Button Census

Documented and in-progress records. Basic records are left out because they carry no cockpit detail. Each generation counts once, in the 5-year bucket of its launch year, however long it stayed in production.

One type per generation, as recorded by the archive's editors: physical (dedicated knobs or buttons), mixed (some physical, some on the screen), on the touchscreen, or a touch-sensitive panel such as capacitive sliders. Generations without a recorded type are left out of the shares and counted as “Not recorded” in Table 1.

A generation counts as touchscreen when any of its infotainment systems lists touchscreen input. The share is taken of generations that list at least one input mode, so a car with buttons and a touchscreen counts as touchscreen.

The number of physical buttons and knobs on the dashboard and centre console, counted by an editor from a photograph in the archive, zone by zone: beside the steering column, the radio or head unit, the climate panel, the rest of the centre stack and the console. Table 4 names the version photographed and links the photograph, so any count can be checked.

1. Count every physical control on the dashboard and centre console that is operated on its own: push buttons, rockers and toggles, knobs, rollers, heater levers, and each key of the factory radio or head unit, a phone keypad included.
2. A rocker, a plus and minus key or a four-way pad counts once. Keys that move separately count once each.
3. A push button counts whatever it does. A pull handle, a latch or a reset stem inside the instruments does not.
4. Leave out the steering wheel, the column stalks, the doors, the seats and the roof console; the gear lever or selector of any kind and the handbrake; air vents and their adjusters; the lighter, ashtray and sockets.
5. Touch-sensitive keys with no moving part do not count, and nothing on a screen does.
6. Count the car as built. Leave out a radio or other equipment fitted later.
7. Count only what a photograph shows. Where part of the dashboard is hidden, say so: the count is then a minimum.
8. Note the trim, market and model year, since counts often differ between them.
9. Note how the climate controls work: knobs, buttons, the touchscreen or a touch panel.

Counts are approximate. Trims, markets and model years differ, a wheel rim or gear lever can hide a control, and a photograph cannot always show whether a flush key moves.

In November 2026 a second editor recounted 16 of the cars without seeing the first counts. Half of the pairs differed by 3% or less, and 14 of the 16 were within three buttons. Two differed by more than 15%, where the photographs showed two versions of the car or a phone keypad that slides out of the dashboard. Those two counts are not published, and neither are counts where much of the dashboard was hidden.

98 generations (48 documented, 50 in progress): 88 with a recorded climate-control type, 74 with recorded infotainment inputs and 57 with a button count. The climate figures cover 17 makers, and the largest share comes from BMW: 15 of 88 generations (17%).

Buckets with fewer than 5 generations with a recorded type are hatched in the figures and set in secondary text in the tables. The summary compares them only when no better-sampled buckets exist, and marks them as small samples when it does.

• The archive is not a random sample of the car market. It began with notable and enthusiast cars, so some makers and periods are over-represented.
• Nothing is weighted by sales: a low-volume coupé counts the same as a high-volume saloon.
• One value per generation. Trims, markets and mid-life updates can differ; the record usually describes the version its sources cover best.
• The most recent bucket is incomplete, because models in it are still being launched.
• All figures are recalculated whenever the archive changes.
