Core Viewpoint - The automotive industry is witnessing a shift where traditional fuel vehicles and new energy vehicles (NEVs) are increasingly incorporating larger fuel tanks, reflecting a compromise between idealism and practicality in consumer preferences [3][4][5]. Group 1: Industry Trends - Audi has retracted its plan to cease development and sales of fuel vehicles by 2033, indicating a need for a diverse product lineup that includes electric, plug-in hybrid, and internal combustion engine models [3][4]. - Many Chinese automakers, initially focused on pure electric vehicles, are now pivoting towards plug-in hybrid models, recognizing the importance of fuel tanks in consumer purchasing decisions [4][5]. - The retail sales of plug-in hybrid vehicles (including range-extended models) increased by 28% year-on-year in the first five months of this year, reaching 1.69 million units, with a projected growth of 76.9% in 2024 [5][40]. Group 2: Technical Developments - The advancement in battery technology has led to plug-in hybrid models achieving electric ranges exceeding 300 kilometers, significantly improving their market positioning [4][5]. - The fuel tank sizes of new energy vehicles are now often larger than their traditional fuel counterparts, with some models featuring tanks up to 91.5 liters [5][6][13]. - The average fuel tank capacity of new energy vehicles in China has increased by 52.6% from 2017 to 2024, reaching 58 liters, aligning closely with traditional fuel vehicles [15][22]. Group 3: Consumer Behavior - Consumer anxiety regarding charging infrastructure remains a significant barrier to the adoption of electric vehicles, prompting manufacturers to enhance fuel tank capacities as a practical solution [18][19]. - The shift in consumer preference towards larger fuel tanks in new energy vehicles is driven by the need for convenience and reliability in refueling options [19][43]. - The introduction of policies that treat plug-in hybrids and pure electric vehicles equally in terms of subsidies has further accelerated the growth of plug-in hybrid models [40][43].
