The BMW 6 Series Gran Turismo (2017-2023) is a fastback luxury hatchback that replaced the 5 Series GT, blending sedan comfort with practical cargo space. The 630d variant features a smooth 3.0-liter turbodiesel inline-six producing around 265 horsepower. Reviewers praise its refined ride, spacious rear seats, and generous cargo capacity, though criticize its polarizing styling and hefty curb weight. It's known for impressive fuel economy despite its size and available all-wheel drive (xDrive). The 6 GT suits buyers seeking a premium alternative to traditional SUVs—ideal for executives, empty-nesters, or families wanting luxury car dynamics with SUV-like versatility. Perfect for highway cruising and long-distance touring, though its size and complexity make it better suited for experienced BMW owners comfortable with maintenance costs.
The BMW 630d Gran Turismo features expensive diesel maintenance including DPF cleaning/replacement ($2,000-4,000), AdBlue system issues, and complex air suspension repairs ($1,500-3,000). Turbocharger failures occur around 80,000 miles. Premium fuel, costly BMW parts, and high insurance rates apply. However, diesel reliability is generally good with proper maintenance intervals followed diligently.
