This 1993 Williams has one of the most unusual gearboxes ever in F1. Rather than 8 gears like modern F1 cars, it had an ingenious mechanism that could smoothly change through an infinite number of gear ratios.
It promised to make the car easier to drive, more efficient and much, much faster.
It's called a Continuously Variable Transmission, a CVT. It’s not a new thing, but was new to something as powerful as a 90s F1 car.
It meant the car was always in the right gear and could make best use of the engine's power, delivering all 850 horsepower, all the time.
There are many different types of CVT - with more clever ones being trialed in cars all the time. They’re not new though, and are often used on anything from a Pillar Drill to a Scooter.

But this is the one that was used in the Williams car, it’s essentially two pulleys, with a belt connecting them. One pulley is connected to the engine, the other to the wheels.
Each pulley has one side fixed in place, whilst the other side can move.
When the pulley is squeezed together, it forces the belt up the cone, the same as shifting to the largest cog on the back of your bike.
The same happens in reverse, pull the two sides apart and the belt moves to the bottom, similar to the smallest cog on a bike.
If you were to hold the pulley somewhere in the middle, you can have any gear ratio you like, as the belt can deliver power anywhere on the surface of the pulleys.

      @Peter L Yes I tried one of those in the 80's was pretty cool, but not a very popular option. Same with Volvo and DAF. They had some models with the CVT. Went as fast backwards as it did forwards.

    The picture of the Williams F1 car in the museum is actually not the Williams museum, but the DAF Trucks museum in my hometown. DAF is located in Eindhoven, the Netherlands and this transmission concept is developed by DAF. The old DAF cars had this transmission in their road cars and therefore they could drive backwards and forwards at the same pace. We had a “Backwards Driving Race” at Circuit Zandvoort where these small DAF cars were used to race the circuit facing backwards on the grid haha.. good old times!

    Such an interesting design and extremely practical. I was a mechanic for Saturn. And some of the Vue and Ion models used CVT transmissions. They had their issues, but when they worked they were very efficient. I think most of the problems actually came from improper use rather than design. But when they went they sent the belt teeth all throughout the transmission. And needed to be completely replaced.

    Honestly, I don't think that Williams or any other team used such type of 'gear box' in F1. I know for some 50 years that it was used in street cars DAF, and that's what is shown in this video too. And I read then that this system is not usable by larger cars, cars with stronger engine. Now, imagine how is it then possible with some 700 HP F1 car in 90-es . Maybe yes, but not with single belt. And something related. I watched F1 races on track in 1993 and 1994, on location with many corners. And I could hear work of cars very well, as not possible on TV. Williams was extremely fast with gear changes, much better than any other. Just to mention that Ferrari was only one with 12 cylinder engine, and that was much higher engine sound. So, Williams probably used some digitally controlled gear box control, what could sync. gear speeds much faster than usual solutions. I guess, it became standard years later. And even if it is true, is there real reason to ban it ? Surely, automatic gearbox was forbidden, but this could be with manual control. Saying than gear count is limited too - yeah, but here no gears :-) Well, something like with DAS last year. Anyway, as said, hmmm ... Good way to pull attention.

    Wrong explanation of torque/horsepower. CVT allows access to "unavailable horsepower" that cannot be got with fixed gear boxes because maximum acceleration in any FIXED gear (speed open) is always at the torque peak while maximum acceleration at any fixed speed(gearing open) is always found at peak horsepower. A fixed ratio trans can never give access to peak horsepower cvt can. Hence the term "Unavailable Horsepower".

    CVT on F1 car makes perfect sense - cost is not prohibitive, it only has to survive one race so endurance is not a problem compared to daily commuter, in F1 people don't care about the sound but care about lap times, when executed properly it's actually lighter than standard gearbox :)

    I completely understand f1 parts are some of the strongest that exist, but most CVT cars are 4cyl, and CVTs tend to fail very early compared to standard transmissions even with those motors. They often fail under high load due to overheating like hard driving or going up steep hills that are long. I imagine an f1 car would make this problem even worse, and while the cvt may provide fast lap times it would likely start to slip and slow down as the race were to progress. My opinion would be f1 banned them to prevent manufacturers from going down a rabbit hole and engineering cars they would have to ban after a few seasons of development.

    A few facts: 1. CVT Was invented by DAF ( = van Doorne Automobile Factory, which most people nowadays know as truck builder), but who in the 50-s to 70-s produced small cars for the low budget 2. They invented CVT actually as a way to make driving easiers for people who found changing gears to difficult 3. For that reason the little DAF's in Holland where called "granny shakers with garterbelt propulsion" (free translation) 4. The original CVT used a (rubber) pulling belt reinforced whith steal cables. 5. These however were not a able to withstand more about 70 HP tops 6. To make them stronger DAF invented and patented a new type of belt, which does not pull, but actually transmits the power by PUSHING (!) 7. It does this by the this by way of stacks of small steel plates which are slid onto the belt 8. These are the steel plates that you actually see in the animation 9. Because has a very high compressive strength a great of torque and power can be transmitted in this way 10. That, however, did not solve some other problems like wear and tear, and the like
