- More than 130,000 tyres already tested
- Continental’s tyre braking test facility is one of the most modern facilities in the world
- “We can achieve a particularly high level of comparability of the test results in a fully air-conditioned, weather-independent and fully automated environment,” says Meletis Xigakis, Head of Global Tire Testing at Continental
HANOVER, Germany – Continental has carried out more than a million trips on its fully automated tyre braking test facility known as the AIBA (Automated Indoor Braking Analyzer) since 2012. The facility, which is unique worldwide, enables precisely reproducible test processes to check the performance of new car and van tyres on different road surfaces – dry and wet – under laboratory conditions.
Its advantages lie not only in the special test environment. In the facility, unmanned, rail-guided vehicles are automatically accelerated to speeds of up to 120 km/h along a track almost 100 metres long. They are then braked autonomously on a 75-metre long braking track. No fuel is required for this process. This is because the acceleration takes place with the help of an electromagnetic linear drive borrowed from modern roller-coaster technology.
The AIBA facility also eliminates the need for the many kilometres of driving that are required on normal test tracks for starting off and pulling away. The test facility is thus an example of Continental’s strong commitment to maximum driving safety in traffic. It also reflects the company’s comprehensive efforts to develop and produce increasingly environmentally friendly tyres.
“The AIBA facility is one of the most modern braking test facilities for tyres in the world. Even after being in use for more than 10 years. We can achieve a particularly high level of comparability of the test results in a fully air-conditioned, weather-independent, and fully automated environment,” explained Meletis Xigakis, Head of Global Tire Testing at Continental. “Braking is essential for road safety. That’s why we put a lot of effort into being able to analyze the performance of our tyres as precisely as possible.”
More than one million test drives for maximum safety on the road
Around two-thirds of all tyre braking tests at Continental take place in the AIBA facility. The focus here is on prototypes of new tyres, for which the interaction of new or modified rubber compounds and tread designs is validated and further optimized. It is also used to verify the performance of a new serial tyre. Since commissioning, developers have tested more than 130,000 tyres. In almost 12 years, more than a million test drives have been completed.
In contrast to virtual simulations, the fully automated tyre braking test facility uses real vehicles on real road surfaces. This enables efficient, precise, and comparable tyre tests – regardless of changing external influences such as temperature, wind, and sunlight. The braking tests can even be carried out independently of vehicle-specific properties. Continental has also been testing tyres since 2022 with the help of the Analytical Vehicle AIBA (AVA). This is a fully electric, driverless test vehicle developed in-house that can be used instead of a serial car or van.
High tyre quality thanks to extensive testing
The physical tests in the AIBA facility are an integral part of extensive testing procedures that Continental uses to ensure that its tyres offer optimum performance on dry, wet, snowy, and icy roads. Before the actual start of production, new tyre models cover around 25 million kilometres a year on roller drum test rigs and test tracks. This corresponds to around 625 orbits around the earth. This also includes test drives to determine the subjective road performance of tyres with professional test drivers, which are carried out on Continental’s worldwide test tracks.
The huge effort that Continental puts into its tyre tests pays off. One example of this is the WinterContact TS 870, which received “top marks on wintry and wet roads” in the ADAC’s 2023 winter tyre test and thus took first place. The ADAC, Europe’s largest automobile association, praises the precise and reliable braking performance on dry roads, the uncompromising braking performance on wet and wintry roads, and the high predicted mileage of this tyre. Continental’s extensive testing procedures made the tyre’s performance possible in the first place.
Sustainability and efficiency through AIBA
The innovative tyre braking test facility also supports Continental’s sustainability strategy. Over the past 12 years, valuable resources have been saved thanks to the AIBA facility and the electromagnetic linear drive. Around 166,000 kilometres needed on normal test tracks for starting off and pulling away have been avoided. This has saved 16,600 liters of fuel and almost 40 tons of CO2.
The electricity for the AIBA braking test facility has been generated entirely from renewable energy sources since the end of 2020. Since then, Continental has been using it at all its production and test locations. To this end, the company obtains guarantees of origin following the criteria of the global RE100 initiative.
Continental is committed to making tyres even more energy efficient and environmentally friendly in terms of production, use, and recyclability. To this end, the premium tyre manufacturer consistently invests in the research and development of new technologies, alternative materials, and environmentally friendly production processes. Continental aims to achieve 100 percent carbon neutrality along its entire value chain by 2050 at the latest.
