The concluding day of 2026 F1 Pre-Season Testing at the Bahrain International Circuit saw Charles Leclerc set the overall fastest lap of the entire six-day programme. The Ferrari driver delivered a time of 1:31.992s on the C4 compound Pirelli tyres during the final hour of running, improving by eight-tenths of a second on the previous benchmark established by Kimi Antonelli. This performance placed him ahead of Lando Norris in the McLaren, who recorded a 1:32.871s on the C3 tyre. Max Verstappen and George Russell followed, with times of 1:33.109s and 1:33.197s, respectively, both also set on the C3 compound. Notably, none surpassed Leclerc's own leading time on that particular compound, a 1:32.655s. Pierre Gasly rounded out the top times, utilising the softest C5 tyres to post a 1:33.421s.

The C5 compound saw limited use on the final day, employed only by Alpine and Williams for short-run simulations. Aston Martin, despite having the tyre available, opted not to run it and instead completed just six laps on C3s before their session was curtailed. In contrast, teams focused on different aspects of performance. Gabriel Bortoleto and Arvin Lindblad set the pace on the harder C1 and C2 compounds, respectively. The day was also notable for the absence of several drivers, including Fernando Alonso, Lewis Hamilton and Alex Albon, who did not participate in any track action.

Beyond outright speed, teams dedicated significant effort to long-distance evaluation. Gabriel Bortoleto completed 25 laps on the C2 compound for Audi, while Esteban Ocon undertook 24 laps on C1s for Haas. Ocon was also the sole driver to run intermediate tyres, completing four laps to assess front wing behaviour. Over the entire six-day test, a total of 41,366 kilometres were covered across all 11 teams, a distance exceeding the Earth's circumference. The C3 compound proved the most popular, accounting for 61 percent of all laps. In total, 591 sets of slick tyres were utilised throughout the pre-season, with 326 of those deployed in the final three days alone.

Mario Isola, Pirelli’s Motorsport Director, said, “The radical changes introduced to the cars have inevitably shifted the teams’ focus towards power units and aerodynamics rather than tyres over the last few days. The final stages of testing are usually dedicated to optimising the car-tyre package, but it is clear some teams haven’t reached that point yet. Generally speaking, track feedback has been consistent with our simulation expectations. Drivers were able to gain confidence with the entire Pirelli range through both performance trials and long runs, even using the C4 and C5 compounds which aren’t particularly suited to a circuit like Sakhir.

“Mechanical resistance appeared strong across all options, with no signs of graining or blistering. Degradation levels are almost certainly higher now than what we expect for the Bahrain race, when temperatures will be lower and cars more developed. A central theme this season will certainly be balancing temperatures between the axles, especially ahead of the first race in Melbourne. The lower loads of a street circuit might require more intensive tyre preparation or differentiated tyre blanket temperatures, particularly in qualifying. In any case, it will be interesting to discover in Australia how much teams have been ‘sandbagging’ their engine power to avoid showing their hand. We only have to wait a couple of weeks to see the true pecking order.”

The Alliance for the Future of Tyres (AZuR) has released a revised Green Paper examining tyre circularity across Europe. This document explores the benefits of extending tyre life through retreading, repair and reprofiling, alongside mechanical and chemical recycling. It illustrates how circular economy principles can advance climate goals, preserve resources and strengthen industrial competitiveness.

The paper presents targeted appeals to political leaders, stressing the urgency of adapting legal structures to unlock current potential. It echoes the European Court of Auditors regarding robust recycling markets, which depend on consistent enforcement and dependable funding. Christina Guth, coordinator of the AZuR network, frames the tyre circular economy as a demonstration of sustainable practice, where environmental protection and economic activity reinforce one another.

The paper acknowledges the Clean Industrial Deal as constructive, yet argues circularity must occupy a more central position. Products must be conceived from the beginning with reuse and recycling in mind if materials are to remain in circulation. This gains urgency as the mobility sector expands, bringing increased tyre waste. A functioning circular system for tyres presents an avenue for reconciling ecological pressures with economic development.

The initiative coordinated by AZuR unites more than 80 organisations spanning industry, small business and research. In Germany, over half of the more than half a million tonnes of annual tyre waste is cycled back into use, with collected materials evaluated by certified operators.

Despite existing capabilities, the paper asserts political engagement remains insufficient. It enumerates requests for governing bodies, including support for repair enterprises, binding sustainability benchmarks and inclusion of retreaded options in public procurement. Another element involves cultivating a European market for premium recycled substances.

The paper also advocates for clear regulations regarding novel recycling methods and for recycled content to be granted equivalent status to virgin materials. Such measures are presented as essential for protecting investment in sustainable innovation.

Broader European trends indicate circular systems are increasingly viewed as integral to a resilient industrial approach. Advanced recovery infrastructure aids climate objectives and underpins material security. The European Court of Auditors has called for reinforced policy conditions that enable recycling economies to thrive, highlighting consistent rule application and stable financing for recovered materials.

Hankook Tire, the official tyre supplier to the FIA World Rally Championship (WRC), concluded its participation in the 2026 Safari Rally Kenya, which took place in Naivasha, Kenya, with the event wrapping up on 15 March 2026. The challenging terrain of the Kenyan savanna provided a rigorous test for Hankook’s specialised equipment. Throughout the rally, the company provided its Dynapro R213 tyre, engineered specifically for severe off-road conditions. This extreme all-terrain tyre was available in Hard and Soft compounds and featured a robust casing structure alongside an optimised tread design. These characteristics ensured reliable grip and accurate steering response despite the demands of high-speed rallying.

A key development was the introduction of an upgraded soft gravel tyre at this event. It delivered superior traction on wet and slippery sections while retaining its structural integrity amidst the unpredictable conditions. The rally unfolded across the rugged landscapes of Naivasha and the Great Rift Valley, where competitors faced sharp rocks, deep sand and treacherous fesh-fesh dust. Fluctuating weather further compounded the difficulty, making consistent tyre performance critical for drivers to reach the finish line. Ultimately, Toyota Gazoo Racing's Takamoto Katsuta emerged victorious after four gruelling days, reinforcing the event's reputation as one of the season's most demanding.

Looking ahead, the championship moves to Europe for its fourth round, the WRC Croatia Rally 2026, scheduled from 9 to 12 April 2026 along the Adriatic coast. Returning to the WRC calendar after being part of the European Championship in 2025, the rally has generated significant interest with its redesigned route that navigates both coastal and mountainous terrain. For this event, Hankook will supply its Ventus Z215 and Z210 tyres, high-performance tarmac compounds designed to meet the rigorous demands of the course. These tyres have previously proven their effectiveness in similar environments, such as during the 2025 Rally Islas Canarias, where coastal and mountainous stages demanded exceptional vehicle control and tyre resilience.

Since taking over as the exclusive tyre supplier for all WRC classes in 2025, Hankook has leveraged data from its involvement in over 70 global motorsport championships. The company applies these race-proven insights to advance its ultra-high-performance tyre technology, continually reinforcing its leadership in the field.

Yokohama Rubber has announced that it will supply ADVAN racing tyres for a newly developed BMW M Motorsport entry set to compete in this year’s Nürburgring 24-Hour Race and the Nürburgring Langstrecken-Serie (NLS). As an official partner of BMW M Motorsport, the company is supporting the BMW M3 Touring 24H, a vehicle designed specifically for the Nürburgring circuit and built with fans in mind.

This special model shares its technical foundation with the BMW M4 GT3 EVO but is constructed using the body shell of the BMW M3 Touring. It measures 200 millimetres longer and stands 32 millimetres taller than its GT3 counterpart, including the rear wing. Despite these dimensional differences, the mechanical specifications of both vehicles remain identical. The car will compete in the SPX class, a category dedicated to high-performance experimental vehicles and concept cars with unique modifications that do not conform to other classifications. This class plays a key role in testing and refining new automotive technologies.

Yokohama’s renewed involvement with BMW M Motorsport at the Nürburgring marks a significant return, as the two last collaborated at this event between 1980 and 1990, a period during which they secured two overall victories. This season represents their first partnership at the track in nearly four decades. In addition to supplying tyres for the BMW M3 Touring 24H, Yokohama will also equip the BMW M4 GT3 EVO, which is entered in the SP9 class for GT3-spec production vehicles.

Beyond its work with BMW, Yokohama Rubber will provide tyres to several leading teams participating in both the Nürburgring endurance series and the iconic 24-hour race, further extending its presence in one of the world’s most demanding motorsport events.
