多年来,迈凯伦是超豪华品牌中对 SUV 最坚定的「拒绝者」。 其前 CEO Mike Flewitt 曾多次强调,「SUV 不符合迈凯伦的 DNA」。在迈凯伦的自我叙事中,轻量化、中置引擎与驾驶纯粹性,长期被视为其最重要的 工程原则,而 SUV 的高重心、大尺寸与重车身,似乎天然与之相悖。 然而,这一立场正在悄然瓦解。 据海外知名汽车媒体 motor1 报道,迈凯伦上个月向其经销商展示了一款采用混合动力的五座 SUV 车型,内部代号「P47」。 尽管迈凯伦官方尚未正式确认,但种种迹象表明:这台车已进入工程验证后期,预计将于 2028 年亮相。 曾经的「绝不」,如今变成了「即将」 迈凯伦对 SUV 的抗拒曾有其底气——这份底气,源于它从诞生之初就与赛道深度绑定的血统,以及对工程极致近乎偏执的追求。 1963 年,布鲁斯·迈凯伦(Bruce McLaren)创立车队时,关注的目标就是如何打造真正为胜利而生的竞赛机器,无论是在 F1、耐力赛还是印第体系中, 对极限性能的追逐始终居于迈凯伦体系的核心位置。 2009 年,迈凯伦发布 MP4-12C 正式重返民用跑车市场。这辆车并未沿用传统超跑依赖大排量自然吸气或奢华内 ...
