Lawson reveals 'biggest challenge' of Red Bull switch

When Liam Lawson received the call from Red Bull on Wednesday ahead of the Dutch Grand Prix at Zandvoort, he knew he would face one of the most difficult tasks of his career: switching from the familiar Racing Bulls car to the RB21 – a completely different machine. But what worried the New Zealander was not just the pressure of racing for the top team, but the profound difference in how the two cars operate – a challenge he calls the 'biggest' in this transition. The context of this upheaval stems from Isack Hadjar's wrist injury, which prevented him from racing at Zandvoort and Monza. Red Bull quickly moved Lawson – who was demoted to Racing Bulls after the Japanese Grand Prix – back to the main team to replace him. Meanwhile, Yuki Tsunoda, who had been promoted to Red Bull after the Japanese race, was moved down to Racing Bulls to fill the vacancy. This rotation not only created a rare natural experiment in F1 – where the same driver drives two different cars in the same season – but also revealed fundamental differences in design philosophy between the two teams within the Red Bull group. The key point Lawson emphasized is the difference 'everywhere, other than the power unit' between the Red Bull RB21 and Racing Bulls. He described Red Bull's high-speed grip as 'the most impressive', while the car's balance is 'very different', including the feedback through the steering and the way it moves around. Notably, Lawson said that even in the simulator, the two cars feel completely different. This confirms that, in the ground-effect era of 2026-2026, the chassis – not the engine – is the primary differentiator in performance. The fact that two cars sharing the group's technical resources are 'different everywhere' highlights the limits of internal technology transfer, partly due to the cost cap regulations restricting IP sharing between the two teams. From a tactical perspective, Lawson's confirmation on Wednesday – rather than at the last minute – gave him enough time for a simulator session and normal preparation. However, Zandvoort was a Sprint weekend, with only one practice session, making adaptation to the RB21 more stressful. Lawson admitted it was 'stressful but overall a good weekend' as he finished P7 and scored points. In contrast, Monza will be a normal weekend with three practice sessions, which Lawson believes 'should be easier to adjust' and represents 'another good opportunity'. This difference in weekend format is a significant tactical advantage, giving him roughly two extra hours of track time to familiarize himself with Red Bull's different balance and steering feedback. A critical blind spot many might overlook is Lawson's dual-preparation strategy. He 'talked to both teams' engineers to stay ready for both', a professional approach but costly in time and energy. This not only reflects the uncertainty of his position – as he did not know which car he would drive until Wednesday – but also shows the cognitive burden a driver must bear when maintaining readiness for two completely different machines. Lawson's honesty about this difficulty is a positive signal, showing he is not overconfident but understands the real technical challenges. Looking further, this rotation is not just a temporary upheaval due to injury. It is becoming an extended evaluation for Red Bull's second driver position in the 2026 season – when new engine and chassis regulations take effect. Lawson, with his P7 performance at Zandvoort, is proving he deserves a long-term opportunity. Meanwhile, Tsunoda, with his second demotion in a season, faces an uncertain future in the Red Bull program and may have to explore external options. The competition between these two drivers at Monza – one at Red Bull, one at Racing Bulls – will be a direct test of ability, and the outcome could shape the 2026 driver market. The difference between the two cars also raises a deeper strategic question: is Red Bull sacrificing team stability to pursue maximum performance? The RB21, with its superior high-speed grip, may be a faster machine, but it demands precise driving style and a narrower operating window. Conversely, Racing Bulls may be easier to drive but has a lower performance ceiling. Lawson's constant adaptation to two different balance philosophies not only affects his results but also reflects a larger reality: in modern F1, a driver's flexibility in adapting to different car characteristics is an invaluable asset, but also a challenge not everyone can overcome. As Monza approaches, Lawson will have the opportunity to use three practice sessions to fine-tune his feel for the RB21. But the bigger question remains: is the technical difference between the two cars the biggest barrier he must overcome, or is it just part of a larger puzzle about Red Bull's stability and long-term strategy? The answer may be revealed not only through the result at Monza, but also through how Red Bull shapes its lineup for the future.
