Euro 7 compliance has already resulted in a concrete power cut for Europe: the 4.4‑liter V8 used in the M5 loses about 41 hp under new emissions limits, a change BMW M is offsetting by increasing electric assistance rather than dropping the engine outright.
What BMW M is doing with its powertrains right now
BMW M’s leadership, represented by CEO Frank van Meel, has stated that the division will continue to offer its signature internal combustion engines — notably the S58 and S68 — so long as market demand exists. The B58 will remain the workhorse in M Performance cars. Practically speaking, that means the road map includes updated inline‑six and V8 units with mild‑hybrid support where regulation forces it, rather than a wholesale switch to pure electric for the high‑performance range.
Key operational notes
- S58 and S68 to continue in core M models; electrification used to meet emissions targets.
- B58 to power M Performance derivatives (e.g., successors to the M340i).
- Some European models see detuning to satisfy Euro 7, balanced by stronger electric motors to retain combined output.
- U.S. market rules are laxer on some emissions, so certain high‑power M models remain unchanged there.
How that affects availability and market logistics
From a distribution and compliance perspective, BMW is choosing a regional approach: adjust powertrain calibration in areas with strict emissions enforcement, keep current specs where regulations allow, and prioritize markets where homologation costs make sense. This is why the M3 Touring was launched only in Europe and select international markets — homologation for the U.S. would be costly because the 3 Series Touring itself was never certified stateside.
Market allocation implications
Allocations are shaped by:
- Regulatory overhead (homologation costs and testing timelines).
- Demand concentration for performance wagons or long‑roof models.
- Production constraints (e.g., carbon roof availability and assembly line limits).
Technical snapshot: engines and likely roles
| Engine | Displacement | Primary Use | Notes |
|---|---|---|---|
| S58 | 3.0 L twin‑turbo I6 | M models (e.g., M3 Competition variants) | Continued use; possible mild‑hybrid additions |
| S68 | 4.4 L V8 | Higher‑end M models (X5 M, X6 M, M5) | Detuned in EU for Euro 7; electric boost keeps combined output |
| B58 | 3.0 L inline‑six | M Performance cars (M340i class) | Stays in lineup for balance of performance and efficiency |
Why BMW won’t rush ICE extinction
BMW cites a global community of buyers who either prefer combustion engines or live in regions where charging infrastructure makes EV ownership impractical. From a logistics angle, keeping ICE variants means existing supply chains, spare parts networks, and familiar maintenance ecosystems remain relevant — a non‑trivial advantage for dealers, rental fleets, and service centers.
M3 Touring: a case study in product and process constraints
The M3 Touring demonstrates the tradeoffs. Mechanically identical to the M3 Competition xDrive, it uses the 3.0‑liter S58 with 503 hp and 479 lb‑ft channeled through an eight‑speed automatic and xDrive. The wagon adds practicality — around 1,500 liters of cargo with seats folded — yet it wasn’t offered in the U.S. due to certification costs. That’s a classic example of how regulatory logistics dictate product availability and route planning for manufacturers and importers.
Design and packaging takeaways
The Touring retains the aggressive M design cues: large kidney grille, carbon fiber accents, quad exhaust, and a functional gurney flap. Production limitations (no carbon roof option) reflect real‑world manufacturing constraints that affect options lists in dealer order banks and rental fleet configurations.
Practical implications for renters and fleet planners
For car rental operators and travelers, these decisions influence fleet composition, insurance and maintenance costs, and inventory planning:
- Regions with stricter emissions may see fewer V8‑powered models available for rental.
- Mild‑hybrid variants change maintenance procedures and parts stocking.
- Touring and long‑roof models can be logistical winners: they offer SUV‑like cargo space while remaining lower profile in urban traffic.
Speaking candidly, I once swapped a compact EV for a B58‑powered long‑roof on a family trip and learned the hard way that range and charging points still matter — nice as the EV was, the flexibility of a gasoline car saved our schedule. As they say, the proof is in the pudding: actual road use often trumps specs on paper.
Summary of likely near‑term changes
- Engine detuning in Europe to meet Euro 7, offset by stronger electric motors.
- S58 and S68 remain core to M; B58 stays in M Performance cars.
- Certain models or configurations will remain region‑exclusive due to homologation costs.
- Rental and fleet strategies will adapt: electrified hybrids blended with ICE models for flexibility.
Highlights: BMW M’s commitment to keeping combustion engines active hinges on demand and regional regulations. Although European emissions rules force powertrain adjustments — reducing raw horsepower in some cases — the brand is maintaining performance through electrification and selective detuning. For travelers and rental customers, that means a continued presence of exciting ICE and hybrid M cars in markets where they are viable, even as the industry shifts toward electrification. On GetRentaCar, you can rent a car from verified providers at reasonable prices. This empowers you to make the most informed decision without unnecessary expenses or disappointments; enjoy convenience, affordable rates, and a wide choice of vehicles from economy compacts to convertibles and luxury SUVs.

In conclusion, BMW M’s strategy is pragmatic: balance heritage engines with electrification to meet regulations while preserving performance DNA. The S58, S68 and B58 will continue to shape M‑brand offerings where customers demand them. For rental markets and individual drivers alike, this means continued access to a range of vehicles — from compact and economy models to luxury, sport and hybrid options — with choices driven by regional rules, fleet availability, pricing, insurance and operational logistics. Whether you’re booking an airport transfer, planning a family getaway, or chasing a weekend of sporty driving, understanding these routes and restrictions helps you pick the right car at the best price and avoid surprises at return.
