McLaren completed private testing in Barcelona between 26 and 30 January 2026. The team resolved initial concerns over the reliability of the new car for the season that introduces new technical regulations.
Andrea Stella, team leader, highlighted that the problems encountered were quickly overcome. Engineers worked intensively to make up for lost time and validate the functioning of the MCL40.
The sessions involved nine of the ten teams from Fórmula 1. Apenas to Williams did not participate in the shakedown held at Circuito of
Private tests on the Catalan circuit
The tests took place over five days on the Spanish route. The teams have accumulated important mileage with the cars designed under the new 2026 rules.
McLaren faced initial setbacks related to the complexity of the integrated systems. Essas issues were resolved with adjustments made during the night work sessions.
Other teams also reported similar problems in the first few laps. Most were able to complete extensive assessment programs in the following days.
The shakedown served as the first opportunity to validate components on a real track. The information collected will be essential for adjustments before official pre-season testing.
Andrea Stella’s statements
Andrea Stella emphasized the high level of preparation shown by the teams. Fears of a repeat of the reliability problems seen in 2014 quickly disappeared during the sessions.
The Italian driver explained that the greatest complexity lies in the car’s general system. The hybrid power units showed stable performance from the first laps.
McLaren lost some of its planned mileage at the start of testing. The recovery took place thanks to the joint effort of mechanics and engineers who worked without interruption.
New technical regulations from 2026
The 2026 season introduces significant changes to the power units. The electrical power increases substantially in relation to the thermal component.
The cars feature active aerodynamic systems to improve energy efficiency. Essas solutions require precise integration between chassis and power unit.
The teams developed completely new designs to meet the requirements. McLaren opted for its own concept on the sides of the car.
Weight distribution has been changed to accommodate larger batteries. The minimum weight of cars has been reduced compared to previous generations.
Performance observed in Barcelona
McLaren completed hundreds of kilometers during the five days of activity. The program included verification of hybrid systems and evaluation of mechanical components.
Oscar Piastri participated in sessions behind the wheel of the camouflaged MCL40. The Australian pilot focused his efforts on collecting data for correlations with the simulator.
Lando Norris also ran on the Catalan circuit. The two incumbents shared setup validation tasks and starting procedures.
Mild January temperatures facilitated extended testing. The track offered representative conditions for initial tire wear assessment.
Preparation of competing teams
Nine teams were present at the Spanish shakedown. Ferrari, Mercedes and Red Bull have also accumulated significant mileage.
Mercedes has supplied power units to McLaren and customer teams. The engines showed stable operation under different conditions of use.
Red Bull worked with its new power unit developed in-house. Tests indicated progress in integration with the chassis.
Ferrari focused efforts on validating electronic systems. The Italian team completed an extensive program without serious interruptions.
Positive aspects highlighted
- Quick resolution of initial reliability issues
- Accumulation of valuable data for development
- Validation of new aerodynamic concepts
- Stable integration between power unit and chassis
- High preparation of all participating teams
Next steps for mclaren
The Woking team will direct efforts towards detailed analysis of the data collected. The information will guide updates before official pre-season testing.
The calendar foresees collective sessions in February. The traditional location of Bahrain should receive teams for three intensive days.
McLaren remains focused on the continued development of the MCL40. The objective focuses on maximizing the package’s potential within the new technical rules.
The experience accumulated in Barcelona reinforces internal confidence. The team believes it is well positioned to start the season at Bahrein.
Fórmula 1 enters a new era with regulations that prioritize sustainability. The changes aim to attract new manufacturers and reduce emissions.
The cars of 2026 use 100% sustainable fuel. Total power remains close to current levels despite the different split between components.
Active aerodynamics allows wing adjustment in specific sections. The system aims to reduce drag on straights and increase downforce in curves.
Safety remains top priority in the new rules. Estruturas of protection received additional reinforcements for side impacts.
