However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

300+ innovations will shape the automotive industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over one million patents, there are 300+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, integrated multi-motor drivetrains, electric power steering (EPS), and post-collision handling are disruptive technologies that are in the early stages of application and should be tracked closely. Variable compression engines, V2V distance monitoring, and turbocharger shaft bearings are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are kinetic energy recovery system (KERS) and plasma-jet ignition, which are now well established in the industry.

Innovation S-curve for the automotive industry

Automotive extrusion moulding is a key innovation area in automotive

Automotive extrusion moulding is a manufacturing process where a material is extruded and then moulded into specific shapes required in producing various automotive parts such as foam insulation, food casings, and insulators. The process involves the use of materials such as polyolefin resin, chlorinated polyethylene resin, and glass fiber reinforced polypropylene-based resin to produce foam articles that are light in weight, with good dimensional stability, bending rigidity, and excellent microbial adherence and affinity for pore areas.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 30+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of automotive extrusion moulding.
