Operator notes
G16 (8 Series Gran Coupe) based, 4.4L twin-turbo V8 (~613 hp), ZF 8HP ALPINA calibration. Final model year 2025 (no 2026 MY); last true Buchloe-built ALPINA before full BMW integration - 8 Series line ends ~April 2026. Relatively new so long-term data limited; expect shared 4.4L V8 issues. Timing CHAIN. Time-based service advised.
When the smart money sells
On fleet math, a gas ALPINA B8 Gran Coupe retires around 95,000 miles - but the exit window opens earlier here: Hot-V coolant / turbo oil leaks risk window ($1,500-$4,000) opens ~50,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
