GCAPS physical testing expertise has led to research and new modelling methods for improved products delivered to our customers, including global vehicle manufacturers, tyre manufacturers, and championship motorsports teams. These clients have used GCAPS modelling and testing services to elevate their performance in vehicle handling, autonomous vehicle technology, and many other aspects of transportation simulation. The ability to provide these services begins with the LTRe (Figure 1).

The LTRe was purpose-built with motorsports in mind. Infused with highly dynamic positioning rates, a maximum speed range of 320 kph, high force capabilities, and electric drives enabling driving and braking conditions throughout the entire speed range makes the LTRe the most dynamically capable machine globally. High spindle torque capabilities and overall size allow GCAPS to test heavier tyres such as light trucks and some commercial truck/bus tyres.

Until the establishment of GCAPS in 2012, the motorsports industry had been limited to either on-track or low-speed machine tests to quantify tyre response. On-track test methods are adequate for simulation validation but are often not comprehensive enough to measure pure tyre response due to vehicle dynamics interference and inconsistent terrains. Low-speed indoor methods will capture tyre responses, but speed limitations result in data extrapolation in trend analysis and tyre models at higher speed ranges. Increasing speed will affect the growth of the tyre, typically shown in loaded radius measurements, thereby changing the tyre’s contact patch dimensions and directly affecting the tyres force generation. This demonstrates the importance of measuring the tyre’s response throughout the vehicle’s operating domain. A tenth of a second in motorsports can mean finishing multiple positions behind the leader. Capturing accurate data at operating speed allows teams to optimize their performance and improve lap time. The LTRe provides such measurements to reduce speed sensitivity compensations in tyre models and measure the tyre’s response more accurately with a flat contact patch interface.

Another illustration of the LTRe’s dynamic capabilities is completing drive file replays (Figure 2). On-track or simulation data can be used as machine inputs to replicate vehicle manoeuvres. This test method can be used to validate tyre models, inform construction and vehicle setup analysis, or test the tyre’s durability. The LTRe is also instrumented with premium thermal measurement sensors (Figure 3) to capture the tyre’s outer and inner carcass temperatures to monitor the thermal state of the tire, develop thermal models, and improve lap-time predictions in simulation. GCAPS has developed a thermal logic algorithm, using customer-defined locations and temperature setpoints, controlling the tyre’s position in the test sequence until the defined setpoints of the tire are satisfied. This method ensures optimal and consistent temperatures are met before testing continues with the most efficient time, which inevitably reduces thermal variations in tyre response.

Heavy emphasis has been placed on vehicle simulations to improve the performance of handling, ride comfort, and safety. These areas are desired by customers and are required to comply with federal regulations.  GCAPS Simulation group produces commercially available tyre models such MF-Tyre™, MF-Swift™, PAC2002, and FTire™. These models are widely known across the industry and used frequently in vehicle dynamics platforms.  Utilizing their dynamic, thermal, and unique cleat capabilities, GCAPS has internally developed procedure methods aimed at improving the model’s fidelity which have been verified with the tyre model creators. These capabilities ensure and improve the robustness of these tyre models by offering dynamic test data to properly characterize the tyre’s response and match innovative vehicle maneuvers.  GCAPS offers both testing and modeling at the same facility, which will improve modeling results, shorten lead times, and reduce costs.  Additionally, GCAPS simulation team has the experience and industry leading expertise to generate tyre models that improve vehicle simulations and enhance the mobility industry. 

Not all race events have ideal sunny and dry days.  Many series will continue the race as rain occurs.  To gain knowledge of the wet tyre response, GCAPS has developed a water delivery system that can apply a consistent water depth to the tyre for speeds up to 250 kph on its LTRe. Using the water delivery system, GCAPS engineers have developed procedures to not only determine a hydroplaning speed, but also how a tire performs for all conditions a vehicle may encounter on roads or racetracks. Using the LTRe coupled with the water delivery system, changes in tyre force generation are measured at various speeds, loads, cambers, pressures, and even water depth. This information provides insight into the tyre’s force generation differences, which can loop back into the stability and safety assessments in wet conditions of highway vehicles ADS technology, and motorsport vehicles.  The methodologies developed by GCAPS have been used to quantify and improve the compounds and tread pattern designs of motorsport tires. 

Motorsport tyre design requires an in-depth knowledge of tyre response, irrespective of the vehicles their placed on. Pirelli faces a new challenge ahead of the 2022 season relative to tyre design, the new vehicle aero package coupled with a change in tire size from a 13-inch to 18-inch diameter wheel. With overall tyre diameter increasing from 660mm to 720mm (~3-inch difference), a reduction in sidewall height inevitable, requiring structural changes to the tyre to maintain current performance demands and removing the team’s ability to rely on historical data increase the challenges for understanding the tyre.. Teams use historical data through race events, practices, and testing to apply setup configurations to the car. Since there is no historical data for the new tyre designs, teams will rely on testing data from both on-track and laboratory environments. It is imperative that testing be performed at a facility containing the resources and capabilities to match conditions seen on track. GCAPS provides this framework to their motorsport’s customers by removing speed compensations, helping improve vehicle setup decisions, and optimizing overall performance.

Over the years, GCAPS has developed and implemented processes, test procedures, and processing tools to improve quality assurance for their customers. These methods are used to evaluate machine health, repeatability, and data quality, which is the reason GCAPS customers can collect such comprehensive data over the span of almost a decade and trust its validity. Yearly machine calibrations are completed by GCAPS to ensure machine repeatability, giving them explicit knowledge of system components and capabilities. For their global customer’s needs, GCAPS understands the importance of time and accuracy with respect to traveling schedules and deadlines, offering adjustable operating hours and virtual attendance options to remain flexible.

In January of 2013, Goodyear Racing became GCAPS first motorsports customer, and have consistently used GCAPS capabilities to improve tyre development, becoming even more prevalent in Goodyear’s development of the new 18-inch diameter tyre being implemented in the 2022 NASCAR season (Figure 4). GCAPS continues expanding their motorsports customer base, including a variety of racing series’ from IMSA to Formula 1, and notable customers which include Pirelli Motorsports and Alpine F1. GCAPS LTRe provides an asset to the motorsports industry and is used by championship series’ across the globe. So, why shouldn’t you?

Eurogrip Tyres, the leading tyre manufacturer in India, showcased its premium two-wheeler tyres at the 17th edition of Feria 2 Ruedas (F2R) International Motorcycle exhibition held at Plaza Mayor, Medellin, Colombia. The dates of this high-profile business event in South America's two-wheeler sector are 15–18 May 2025.

For more than 17 years, the Feria de las 2 Ruedas (F2R) has been the leading motorcycle industry event in Latin America. The expo, which takes place every year in Medellín, Colombia, is a vibrant venue for commerce, innovation and growth in the motorcycling sector.

Denka Company Limited announced it would record an extraordinary loss of approximately 16.1 billion yen (£85.8 million) as an impairment on manufacturing facilities at its US subsidiary. It will indefinitely suspend chloroprene rubber production at the Louisiana plant.

The Japanese chemical manufacturer, which holds a 70 percent stake in Denka Performance Elastomer LLC (DPE), cited mounting operational challenges, including unexpectedly high costs for pollution control equipment and declining production volumes at the American facility.

“DPE has faced significant cost, production and other challenges at its facility in the United States,” the company said in a statement. “Rising costs are attributable to, among other factors, identification, design, purchase, installation, and operation of pollution control equipment to reduce chloroprene emissions that DPE did not anticipate being required when it acquired the facility from E.I. DuPont de Nemours and Company.”

The subsidiary was established in December 2014 and acquired the chloroprene rubber business from DuPont in November 2015. The Louisiana facility was intended to serve as a second manufacturing site in North America, complementing Denka’s Omi Plant in Itoigawa, Niigata, Japan.

However, according to the company statement, DPE has struggled with multiple operational issues, including “rising energy costs and a shortage of qualified staff necessary to operate new pollution control equipment and implement other emission reduction measures. “

Production volumes have declined partly due to “operational restrictions arising from the pollution reduction measures and unscheduled plant outages associated with supply chain disruptions and severe weather events,” Denka said.

The company noted that these challenges, combined with changes in the global economic environment for chloroprene rubber, have pressured profitability, making near-term improvement difficult.

Denka confirmed that DPE employs 250 people as of December 2024 and will not restart its chloroprene rubber manufacturing facilities following a regular maintenance shutdown. Instead, “all options for the business, including a potential sale of the business or its assets, will be considered,” the statement said.

The company emphasised that “no decision regarding a permanent closure of the facility has been made at this time.”

Customers will continue to be supplied from current inventories and production at the company’s Omi Plant in Japan.

DPE is 70 percent owned by Denka USA LLC, a wholly owned subsidiary of Denka Company Limited, and 30 percent by Diana Elastomers, Inc., a subsidiary of Mitsui & Co., Ltd.

Yokohama Rubber reported a 56.9 percent year-on-year decline in profit attributable to owners for the first quarter of 2025, despite posting a 9.0 percent increase in sales revenue.

The Japanese tyre maker recorded a profit of 8.53 billion yen for the three months ended 31 March, down from 19.8 billion yen in the same period last year. Business profit fell 3.2 percent to 24.07 billion yen, while sales revenue rose to 275.12 billion yen.

The company maintained its full-year forecast, projecting an 11.4 percent increase in sales revenue to 1.22 trillion yen and an 8.8 percent rise in profit to 81.5 billion yen for the fiscal year ending 31 December 2025.

Yokohama Rubber attributed the profit decline to one-time costs related to its February acquisition of Goodyear’s off-the-road (OTR) tyre business, which it purchased for approximately 143 billion yen.

“Profit from existing businesses was strong,” the company said in its earnings statement. “In addition to increased sales volume for the company’s consumer tyres, mainly in overseas markets, and continued expansion of sales of high-value-added ADVAN, GEOLANDAR, and Winter tyres as well as high-inch tyres, profit was boosted by the MB segment’s MIX improvements and structural reforms.”

The tyre segment, which accounts for 91percent of the group’s consolidated sales revenue, saw a 10.4 percent increase in sales to 250.32 billion yen. Original equipment tyre sales were higher year-on-year, driven by “strong sales in Japan of vehicle models equipped with YOKOHAMA tyres and expansion of shipments for Chinese automakers’ new energy vehicles,” the company said.

Replacement tyre sales also increased, supported by higher sales of summer and winter tyres in Japan, increased sales of high-inch tyres in Europe, and stepped-up sales efforts in Asia.

The MB (Multiple Businesses) segment, which represents 8.4 percent of total sales, experienced a 3.2 percent revenue decline to 23.02 billion yen. This was attributed to lower demand from construction machinery makers in Japan and automakers in North America.

The company described an “upbeat” business sentiment in Japan for the quarter, noting that “a steady recovery in inbound demand and increasing orders for construction and logistics projects compensated for weak consumption by domestic households curbing spending in response to rising prices of consumer goods.”

Overseas, the company observed rising inflation concerns weighing on consumer spending in the United States, while in Europe, “manufacturing industries are rebounding and corporate business sentiment is improving.” In China, personal consumption was boosted by the Spring Festival holiday, but high US tariffs “reduced China’s exports and created uncertainty about the future that is weakening industrial activity.”

Swedish speciality chemicals firm Nynas reported solid financial results for 2024, posting an Adjusted EBITDA of 1,333 million Swedish kronor, marginally higher than the 1,316 million kronor recorded in 2023.

The company, which specialises in naphthenic speciality oils and bitumen products, attributed its performance to operational efficiency and commercial success in its niche markets.

“We are delighted with the progress made during 2024, evidencing our right-sized cost base and a more targeted commercial and manufacturing footprint. We have redefined our strategic direction, positioning Nynas as a speciality chemicals company, enabling the energy transition and setting our course for 2035,” Nynas CEO Eric Gosse said in a statement.

The firm highlighted strong cash generation from operations, which it said would support planned investments and longer-term growth initiatives. Nynas also mentioned the ongoing transformation of its Harburg site with plans to monetise the asset eventually.

All three of the company’s production facilities maintained high operational reliability between 95 percent and 99 percent. The Nynäshamn refinery achieved a notable milestone: in May 2024, it set a new monthly production record for naphthenic speciality oils at 42,000 tonnes.

Strategic pivot towards sustainability

Nynas outlined a strategic shift focused on higher-margin speciality materials with sustainable characteristics. The company aims to strengthen its position in European markets through innovation and sustainability initiatives.

“Nynas is uniquely positioned to contribute to the energy transition. Our strategy reflects our purpose to advance a more sustainable society, and our product development pipeline is fully aligned with this goal," Gosse added.

In 2024, the company received an EcoVadis Gold rating, placing it in the top 5 percent of globally rated businesses for sustainability performance.

With consecutive years of strong financial performance, Nynas indicated it continues to monitor debt capital markets to optimise its capital structure “at the appropriate time potentially”.

The Swedish chemicals producer noted that, having ceased operations in the United States in 2022, it remains largely insulated from recent global trade tensions surrounding US import tariffs. The company imports only minimal feedstock from America, shielding it from potential cross-border trade disputes.
