# 2015-2022 BMW 730i The BMW 730i represents the entry point to 7 Series luxury, pairing a 2.0-liter turbocharged four-cylinder engine (258 hp) with the flagship's opulent cabin and advanced technology. Available in standard and long-wheelbase forms, it offers exceptional rear-seat comfort, cutting-edge features like gesture controls, and a serene ride quality. Reviewers praise its refinement and efficiency but note the four-cylinder feels underwhelming in such a large sedan, particularly compared to six- and eight-cylinder alternatives. The 730i gained notoriety for bringing four-cylinder power to BMW's flagship, controversial among purists but appreciated in efficiency-focused markets. **Best suited for:** Executive chauffeur service, urban luxury driving, and buyers prioritizing technology and comfort over performance. Ideal for those wanting 7 Series prestige with lower running costs, though enthusiasts typically recommend upgrading to the 740i.
The BMW 730i features expensive maintenance including premium fuel requirements, costly brake replacements, and complex electronic systems. Common issues include air suspension failures ($2,000-4,000), timing chain problems, and oil leaks. Insurance runs high due to luxury classification. BMW's maintenance program may cover some costs initially, but post-warranty repairs are notably expensive.
