The automotive industry continues to be a hotbed of patent innovation. Activity in dual-drive electric propulsion is driven by increased demand for fuel efficiency and reduced emissions, advancements in battery technology, power electronics, and control systems. The rising demand for electric vehicles, government funding for research and development, and partnerships between automakers and suppliers are further driving innovation. Silicon carbide (SiC) power electronics, integrated electric motors and gearboxes, torque vectoring control systems, and wireless charging systems are key technologies in dual-drive electric propulsion for the automotive industry. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: dual-drive electric 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, 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.
