The 2027 BMW M5 is shaping up to be one of the most interesting performance sedans in the market. BMW is keeping the latest M5’s plug-in hybrid setup, but the car is getting important powertrain changes aimed at meeting tougher emissions rules coming into force in Europe from 2027.
Instead of moving away from its V8 engine, BMW is refining the combination of a twin-turbo 4.4-liter V8 and electric drive. The result is still a 727-horsepower performance sedan, but with changes designed to improve efficiency and emissions performance.
The M5 Still Has a V8 at Its Heart
The biggest news is that BMW is not abandoning the V8 for the M5. The updated car continues with a 4.4-liter V8 working together with an electric motor as part of BMW’s M Hybrid system.
For the European-market version, BMW has adjusted the V8’s output from 585 hp to 544 hp. That might sound like a major drop, but the electric drive has been software-optimized, allowing total system output to remain at 727 hp.
This means the headline power figure remains extremely high even though the gasoline engine itself has been retuned.
| 2027 BMW M5 | Key figure |
|---|---|
| Engine | 4.4-liter twin-turbo V8 |
| Hybrid system | Plug-in M Hybrid |
| V8 output | 544 hp in updated EU-spec setup |
| Total system output | 727 hp |
| Body style | Performance sedan |
| Drive system | M xDrive all-wheel drive |
| Electric drive | Software optimized |
Why BMW Changed the Engine
The changes are mainly connected with upcoming Euro 7 emissions requirements. BMW says the updated M5 technology was introduced from March 2026 in preparation for regulations taking effect from 2027.
The V8 receives updated engine control, improved exhaust treatment and a Miller combustion process. In simple terms, BMW is trying to make the gasoline engine use fuel more efficiently while reducing emissions.
The interesting part is that BMW has managed to make these changes without reducing the overall system output of the M5. The electric side of the hybrid system helps keep the total power figure at 727 hp.
727 Horsepower Is Still the Big Story
Even with the revised V8, the M5 remains an extremely powerful sedan. Its combined system output of 535 kW, or 727 hp, puts it firmly in the high-performance category.
The electric motor also changes the way the car delivers power. Electric assistance can provide strong response at low speeds while the V8 takes over as speed builds.
That combination gives the M5 a very different character from an old-school gasoline-only sports sedan. It can be quiet and efficient when driven gently, but it has enormous performance available when the driver wants it.
The Hybrid System Is More Than a Fuel-Saving Tool
BMW’s M Hybrid system is not simply there to reduce fuel consumption. It is a major part of the M5’s performance package.
The electric motor adds instant torque and works with the V8 to deliver the car’s total system output. This allows BMW to combine the response of electric power with the high-speed performance of a twin-turbo V8.
The result is a performance sedan that can behave differently depending on how it is driven. It can cruise quietly using electric power for shorter journeys, then use the full hybrid system when maximum performance is required.
The M5 Still Looks Like a Serious Performance Sedan
The current M5 generation already has a much more aggressive appearance than the standard 5 Series. BMW uses wider bodywork, large air openings, sculpted surfaces and M-specific details to separate the M5 from ordinary versions of the sedan.
The design is not just about making the car look aggressive. The wider stance and performance-focused bodywork are part of the M5’s overall high-performance character.
For the 2027 model, the main story is expected to remain the technology underneath rather than a completely new design. BMW’s current updates are focused heavily on the powertrain and emissions changes.
A Luxury Interior With a Performance Focus
Inside, the M5 continues the basic philosophy of the modern 5 Series. The cabin combines premium materials with a digital dashboard and technology designed for both everyday driving and high-speed performance.
This is important because the M5 is not a stripped-down track car. It is designed to work as a luxury sedan during normal driving and then deliver serious performance when needed.
That combination has always been one of the M5’s strongest points. You can use it for daily driving, long highway trips and business travel while still having a car capable of delivering sports-car-level performance.
Fuel Economy Is Still Important
A 727-horsepower sedan is never going to behave like a small economy car, but the plug-in hybrid system gives the M5 another advantage.
BMW’s latest figures for the updated M5 Sedan show weighted combined fuel consumption of around 5.2 to 4.9 liters per 100 km and electric energy consumption of around 17.7 to 17.3 kWh per 100 km under the applicable WLTP test conditions.
The actual result for an individual driver can be very different because plug-in hybrid fuel economy depends heavily on how often the battery is charged and how much of the journey is completed using electric power.
The M5 Touring Is Still Part of the Family
The M5 story is no longer limited to the sedan. BMW also offers the M5 Touring, giving buyers a high-performance wagon with the same 727-hp hybrid system.
The Touring has slightly different efficiency figures because of its body shape and weight. BMW lists weighted combined fuel consumption of around 5.5 to 5.2 liters per 100 km and electric energy consumption of around 18.1 to 17.7 kWh per 100 km under WLTP conditions.
For buyers who need more cargo space but do not want to give up M5 performance, the Touring makes the lineup much more practical.
What Makes the 2027 M5 Different?
The biggest difference is not a dramatic new body or a completely new engine. It is the way BMW is preparing the existing M5 technology for the next stage of emissions regulations.
The updated system focuses on better engine control, improved exhaust treatment and the Miller combustion process. At the same time, BMW has optimized the electric drive software so that total system output remains unchanged at 727 hp.
That approach shows how BMW is trying to keep the M5’s performance character while adapting it to stricter regulations.

Is the 2027 BMW M5 Still a True M5?
Absolutely. The numbers may change slightly under the hood, but BMW has kept the central idea of the M5 intact.
It still combines a powerful V8, electric assistance, all-wheel drive, luxury and everyday usability. The important difference is that the latest version uses hybrid technology as an active part of the performance package rather than treating electrification as a compromise.
For traditional M5 fans, the continued presence of the V8 will be particularly important. BMW is clearly trying to preserve the character of its flagship performance sedan while making the technology cleaner and more efficient.
Final Verdict
The 2027 BMW M5 is not a completely new M5 generation, but it is an important evolution of the current car. BMW is preparing the high-performance sedan for stricter 2027 emissions rules by updating the V8 and optimizing the hybrid system.
The most impressive part is that the overall system output stays at 727 hp despite the changes to the gasoline engine. The updated M5 therefore keeps its extreme performance while gaining a more efficiency-focused powertrain.
For drivers who want a luxury sedan that can cruise quietly, handle daily life and still deliver huge performance, the M5 remains one of Germany’s most complete performance cars.
The 2027 model shows that BMW is not ready to give up the V8 just yet. Instead, the company is using hybrid technology to keep the M5 powerful, fast and relevant in a rapidly changing automotive world.
