1 CONTINOUSLY VARIABLE TRANSMISSION (CVTs)
CVTs are pulley-based transmissions used in small vehicles with small engines. They offer a similar driving experience to automatic transmissions but use a different mechanism. CVTs use a system of belts and pulleys to produce an infinite range of ratios. The computer adjusts the pulley to create the optimal ratio for specific driving situations. This system allows for strong and seamless acceleration.
Pros of CVTs
1 smoothest ride
2 greatest fuel efficiency
3 faster response
Cons of CVTs
1 unusable in off-road conditions
2 no ability of engine breaking
2 Semi automatic Transmission
It is a clutch less manual transmission that provides an alternatives to its automatic or manual counterparts this transmission is practically identical to a manual one in a typically manual vehicle the driver steps down on the clutch pedal when they want to change gears the clutch pedal is connected to the transmission through cables and pipes in a semi automatic there is no clutch pedal instead there is computer that uses processors and sensors to automatically depress the clutch when the driver signals by shifting the gear stick the vehicles computer manages engine torque, speed. accelerator pedal position and other function driving a semi automatic car would feel very similar to a manual drive except although semi automatic do have things in common with other typical transmission and they are also very different with their own sets of benefits and drawbacks
Pros of Semi automatic transmission
1 smooth shifting
2 less in efficiency in shifting
Cons of semi automatic transmission
1 expensive to maintain and repairs
3 Dual clutch transmission
There are separate clutches for both odd and even gears which allows for incredibly fast shift these gearboxes can generally operated in a fully automatic mode with paddles on the steering wheel
Working of dual clutch transmission
It offer cutting edge performance with lightning fast gear change that a pure manual just cannot match these gear box are found in race car and high sports cars they are quite expensive this disadvantage is magnified by their extreme complexity which lead to more frequent and costly repairs
