The automotive industry continues to be a hotbed of patent innovation. Activity in liquid cooled propulsion is driven by temperature management, increased power density, extended lifespan, and improved energy efficiency, and growing importance of technologies such as coolant circulation systems and heat exchangers. In the last three years alone, there have been over 720,000 patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: liquid cooled propulsion.

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

Liquid cooled propulsion is a key innovation area in automotive
Liquid cooled propulsion refers to a system or method of cooling the components of a propulsion system using a liquid coolant. It involves circulating the liquid coolant through the propulsion system to dissipate heat generated during operation and maintain optimal operating temperatures. This cooling system aids in averting overheating, thereby enhancing the efficiency and longevity of the propulsion system.
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 210+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of liquid cooled propulsion.
Key players in liquid cooled propulsion – a disruptive innovation in the automotive industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
