The opening two rounds of the Formula 1 season have revealed a subtle but significant trend — one that was already hinted at during pre-season testing in Bahrain and now appears firmly established.
Through races in Melbourne and Shanghai, the Racing Bulls VCARB 03 has emerged as one of the most difficult cars to overtake on the grid. What initially looked circumstantial is now pointing toward a defining characteristic of the Red Bull-Ford power unit.
In Australia, Oliver Bearman experienced the VCARB 03’s defensive strength first-hand, spending lap after lap trapped behind Arvid Lindblad without finding a way through. The same pattern repeated in China, where Racing Bulls consistently managed to keep rivals at bay.
At the core of this resilience lies a distinctive quality of the Red Bull power unit: its ability to maintain strong top speeds, particularly in the final phase of straights where others begin to suffer more pronounced derating. Even during the early Bahrain test days, unusually high terminal speeds hinted at a different hybrid deployment philosophy compared to competitors.
The Red Bull powertrain appears to favour sustaining speed at the end of long straights, transforming top-end performance into a powerful asset in both qualifying and wheel-to-wheel combat.
Melbourne provided the clearest example. Its multiple straights and limited energy recovery opportunities forced pursuing drivers to expend significant battery energy in overtaking attempts. That created a strategic dilemma: attack aggressively and risk vulnerability in the next sector.
In precisely this scenario, the Racing Bulls’ superior top speed became decisive. Overtaking required heavy energy deployment, but the VCARB 03’s straight-line strength made it exceptionally difficult to complete the move cleanly.
Shanghai told a slightly different story. The long back straight and greater energy storage opportunities reduced the relative importance of pure top speed. Yet even there, Racing Bulls proved capable of defending effectively, particularly in qualifying trim on an energy-sensitive layout.
On tracks with long flat-out sections and high energy sensitivity, Racing Bulls has established itself as arguably the strongest of the midfield contenders over a single lap.
Race pace, however, paints a more nuanced picture. Over longer stints, the Faenza-based team appears to suffer slightly more than Haas, whose chassis looks highly competitive despite operational limitations tied to its Ferrari power unit.
A similar pattern can be observed at Red Bull Racing. In Melbourne, Red Bull secured a second-row start ahead of McLaren and Ferrari — although Ferrari’s Q3 deployment issues exaggerated the gap more than performance alone justified.
In China, the situation shifted. Red Bull struggled to emerge from the midfield, partly due to first-lap incidents for both drivers, but also because the car revealed a growing deficit to the leaders. That shortfall was not solely power unit-related; chassis deficiencies also played a role.
Intriguingly, Racing Bulls currently appears to be extracting more from certain characteristics of the power unit than the senior Red Bull squad.
Sources suggest the RB22 carries a weight penalty of approximately 15–20kg, compounding aerodynamic shortcomings. By contrast, the VCARB 03 seems better positioned to capitalise on the powertrain’s strengths.
Despite incidents and close battles compromising its race in China, Racing Bulls still secured an impressive seventh place thanks to Liam Lawson’s drive — notably finishing ahead of Isack Hadjar’s Red Bull. Although Hadjar spun early, a well-timed safety car allowed him to recover strategically.
None of this suggests the VCARB 03 is outright superior to the RB22. Rather, it underlines the effectiveness of the work carried out in Milton Keynes on the power unit side. This is the first engine built fully in-house, supported by high-level technical personnel, and its characteristics are beginning to surface clearly.
For both teams, the current limitation relative to their closest rivals does not appear to stem purely from the power unit.
There remains room for improvement on the engine front, but the bulk of the performance gap seems to lie elsewhere. Especially when measured against Ferrari and Haas, the power unit no longer appears to be the primary differentiator.
What is clear after two races is that top speed has become a defining strategic tool — one that Racing Bulls is currently wielding with notable effectiveness. As the season unfolds, how that advantage translates across varying circuit characteristics will be central to understanding the true competitive order within the midfield and beyond.
