Carlos Sainz questions F1 rulebook after software glitch in Malaysia
Formula 1 faced severe criticism from drivers and team principals following a software glitch that delayed the Bahrain Grand Prix in Malaysia by an hour and a half, prompting calls for a comprehensive review of the sport’s complex regulations.
Software Glitch Derails the Malaysian Grid
The disruption occurred before the race started when a software bug in the wet-weather engine map prevented multiple cars from moving on formation laps. The start was abandoned while engineers issued a new software code. Governing body the FIA launched a full review into the incident. The problem surfaced because wet-weather running has been sparse this year, leaving the specific triggering conditions untested prior to the event.
Carlos Sainz, serving as a director of the Grand Prix Drivers’ Association, questioned the long-term trajectory of the rulebook. Who decided five years ago that this was the direction to go?
Energy Management and Power Unit Deficits
The operational software failure highlighted broader discontent regarding the current engine regulations, which enforce a near 50-50 power split between internal combustion and electrical systems. The power units suffer from energy starvation, forcing cars to behave in counter-intuitive ways and diminishing the influence of driver skill. While the engines produce roughly 1,000 brake horsepower at full output, that figure drops to 540 brake horsepower once the batteries deplete.
Complex deployment and recharging cycles occur multiple times per lap under current rules. To manage these constraints, strict operational limitations were introduced, including a reduction of total electrical power from 350kW (470bhp) to 250kW (335bhp) in wet conditions, which directly triggered the software fault in Malaysia. Rule idiosyncrasies force cars to decelerate at the end of straights to recover energy. Two-time champion Fernando Alonso described challenging fast corners as functioning as charging stations for the car.
FIA Shifts Energy Distribution Toward Internal Combustion
Teams warned the FIA about impending energy management challenges as early as 2023, though the 50-50 split remained unquestioned until shortly before the current season began. Red Bull team principal Laurent Mekies noted that the incident shows the need to keep system complexity under control and prevent issues from multiplying. Adjustments have gradually been implemented, including variable energy recovery limits based on circuit characteristics. The energy split is scheduled to shift to a 60-40 distribution favoring internal combustion across two steps by 2028.
Teams and F1 bosses are actively developing a subsequent engine formula designed to eliminate energy starvation entirely. Although FIA president Mohammed Ben Sulayem initially advocated for naturally aspirated V8 engines devoid of hybrid systems, the leading alternative is a V8 turbo utilizing 15 to 25 percent electrical power primarily configured as a push-to-pass mechanism.
