BMW 6 Series G32 (2017–): a different format if the 5 feels tight

BMW 6 Series G32 is not a “sporty six” in the usual sense, but a large five-door liftback for those who have outgrown the 5 Series but don’t yet need a crossover or a 7 Series. Its idea is simple: a very spacious second row, a large trunk, quiet highway cruising, and a comfort-focused suspension with rear air springs as part of the model’s core concept.

The G32 suits best those who drive a lot between cities, carry a family, or regularly use the trunk. It fits worse for those who expect compact BMW agility, easy city parking, and lower running costs.

The model and its place in the market

In the market, the BMW 6 Series G32 sat between the practical 5 Series and more expensive executive models. Formally it’s a liftback, but in terms of space and use case it’s closer to a big long-distance car: a high roofline, a long wheelbase, proper rear seating for three adults, and a trunk that genuinely works for family trips.

Its purpose is not design for design’s sake, but a blend of comfort and capacity. Compared with classic BMW sedans, the G32 is less engaging, but more convenient as a daily car—especially when you need quietness, extra room, and proper access to the trunk.

Generations and model history

The BMW 6 Series GT had one generation—G32. The model debuted in 2017, sales started at the end of the same year, and production ended in August 2023. Essentially, it develops the idea of previous large BMWs in the GT body format, but on a newer architecture related to the 5 Series.

The 2021 model-year update brought less of a character change and more technical refinement: a 48-volt mild hybrid appeared on most versions, equipment and the lineup structure were revised. Importantly, these are not separate generations, but one model with pre-facelift and updated phases.

Engines and transmissions

Depending on year and market, the range differed. In the updated phase, the choice looked logical: 2.0-liter gasoline and diesel for calmer daily driving, and inline 3.0-liter “sixes” for those who want effortless torque reserves. All versions had an 8-speed automatic transmission; drive was rear-wheel or xDrive all-wheel depending on the modification.

If you want the best highway all-rounder, 630d and 630d xDrive look the most rational: lots of torque, good flexibility, and more moderate consumption. The 640i is more appealing in throttle response and sound, but in real life it uses noticeably more. The 620d and 630i are for those who prioritize relaxed ownership and lower fuel and service costs.

After the 2021 update, these versions received a 48-volt mild hybrid with a starter-generator. That doesn’t make the G32 a “hybrid” in everyday terms, but it adds smoother take-offs, a gentler start-stop operation, and a small assist in city driving.

Body, dimensions, and chassis

The main technical idea of the G32 is a large body without the typical downsides of a heavy wagon. It features a long 3070 mm wheelbase, a higher-than-class seating position, a fifth door instead of a conventional trunk lid, and a rear self-leveling air suspension. On rough roads you can really feel it: the car doesn’t seem low, and it doesn’t react as nervously to load.

Its dimensions are large, so in a tight city you’ll need to adapt. But on the highway that length translates into stability and comfort. Trunk volume has a nuance: later European data lists 600–1800 L, while at launch BMW stated 610 L. For an owner, the difference isn’t critical—the trunk is large either way and especially practical thanks to the liftback format.

Interior, comfort, and safety

The interior is exactly why the G32 exists. In the back it’s not just “reasonably spacious”—there’s genuinely plenty of room for legs, head, and shoulders, and the second row is designed for three adults without the feel of a cramped bench. Entry and exit are easier than in lower sedans, and the cabin is set up for long trips without fatigue.

Comfort is the model’s strong suit. On the highway, the BMW 6 Series G32 is quiet, holds speed well, and doesn’t pepper the cabin with small impacts. But there’s a flip side: visibility isn’t exemplary; thick pillars and the car’s size make you rely more often on cameras and parking sensors, and in some configurations owners mention wind noise due to the large sunroof and frameless doors.

In terms of safety, the model is strong even by today’s standards: in Euro NCAP tests it posted high results for adult and child protection. In everyday terms, that means not only a solid body, but also a proper set of assistants, including automatic emergency braking and detection of other road users.

Everyday use

In daily use, the G32 shows its best not in the city center but on long routes. For a family it’s more convenient than many business-class sedans: the trunk is wide, the loading opening is large, the suspension calmly handles rough asphalt, and the ground clearance can be adjusted a bit. If most trips are short urban runs with underground parking, the body length and turning circle will quickly make themselves known.

For fuel consumption, it’s worth looking beyond the brochure. Diesels make more sense in this model for high mileages, while the gasoline 640i in real life can easily go far beyond calm official figures if you drive actively or spend a lot of time in city traffic. For a used car, service history, the condition of the electronics and braking system, and components related to diesel emissions equipment are critically important.

Strengths and weaknesses

From an owner’s perspective, the BMW 6 Series G32 is about getting the priorities right. It’s very strong where space, comfort, and highway torque matter, but weaker where people expect the lightness and sharpness of a classic BMW sedan.

Who the G32 suits: those who want one big car for highways, family life, business trips, and long-distance travel. Who it doesn’t suit: those who prefer a short body, sharp steering, cheaper maintenance, or simply don’t accept the very format of a tall liftback.

Tuning and accessories

For the BMW 6 Series G32, the smartest tuning is practical rather than showy. This model already covers comfort well from the factory, so owners more often refine interior and body protection than try to make it more aggressive than it really is. The full catalog for the model is available at /tyuning-bmw-6-seriya-g32-2017-gg.html.

If the car is driven every day, it makes sense to focus on items that truly reduce wear and make life easier: mats for the large cabin, mud flaps to protect the lower body, and for travel—solutions for carrying extra luggage. Exterior styling exists too, but on the G32 restrained upgrades work better without overloading the look.

• Catalog for BMW 6 Series G32 — a quick way to see model-compatible solutions without random items.
• Floor mats — a basic must-have for a large cabin, especially if the car often does highway driving, winter use, or carries passengers in the second row.
• Mud flaps — help reduce sandblasting on the sills, the lower door sections, and the arches on a long, heavy body.

Conclusion

The BMW 6 Series G32 (2017–2023) is a rare large-liftback format that genuinely makes sense in real use. It’s not as sharp to drive as classic BMW sedans, but it delivers what they often lack: lots of rear space, a very practical trunk, and high comfort on long routes.

If you look at the model realistically, its strongest role is a fast family highway car rather than an emotional toy. In that scenario, the G32 justifies its size and format. This material is based on real selection experience, practical know-how, and real usage scenarios, so the main takeaway is simple: the G32 is worth choosing for those who understand exactly what they’re paying for—capacity, quietness, and long-distance comfort.
