2026 BMW 8 Series Specs

V8 Power & The "Edition M Heritage".

For the 2026 model year, the specification sheet of the BMW 8 Series reads like a love letter to the internal combustion era. With production scheduled to end in April 2026, this is likely the final opportunity to secure a brand-new BMW Grand Tourer powered by a non-hybrid V8 engine.

Knoxville drivers aren't just looking for transportation; they are looking for provenance. The 2026 8 Series delivers this through the limited-run Edition M Heritage, the sheer thrust of the N63 V8, and the preservation of a driver-focused cockpit. At Grayson BMW, we have compiled the definitive technical data to help you choose your future classic.
Engine Architecture: The Final V8s.

The headline for 2026 is the retention of pure combustion power. Unlike competitors downsizing to V6 hybrids, the 8 Series maintains its cylinder count.
M850i xDrive: The N63 V8.

The M850i is powered by the N63 4.4-liter TwinPower Turbo V8. This "hot-vee" design places the turbochargers inside the cylinder bank for immediate response.

  • Horsepower: 523 hp @ 5,500-6,000 rpm
  • Torque: 553 lb-ft @ 1,800-4,600 rpm
  • 0-60 MPH: 3.6 seconds (Coupe/Gran Coupe)
ALPINA B8: The Refined Titan.

The ALPINA B8 takes the V8 architecture and modifies it for "effortless speed." It features specific turbochargers, intercoolers, and exhaust tuning unique to Buchloe, Germany.

  • Horsepower: 612 hp @ 5,500 rpm
  • Torque: 590 lb-ft @ 2,000 rpm
  • 0-60 MPH: 3.3 seconds
  • Top Speed: 201 mph
840i: The B58 Inline-6.

For those who value balance over brute force, the 840i utilizes the B58 3.0-liter inline-6.

  • Horsepower: 335 hp @ 5,000 rpm
  • Torque: 368 lb-ft @ 1,600 rpm
  • 0-60 MPH: 4.7 seconds (RWD) / 4.4 seconds (xDrive)

Special Feature: The 2026 "Edition M Heritage".

To celebrate the end of the 8 Series lineage, BMW has released the M850i xDrive Gran Coupe Edition M Heritage. This limited model draws directly from the paint palette of the original E31 8 Series (1990-1999).

Exclusive Heritage Colors:

  • Mauritius Blue Metallic (Code 287)
  • Oxford Green Metallic (Code 324)
  • Daytona Violet Metallic
  • Bright Red (Hellrot)

These vehicles also feature a standard M Carbon Fiber roof with tri-color M stripes, a detail previously reserved for the M4 CSL.

Interior Tech: The "Classic Cockpit" Advantage.

While the 3 Series and Z4 have moved to the widescreen iDrive 8.5 system, the 2026 8 Series deliberately retains iDrive 7 and the "Live Cockpit Professional" layout.

Why This Matters to Enthusiasts:

  • Physical Buttons: You get dedicated, tactile buttons for heated seats, fan speed, and memory presets.
  • Glass Controls: The optional "CraftedClarity" glass gear selector features a laser-etched "8" that glows at night, adding a jewelry-like quality to the center console.
  • Driver Focus: The 12.3-inch central display is integrated into the dash rather than floating, maintaining the classic sports car "cockpit" feel.

Dimensions & Practicality.

The 8 Series Gran Coupe surprises with its usability. It is 9 inches longer than the Coupe, providing genuine legroom for two rear passengers.

  • Trunk Capacity: 15.5 cubic feet (Gran Coupe), which is enough for three golf bags.
  • Wheelbase: 119.0 inches (Gran Coupe) vs 111.1 inches (Coupe), which is creating a smoother highway ride for Knoxville commuters.
Secure Your Piece of History.

The window to order a 2026 BMW 8 Series with the "Edition M Heritage" specs or a custom Individual color is closing. Once production ends in April 2026, these specs will effectively become "unobtainium".
