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 the maturing innovation areas are kinetic energy recovery system (KERS) and plasma-jet ignition, which are now well established in the industry.
