The Good
The 2015 6-Series boasts impressive performance with potent engines, sophisticated handling, and a truly engaging drive that excites emotional buyers. Its exquisite interior comfort, premium materials, and striking design provide a luxurious experience. For practical buyers, modern BMWs offer decent efficiency for their class, while strong build quality contributes to a sense of long-term value, albeit with typical luxury maintenance.
The Bad
Potential weaknesses for the 2015 6-Series include higher-than-average running costs, particularly for maintenance and repairs, especially on the V8 650i. The iDrive system, while advanced, can be complex for some. Rear-seat space, especially in the Coupe and Convertible, is limited. Watch out for electronic gremlins and common BMW engine issues as the vehicle ages.

Vehicle History Report
What Problems Does the 2015 BMW 6-Series Have?
Engine-specific concerns are more prevalent with the N63 twin-turbo V8 found in the 650i. This engine, known for its power, has a history across various BMW models (including the 2015 model year) of issues such as oil consumption, valve stem seal leaks, timing chain wear, and turbocharger failures. BMW initiated a "Customer Care Package" for earlier N63 engines, addressing some of these issues, but later iterations can still exhibit similar problems as they age and accumulate mileage. The inline-six (N55) in the 640i is generally more reliable but isn't immune to common BMW issues like electric water pump failures, oil leaks from the valve cover gasket or oil filter housing, and fuel injector problems.
Suspension components, particularly adaptive dampers and air springs (if equipped), can wear out over time, leading to expensive repairs. Brake components, especially on the more powerful 650i and M6, are high-performance and thus costly to replace. Recalls for the 2015 model year were relatively few, but significant ones included a potential issue with the power steering system losing assistance (NHTSA Campaign Number: 15V046000) and a more widespread recall for the crankcase ventilation valve heater (PCV valve) that could short circuit and increase fire risk (NHTSA Campaign Number: 17V676000). Always check the specific VIN for open recalls.

What Technology & Safety Features are Included?
Driver-assistance features were comprehensive, though many were bundled into optional packages. Standard safety included anti-lock brakes, stability and traction control, front and side airbags, and active front head restraints. A rearview camera and front/rear parking sensors were also standard. Optional driver aids included:
- Active Blind Spot Detection: Warns of vehicles in blind spots.
- Lane Departure Warning: Alerts if the vehicle drifts out of its lane.
- Active Driving Assistant: Combines forward collision warning, pedestrian detection, and city collision mitigation.
- Active Cruise Control with Stop & Go: Adaptive cruise control that maintains a set distance from the vehicle ahead, even in stop-and-go traffic.
- Surround View Camera: Provides a 360-degree bird's-eye view for easier parking.
- Night Vision with Pedestrian Detection: Uses an infrared camera to highlight pedestrians or animals beyond headlight range.
- Head-Up Display: Projects key driving information onto the windshield.
The 2015 BMW 6-Series was not subjected to crash testing by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS) due to its low volume and luxury segment positioning. However, its robust construction and extensive array of active and passive safety features suggest a high level of occupant protection consistent with BMW's engineering standards. High-performance braking systems and advanced chassis dynamics further contributed to accident avoidance capabilities.

2015 BMW 6-Series Prices and Market Value
Today, in the used market, a 2015 6-Series can typically be found ranging from $18,000 to $35,000, with M6 models commanding higher prices, often above $40,000. This represents significant depreciation, which is common for high-end German luxury vehicles. Factors affecting resale value include mileage, condition, maintenance history (critical for BMWs), engine type (640i often holds value slightly better due to perceived reliability and lower running costs), optional packages, and current market demand. Gran Coupe models tend to be more desirable than the traditional Coupe/Convertible due to their practicality and unique styling.

How Does the 2015 BMW 6-Series Compare to Other Vehicle?
- Performance: The 6-Series offers a compelling blend of power and handling. The 640i's inline-six provides smooth, strong acceleration, while the 650i's V8 is genuinely potent. The M6, of course, is a performance beast. Rivals like the Mercedes-Benz CLS-Class (especially CLS550 or CLS63 AMG) offer similar V8 power and luxury but often lean more towards comfort. The Audi A7/S7/RS 7 provide Quattro AWD advantage and a sportier, more modern interior feel. The Porsche Panamera, particularly S and GTS models, typically delivers a more direct, sports-car-like driving experience, albeit at a higher price point.
- Features: BMW's iDrive, premium materials, and extensive optional features (advanced driver aids, high-end audio) place it firmly in the luxury segment. The Gran Coupe's styling and four-door practicality also stand out. Mercedes-Benz offers a similar array of luxury and technology, often with a slightly softer, more opulent cabin feel. Audi's MMI system is often lauded for user-friendliness, and its interiors are renowned for quality and minimalist design. The Panamera excels in customizable luxury and bespoke options.
- Reliability: This is where the 6-Series, particularly the 650i with its N63 V8, faces tougher scrutiny. While all these luxury cars can be expensive to maintain, the N63 has documented issues. The 640i (N55 engine) is generally more reliable. The Mercedes-Benz CLS and Audi A7 are generally perceived to have comparable or slightly better long-term reliability records, though complex systems across all brands can lead to costly repairs. Porsche Panamera reliability is typically strong, but parts and service are premium-priced.
- Price (Used): The 6-Series has depreciated significantly, offering strong value in the used market compared to its new price. Similar year Mercedes-Benz CLS models are often in a comparable price range. Audi A7/S7 tend to hold their value slightly better, particularly with desirable options. Porsche Panamera typically commands a higher used price due to its brand cachet and driving dynamics.
Alternatives:
- Mercedes-Benz CLS-Class: A strong alternative for similar luxury, style, and V8 power, often with a more compliant ride.
- Audi A7/S7: Excellent if AWD is a priority, offering a sleek sportback design, top-tier interior, and strong performance.
- Porsche Panamera: For those prioritizing driving dynamics and a more performance-oriented luxury sedan experience, but expect higher costs.
- Jaguar XF/XJ: Offers distinct British luxury and styling, potentially at a lower used price point, though reliability can also be a concern.
Final Verdict: Is the 2015 BMW 6-Series a Good Vehicle?
For most, buying this vehicle used is the only sensible option given its significant depreciation. It's potentially worth buying if you:
- Have a substantial budget for premium fuel, maintenance, and potential repairs.
- Can find a well-documented example with a full service history, ideally from a BMW specialist.
- Prefer the 640i (inline-six) for potentially better long-term reliability and lower running costs compared to the 650i's V8.
- Are drawn to its distinctive styling, especially the Gran Coupe, which offers a good balance of sportiness and practicality.
Avoid if you're seeking an economical daily driver or are on a tight budget for upkeep. It's a rewarding car for the right owner who understands and accepts the commitments of luxury German car ownership.
