# 2015-2019 BMW 730d The BMW 730d represents the diesel-powered entry point to the 7 Series luxury flagship sedan from this generation (G11/G12). Powered by a 3.0-liter inline-six turbodiesel producing around 265 horsepower, it combines impressive fuel economy with effortless performance and the 7 Series' extensive technology suite, including gesture controls and available executive rear seating. Reviewers praise its refined powertrain, whisper-quiet cabin, and exceptional long-distance comfort, though some criticize the complex iDrive infotainment system. The 730d is particularly celebrated in Europe for delivering flagship luxury with diesel efficiency. It's infamous for depreciation and potential expensive repairs post-warranty, particularly with electronics and emissions systems. **Best suited for:** Executive chauffeur service, business professionals seeking luxury with lower running costs, and highway commuters who prioritize comfort. The diesel makes most sense for high-mileage drivers, though increasingly restrictive urban diesel regulations may limit city access.
The 730d features BMW's reliable B57 diesel engine, but expect premium costs for routine maintenance (specialized oil, filters). Air suspension and complex electronics can be expensive to repair. Diesel particulate filter issues may arise with short trips. Insurance runs high due to luxury classification. Overall more reliable than older BMW models, but maintenance costs remain significantly above non-luxury vehicles.
