G16 · 8 Gran Coupe

What the BMW G16 Is

The BMW G16 is the elegant four-door Gran Coupe variant of the modern 8 Series line, produced from 2020 through 2026. Stretched over a longer wheelbase than its two-door G15 coupe and G14 convertible siblings, the G16 delivers rear-seat space for a family alongside the low, wide, dramatic proportions that define BMW's flagship coupe range. It sits at the top of BMW's grand-touring hierarchy, positioned as a rival to the Mercedes-Benz CLS and Porsche Panamera.

Every G16 rides on BMW's CLAR platform, sharing engineering DNA with the larger 7 Series and 5 Series. You can confirm any car's exact build details with our VIN decoder, and explore how the 8 Series fits BMW's lineage in our BMW DNA overview.

The Models & Body Styles

In the US market, the G16 Gran Coupe was offered in four distinct configurations:

• 840i Gran Coupe — rear-drive, inline-six entry point
• 840i xDrive Gran Coupe — all-wheel-drive six-cylinder
• M850i xDrive Gran Coupe — the V8-powered performance flagship
• ALPINA B8 Gran Coupe — the bespoke, uprated ALPINA interpretation

All four share the same four-door Gran Coupe silhouette, differentiating themselves through powertrain, suspension tuning and trim rather than body style.

Engines & Drivetrains

The 840i models use BMW's smooth, torque-rich B58 3.0-liter turbocharged inline-six, available in rear-wheel drive or with xDrive all-wheel drive. The M850i xDrive and ALPINA B8 step up to the N63-family 4.4-liter twin-turbo V8, with the ALPINA extracting even more output and pairing it with unique ZF eight-speed calibration and chassis tuning. Every G16 uses BMW's eight-speed automatic, and the V8 cars are xDrive-only.

Ownership & Buying Notes

The G16 is a mature, well-sorted platform that rewards buyers seeking flagship comfort with usable rear seating. The B58-powered 840i models offer the best long-term value and running costs, while the V8 cars deliver serious pace at higher fuel and maintenance expense. Prospective buyers should verify service history, confirm optional equipment via VIN, and budget for premium tires and brakes on the M850i and ALPINA variants.

Enthusiasts drawn to BMW's grand-touring heritage may also appreciate earlier coupe flagships like the E63 6 Series and the V12 E65 7 Series, both spiritual predecessors to the 8 Series philosophy.
