S68B44T0 V8 · Gen5 plug-in-hybrid eDrive
2024–present

M5 → G90/G99 → Sedan
How this generation came about, what made it different and how the selected sedan fits into the family.
G90/G99 is the first plug-in-hybrid M5 generation. Its M HYBRID system combines the S68 V8 with an electric motor integrated into the eight-speed transmission, a high-voltage battery and M xDrive; system output must not be confused with the combustion engine's standalone rating.
G90 Sedan and G99 Touring launched together as one technical family but have distinct bodies, mass, luggage volume and market availability. Electric range, charging time and consumption depend on homologation cycle and usable battery definition and must be labelled by market.
The substantial mass increase is part of the generation's engineering context, not a transcription error. Performance, battery state and test method are related, so acceleration and consumption claims require their factory test conditions rather than comparison as naked numbers with F90.
Dimensions can change with body, market and model year, so this page keeps them tied to the exact factory branch.
The generation could span very different engines and drivetrains. The table keeps output, gearbox, market and production period together.
Documented sedan applications; output and availability remain market- and model-year-specific.
| Model | Years | Engine | Output | Transmission | Drive | Market | Source |
|---|---|---|---|---|---|---|---|
| M5 Sedan | 2024–present | S68B44T0 V8 + Gen5 electric motor | 727 PS / 717 hp system | 8AT M Hybrid | M xDrive | Global range | The all-new BMW M5 |

Engine, cooling, exhaust, software and transmission form a distinct M or ALPINA specification rather than an option package on the base model.
Where diesels were offered, output, injection generation and emissions hardware are recorded market by market.
Mild- and plug-in hybrids are separate derivatives; combustion-engine output must not be substituted for total system output.
Gearboxes, driven wheels and final-drive hardware changed with engine, market and production date.
Gearbox type and unit code follow engine, market and production date. Gear count alone does not identify the transmission.
Catalog architecture: BMW M · longitudinal layout · rear- or all-wheel drive. All-wheel-drive availability and hardware remain derivative-specific.
Ratio, differential type and electronic control belong to the exact derivative and can differ on performance models.
Suspension, brakes, safety systems and electronics evolved across the range, even when cars shared the same basic architecture.
The important launches, additions and updates did not always happen at the same time for every body or market.
BMW announced the first M HYBRID production M5.
Series production of the sedan began at the 5 Series plant.
The wagon body returned with the same plug-in-hybrid performance concept.
Sedan and Touring rollout began with region-specific timing and homologation.
Performance models, option packages and regional editions may look related, but their engineering and production identity can be very different.
M5 G90 is a distinct G90/G99 body branch. The conventional four-door passenger-car body, balancing rear-seat access, luggage space and the generation’s core chassis layout. Engines/drive: S68B44T0 V8, Gen5 plug-in-hybrid eDrive.
M5 G99 is a distinct G90/G99 body branch. The long-roof estate body adds a large rear opening and folding load area while retaining the passenger-car platform. Engines/drive: S68B44T0 V8, Gen5 plug-in-hybrid eDrive.
Cabin technology and standard equipment changed by country and year; a build sheet remains the best guide to one individual car.
A practical starting point for inspecting and maintaining a car from this generation — not a diagnosis of an individual example.
| Item | Interval / trigger | Catalog note |
|---|---|---|
| Engine oil & filter | CBS/factory schedule; time and mileage for historic cars | Oil approval follows the exact engine and market. |
| Brake fluid | Time-based factory schedule | ABS/DSC-compatible bleeding procedure is required after hydraulic work. |
| Coolant | Factory schedule and condition | Fluid specification and bleeding method are generation-specific. |
| Transmission & final drives | Unit type and operating conditions | Use the exact approved fluid; no one interval fits every derivative. |
The badge and registration year tell only part of the story; production date, body code, engine and factory options complete it.
The story is mapped through English Wikipedia and its bibliography, then important dates and technical claims are checked against BMW material.
