Powertrain families
N55B30T0 · S55B30T0
2016–2021

M2 → F87 → Coupe
How this generation came about, what made it different and how the selected coupe fits into the family.
F87 established M2 as BMW M's compact rear-wheel-drive coupé in 2016. It paired the short 2 Series body with wider axles and major chassis components related to the contemporary M3/M4, while retaining a six-speed manual option alongside the seven-speed dual-clutch transmission.
The original M2 used an N55-derived turbo inline-six; the 2018 M2 Competition changed to the M-developed S55 and brought cooling, braking, structure and seat revisions. The limited M2 CS then raised performance again with adaptive suspension and extensive CFRP, so base, Competition and CS need separate technical rows.
Outputs and dates differ by market and model year, and the US rated the same engines under SAE rather than metric horsepower. The M Performance parts catalogue and the M2 CS Racing are not production trim levels and must remain outside the road-car modification table.
Dimensions can change with body, market and model year, so this page keeps them tied to the exact factory branch.
| Body | Code | Production | Doors / seats | Length | Luggage |
|---|---|---|---|---|---|
| Coupe | F87 | 2016–2021 | 2-door coupe / 4 | 4,468 mm | 390 L |
The generation could span very different engines and drivetrains. The table keeps output, gearbox, market and production period together.
Documented coupe applications; output and availability remain market- and model-year-specific.
| Model | Years | Engine | Output | Transmission | Drive | Market | Source |
|---|---|---|---|---|---|---|---|
| M2 | 2016–2018 | N55B30T0 turbo inline-six | 370 PS | 6MT / 7DCT | RWD | Global range | BMW M2 F87 and M2 Competition |
| M2 Competition | 2018–2021 | S55B30T0 twin-turbo inline-six | 410 PS / 405 hp US | 6MT / 7DCT | RWD | Global range | BMW M2 F87 and M2 Competition |
| M2 CS | 2020–2021 | S55B30T0 twin-turbo inline-six | 450 PS / 444 hp US | 6MT / 7DCT | RWD | Global range | The BMW M2 CS F87 |

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-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.
The N55-powered rear-drive coupé entered production with manual and DCT choices.
S55 power, revised cooling and extensive chassis changes replaced the original specification.
The limited CS added more power, adaptive dampers, weight reduction and track-focused equipment.
The first M2 family left production after close to 60,000 global sales.
Performance models, option packages and regional editions may look related, but their engineering and production identity can be very different.
M2 F87 is a distinct F87 body branch. A lower-roof two-door body with longer doors and a more overtly sporting brief than the corresponding sedan. Engines/drive: N55B30T0, S55B30T0.
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.
