicles [1][2] - Technologies such as air suspension and advanced driving assistance systems have seen significant growth in recent years [2] Group 2: Rear-Wheel Steering - Rear-wheel steering, previously found in high-end models like Porsche 911 and Lamborghini Aventador, is now being standard in many domestic electric vehicles at lower price points [5][7] - Examples include models like the Tengshi N9 and Xiaopeng X9, which offer rear-wheel steering at prices around 400,000 and 300,000 respectively, with some models even exceeding 200,000 [8][10] Group 3: Benefits of Rear-Wheel Steering - Rear-wheel steering significantly enhances maneuverability, allowing larger vehicles to have a turning radius comparable to smaller cars, improving parking and navigation in tight spaces [10][13] - The technology also enables advanced features like crab walking, which relies on rear-wheel steering [14] Group 4: Market Penetration and Challenges - Despite its advantages, rear-wheel steering has a low global penetration rate of only 1.2%, indicating limited adoption compared to other technologies [17] - The complexity and cost of implementing rear-wheel steering systems, along with the need for additional space and maintenance considerations, hinder widespread adoption [53][67] Group 5: Historical Context and Evolution - The evolution of rear-wheel steering began in the late 19th century, with early attempts using simple mechanical systems, leading to its application in agricultural and military vehicles during the 20th century [18][22][24] - The transition to passenger vehicles occurred in the late 20th century, but early systems were passive and had reliability issues, prompting the development of more advanced active systems [29][32] Group 6: Future Prospects - Despite current challenges, domestic companies are investing in rear-wheel steering technology, which may lead to increased accessibility and innovation in the future [70][72] - The potential for domestic suppliers to disrupt the market and drive down costs is highlighted, suggesting a promising outlook for the technology's adoption [72][73]
