Metallica embarked on the European leg of their M72 World Tour in Munich, Germany, featuring a lineup of alternative fuel-powered vehicles. The tour buses, maintained by Shell, were fueled by a mix of hydrogen, biofuels, LNG, and renewable diesel for the 2-month, 7,200-mile journey across nine countries. The fleet included Iveco's special-edition natural gas and renewable diesel trucks, as well as the company's hydrogen fuel-cell trucks powered by Hyundai's HTWO systems. Shell's renewable fuels played a key role in sustaining the diverse fleet. The tour highlighted the challenges of infrastructure gaps for EVs and hydrogen trucks, limiting their use to promotional events due to range limitations. Despite these challenges, the collaboration between Iveco and Metallica showcased the progress in using alternative fuels in heavy-duty transport, emphasizing the importance of continued innovation. The partnership between Iveco and Metallica aims to promote environmental sustainability and social responsibility, with plans to release a limited edition of heavy-duty trucks inspired by the band. The tour's impact extends beyond music, shedding light on the carbon footprint of the metal genre and the industry's efforts to decarbonize through alternative fuels and innovative solutions.
