# 2005-2010 BMW 630i Coupe The BMW 630i represents the entry point to the sixth-generation 6 Series, featuring a 3.0-liter naturally aspirated inline-six producing 258 horsepower. This elegant grand tourer emphasizes style over outright performance, with Chris Bangle's controversial flame-surfaced design polarizing opinions—some found it striking, others awkward. Reviewers praise its luxurious cabin, smooth engine, and comfortable highway cruising but note it feels underpowered compared to V8-equipped siblings. The complex electronics and iDrive system proved troublesome, while maintenance costs remain typically expensive for BMW. Today, it suits enthusiasts seeking affordable 6 Series elegance who prioritize style and grand touring comfort over performance. It's ideal for long-distance highway driving rather than spirited back-road runs. Prospective buyers should budget for repairs and seek well-maintained examples with service records.
The BMW 630i features a naturally-aspirated 3.0L inline-6, avoiding the turbo issues plaguing later models. However, expect expensive maintenance: electronic gremlins (iDrive, sensors), oil leaks from valve cover gaskets, and pricey dealer-only parts. Premium fuel required. Insurance runs high due to luxury/performance classification. More reliable than V8 variants but still costly to maintain.
