Extinction is looming for manual gearbox cars as well as diesels by the end of the decade, trend analysis by data experts has revealed.
Vehicle Data Global (VDG) - which powers systems across the automotive sector with technical and market data - says that although diesel market share has fallen most, the decline of manual transmission is accelerating faster.
Analysis also reveals that the decline of manual transmission is underpinned by consumer preference as much as Britain's changing model mix. The company analysed millions of existing market data points to identify that it is not only the replacement of ICE cars by hybrid and EV models driving the decline of manual, but that share has halved since 2016 even for petrol and diesel cars.
Both trends suggest near-simultaneous extinction as soon as 2030, with research, development and production costs increasingly seen as unviable by manufacturers. It means the end of the traditional 'motorway mile-muncher' that dominated fleets and private sales just a decade ago, with diesel's 92% collapse since 2016 and manuals standing at just 13.7% of the market so far this year.
VDG says that the moment is approaching when declining demand is overtaken by hard economics for manufacturers reluctant to maintain the overheads and tooling to produce both systems. While diesel's decline is widely recognised, trend data suggests that the prospect of survival for manual gearboxes is even slimmer, and VDG predicts that both may end simultaneously in the car market by the end of the decade.
The picture remains very different for light commercial vehicles, where diesel continues to dominate and manual gearboxes still commanded a 63% share last year, compared with fewer than one in five cars.
Although the steep decline in manual car transmission was first sparked by growing market share for hybrids and EVs - with automatic transmission almost by default - consumer choice is accelerating the trend. Even among ICE car buyers, where consumers still actively have a transmission choice, manual share has fallen from 55% in 2019 to 34% in 2025.
With manufacturer conversion to automatic drivetrains gaining momentum, the economics of developing and building manual gearboxes may soon be unsustainable, VDG believes.
The moment is fast approaching when the economics of maintaining a manual transmission option don't add up, given the R&D, certification and other overheads of developing and refining gearboxes, even if there remains some demand in the market.
Based on current trend data, between 5% and 10% of cars will theoretically still be manual by 2030.
But manufacturers will be looking hard at whether maintaining manual gearbox programmes for a shrinking share of the market makes economic sense, while they manage the overall pressures of conversion from ICE and competing with international market entrants in the EV sector.
