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, multi-spark ignition, integrated multi-motor drivetrains and vehicle auxiliary drives are disruptive technologies that are in the early stages of application and should be tracked closely. Solar range extenders, turbocharger shaft bearings, and multi-lamellar clutches are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are auto-transmission lubrication circuits and electroluminscent vehicle displays, which are now well established in the industry.
Innovation S-curve for the automotive industry
Variable valve actuation system is a key innovation area in automotive
A variable valve actuation (VVA) system is a mechanism that enables precise control of valve timing, lift, and duration in an internal combustion engine to optimize engine performance. It allows for greater flexibility in combustion chamber design, improving fuel efficiency, reducing emissions, and increasing power output.
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 65+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of variable valve actuation system.
