The automotive industry continues to be a hotbed of patent innovation. Activity in variable transmission electric vehicle (EV) drivetrains is driven by rising demand for EVs, emissions regulations, materials science advancements, and cost-effective manufacturing processes, and growing importance of technologies such as continuously variable transmission (CVT), dual-motor systems, beltless CVT, and integrated systems. 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: variable transmission EV drivetrains.

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.
Innovation S-curve for the automotive industry
Variable transmission EV drivetrains is a key innovation area in automotive
Variable transmission EV drivetrains refer to drivetrain systems in electric vehicles that use in-wheel motor systems to generate power and provide varying gear ratios for efficient power delivery. These drivetrains make use of motors placed in the wheels of an EV, which can provide more precise and efficient power delivery to the wheels.
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 30+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of variable transmission EV drivetrains.
