If you're into luxury sedans with a serious dose of sportiness, you're going to want to stick around. This car isn't just a mode of transportation; it's a statement. It blends the sleek profile of a coupe with the practicality of four doors, offering a compelling package for those who refuse to compromise.

So, buckle up, because we're about to get up close and personal with the 2018 BMW 640i Gran Coupe.

Exterior Elegance and Presence

Let's start with the looks, because, let's be honest, the 2018 BMW 6 Series 640i Gran Coupe is a head-turner. BMW really nailed the design language with this generation. The Gran Coupe silhouette is arguably one of the most elegant four-door coupes ever conceived. It boasts a long, flowing roofline that gracefully tapers towards the rear, giving it a distinctly sporty and elongated profile. The signature kidney grilles are present, as expected, but they're integrated beautifully into the sculpted front fascia, flanked by sharp, aggressive LED headlights that give the car a piercing gaze. The proportions are just spot-on. It’s long, wide, and low, exuding a sense of dynamism even when it's standing still. The L-shaped taillights at the rear add a touch of sophistication, and the dual exhaust tips hint at the power lurking beneath. Every line and curve on the 640i Gran Coupe seems intentional, contributing to an overall aesthetic that is both timeless and modern. Unlike some of its more angular competitors, the 6 Series Gran Coupe offers a softer, more fluid design that appeals to a broader audience looking for understated luxury and performance. The wheels are also a significant design element, typically large and intricately styled, further enhancing the car's athletic stance. When you see this car on the road, it commands attention without being ostentatious. It’s the kind of vehicle that suggests discerning taste and an appreciation for fine automotive engineering. The paint options available for the 2018 model year also played a role in its appeal, with a range of sophisticated metallic and solid colors that highlight the car's sculpted bodywork. The door handles are flush-mounted, adding to the smooth, uninterrupted lines of the body. Even the side mirrors are aerodynamically shaped and visually appealing. For those who appreciate automotive design, the 2018 BMW 640i Gran Coupe is a masterclass in blending sportiness with practicality. It’s a car that looks good from every angle, a true testament to BMW's design philosophy during that era. The overall impression is one of sophisticated power and refined luxury, making it a highly desirable vehicle for anyone seeking a premium four-door coupe experience. It's definitely a car that stands the test of time visually, and that's a big win in the competitive luxury segment. The attention to detail, from the chrome accents to the subtle creases in the bodywork, all contribute to its premium feel and sophisticated appearance. It’s more than just a car; it’s rolling sculpture.

Interior Comfort and Tech

Slide inside the 2018 BMW 6 Series 640i Gran Coupe, and you're immediately enveloped in a world of luxury and cutting-edge technology. BMW has always been known for its driver-focused cockpits, and this car is no exception. The materials used are top-notch – think supple Nappa leather, real wood or aluminum trim, and soft-touch surfaces everywhere you look. The seats are incredibly comfortable, offering excellent support for both short commutes and long road trips. They're usually heated, and often ventilated and massaging options are available, making every drive a first-class experience. The dashboard is elegantly laid out, with the driver firmly in mind. The instrument cluster is clear and easy to read, and the central infotainment screen, controlled by BMW's iDrive system, is intuitive and responsive. For 2018, the iDrive system was quite advanced, featuring navigation, Bluetooth connectivity, a premium sound system (often Harman Kardon or Bang & Olufsen), and smartphone integration. While it might not have the massive, flashy screens of today's cars, it was sophisticated for its time and remains perfectly functional and user-friendly. The ambient lighting options allow you to customize the cabin's mood, adding another layer of luxury. The rear seats, while perhaps not as spacious as a traditional sedan due to the coupe-like roofline, are still surprisingly accommodating for two adults, offering decent legroom and headroom. Getting in and out of the back is also made easier by the four doors, a key advantage of the Gran Coupe design. Practicality isn't forgotten either; there's a decent-sized trunk that can handle your luggage for weekend getaways. The build quality is exceptional, with tight panel gaps and a solid, refined feel to every button and switch. You'll find thoughtful touches throughout, like the cup holders that are cleverly integrated and the ample storage compartments. The steering wheel is usually a leather-wrapped, multi-function unit that feels great in your hands and provides easy access to audio, cruise control, and phone functions. The overall ambiance inside the 2018 640i Gran Coupe is one of refined opulence and sophisticated technology, creating a sanctuary from the outside world. It’s a place where you can truly enjoy the journey, surrounded by premium materials and thoughtful design. The attention to detail in the interior design is evident, from the stitching on the leather to the precise fit and finish of the trim pieces. It truly feels like a bespoke environment tailored for the discerning driver and passengers. It’s a testament to BMW’s commitment to luxury and comfort, ensuring that every aspect of the driving experience is elevated.

Performance and Driving Dynamics

Under the hood, the 2018 BMW 6 Series 640i Gran Coupe packs a serious punch, making it as exhilarating to drive as it is luxurious to be in. The '640i' designation tells us it's powered by BMW's renowned 3.0-liter turbocharged inline-six engine. This powerhouse delivers a healthy output, typically around 315 horsepower and 330 lb-ft of torque. But it's not just about the numbers; it's about how that power is delivered. The engine is incredibly smooth, refined, and responsive, providing instant acceleration when you need it. Whether you're merging onto the highway, overtaking slower traffic, or just enjoying a spirited drive on a winding road, the 640i Gran Coupe handles it with effortless grace. This power is sent to the rear wheels (or optionally to all four wheels with BMW's xDrive all-wheel-drive system) through an 8-speed Steptronic automatic transmission. This transmission is a gem – it shifts quickly and smoothly, often imperceptibly, but can also be commanded for rapid shifts in sport mode. The driving dynamics are where the 6 Series truly shines. BMW's suspension tuning strikes a brilliant balance between comfort and sportiness. The ride is compliant enough to soak up road imperfections, ensuring a comfortable experience for passengers, yet it remains firm and controlled when you push the car. The steering is precise and communicative, giving you a good feel for what the front wheels are doing. In corners, the Gran Coupe feels planted and confident, with minimal body roll, thanks to its low center of gravity and sophisticated suspension setup. The optional adaptive suspension further enhances this, allowing you to tailor the car's handling characteristics to your preference. Braking performance is equally impressive, with strong, reliable stopping power from the performance-oriented brakes. Driving the 2018 640i Gran Coupe is an engaging experience. It feels substantial and well-planted on the road, offering a sense of security and stability at higher speeds. The inline-six engine has a satisfying growl when you accelerate, and the overall refinement of the powertrain means that even during spirited driving, the experience remains sophisticated and comfortable. It’s the kind of car that can easily transition from a relaxed cruiser to a sporty GT car at the flick of a switch. The combination of a potent engine, a sophisticated transmission, and finely tuned chassis makes the 640i Gran Coupe a truly rewarding car to drive. It’s a testament to BMW's engineering prowess, delivering a driving experience that is both exciting and refined, fulfilling the promise of a true German luxury performance car. The optional M Sport package often enhances these dynamics even further with sportier suspension tuning and aerodynamic enhancements.

Technology and Safety Features

Beyond the luxury and performance, the 2018 BMW 6 Series 640i Gran Coupe is also equipped with a suite of advanced technology and safety features that enhance both convenience and peace of mind. As mentioned earlier, the iDrive infotainment system was a benchmark for its time. It provided access to navigation, entertainment, vehicle settings, and communication functions through a high-resolution central display and the intuitive rotary controller on the center console. For 2018, it likely included features like enhanced Bluetooth with audio streaming, USB ports, and possibly even Wi-Fi hotspot capability depending on the specific options. The audio systems were typically premium, with brands like Harman Kardon or Bang & Olufsen offering immersive sound quality. Driver assistance systems were also becoming more prevalent, and the 640i Gran Coupe was available with features like adaptive cruise control with stop-and-go functionality, lane departure warning, blind-spot monitoring, and a rearview camera with surround-view options. These systems work collaboratively to help prevent accidents and reduce driver fatigue, especially on long journeys. Parking assistance was also a highlight, with parking sensors all around and available automatic parking systems. The headlights were usually adaptive LED units, which illuminate the road better and can automatically adjust their beams to avoid dazzling other drivers. The keyless entry and start system added to the convenience, allowing you to access and drive the car without fumbling for keys. The head-up display (HUD) was another desirable feature, projecting important driving information like speed, navigation prompts, and warnings directly onto the windshield in the driver's line of sight, minimizing the need to look away from the road. Safety was paramount, and the 6 Series Gran Coupe was built with a robust structure designed to protect occupants in the event of a collision. It also came equipped with a comprehensive array of airbags, advanced anti-lock braking systems (ABS), stability control (DSC), and traction control (DTC). The overall integration of technology in the 2018 640i Gran Coupe was seamless, aiming to enhance the driving experience without overwhelming the user. It represented a significant step forward in automotive technology, blending luxury, performance, and safety in a package that was both sophisticated and forward-thinking. These features collectively contribute to making the 640i Gran Coupe not just a beautiful and powerful car, but also a safe and technologically advanced one, ensuring a premium experience for everyone inside.

Why the 2018 640i Gran Coupe Stands Out

So, what makes the 2018 BMW 6 Series 640i Gran Coupe a compelling choice, even years after its release? It’s the unique blend of attributes that BMW managed to pack into one car. Firstly, it's the design. As we've discussed, it's a stunning piece of automotive art, offering the sleek lines of a coupe with the everyday usability of four doors. This combination is rare and executed beautifully, setting it apart from more conventional sedans and coupes. Secondly, the performance. The turbocharged inline-six engine provides more than enough power for spirited driving, coupled with BMW's legendary driving dynamics. It offers a thrilling yet comfortable ride, making it a true grand tourer – capable of crossing continents in style and comfort, or carving up canyon roads with enthusiasm. Thirdly, the interior. The cabin is a masterclass in luxury, comfort, and technology. The high-quality materials, ergonomic design, and advanced (for its time) infotainment and safety features create an environment that is both enjoyable and secure. It feels special every time you get in. Fourthly, it represents value in the used car market. While new, it was a premium-priced vehicle, but today, it offers a substantial amount of luxury, performance, and style for the money compared to newer models. You get a lot of car for your dollar. Finally, it’s a car that offers exclusivity. While the 5 Series and 7 Series were more common, the 6 Series Gran Coupe always felt a bit more special, a bit more niche, appealing to those who wanted something a little different. It's a car for those who appreciate sophisticated engineering, timeless design, and a driving experience that engages the senses. It’s not just another luxury car; it’s a statement of individuality and refined taste. The 2018 BMW 640i Gran Coupe remains a fantastic option for anyone looking for a stylish, comfortable, and dynamically capable luxury vehicle that offers a unique blend of coupe aesthetics and sedan practicality. It’s a car that truly delivers on multiple fronts, making it a standout in its segment.

Conclusion

In conclusion, the 2018 BMW 6 Series 640i Gran Coupe is a remarkable automobile that masterfully blends elegant styling, luxurious comfort, and exhilarating performance. It’s a car that appeals to those who appreciate the finer things in life but also demand a dynamic driving experience. Whether you're drawn to its sophisticated exterior design, the meticulously crafted interior, or the potent yet refined powertrain, the 640i Gran Coupe delivers on all fronts. It represents a sweet spot in the automotive market, offering the practicality of four doors within the alluring silhouette of a coupe, all wrapped up in BMW's signature quality and engineering excellence.
