Conti Urban HA 5 NXT Wins the “2026 International busplaner Sustainability Award”

Up to 60 percent* of the materials used in the Conti Urban HA 5 NXT are renewable, recycled, and ISCC mass balance certified. ISCC (International Sustainability and Carbon Certification) enables the traceability of renewable and recycled raw materials throughout the supply chain. An externally certified life cycle assessment shows an 11 percent reduction in greenhouse gas emissions compared to the predecessor model, the Conti Urban HA 3**. The materials used include natural rubber, renewable fillers, recycled synthetic rubber, and rubber from mechanically processed end-of-life tires.

Tire development aligned with Urban Mobility Trends  

The Conti Urban HA 5 NXT was developed to meet the demands of the key megatrends shaping urban public transport: urbanization, electrification, and digitalized fleet management. According to data from the European Automobile Manufacturers’ Association (ACEA), new bus registrations in the EU continued to grow in 2025, with particularly strong momentum in major markets such as Germany and Poland. 

At the same time, the share of electric bus registrations increased significantly, while the importance of conventional technologies declined further. Several European markets such as Germany, Sweden and Belgium recorded strong growth rates in electric bus registrations, underlining the accelerating transition. 

Efficient Performance in Urban Traffic

A 25 percent reduction in rolling resistance compared to the previous generation supports energy-efficient electric bus operation and can enable range gains of up to 15 percent*. In addition, a newly developed tread compound delivers up to 15 percent higher mileage compared to the Conti Urban HA 3***. The tire maintains an EU wet-grip label rating of B. A reinforced sidewall design improves resistance to curb and impact damage in city traffic, while the optimized tread pattern contributes to secure traction and reduced noise levels, enhancing passenger comfort. 

Ready for Digital Tire Management

The Conti Urban HA 5 NXT is fully compatible with Continental’s digital tire management system ContiConnect. Using sensor technology, fleet operators can monitor tire pressure, temperature, and wear in real time, enabling proactive maintenance planning. This digital integration helps increase operational safety, reduce unplanned downtime, and supports cost-effective fleet management for urban bus operators.

A Relevant Award for the Bus Industry

The “International busplaner Sustainability Award”, first presented in 2013, is regarded as one of the most established sustainability awards in the European bus and transport sector. It honors companies that successfully combine economic performance with environmental stewardship and social responsibility, contributing to the sustainable development of public transport.
