Get ready for a mind-blowing revelation as we dive into the world of F1 telemetry!
The year 2026 has brought a game-changing twist to Formula 1 racing, with drivers now facing a unique challenge: managing their speed through corners to conserve battery power. This season, cars are equipped with an impressive 350kW of electrical energy per lap, a significant jump from the previous year's 120kW. It's a new style of racing where going fast sometimes means going slow.
Data from the Bahrain track reveals how energy strategy is transforming performance. And it's not just about the numbers; it's a story of strategy and skill.
Enter Fernando Alonso, the veteran racer known for his sharp insights. He highlighted a critical issue during the first official test in Bahrain: the intervention of the electrical system in racing. His focus? Turn 12 in Bahrain, where his apex speed dropped a staggering 50 km/h compared to previous years. This is a game-changer, and the graph below proves it.
In this year's lap, Alonso couldn't maintain the same speed through Turn 12's apex as he did last year. It seems the Aston Martin team chose to conserve power in this corner, saving energy for other parts of the circuit. But it's not just Alonso; Charles Leclerc's data shows a similar pattern, with a significant speed difference despite being 'flat out' through Turn 12.
The new F1 2026 technical regulations allow an 8.5MJ 'boost' of electrical energy per lap, usable anywhere. However, the battery's capacity is limited to 4MJ per cycle, meaning it needs to be recharged. This has led teams to experiment with strategies, trying to find the best places and methods to recharge.
One method is 'clipping,' limiting power even when the driver is at full throttle. The regulations permit a negative ERS usage of up to -250kW at full throttle, allowing the car to 'steal' power from the internal combustion engine to charge the battery. This effectively reduces the engine power to 150kW, comparable to a standard road car.
The graph below illustrates this point. Leclerc and Lando Norris, the fastest drivers on the second day of testing, had identical data traces during their flying laps. Despite being at full throttle, their car speed remained constant through a 300-meter section of T12, not exceeding 240 km/h. Their laps were remarkably similar, except for Leclerc's slightly higher speed on the start/finish straight and greater confidence through T6 and T7.
Even four-time champion Max Verstappen has expressed dissatisfaction, stating that while he loves driving 'flat out,' this isn't the right way to race. And it's hard to disagree. While technological advancements have enhanced safety, the general consensus is that the driver's skill should always be the primary focus, not overshadowed by technology.
The new technical regulations sometimes push driver skill into the background, allowing the team's strategy and pre-set systems to take the lead. Turn 12 in Bahrain is a perfect example: three different drivers can go 'flat-out' through the same section, but their speed is ultimately determined by the team's pre-planned program, all for the sake of efficient battery charging.
As we move forward into the 2026 season, we can expect more instances where the 2026 cars are either painfully slow or incredibly fast compared to the 2025 generation. The question remains: will this system deliver better, more engaging racing? Only time will tell.
