宝马和奔驰的电车跑得比EPA预估里程更远

Core Insights - The article highlights the significant discrepancies between the advertised and actual range of electric vehicles (EVs), emphasizing that various factors such as temperature, tire condition, and driving speed can affect performance [4][6][10] - Consumer Reports (CR) conducted tests showing that over half of the 30 EVs tested had lower highway range than their EPA estimates, with some models falling short by as much as 50 miles (approximately 80 kilometers) [10][12] - The article calls for a modernization of the EPA's testing standards to provide more accurate and practical information for consumers regarding EV range [17] Testing Methodology - CR performed highway range tests by driving fully charged vehicles at a constant speed of 70 mph (approximately 112 km/h) until the battery was depleted [7][9] - The tests revealed that many vehicles could still travel additional miles even after the range indicator showed zero [9][10] - The testing conditions were controlled to ensure optimal performance, including temperature regulation and tire pressure adjustments [22][21] Findings from Tests - Among the tested vehicles, 18 models (60%) did not meet their EPA estimated range, with the Ford F-150 Lightning showing a 50-mile (approximately 80 kilometers) shortfall [12][16] - Some models exceeded their EPA estimates, such as the BMW iX, which achieved a range of 370 miles (approximately 595 kilometers) compared to an EPA estimate of 309 miles (approximately 497 kilometers) [14] - The Mercedes EQS 580 was noted as the top performer, achieving 380 miles (approximately 611 kilometers) on the highway, slightly exceeding its EPA estimate [14] Charging and Performance Evaluation - CR's evaluation also included assessments of charging speed and convenience, focusing on both AC slow charging and DC fast charging capabilities [24][26] - The ease of use of charging interfaces and the availability of navigation features to locate charging stations were also considered important factors in the overall assessment [25][26] - The article emphasizes that the charging experience is critical for consumers, as they may interact with charging interfaces more frequently than with traditional fuel pumps [26]
