CVT Transmission, An Innovation That Changed The Way We Drive, It All Started Back In 1490 With A Sketch By Leonardo Da Vinci. But It Was Milton Reeves In 1879 Who Got His Hands Dirty And Created A System Of Adjustable Pulleys, Revolutionizing The Industry.

The CVT, or continuously variable transmission, is that type of gearbox that makes driving smoother than butter on hot bread. It uses pulleys and a belt to create a feeling of “infinite gears,” without the jolts of conventional gear shifts. And it’s not just in cars, you know? Modern scooters also use this technology.

The Evolution Of The CVT And Its Challenges

In the 1950s, the Dutch company DAF put the CVT in cars with the Variomatic system. It was simple, but the belts were a headache. It wasn’t until the 1980s that things got serious, with the invention of more durable belts, and the Subaru Justy was one of the pioneers to use the modern CVT.

The CVT of today is an efficient piece of machinery and helps save fuel, but not everyone likes it. Some people find driving with a CVT somewhat boring, and some automakers even simulate gear shifts to liven things up.

Variable Transmissions In Heavy Industry

In heavy industry, the CVT also makes an appearance, but in a different way. We have the hydrostatic transmission, used in machines like harvesters, and electric traction, common in trains and ships. These systems are more robust and can handle the strain of heavier work.

In the world of tractors, variable transmission is also a success. The German company Fendt, for example, created a system that combines hydraulics with gears, showing that the CVT can be strong and resilient.

The Evolution Of The CVT And Its Challenges

Variable Transmissions In Heavy Industry

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

With 70 tons of rock removed by hand and an 800-year-old abandoned cave, a former businessman transforms a dark shelter into a modern home carved in the heart of the forest.

Scientists have created a material six times lighter than air, 75 times lighter than styrofoam, and that becomes stronger the more it is compressed: aerographite seems impossible, but it can reinforce structures, batteries, and satellites.

Zawoja, the longest village in Poland, stretches for 18 km between mountains, can take an entire day to cross on foot, and brings together houses, roads, and strips of land in one of the most curious rural formats in Europe.

NASA separated two identical twin brothers for 340 days and turned one of them into a human laboratory in space: the experiment revealed changes in genes, immune system, microbiome, and cognition, as well as a surprising “rejuvenation” effect that exposed the impact of living away from Earth.

Brazilian National Team idol aims for high luxury in Florida and buys 2 apartments at once for R$ 25 million in a 45-story skyscraper, featuring a private beach club, wine bar, karaoke room, and virtual reality simulator.

China and Japan create a brain implant thinner than a hair, with 128 channels and data density ten times greater than any previous hydrogel, which operated for 550 days in rabbits without causing inflammation or scarring.

Coffee grounds turn into fuel in just 90 seconds, eliminating the need for drying, removing sulfur compounds, and generating biochar with energy similar to anthracite coal in a process created by scientists in South Korea.

Peugeot 408 Griffe 2015 combines a turbo engine, 0 to 100 km/h in 8.3 seconds, a 526-liter trunk larger than many compact SUVs, leather, multimedia, cruise control, and a sunroof, but it remains off the radar among fully equipped used cars.

Chevrolet Onix leads the efficiency ranking among flex-fuel cars by Inmetro, achieves almost 18 km/l, and costs less than R$ 100,000.

Non-alcoholic beer is not always 0.0%: the drink can appear on the breathalyzer, result in a fine of R$ 2,934.70, suspend the driver’s license for 12 months, and even lead the vehicle to be impounded.

A burned Ferrari seemed destined for scrap, until a company removed the V8 engine, installed three electric motors, and transformed the old sports car into the 308 GTE with a 47 kWh battery.
