Overview

BMW’s 6 Series luxury grand tourer (GT) was first produced in the 1970s and 1980s. Then there was a long absence until production started up again in 2003, and the current generation has been around since 2011. BMW has been at something of a crossroads with the 6 Series, and it looks as if the model will be replaced for 2019 with another name from the past—the 8 Series. Nevertheless, the company has made a few notable changes for 2018 model year. The exterior comes in a new Sonic Blue color, and the M Sport package now offers new bi-color 20-inch M wheels and carbon-fiber trim lifted from the more hardcore M6. The 2018 6 Series is available in the 640i and 650i trims as a convertible or longer 4-door Gran Coupe and in the luxurious Alpina B6 Gran Coupe trim. The base 640i Gran Coupe starts at just under $80,000, but more loaded models run well into 6-figure territory.
The 6 Series base 640i trim is outfitted with a turbocharged 3.0-liter inline 6-cylinder engine mated to an 8-speed automatic transmission and good for 315 hp and 330 lb-ft of torque. The 640i Gran Coupe can reach 60 mph in a rather quick 5.2 seconds, while the equivalent Convertible variant won’t be too far behind. The 640i will get fuel-economy numbers of 20 mpg city, 29 highway, and 23 combined with rear-wheel drive (RWD) and 19, 28, and 22 with xDrive all-wheel drive (AWD).
The 6 Series 650i and Alpina B6 trims come with a significantly more powerful twin-turbo 4.4-liter V8 engine paired with the same automatic transmission. Its 445 hp and 480 lb-ft are enough to push the vehicle to 60 mph in 4.3 seconds, 1 full second faster than the 640i, but the engine is predictably thirstier. Expect to manage fuel figures of 17, 24, and 19 with the RWD 650i and 15, 24, and 18 with the AWD 650i and Alpina B6 Gran Coupe trims.
While more GT than sports car thanks to its high curb weight, the 6 Series is nevertheless a competent machine on corners, and drivers can choose between Comfort, Sport, and Sport+ settings for adjustments to the steering feel, throttle response, shift timing, and suspension. An available Adaptive Drive system further reduces body roll, and the M Sport Edition package adds 19-inch double-spoke wheels and an aero body kit.
As one would expect, the 6 Series’ interior boasts plenty of comfort and enough high-tech bits to go around. While rear-seat room is tight in the 2-door Convertible, the 4-door Gran Coupe makes good use of its 4.5-inch-longer wheelbase. The Convertible model comes with a folding fabric roof, which is surprising in today’s world of metal hardtops, but it also means it takes up less room when it’s stowed. The top can be raised or lowered in 20 seconds and at speeds up to 25 mph.
As for interior equipment, even the 6 Series’ base 640i trim gets 10-way power-adjustable front seats, wood interior trim, a reversing camera, navigation, a Wi-Fi hotspot, and a 10.2-inch touchscreen with the latest iDrive infotainment system. iDrive houses the navigation system, 3D maps, a 200GB hard drive, and over-the-air map updates. An Executive package adds comfort items like soft-closing automatic doors and front ventilated seats, while the M Sport Edition package adds the same plus an M steering wheel and ceramic controls. A Bang & Olufsen sound system, Apple CarPlay, and a unique wood-inlay steering wheel are other available options.
BMW is an industry leader when it comes to safety, and upper models like the 6 Series are bristling with cutting-edge technology. The 2018 6 Series comes standard with an Active Protection System that pretensions the seat belts, closes the windows, and activates post-collision braking when it determines a collision is imminent. Also standard is an impact sensor system that automatically disconnects the alternator, fuel pump, and starter to prevent a fire; turns on the vehicle’s hazards and interior lights; and unlocks the doors. Other high-tech standard safety features include adaptive cruise control, adaptive brakelights and LED headlights, BMW’s Assist eCall with an SOS button to contact emergency services, and BMW’s Remote Services with a remote door-unlock feature and the My BMW smartphone app. Even with all of this, there are optional extras like lane-departure warning, pedestrian protection, city collision mitigation, active blind-spot detection, and a surround-view camera system.

The 650i is one of the most attractive designs BMW has on the road. Beautiful from every angle. Rides like a Luxury Sedan and corners like a sports car. I will definitely buy another one when this one wears out.

The car has excellent options, carbon fiber trim, active cruise control and B&O sound system. Most 6 series are very good bang for buck considering they generally started at around 100k and are going from 20-40k now. The Audi A7 and S7 are very comparable but the 6 series has them beat in my opinion.

Is the 2018 BMW 6 Series a good car?
Yes — the 2018 BMW 6 Series earns a 4.8/5 user rating, which points to strong owner satisfaction. Owners most often praise its attractive design, strong performance, luxurious ride, and sporty handling, and the model’s roomy cabin and practical hatchback layout make it appealing if you want a luxury car that still works well for everyday use. It also stands out as a distinctive choice if you want style and performance without giving up rear-seat space or cargo flexibility.

Is the 2018 BMW 6 Series reliable?
Owners rate it 4.8/5, a strong signal of long-term satisfaction. Review feedback specifically calls out the 640i model as reliable, dependable, and trouble-free enough that many owners feel confident counting on it over time. That said, the same feedback also flags concerns around certain higher-performance versions, so used buyers should focus on the exact car in front of them rather than the nameplate alone. For long-term ownership, your risk is mostly tied to condition, maintenance history, and how carefully the car was maintained before you buy.
What should I look for when buying a used 2018 BMW 6 Series?
At 55.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important. You should start with a vehicle history report, then prioritize a pre-purchase inspection so you can confirm whether any past damage was repaired properly. Focus your attention on body condition, panel alignment, and signs of inconsistent wear, since those details can tell you more than the listing description alone.
