Ferrari’s victory at Silverstone has reignited a debate that has surrounded the Scuderia since the beginning of the season: is the Power Unit really the weakest point of the SF-26?
For months, many observers blamed Ferrari’s engine for the performance gap to its rivals. However, the data gathered over the past few Grands Prix tells a different story. The performances seen in Barcelona, and especially at Silverstone, suggest that the real limitation of the SF-26 lies not in the internal combustion engine itself, but in the overall utilization of the entire Power Unit.
Ferrari’s engine and the Power Unit are not the same thing
One of the most common misconceptions is treating the terms Ferrari engine and Ferrari Power Unit as if they were interchangeable.
In Formula 1, they are not.
The Internal Combustion Engine (ICE) is only one component of the complete Power Unit.
The full hybrid system also includes:
- the internal combustion engine (ICE);
- the turbocharger;
- the MGU-H;
- the MGU-K;
- the Energy Store (battery);
- the electronic control unit;
- the energy recovery and deployment systems.
Assessing the performance of a Formula 1 Power Unit therefore means evaluating the entire hybrid package, not simply the horsepower produced by the combustion engine.
Is Ferrari really behind in engine performance?
The evidence collected during the Silverstone weekend appears to provide a fairly clear answer.
Along the fastest sections of the British circuit, the SF-26 recorded highly competitive top speeds and was frequently among the quickest cars on the straights. If Ferrari’s internal combustion engine were genuinely lacking performance, those figures would be difficult to explain.
This leads to an important conclusion: the Ferrari ICE does not appear to be the car’s primary limitation.
The real challenge is Power Unit management
The area where Ferrari still has room for improvement is how the Power Unit is managed throughout an entire lap. In modern Formula 1, success depends not only on how much power is available, but also on when and how that power is delivered.
Energy management has become one of the most sophisticated aspects of the sport.
Every lap requires a delicate balance between:
- recovering energy under braking;
- deploying electrical energy efficiently;
- managing battery charge;
- optimizing the use of the MGU-K;
- selecting the ideal deployment strategy for each sector of the circuit.
Even with a highly competitive engine, inefficient energy distribution can significantly compromise overall performance.
Silverstone revealed a different Ferrari
The British Grand Prix highlighted a noticeable change in Ferrari’s performance.
Charles Leclerc maintained remarkably consistent pace throughout his opening stint, showing none of the performance drop-offs normally associated with critical energy deployment zones. This suggests Ferrari has made meaningful progress in managing the Power Unit as a complete system.
Energy deployment strategies are developed alongside both aerodynamic and mechanical setup. A more stable car allows engineers to maximize energy recovery under braking, while improved aerodynamic balance helps optimize traction on corner exit, reducing unnecessary energy losses.
For that reason, Ferrari’s improvement at Silverstone is likely the result of several factors working together rather than simply introducing a more powerful engine.
Why the simulator got it wrong
Before the British Grand Prix, Ferrari admitted that its simulator had predicted a very difficult weekend. What happened on track turned out to be the exact opposite. This strengthens the theory that the SF-26’s performance potential had always existed, but the team had not yet found the ideal setup to unlock it.
Once Ferrari discovered the right compromise between aerodynamic balance, mechanical setup and Power Unit management, the behaviour of the car changed dramatically.
Spa will provide the ultimate test
Spa-Francorchamps remains one of the toughest tests for any Formula 1 Power Unit. Its long straights place maximum emphasis on engine performance, while the repeated acceleration zones demand exceptionally efficient electrical energy management.
If Ferrari can reproduce its Silverstone performance at the Belgian circuit, it will provide even stronger evidence that the team’s biggest weakness was never the engine itself, but rather the way the complete Power Unit was being utilized.
Ferrari can be increasingly optimistic
The signs gathered over the past few weeks are certainly encouraging.
The SF-26 appears to have found a much more effective operating window, allowing Ferrari to extract significantly more performance from a Power Unit that may have been judged too harshly earlier in the season. Rather than suffering from a shortage of horsepower, Ferrari seems to have addressed one of modern Formula 1’s most complex engineering challenges: transforming the full potential of its hybrid Power Unit into consistent performance throughout an entire lap.
If Spa confirms the progress seen at Silverstone, Ferrari could head into the second half of the season with ambitions far greater than anyone would have imagined only a few weeks ago.
