![]() ![]() It’s too smooth : Many drivers really enjoy the feel of a good stiff standard transmission. This so-called “rubber band” effect is being engineered out of newer CVT systems. The engine revs up for a beat before the transmission catches up. It feels different : People who are used to driving standard transmission cars can be unsettled by a slight delay after applying the throttle to a CVT car. Its lighter weight contributes to the overall fuel efficiency gains enjoyed by CVT cars. Simplicity of design : Because of its relatively simple design, a CVT is easier to assemble and less costly than a traditional automatic transmission, which is made up of hundreds of complex parts. ![]() Department Of Energy estimates that vehicles with CVTs perform at 3% – 4% more fuel efficiency, saving about $700 – $900 over the life of an average vehicle. Smoother ride: Cars with a CVT glide effortlessly through gear ratios while accelerating or slowing down, eliminating the jerking feeling that results from shifting gears in traditional transmissions.įuel efficiency: The U.S. An excellent way for you to understand better would be to test drive a new or used CVT automobile at a local dealership, but for a quick primer here are some pros and cons to keep in mind. While searching the Rocket Auto SM Inventory, be sure to ask the seller if any individual vehicle you’re looking at has a CVT.Ī car with a CVT is great for some people, but might not suit others. While CVTs are very popular on the Japanese market, they are becoming more common in the United States on such models as the Honda Civic, Subaru Forester and Toyota C-HR, to name just a few. There is really no shift, which is why the ride feels smoother. To put it another way, a traditional transmission jumps between a fixed number of gears, whereas a CVT glides between an infinite number of gears. Unlike gears, which shift in increments, the belt and the width of the pulleys are constantly changing depending on the power the vehicle needs. The input pulley takes power from the engine and, by way of the connecting belt, turns the output pulley, which turns the axel and thereby the wheels. Instead of using gears, a CVT has two pulleys connected by a belt. The continuous slide of the pulley is less jerky than shifting gears and allows the car to accelerate smoothly and more efficiently.Ī CVT is similar to an automatic transmission in that it does not require input from the driver. The difference between the width of the engine-based pulley and the wheel-directed pulley is the CVT’s version of having different gear ratios. The belt “slides” up and down between the wide and narrow ends of the pulley depending on how much engine power the wheels need. A CVT employs two cone-shaped pulleys connected by a belt, with one pulley connected to the engine’s power and one that delivers that power to the wheels. While a traditional transmission uses the motion of larger and smaller gears to turn the axel depending on driving conditions, a CVT uses a belt and pulleys to turn the wheels. ![]() When the bolt is looser, you could switch to a shorter wrench which turns the bolt faster (like a higher gear at high speeds).Ī continuously variable transmission does not employ mechanical gears, but it accomplishes the same task as a traditional transmission, just in a different way. This could also be referred to as higher torque. It provides more mechanical advantage and is best when trying to get the bolt loose (like a lower gear at low speeds). A low gear would be like a really long wrench. Say you are trying to pry loose a really tight bolt. So how do gears work? We’ll put it in language that doesn’t require a master’s in mechanical engineering to understand. Generally the lower the speed of the car, the lower the gear the more speed required, the higher the gear. Modern manual and automatic transmissions usually have between four and six gears. On an automatic transmission, the vehicle has technology that senses which gear is optimal and shifts without driver input. In a manual transmission, the driver decides which gear is optimal and mechanically shifts into that gear. First it might help to explain how traditional transmissions work. ![]()
