The design language alone is enough to make you fall in love, but when you combine that with the engineering prowess BMW is known for, you get something truly exceptional.

Under the Hood: Power and Performance

Let's get down to the nitty-gritty, guys, because the heart of any performance car is what's under the hood, right? The 2018 BMW 6 Series 640i Gran Coupe packs a punch that will leave you grinning from ear to ear. We're talking about a 3.0-liter turbocharged inline-six engine. Now, don't let the 'six' fool you; this thing is a beast. It's tuned to deliver a stout 315 horsepower and a healthy 330 lb-ft of torque. This power is sent to the rear wheels (or available xDrive all-wheel drive if you opted for it) through an 8-speed Steptronic automatic transmission. This transmission is smooth as butter but also incredibly responsive when you want to put the hammer down. Think of it like this: it can glide you through traffic like a dream, but when the road opens up, it shifts with lightning speed, keeping you firmly in the power band.

What does all this mean for you on the road? Well, it translates into some seriously impressive acceleration. We're talking 0 to 60 mph in just around 5.3 seconds for the rear-wheel-drive model. If you go for the xDrive version, you might shave off a tenth or two. That's supercar-quick territory, my friends! But it's not just about straight-line speed. BMW is renowned for its driving dynamics, and the 640i Gran Coupe is no exception. The steering is precise and communicative, giving you confidence to take on corners with enthusiasm. The suspension strikes a fantastic balance between sporty handling and comfortable ride quality. You get that engaging feel that BMW drivers love, but it's also refined enough for long highway cruises. The turbocharged engine provides ample power for passing maneuvers, merging onto highways, and just generally making driving feel effortless and fun. It's the kind of power delivery that feels immediate and rewarding, with a satisfying growl when you really push it. Plus, for a car with this much performance, the fuel economy is actually quite respectable, thanks to the efficient turbocharging and the well-matched 8-speed gearbox. It’s a perfect blend of everyday usability and exhilarating performance.

Exterior Design: A Masterpiece of Style

Now, let's talk about looks, because let's be honest, the 2018 BMW 6 Series 640i Gran Coupe is a stunner. BMW really hit it out of the park with the Gran Coupe design. It takes the sporty appeal of a coupe and injects it with the practicality of four doors, all while maintaining an incredibly elegant and flowing silhouette. The long hood, the short front overhang, the raked windshield, and the dramatically sloping roofline – it all comes together to create a truly breathtaking profile. It looks like it's moving even when it's standing still. The front fascia is classic BMW, with the signature kidney grilles and sleek, aggressive headlights that give it a determined stare. Down the side, the character lines are subtle but effective, emphasizing the car's length and muscular stance. The frameless doors add a touch of exotic flair, and when they're open, they just scream 'premium'.

But the real magic happens at the rear. The roofline tapers down elegantly, leading to a sculpted rear end with sophisticated LED taillights. It’s a design that manages to be both sporty and sophisticated, avoiding the overly aggressive or boy-racer look. Instead, it exudes a sense of refined power and understated luxury. The Gran Coupe designation means it's longer and offers more rear-seat space than a traditional coupe, but BMW’s designers did such a masterful job that it doesn’t look bloated. It maintains its athletic proportions perfectly. This car commands attention without being flashy. It's the kind of vehicle that gets admiring glances because of its pure design elegance and proportions, not because of gaudy styling cues. The wheel designs offered also complement the overall look beautifully, adding to the car's premium feel. Whether you're pulling up to a fancy restaurant or just cruising down the boulevard, the 640i Gran Coupe makes a powerful and stylish statement about your appreciation for automotive artistry. It’s a design that has aged incredibly well, looking just as relevant and desirable today as it did when it first rolled off the production line. It truly is a car that you can fall in love with just by looking at it.

Interior Comfort and Luxury

Stepping inside the 2018 BMW 6 Series 640i Gran Coupe is like entering your own private sanctuary, guys. BMW interiors are famous for their driver-focused design and high-quality materials, and this car is a prime example. From the moment you sit down, you're surrounded by premium leather, real wood trim, and soft-touch surfaces everywhere you look and feel. The seats are where BMW truly shines. The front seats are incredibly comfortable and supportive, with a wealth of adjustments (often 14-way or more, including lumbar and bolster) to find your perfect driving position. They're heated as standard, and ventilated or massaging functions might be available on higher trims or as options. Long road trips? No problem. Your back will thank you. The driving position is commanding, giving you a great view of the road ahead and all the controls.

Speaking of controls, BMW's iDrive infotainment system is your command center. It's known for its intuitive rotary dial controller, located conveniently on the center console, which makes navigating menus easy and safe while driving. The screen itself is crisp and clear, displaying navigation, audio, phone, and vehicle settings. While the 2018 model might not have the absolute latest, largest screens of today's cars, it was cutting-edge for its time and remains highly functional and user-friendly. The cabin is also exceptionally quiet, thanks to excellent sound deadening. You can have a conversation at highway speeds without raising your voice, or simply enjoy your music or the engine's subtle soundtrack. The rear seats, while not as spacious as a full-size sedan due to the sloping roofline, are still quite usable for adults, especially on shorter journeys. The 'Gran Coupe' aspect really comes into play here, offering more headroom and legroom than you'd expect in a car that looks this sporty. Ambient lighting adds a touch of sophistication, especially at night, creating a warm and inviting atmosphere. The overall impression is one of understated luxury and meticulous craftsmanship. It’s a place where you’ll want to spend time, whether you're commuting to work or embarking on a cross-country adventure. The build quality is superb, with tight panel gaps and solid-feeling switchgear that exudes durability and refinement.

Technology and Safety Features

In the 2018 BMW 6 Series 640i Gran Coupe, you're not just getting a stylish and powerful car; you're getting a smart and safe one too, guys. BMW equips this Gran Coupe with a solid array of technology and driver-assistance features to enhance your driving experience and provide peace of mind. The centerpiece of the infotainment system is the iDrive interface, which, as we mentioned, is controlled via a rotary knob and buttons on the center console, along with direct screen input. It provides access to navigation, Bluetooth connectivity for calls and audio streaming, a premium sound system (often Harman Kardon or Bang & Olufsen if optioned), and various vehicle settings. While it might not have Apple CarPlay or Android Auto as standard on all 2018 models (this varied by production date and options), the system is still very capable and integrates well with your smartphone.

Beyond entertainment, the 2018 6 Series Gran Coupe was available with a suite of advanced safety technologies. Depending on the specific options selected, you could find features like Adaptive Cruise Control with stop-and-go functionality, which can automatically maintain a set distance from the car in front. Lane Departure Warning alerts you if you drift out of your lane, and Blind Spot Detection warns you of vehicles in your blind spots, making lane changes much safer. Parking Assistant could even help guide the car into parking spaces. Other available safety features included a Surround View camera system for a 360-degree view around the vehicle, which is incredibly helpful for maneuvering in tight spots. Forward Collision Warning with Pedestrian Detection and Automatic Emergency Braking could help mitigate or avoid accidents by alerting the driver and applying the brakes if necessary. These systems weren't just passive safety nets; they were active aids designed to help you avoid dangerous situations altogether. The combination of a strong chassis, multiple airbags, and these advanced electronic aids made the 640i Gran Coupe a secure environment for occupants. It’s this blend of cutting-edge tech and robust safety engineering that solidifies the 640i Gran Coupe’s position as a top-tier luxury grand tourer.
