BWI Group has introduced an automated mode for its Semi-Active Roll Control (SARC) system, designed to address the weight challenges of modern SUVs and battery electric vehicles (BEVs). The update allows a vehicle's anti-roll bar to disconnect and reconnect on demand while driving.

For the unversed, BWI Group was incepted in 1909 as Dayton Engineering Laboratory Company (Delco). It is said to have created the first reliable electric self-starter for the global automotive market, and is now currently owned by China’s Beijing West Smart Mobility Zhangjiakou Automotive Electronics Co, led by Zhang Jia Kou Financial Holding Group (ZJKFH) and an assembled syndicate of key investors.

The SARC system aims to resolve the engineering conflict between ride comfort and handling. As SUVs now account for over half of European car registrations and BEVs weigh significantly more than internal combustion counterparts, chassis engineers have historically used stiff stabiliser bars that can compromise comfort.

Operational Data and Speed

The new mode uses vehicle data – including steering angle, speed, lateral acceleration, and yaw rate – to manage the anti-roll bar. During high-speed cornering, the system reconnects the bar in less than 200 milliseconds. When the bar is disconnected during normal driving, the vehicle maintains a more compliant ride.

At the centre of the technology is a rotary actuator and a self-contained hydraulic mechanism. Unlike mechanical alternatives, this hydraulic setup allows for connection and disconnection even when wheels are positioned at different heights. The system also features self-centring technology to ensure engagement across all suspension travel.

SARC is currently in production for several platforms, including the GWM Tank series. BWI Group expects the automated functionality to increase adoption in the SUV and BEV sectors, where managing vehicle mass is a priority for manufacturers.

Bruno Perree, Engineering Manager, BWI Group, said, “Chassis engineers are continually trying to improve road handling and comfort, but the two goals are often incompatible. The latest update to SARC removes that compromise, allowing engineers to optimise the roll bar purely for handling as it will be disconnected the majority of the time. This not only improves comfort but also adds significant off-road capability, which can be a key competitive differentiator in a crowded SUV market.”

HS HYOSUNG ADVANCED MATERIALS has taken part in JEC World 2026, the premier global composites exhibition, held from 10 to 12 March 2026 at the Paris Nord Villepinte Convention Center in Paris, France. The company’s participation focuses on its advanced carbon fibre-based composite technologies, applicable in the automotive sector, alongside other key industries such as aerospace, construction and renewable energy.

Having consistently attended this prestigious event since 2013, the company is using this year’s platform to showcase innovations that cater to both high-performance and large-scale industrial needs. A central part of its display includes high-strength 3K carbon fibre, notable for its enhanced tensile strength, making it suitable for demanding applications in automotive components, drones, aviation and civil engineering. To address the requirements of broader industrial markets, the company is also featuring its 48K Large Tow carbon fibre, designed for use in wind power and the automotive industry.

At its exhibition booth, HS HYOSUNG ADVANCED MATERIALS is demonstrating the practical versatility of its materials by displaying finished products such as drones and high-pressure hydrogen storage tanks, both manufactured using its carbon fibre. This approach underscores the material’s critical role in lightweighting and high-strength applications, including the growing field of hydrogen mobility.

Carbon fibre, which is both a quarter of the weight of steel and significantly stronger, is seeing rising demand for pressure vessels, automotive parts and wind turbine blades. As the first Korean company to domestically develop high-strength carbon fibre under the TANSOME brand in 2010, HS HYOSUNG has been operating its Jeonju plant since 2013 and is now expanding its production capabilities into China and Vietnam. Building on this foundation, the company aims to solidify its status as a global leader, particularly following its 2022 development of H3065, an ultra-high-strength carbon fibre over 14 times stronger than steel, intended for advanced aerospace and automotive sectors.

Jim Dal Lim, CEO, HS HYOSUNG ADVANCED MATERIALS, said, “JEC World 2026 is an ideal platform to showcase our outstanding technologies to a global audience and discover future collaboration partners. Through this exhibition, we will expand cooperation with global customers and actively explore new business opportunities in the composites market.”

Advent HoldCo has confirmed it will not acquire the LANXESS stake in the ENVALIOR joint venture in 2026. This follows a tender submitted by LANXESS in September 2025. Advent cited financing conditions as the reason for the decision.

The tender and purchase periods for the shares in 2027 and 2028 remain in effect. LANXESS will continue its role in the joint venture. The company attributes the development of ENVALIOR to market recovery within the sector, synergies between the companies and consolidation among competitors.

LANXESS stated it remains financed despite the absence of sale proceeds in 2026. The company maintains a cash position and credit lines totalling more than EUR 1.35 billion. Repayment of the bond maturing in October 2026 is secured.

The company stated that it maintains access to debt capital markets and debt reduction remains its top priority.

European automotive component supplier Marelli has launched its new generation Port Fuel Injection Engine Control Units (PFI ECUs) for petrol, flex fuel (ethanol, methanol and synthetic fuels) and Compressed Natural Gas (CNG) applications, specifically targeting the India, Brazil and EMEA markets.

The ECUs are designed, validated and produced locally in each region. This portfolio utilises Marelli’s 20-year history in flex fuel and bi-fuel technologies to address regional vehicle architectures and emission regulations.

The new ECUs incorporate the Infineon AURIX TC3x automotive microcontroller to manage multitasking and processing. The hardware and software are built to support calibration, homologation and customer-specific tuning.

Key technical features include:

• Processing: Integration of Infineon’s AURIX TC3x for reliability and fast processing.
• Architecture: Open system allowing third-party applications and Firmware Over-the-Air (FOTA) updates.
• Safety & Security: Compliance with ISO 26262 ASIL D functional safety standards and anti-tuning protection.
• Control Channels: Up to eight gasoline injector drivers and four CNG injector drivers.
• Diagnostics: OBDII diagnostics and wide-range O2 Universal Exhaust Gas Oxygen (UEGO) sensors for air/fuel ratio monitoring.

By localising production and R&D, Marelli aims to provide automakers with reduced costs and faster implementation times. The units manage all engine requirements, including integrated combustion algorithms and emission control strategies to meet local regulatory standards.

Giovanni Mastrangelo, Head of R&D for Marelli's Propulsion business, said, "As adoption speeds for propulsion technologies vary, Marelli continues to support customers across the powertrain spectrum. In markets where internal combustion engines remain relevant, our new engine control units enable greater efficiency, emissions reduction, and versatility. This reflects our system-driven approach and know-how in vehicle control, conventional and alternative fuel injection technologies and transmission systems.”
