Formula One fans are in for a significant change as the Drag Reduction System (DRS) is set to be replaced with Manual Override Mode in the 2026 technical regulations. DRS, which was introduced in 2011 to improve overtaking, has faced criticism for making passing too easy and creating artificial racing. The new regulations aim to increase overtaking while eliminating the flaws associated with DRS.
The introduction of Manual Override Mode will rely on the electric power deployment from the MGU-K, part of the hybrid power unit. The following car will receive an energy boost when trying to overtake a competitor, similar to the conditions required for DRS. However, it is yet to be confirmed whether there will be specific zones like with DRS.
The technical details of Manual Override Mode reveal that the battery energy deployment for the leading car will taper off after reaching 290 kph and hit zero at 355 kph. On the other hand, the following car will benefit from its full power allowance up to 337 kph. This means that the following driver will have access to more electrical energy than their opponent ahead, providing a boost for overtaking.
One advantage of Manual Override Mode is that it adds an element of strategy to the race. Drivers will need to recharge after using the mode, unlike DRS where everyone uses it in the same zones if they are in similar windows. This freedom allows drivers to create alternative strategies, as pointed out by Fernando Alonso.
Comparisons can be drawn with IndyCar’s ‘push-to-pass’ system, which was introduced in 2009. Both systems provide extra power to aid overtaking, but there are notable differences. In IndyCar, drivers can use push-to-pass to defend against attacking drivers, while F1’s Manual Override Mode focuses on using electrical power. Additionally, F1’s upcoming power units will have significantly more battery power and a split between electric power and internal combustion.
The introduction of the battery boost in F1 has sparked debate. Some, like Daniel Ricciardo, believe that the smart minds in the sport will find a way to make it work effectively. Others, like Yuki Tsunoda, feel that removing DRS without a suitable replacement would make overtaking challenging, especially with the current heavy and wide cars.
As F1 continues to evolve and improve the racing experience, the replacement of DRS with Manual Override Mode represents a significant shift in strategy. The aim is to maintain the excitement of overtaking while addressing the criticisms and creating a fairer and more authentic racing environment. Only time will tell if Manual Override Mode lives up to expectations and becomes a valuable tool for drivers in their pursuit of victory.
