The automotive industry continues to be a hotbed of innovation, with activity driven by the need for cabin comfort, and emergence of autonomous vehicles, and growing importance of technologies such as machine learning and artificial intelligence. In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in Automotive: Vehicle PTC air heaters.

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 stabilising 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.
290+ 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 619,000 patents, there are 290+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, resilient spoke wheels, auto-transmission lubrication circuits, and ignition switching engines are disruptive technologies that are in the early stages of application and should be tracked closely. Engine purge actuators, electro-dynamic braking, and adsorptive vapour recovery system estimation are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are collision avoidance braking control system and direct injection type engines, which are now well established in the industry.
Innovation S-curve for the automotive industry
Vehicle PTC air heaters is a key innovation area in automotive
Positive temperature coefficient (PTC) air heaters are self-regulating electric heaters used in addition to the heater core and are usually placed after the heater core or sometimes in ducts for footwell heating. PTC air heater cores have been added to climate control systems to compensate for insufficient heating on high-efficiency engines.
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 20+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of vehicle PTC air heaters.
