Ferrari’s Baku deficit explained: engine costs 0.3s, but SF-26 loses another half-second

Charles Leclerc fought his way onto the front row for Ferrari in Baku, but the excellent starting position cannot disguise the scale of the deficit. The Monegasque finished more than eight tenths behind Mercedes, raising a bigger technical question for the SF-26: if around three tenths can be attributed to Ferrari’s 20-22 hp power-unit shortfall on the main straight, where is the other half-second being lost?

The answer matters because George Russell’s dominant Azerbaijan Grand Prix pole was not secured by a marginal advantage. George Russell claimed the 12th pole position of his Formula 1 career and his fifth of the season with a margin rarely seen in a championship increasingly decided by thousandths of a second.

Charles Leclerc’s Baku P2 cannot hide Ferrari’s gap to Mercedes

Toto Wolff was in Viterbo following his son Jack’s karting activities when George Russell produced his outstanding qualifying performance. George Russell, eager to rebuild a reputation that has taken a significant hit from Kimi Antonelli’s performances this season, went searching for the perfect lap and succeeded in putting a substantial distance between himself and the rest of the field.

Charles Leclerc appeared satisfied with the lap he had produced at the end of Q3, but the scale of the gap to the Mercedes W17 changed the picture. Ferrari may have secured a valuable front-row position, yet unless something removes both Mercedes cars from contention – with Kimi Antonelli’s recovery through the field also worth watching – the Scuderia appears to have limited prospects of securing its first victory in Baku.

Even defending second place could prove difficult, with McLaren and Red Bull capable of mounting a challenge. Ferrari’s difficulties cannot be explained purely by the 067/6 power unit either. The extremely long Baku acceleration zone, stretching for more than two kilometres, exposes the estimated 20-22 hp deficit to the Mercedes six-cylinder engine particularly clearly.

Ferrari engine deficit costs three tenths – but another half-second remains

In lap-time terms, Ferrari’s engine deficit has been measured at approximately three tenths of a second along the long run towards the finish line. The recorded speeds and straight-line differences can also be explored through the F1 Top Speed Comparison.

That still leaves roughly another half-second to explain. It is therefore difficult simply to argue that the SF-26 possesses the best chassis and the most aggressive aerodynamic concept when Mercedes, which has not received a major update package since the Canadian Grand Prix, can exploit its power unit while also demonstrating what appears to be the most efficient overall car on the grid.

For Mercedes technical director James Allison, the results provide strong evidence that the W17’s advantage is not confined to the engine. The package is proving highly competitive across power unit, chassis and aerodynamics, with the occasional reliability concern around the engine remaining its most obvious weakness. The wider scale of Mercedes W17’s 2026 performance advantage has already become one of the defining technical themes of the season.

Ferrari, by comparison, has not progressed as much as expected in its attempt to close the gap during the second half of the championship. The team has now gone four consecutive races without a podium, making a return to the top three particularly important for restoring momentum inside an environment that has gradually lost some of its early-season optimism.

SF-26 stiffness and drag add to Ferrari’s Baku problem

Those familiar with the SF-26’s behaviour believe the car is running too stiff. Television footage regularly shows Charles Leclerc bouncing more than would be desirable, although minimum ride height may only be part of the explanation rather than the underlying problem.

The deeper concern is aerodynamic drag. Ferrari appears to generate too much resistance, and in order to obtain the traction grip it needs – an area in which Mercedes excels – the team is forced towards a higher-downforce configuration than would otherwise be desirable. That makes it more difficult to offset even part of the Ferrari power-unit deficit on the straights.

The issue fits with the wider pattern highlighted by Ferrari’s Baku telemetry and cornering analysis: the SF-26 can no longer rely on its performance through the corners to compensate fully for what it gives away elsewhere on the lap.

There is therefore a growing suspicion that Ferrari is approaching the limit of what the current SF-26 concept can deliver. The latest Baku FP3 technical analysis had already shown some progress in deployment and setup, but the underlying limitations remained visible.

Ferrari waits for Austin as Mercedes prepares another step

Ferrari is waiting for its final upgrade package, scheduled to arrive in Austin. Mercedes, however, is expected to introduce its own update in Malaysia for the Bahrain Grand Prix and debut the ADUO1 engine specification. Against that background, it is difficult to imagine Ferrari suddenly being able to challenge Mercedes consistently, even at Singapore, a circuit whose characteristics appear particularly well suited to the SF-26.

The immediate objective for Ferrari therefore remains clear: defend second place in the Constructors’ Championship from McLaren and return to the podium. In the current circumstances, bringing the SF-26 home behind the Mercedes W17 in Azerbaijan would almost feel like a victory.
