Powertrain families
S38B36 · S38B38
1988–1995

M5 → E34 → Touring
How this generation came about, what made it different and how the selected touring fits into the family.
E34 developed M5 into a more mature sedan and, from 1992, the first M5 Touring. Early cars used the 3.6-litre S38B36; the later 3.8-litre S38B38 brought more power and accompanying chassis changes, while North America retained a distinct 3.6-litre market programme.
Sedan and Touring have different production windows and totals. The Touring was left-hand drive only and extremely low volume; late six-speed cars, Nürburgring package equipment and market editions must be attached to build date and region.
E34s were largely hand-finished by BMW M, but factory and assembly details changed through the cycle. The one-off convertible prototype is documented history, not a production body and must not create a public catalog route.
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 touring applications; output and availability remain market- and model-year-specific.
| Model | Years | Engine | Output | Transmission | Drive | Market | Source |
|---|---|---|---|---|---|---|---|
| M5 3.8 | 1991–1995 | S38B38 inline-six | 340 PS | 5MT / 6MT | RWD | Europe | The BMW M5 E34 |

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.
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 3.6-litre E34 sedan entered production.
European displacement grew and the first series M5 wagon joined the range.
Late cars adopted a six-speed manual alongside other final-cycle revisions.
Sedan and Touring production concluded after different run lengths.
Performance models, option packages and regional editions may look related, but their engineering and production identity can be very different.
M5 E34 is a distinct E34 body branch. The conventional four-door passenger-car body, balancing rear-seat access, luggage space and the generation’s core chassis layout. Engines/drive: S38B36, S38B38.
M5 E34 Touring is a distinct E34 body branch. The long-roof estate body adds a large rear opening and folding load area while retaining the passenger-car platform. Engines/drive: S38B36, S38B38.
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.
